The Workbench/shop stock lists. Woodworking (Beginners list)

Just as with the Beginers Electronics Bench I'm writing a list of essential tools for a beginner woodworker.

Just the same as electronics, this is the list of stuff that you'll need to get you started. I'm assuming that you're looking to build small things, by small things I mean enclosures for your projects, hifi speakers, pictures frames or small boxes etc. This list of tools will enable you to build a huge project like a tree house, or a wooden bike, but before you embark on any project like that you need to not only have the basic tools, but also the ability and practice to use them. (there's that word practice again, yes, working with anything and creating anything is a skill, to develop skills you have to work at them. that's the difference between first year/grade and final year projects, you've spent years practising by the time you get to your final year so you've got more knowledge and more skills.)

Anyway, this list should get you started.

A clamp
There are many different kinds of clamps, G clamps, C clamps, sash clamps. clamping devices come in all different shapes and sizes.

The reason that I put a clamp at the top of the list is because I believe that this is the most important thing that you want.
Your project might only be gluing two bits of wood together, unless you want to sit all night holding the bits together by hand, a clamp is essential.

You can also use a clamp to hold a piece of material to a surface as you cut material off of it.
(it's much easier to cut through something when it's held steady!)

You can get an idea of the variety and kinds of clamps available by looking here;
http://search.diy.com/search#w=clamp

As a starter set I'd say that you couldn't go wrong with buying a cheap set of three C clamps. they come in different sizes enabling you to work on a variety of projects sizes.

Cost £5 (total cost £5)

A Saw
You've got a way to put things together, now how about a way to take things apart?

Saws come in all variety of shapes and sizes, and are used for different things.
your average hand saw costs less than £10 and has a blade that can do cross cut (cutting through the grain of the wood), or rip cuts (cutting along the grain of the wood.)

If you plan on making only big things, then a large 9ppi saw is probably all you need that'll rip through wood quite fast, if you're planning on making much finer stuff (furniture for example) you might want a saw with finer teeth, perhaps 14ppi.

What's PPI? PPI means points per inch, it's the amount of teeth on a saw inside of one inch measured along the blade. it's as easy as that.

Saw teeth rip through things by wearing them away, the more saw teeth that there are in a given inch, the finer the teeth will be, and the cleaner the cut that they make will be, though the longer it'll take to get through the material you're cutting, as it'll rip away less material on each pass.

the picture on top represents a 7ppi blade, the one on the bottom a 14ppi blade, the 14ppi blade is clearly much finer.

As a starter, I'd recommend that you get an all purpose hand saw like this
http://www.diy.com/diy/jsp/bq/nav.jsp?action=detail&fh_secondid=9676731&fh_location=//catalog01/en_GB/categories%3C{9372015}/categories%3C{9372043}/categories%3C{9372176}/categories%3C{9392049}/specificationsProductType=hardpoint_saws

Cost £3.50 (total cost £8.50)

There are of course different saws for different jobs, a fret saw is used for cutting shapes as the blade is very thin and can turn corners.
A coping saw has a round blade and can cut up, down and side to side.
A tenon saw has a metal bar that re-enforces the top of the blade to make sure that it doesn't move of flex. As with most tools, different saws are suited to different jobs. I don't recommend buying them all at once, but certainly if you have a specific job that requires a specific tool then you should buy that tool.

Tape measure
Ok, so you can hold your work piece still now (clamped to the kitchen table), and you can cut through it, but how will you need to know where to cut?

Get a tape measure.
Cheap tape measures might lack a cool feature like being able to lock the tape out, but they work just as well at measuring stuff. So just grab a cheap one.

Cost £5 (total cost £13.50)

Square
So now you know where to cut, you'll want to draw a line on the wood that you're cutting, of course you want to make sure that your line is perpendicular to the edge, not going off at an angle, so you'll want to use a square.

http://www.diy.com/diy/jsp/bq/nav.jsp?action=detail&fh_secondid=11247668&fh_location=//catalog01/en_GB/categories%3C{9372015}/categories%3C{9372043}/categories%3C{9372176}/categories%3C{9392047}/specificationsProductType=measures/specificationsSpecificProductType=squares

That set I've linked to has a L shaped piece of metal that you can put on top of a piece of work (where you can't get to the edge) and line up the work with the square, and a thing that is like a ruler, with an adjustable piece of metal on it, the adjustable piece of metal slides in and out allowing you to set it a distance from the end, it also has 90 degree and 45 degree edges.

