  • Copper Sheet From Copper Water Pipe

    Sometimes it's way easier to get hold of plumbing fittings to convert into sheet than to get actual sheet plus price difference can be minimal (although extra work involved. Several years ago I needed a solid copper ead gasket for single cylinder motorcycle. Used a 4-1/2" coupler split and flattened. as it was cheaper than buying 0.050" thick piece of sheet at the time. Used exact same method to anneal though

    Tin Can Hole Saw

    'ordinary' can is thin and soft enough to cut with kitchen scissors. I like the idea of case hardening using graphite powder and transformers though, I've only ever used flame or furnace with 'Casenite' case hardening compound. For a one time use cutter for softer material it could be an interesting experiment

  • How to Sharpen Used and Dull Drill Bits (By Hand!!)

    I was taught in mid 70's to use drill flute to get 'correct' rotation. Seen way too many 'sharp' drills done with 'your' method that have rear edge higher than 'cutting' edge. If it works for you, great but there are multiple methods for getting good cutting edge. If you have two equal spirals coming off work, you know it's (probably?) right

    The main reason not to wear gloves while sharprning 'anything' is to be able to feel temperature. If it's getting hot, it's too hot

    If bit changes colour you got it way too hot. The sparks will be red hot but I've only ever seen small (1/8"~3mm) get red at tip when re-shaping broken bits. Getting a 1/2" to 1-1/2" drill cutting edge red takes more power than average bench grinder can supply

  • Building a Computer Desk / DIY Desk PC

    LOL, yep, I 'designed' mine around 1999 and built most of it in 2001. Unfortunately, I built it in the room I was going to use it in and it got put into service before being finished as I was working 12+hr shifts for over 3 yrs. So far, 16 yrs later, it still isn't finished but has been 'upgraded' over the years. It's one good thing about having a LOT of space for components

  • How to Sharpen Used and Dull Drill Bits (By Hand!!)

    I've seen people try that (and other drill 'tricks') never seen drill bit actually work on anything other than softwoods afterwards though

    material 'softening' or over hardening edge is only a problem when you have carbon steel drills, maybe woodworking stuff? HSS 'should' be able to stand red heat and still cut (depending on Vanadium, nickel, chrome, cobalt, etc. composition) It's more likely that edge will get overheated then 'quenching' may cause micro-cracks in edge. I believe micro-cracks, chipped edges and weird sized holes was only an 'industry' issue in the 70's~80's though?

    We had one in woodwork class, but that was early 70's LOL

    Very good 'ible', don't remember last time (if ever?) I ever made so many comments to replies. For anyone 'complaining' about 60 degree angle, use a pair of hex nuts with flats together to get a 120 degree 'gauge'. I was taught that 'trick around 1974. Instructor told us, a sharp 120 is way better than a blunt 'correct angle'

    That's a really good looking piece of furniture. I don't have a planer of joiner though (or anywhere to put them if I could afford them) I guess 'garage quality' workbenches would be a good practice for anyone wanting to try this without 'equipment'?

    I would think the 'weakest' point would be the rear upright as it's being 'bent' in the middle from the braces? Even so, pretty sure it would take 1/2 ton or more on the front edge to actually damage things? (I'm not an engineer but I have worked on 'stuff' for 48+ yrs)

    I think a couple of people missed the point. As far as I can tell the main expense was the black paint? Everything else recycled so I guess main reason for Instructable is to show what can be done without spending ton of cash? You also get some practical stuff out of it. From experience I can tell you, using a 'step drill' (the 'Christmas tree' shaped cutters) makes drilling very thin material much easier than a regular drill and for aluminium cans, the cheapest one you can get hold of will work fine.

    This is a pretty educational Instructable.I've had the PA20 style since around 1980 and IWISS style for several years and done literally thousands of crimps on 1/4"~6.3mm spade terminals using 14 ~18 gauge wire without a problem, the IWISS style being slightly quicker to use. Because I'd had pretty good results I got the smaller IWISS style. I found the same as you, the dies seem to be the wrong size and impossible to get a good crimp.I'll try adjusting them as I kinda like the way they work, holding terminals better with the locking ratchet compared to PA20 style

  • Refurbish Your Old Rims - Make Them Look Like New!

    Looks good, I do a bit of aluminium polishing on motorcycle parts plus I've done quite a few alloy wheels over the years. It's a ton of work to refurb wheels plus keep them good afterwards. Very few paints will 'stick' to aluminium for any length of time, the oxidised surface prevents good adhesion, particularly when highly polished. Aluminium forms a surface layer of oxides a few microns thick almost immediately on exposure to air, (but, you know that) Professional polishing will leave a layer of very hard wax which will protect wheels for several months in good conditions but only a few days on 'salted' roads. I'm British, the dally/weekly freeze/thaw cycles mess things up quick as there is a lot of salt and water

    I think a couple of 'armchair mechanics' are way overthinking things. (British definition 'Jobsworth') A working light will ALWAYS be superior to a non-working light. As a kit for repairing , probably illegal if it doesn't conform to all specs. As a repair, it's fine if it doesn't conform to all specs, I don't think any police are allowed to dismantle vehicle to check for conformity (maybe in Japan or German TUV testing station?) I know in Britain, the vehicle inspections don't allow tester to dismantle things to check suitability. All in all, I think it's a real good Instructable, not only from safety point but also aesthetics, 'broken' high level lights just look bad when only a few places light up

Higher voltage is required for lean mixtures and the opposite for rich mixtures,the reverse EMF from ignition coil changing to match. Reverse EMF induces up to 350v in primary circuit

Used an old fan from Suzuki 80cc ATV as spinner with almost everything machined off to give it some texture and interest. 10mm stainless steel Allen bolt plus a wingnut to give him something else to fidget with. I should have paid more attention while polishing, even after removing almost all the fan blade plus rounding off, spinning at 10,000rpm (or more?)

  • Make Sliding Barn Doors Using Skateboard Wheels

    I was wondering what holds the wheel in position on top of track? Are you using some 'T' nuts inside the track section or is the bent edge of roller holder fitted behind track?As for the other 'argument', if door weight was found to be an issue, it would be even simpler to get some ordinary round steel (or aluminium) bar and cut 'wheels' from it. If obtained from a machine shop, a flange could be turned (or added) to rear edge to hold wheel in position over track. As it is, it's a real simple , cheap way to make barn doors. If you watch some of the home shows on TV interior 'barn doors' are now a 'design' feature in homes. I'm sure skateboard wheels would be a quieter option than the standard cast iron wheels and track?

    The vast majority of pistons are cast as it's much cheaper than specialist alloys used in forged pistons. Cast pistons are generally harder wearing with lower expansion than forged pistons. (but somewhat brittle, they crack or break rather than 'bending'). Hyperutectic pistons are cast at higher temperature with added materials (silicon, etc)

Just because it's small and cheap doesn't mean it can't be used for precision work, you just have to know it's limitations and take more time setting things up.It isn't a production saw by any means, but, 'we' (the people using it) are not production woodworkers

    Tune Up Your Table Saw With a 2x4

    That's a great 'structable' not using any expensive equipment means anyone can check and adjust their table saw. I'm going to check mine as soon as I finish some unrelated projects

    Electromagnetic Sensor

    Could this be used to find nails or metal in wood? An electromagnetic 'nailfinder' is expensive for the amount of use it will get but this would be real handy for 'pallet wood' builders

    Chuck