Cost £10 (total cost £23.50)

Marking
I have of course assumed that you already have a pencil, or a pen to mark your surface with.
this is your choice, you can buy those big square carpenters pencils (and get to feel really manly as you sharpen them with a knife!). You you can go to a pound shop and buy a pack of regular pencils, and a pack of chunky markers, and a pack of fine markers. (for a pound per pack.)

Cost £3 (total cost £26.50).

Hammer
Used the world over for making noise.

There are many many different types of hammer. I've got more than 1 hammer, (cross pein, ball pein, claw, club, rubber).

I'd recommend that you get a few different types of hammer too.
I'd really recommend a 12oz ball pein hammer (the one that looks like it has half a ball on the opposite side to the flat side.)
a 4oz cross pein hammer, sometimes called a pin hammer (the really light weigh one that has a flat chisel like looking part opposite the hammer surface.)
and a 16oz Claw hammer, (the one with a curved surface opposite the hammer face for pulling out nails.)
These hammers will cost £5 - £10 each they all have different uses.
The smallest cross pein hammer is used for fine work, like hammering in veneer pins into some work.
The ball pein is actually more of a metal work type hammer, but I tend to find that I use this the most as the weight of it feels right to me.
The claw hammer is the heaviest and can be used for much heavier work, (driving in big nails). Personally I find that, even though there is only a 4oz difference between the ball pein and the claw hammer, that added weight makes the hammer more unwieldy, and less suitable for fine work. If the hammer is unwieldy then it's harder to control, and you;re more likely to hit your fingers.

Cost £30 (total cost £56.50)

Punch
No, not the drink, the tool, it's basically just a metal rod that you use for pushing nails below the surface, or driving nails to the surface in places where you don't want the hammer face to have any chance in coming into contact with or marking the work that you're doing.
You can just use a really big nail, but since a set of five of these (in different sizes) is only £6 (on DIY.com,) you may as well get the right tool for the job.

Chisel
This is one of those things where you'll really get what you pay for, but also one of those things where good tools cost good money.

For a start I'd recommend (from diy.com) the B&Q value set of three chisels, there are three different sizes, and they are sharp when you buy them at least.
Basically these are good enough. Chisels do get blunt, so you may want to consider a sharpening stone too.

When I first started out I bought the B&Q value set, and used these until they were pretty blunt, you'll know when they get blunt because they become difficult to work with, they don't cut well, require more force, slip more (read between the lines here, blunt tools are difficult to work with, and will slip around on your work piece, i.e blunt tools are more dangerous than sharp tools.) Anyway, later on, when the chisels needed sharpening, I bought a different (better) set, that came with a sharpening stone, That set was more expensive.
I sharpened my value chisels, (which was good), and now I have a set of cheap chisels that I'll happily use for rough work, or work that might hit a nail or something, and a set of nice chisels that I'll use then I know that the wood I'm dealing with it good.

Cost £7 (total cost £63.50)

Drill
I covered drill in my how and where to buy tools and materials post before, the drill you want will really depend on the work that you want to do.
If you're only ever drilling softwood in a garden shed with no power, then a battery drill is ideal.
If you want to drill into hardwood for long times, then you really want a mains powered drill. If you plan on drilling into walls, you really want a hammer drill.
The type you need depends on what you need to do. and the brand you get also depends on what you need to do.
As I've said before, professionals buy DeWalt drills because they are dependable, that tool will likely outlive the person who buys it. They cost a lot, but to a professional they don't cost as much as numerous trips to the hardware store to buy a new drill (because time spent in the store is not time spent on the job.)
If you can afford professional tools, (like DeWalt, or Makita) then by all means go buy those tools. If you find them on sale then you might want to buy them (but even at half price they are often four to five times more expensive than the drill that I normally use).

For most, all you need is a choice between normal drilling and hammer action, and variable speed (so if you only pull the trigger a little it goes slowly, pull it all the way in then it goes fast).

I bought my drill from Aldi, for about £15, but to be fair, they aren't sold there all the time.
so I'll say:

Cost £30 (total cost £93.50).

Drill bits
Once you've bought a drill you'll want a set of drill bits.
there is a difference between wood, metal and brick drill bits, but you should be able to find a set with an assortment of sizes (3mm = 10mm) and functions for around £20

http://www.diy.com/diy/jsp/bq/nav.jsp?action=detail&fh_secondid=11407674&fh_location=//catalog01/en_GB/categories%3C{9372015}/categories%3C{9372047}/categories%3C{9372200}/categories%3C{9392077}/specificationsProductType=accessory_sets/specificationsSpecificProductType=mixed_sets
that's a link for some wood, brick and metal bits for £10.

http://www.diy.com/diy/jsp/bq/nav.jsp?action=detail&fh_secondid=11537590&fh_location=//catalog01/en_GB/categories%3C{9372015}/categories%3C{9372047}/categories%3C{9372200}/categories%3C{9392077}/specificationsProductType=multi_purpose_drill_bits
that's a much bigger set for £35, and includes hole saws that let you cut out big holes in wood, you'll never find a 2" drill bit., but a 2" hole saw lets you cut a 2" hole which is useful of you're making a set of PC speakers or similar.

Cost £20 (total cost 113.50)

Screw Drivers
For electronics, you probably want a specialist miniature tool kit, (the screws on an iphone for example are PH00 whilst most mini screwdriver sets only go down to PH0.)
For wood working you'll want just a normal set of screw drivers, probably in the range on 3mm flat blade to 10mm flat blades, and the same with Philips head screw drivers too.

I'd recommend either buying a set of screw drivers, I got a set of 30 brand new from a carboot sale for £5 in a range of sizes and blade types (Flat, Philips, Torx), or you could go with a screw driver with changeable bits (so the same screw driver body is used).
You can get ratchet screw drivers (these can save a lot of wrist ache having to take the screw driver out of the screw head, line it up, insert the driver into the screw head turn and repeat.)

A ratchet screw driver with changeable heads costs around £12
http://www.diy.com/diy/jsp/bq/nav.jsp?action=detail&fh_secondid=9285164&fh_location=//catalog01/en_GB/categories%3C{9372015}/categories%3C{9372043}/categories%3C{9372176}/categories%3C{9392042}/specificationsProductType=sets

Cost £12 (total cost £125.50).

That's pretty much a basic tool kit right there, it'll let you tackle a variety of tasks from the big to the small, and can all be kept in a reasonably small tool box in a corner, or under the stairs.

I'd hoped to keep the costs as low as possible, and certainly buying tools second hand for yard sales or car boot sales can save a fortune. I do not recommend buying second hand chisels, or saws, or drill bits. They will already be blunt. and as I said earlier blunt tools are more dangerous than sharp tools, they also make a mess of your work.

On the subject of dangerous.
You can't do wrong with buying a set of "rigger" gloves (thick material gloves) to protect your hands, (from both your tools and splinters).
There are no loud tools listed here, but if you are using loud tools ear defenders are dirt cheap and you should use them, if you'll be creating dust, or working in a dusty environment a dust mask is a great idea, if you've got long hair then buy a hair band.

When using a chisel, you should only push the chisel away from you, never towards your body or towards your legs. Never balance work on your lap whilst trying to put screws into it (a screw driver to the groin is going to hurt!)
When planing wood (a plane wasn't listed) always plane away from yourself, Basically, the sharp end of the tool should always travel away from your body! the only exception to this is when using a spokeshave or draw knife, these are meant to be drawn towards you. (carefully!)

Probably the most important thing I can say is take your time.
If you rush things then you either ruin your work or ruin yourself, when I was younger, I thought I could cut through a piece of metal faster by just moving the saw faster, all that really happened is I ended up slipping and performing my own surgery on myself with a hack saw, exposing your bones isn't fun.

The Workbench/shop stock lists. Electronics (Beginners list)

I'm going to make a list of what I think the best starter work bench for electronics should contain. This list will be costed, -there's nothing worse than seeing a list of really useful tools then realising that you need to be a millionaire, (or be ninety and have been collecting tools your whole life) to have these things.

My "ethos" when making stuff is to make good stuff made well made cheaply.
by cheaply I don't necessarily mean that everything will cost pennies to make, indeed some things are very expensive to make -yet still cheaper than buying off the shelf. this applies to products and tools/equipment.

However, if I can buy off the shelf, and get a cheaper and better product than what I can make, then I'll probably buy off the shelf.


I'll be producing a few of these lists, because I don't think woodworking tools fit into the electronics tools list, nor do metal working tools, but if you are interested in making finished products, not just testing stuff out on a dev board, then you're going to need some tools and some skills to make a final project.

In accordance with an old hack a day post http://hackaday.com/2008/01/20/hackit-your-ultimate-hacking-workbench/ asking people to build up a work bench for $600 or less...

Well being as I'm from the UK, and that was from 2008. I'm going to say £600, (that allows me to not have to convert all the values, and allows for inflation). but I won't be spending all of that in this post. that's the complete bench costs, my bench needs tools for creating finished products. so I'll going to try and build the whole workshop for that price.

I'm also going to try to order the list in a getting your feet wet type arrangement, -so this will be the stuff that you might want to just pick up to be able to see if you even like making stuff for yourself.
so.... Here goes.

Electronics (Beginners list)
Multi-meter, -I don't recommend getting the cheapest, on the other hand I don't recommend getting the most expensive. (in the same way as my view on power tools went, professionals buy De Walt drills because the absolutely need them day in, day out), professionals by Fluke because they need them, day in, day out they are built to work in the shittiest of shit conditions, day in day out, they are drop proof, shock proof waterproof, dust proof and humidity proof.... my opinion is: "if you're a hobbyist, buy hobbyist tools".

For an absolute beginner, look for one that measures voltage, current and resistance. lots of meters will also have a transistor tester, and a continuity meter. More modern meters I've noticed recently, are including inductance, capacitance, temperature and even humidity and light meters as well as the standard volts/amps/resistance meters.

For the absolute beginner, ignore the fancy toys. buy basic, spend £10 - £20. if you need more functionality later then buy a bigger fancier meter later, you can keep your beginner meter laying around for emergencies, or when you want to work on the car and don't want your £200 meter getting dirty.

We'll call the price £20. (total so far £20).

Soldering Iron
I have a huge problem with people telling newcomers that they must get the latest greatest soldering station, with solder pots, and temperature control, and hot air reworking and all the other fancy gadgets. soldering stations of that calibre fall well into the professional end of the spectrum, and cost like they do as well.
http://www.rapidonline.com/Tools-Fasteners-Production-Equipment/Soldering-Equipment/Soldering-Stations/Weller-WSD81-80W-digital-temperature-controlled-soldering-station/300591 isn't that a lovely little soldering station? it's also £239.

Now how about this one? http://www.rapidonline.com/Tools-Fasteners-Production-Equipment/Soldering-Equipment/Soldering-Irons/Soldering-Iron-40W-230V/303066
40W iron, it's powerful enough to do pretty much all the work you'll want to do, and a mere £8.55
As a beginner, you need a around a 30w iron, (if you get a smaller one you spend too long trying to heat up the parts and just damage them, or don't get enough heat into them and end up with dry joints).
So 25w iron minimum, the rough price of this is £10 (total spend so far £30).
The 15W irons that get sold in some places are useless. In fact they are worse than useless.
The final thing to say it that as you;re doing electronics, not plumbing, get one with a fine tip.

Iron Stand
If you can, get a stand too, that stops you dropping your soldering iron on the kitchen counter.
http://www.rapidonline.com/Tools-Fasteners-Production-Equipment/Soldering-Equipment/Soldering-Irons/Draper-Soldering-Iron-Stand/311816

That stand holds the iron when you're not using it, and has a sponge for cleaning the tip of the iron, (a nice shiny tip to your soldering iron helps it transfer heat efficiently, and means that you don't have to hold the iron on the work longer than is necessary.
Cost £5 (total spend £35)

Bread board
Now, anyone familiar with electronics at all is probably thinking of the little boards with holes in, copper below that used for prototyping, but no, I'm still thinking about the solder stand and protecting tables, get a wooden breadboard. (your parents/significant other/house mates will thank you for the consideration). Any size will do, really, but somewhere between the paper sizes of A4 and A3 is probably ideal. and it doesn't have to be a breadboard, it could just be a bit of old counter top, or a piece of plywood bought new.

Cost £5 - 10 (total spend £45)


Solder sucker
http://www.rapidonline.com/Tools-Fasteners-Production-Equipment/Soldering-Equipment/Soldering-Irons/Draper-Solder-Sucker/311815

I prefer this to solder braid, but each to their own, the principal is simple, you're soldered something in the wrong place, so heat the solder so that it goes runny, then suck it up out the way.

Cost £5 (total spend £50).

That is, in theory enough to get you started.
You should be able to follow some simple schematics and make simple circuits.

though if you've just gotten £50 for your birthday, you may want to not spend all of that on equipment, as you'll want some money for components to get you started!

Though there are a few more things that you'll want to consider getting.

Breadboard

Breadboards are prototyping tools, they have standard spaced holes that are connected inside the board by wires that you can't see, they enable you to build simple circuits by poking the legs of components into holes on a board. these have a range of prices. starting at around £2 rising to around £10
http://www.rapidonline.com/Tools-Fasteners-Production-Equipment/PCB-Equipment/Prototyping-Boards/Protobloc-2-protyping-breadboard/29459/kw/breadboard
that one is a good beginner board (and when you buy multiple boards then can be joined).
it costs £5 (total cost £55).

Power supply
Aside from some little hand tools like screw drivers and a few components to get started, that is about it.
there is one very big thing missing however, a power supply.

Now I have to admit that I've gone a little all out on a power supply in the past and have one of these:
http://www.rapidonline.com/Electrical-Power/Power-Supplies/Bench-PSUs/Single-and-dual-power-supplies/65051
(the single supply one). 0-32v 2amp supply, digital readouts, super accurate, professional quality, but again a £250 professional price.

What's worse is that I hardly use the thing at all. Instead using my ATX conversion supply. A supply I converted myself from an ATX computer power supply. It has less range, but more usability due to it having split rails at common voltages.
Perhaps I should have gone for the bigger brother of the supply I did get and spent £320? but then I'd still only have two voltage rails.
Perhaps I should have just used my "free" (salvaged from an old PC) power supply, and not bought the supply I did at all.
Perhaps I should have just gone with a "wall wart" type supply. 3v - 15v, enough current for small circuits, cheap and available everywhere.

You decide what power supply you want. The general idea is...
digital circuits will tolerate some noise, as there are thresholds on the signals used. analogue circuits are more susceptible to noise. (hence you sometimes hear a hum on audio equipment) -that's mains hum, it's an AC waveform that's introduced on either the power signal or ground planes, and the fact that you can hear it means that it matters.

I'll post up some instructions on converting an ATX supply in the near future.

I'm therefore going to take an average power supply (wall wart) say that you'd cut the plug off and have a variable power supply for building/testing circuits.

If you look at this supply http://www.rapidonline.com/Electrical-Power/Power-Supplies/Bench-PSUs/3A-Switched-output-switch-mode-power-supply/65050 it's basically just a wall wart in a prettier case anyway.

cost £5 - 10 (depending on the current capabilities). (total cost £65)

So you've spent a little over half a ton so far, and you haven't really got a whole hill of beans to show for it (yet). -though you could get away with not having the iron stand, bread board (either the wooden type or the prototyping type). You may not need the power supply (use batteries? though these can be just as expensive). If you're building really really simple circuits you may not need the multimeter. In fact you can start making stuff with electronics without any of this stuff (I did when I was a child).

What you buy depends on what you need to do, if you only ever want to build test circuits, then the need for a soldering iron is small.
If you want to permanently keep everything that you make, you'll definitely need to solder it (else it'll fall apart).

In addition to this you're going to want some components. stuff like wire
http://www.rapidonline.com/Cables-Connectors/Equipment-Wire/Equipment-Wire/1-0.6mm-Single-core-equipment-wire-on-100m-reels/62317

LEDs, resistors, capacitors, transistors, op-amps... lots of components.

I'm not going to specify what you need, your projects will specify that for you.

Just know that you can start out with almost nothing, (a bit of wood, drawing pins, a paper clip, batteries and a light bulb) and still make something.

If you're just wondering about getting your feet wet or you've so far managed to make a torch, but really want to make just a little bit more, then I'd really recommend one of the 200-in-1 kits. these are a little pricey, (~£60). but as a thing for getting people into electronics they are really good, the projects in the book include making radio receivers, radio transmitters, lie detectors, amplifiers, light switches, light level meters, sound level meters.

Strangely, I don't think that I would recommend the 500-in-a kit. it's much more expensive (£150). the only additional benefit that it offers is a microprocessor (but a very odd one that I can't say I've seen used in many places, that's programmed in a peculiar way). For the same money you could get the 200 in one kit, and breadboards and such and get a more current microprocessor such as the Arduino, or a PIC set-up, with a programmer.

About and regarding tools and materials (ten tips.)

My tool collection is reasonably impressive. there is surely many hundreds of pounds, if not thousands.
It's not as complete as my fathers. that's for sure, (I'm missing a full sized pillar drill, bench grinder, lathe, table saw, table planing machine), but then I'm also clearly a few years behind him, and have time to keep collecting...

So here a few observations that I've made about tools and parts...

1, Tools are expensive, quality tools even more so. -but good tools, or good enough tools needn't be.
now I'm torn on this, for two reasons, I bought a B&Q value drill, it's ok, but it's not particularly strong (800w I think), it also has no speed control, so it's not particularly useful. It did only cost £10 though...
I've got a power craft drill, that's a little more powerful, with variable speed and only cost a little more something like £13 from ALDI.

does it hold up to a professional DeWALT drill, I doubt it.
will it stand up as well as a dewalt drill? I also doubt that.
will it last as long, probably not...

BUT, I can buy the £13 drill from ALDI 20 times over before I've spent as much as buying a single Dewalt drill, (which if I drop from a height would break just as easily!).
I'm already nearly 30, If my ALDI drill lasts 2 or three years, then I'll basically be able to keep buying cheap drills until I die, and still have spent less.

Basically, spend your cash wisely, sometimes the cheapest is not the best buy.
sometimes the most expensive, is not the best buy either.

2, Parts are expensive, but not if you know where to look.
do two searches now, open ebay and search 1hp motor on ebay, you'll see that 1/4 watt motors start at around £30, with up to £100 for a single phase 1hp electric motor...

now do another search, HP Watt conversion. you'll find 1hp = 746W.

now go read point 1 again, now point two... read until you notice that I can buy a drill that's got more than a 1ho motor in it for £10, or I can buy a 1/4hp motor for £30, a 1HP motor from £50 - £100.

the lesson here, sometimes cheap tools are good for a maker, they let you have a part that's cheaper than buying a retail.

if you buy the drill you get,
(a 3 pin plug) -retail £0.59
a length of flex -retail ~£1
a 3 jaw jacobs chuck searching ebay lists those as around £5.99
(so we're already over half the price of the thing!)
then you've got a motor. AND a small plastic gearbox.


3, Go into shops looking for tools, but don't necessarily buy tools.
Both ALDI and LIDL stock tools that are a decent price, and decent quality, their stock sale lasts about a week and you get a decent tool at a decent price (see the drill above).

When I bought the drill for example, I wasn't starting a project that required a drill, I just knew that in the future I would want a drill (that was better than my B&Q value one). so I bought it.

Next time I did a project that needed a drill ALDI weren't selling them any more. so I'd have had to go to B&Q or wickes and spend twice as much for the same quality drill.

Go into a hardware shop for a browse, you don't have to buy anything, and if you feel weird about doing that, choose little things, buy some carpenters pencils (for when you're working with wood), or a scribe (for when you're using metal), if you see a decent offer on a tool, buy it! even if you don't need it at the moment.

The same goes for tool boxes. I got a tool box with two draws and a space in the top for £20 from B&Q a couple of years ago, it was full of tools too (which did kind of upset the idea that I'd fill it with tools). it was on sale, and less than half the price of simillar tool boxes from the halfords next door.
I bought a rolling cabinet with a five draw box to go on top from LIDL for £60 (some £200 cheaper than similar set-ups in Halfords.


4, When you're in a hardware shop check the sales bins.
B&Q have little orange baskets that they fill with stock that's either end of line, or damaged packaging.
I've got tons of jig saw blades for less than half price before I looked in a bin.

Brazing rods in B&Q came down from £3 for a pack to £0.50 a pack, (so I took a lot, and a mixture of brass for working with steel, Aluminium for working with aluminium, and a different brass allow for working with copper). I've got something along the lines of 60 packs (I spent £30 on £180 worth of materials.

5, with some things there is no difference in quality
I have "value" tape measures, set squares steel rules, the value that they save is not in the size of the unit. my ruler isn't shorter because it was cheaper!

6, Go to Poundland, that's where I got my hack saw £4 saving on the B&Q value price, it's where I got a set of rasps from, it's where I got blades for my hacksaw, where I've bought vice grips from etc. It's your choice, you can go to a DIY store and buy five tools and spend £25, or go to Poundland, but five tools and spend £5...

7, Go to car boot sales, my router came from a car boot sale (it's a fairly decent black and decker one too) -from their pro range. it works perfectly.

I've gotten hammers, spanners and clamps from car boot sales, the price is pretty much always negotiable and if you don't think it's sufficiently lower than the price for buying it new, then walk away. go and buy it new.

If you're buying from car boot sales, do check that the things look like they'll work though, I bought a belt sander, electronically it works fine, but is missing the belt tensioner, so the belt just stops rotating when you try to sand anything. -if i'd opened my eyes and looked properly I'd have saved some money. (I'll strip it down and scavenge the motor, but it's hardly the point right!)

car boot sales and charity shops are good for fabrics if you're making anything with textiles, (as an example I bought a whole roll of flame resistant sofa covering, this will be the inside of a seat one day, and will also be the head liner on the roof of the car I'm restoring.

I bought a five draw A4 filing cabinet (the sort that do on top of desks and take paper laying flat the draws are about 1.5 inches tall) £5 or £10 from a car boot sale.
I have a much larger 15 draw one, given to me.
and found four sets of the same sort of filing cabinet (but with 3" draws) and six draws on gumtree to whoever could take them away.

so 8, look on gumtree. and free cycle.

I use these as a tool box, (a draw for metal tools, a draw for wood tools, a draw for screws, a draw for bolts, a draw for blades) (32 draws in total as I gave two of the 6 draw units to my dad),
they are not tool boxes, but they work well as tool boxes.

larger filing cabinets work well as power tool storage as you can stack quite a lot inside them.
steel cupboards make great component storage (you can put draw units inside and on the doors).

Don't be afraid to get things for free, something that cost you nothing is great.

Also don't be afraid of getting tools from ebay, (but don't expect to be able to return them!).


9, keep everything.
I might be a bit of a hoarder (in fact a selection of my stuff was once pictured in a PC magazine of what a person with too much stuffs house looks like!

but seriously, keep things that you think you have a use for.
just yesterday I was raiding my parts bit for screws from a computer case, without them at hand I'd have had to go to Maplins and buy some.

I just re-used some chromed steel rods (that strangely came from an old PC case), without them I'd have beeing buying steel from B&Q.

don't keep what you don't have to though.
as an example, when I built a tab welder, I was scrapping loads of PC's at work at the time, I took (de soldered) hundreds of capacitors from main boards, then threw the main boards away. I couldn't use the surface mount components. keeping 20 broken computers? that's have been silly, (even if I know that I'll probably want flat steel sheets in the future, and could have used the cases).

it's not going to hurt you to keep a stock of materials, but be realistic. in my latest project I've been working with aluminium, and saving as many of cuts as I can, simply because I want to do some casting (this is even on my to-do list). but don't save what you won't or can't use, don't keep what you can't store, and don't expand your store to the size of your house, because it's just messy, you'll end up dying alone amongst the piles of broken DVD burners that you were hoping to scavenge lasers from "one day"!
you can melt down milk bottles to make rep-rap materials, but don't keep endless supplies of old milk bottles, either melt them down or throw them away!

and number 10...
The most valuable tools that you have are your hands/eyes/ears/lungs protect them.
that means knowing how to use tools, keeping your fingers away from spinning blades, or behind the sharp point of a chisel.
and keeping your fingers from under the foot of a sewing machine.
holding work in a vice rather than in your hand and drilling into your hand.
if means after cutting metal, you should use a file to clean up the edges, don't leave them sharp, they will cut you!

It means tying back long hair. before going near spinning machinery.

That means ear defenders, dust masks, eye protection (either clear goggle or specific wavelength blocking with lasers, I reccommend auto darkening welding helmets, the ones from halfords are the cheapest ones I've found and they are good.

looking after yourself means wearing long sleeves whilst welding, (the uv from the arc burns you).

It means not drinking, or doing drugs and making stuff with dangerous tools. (the results are worse when you're wasted anyway. better to just enjoy being wasted and continue the making another day.

As you may have guessed I learned all these bits of advice the hard way, I did them wrong first. Sometimes hurting my hands, sometimes hurting my wallet.
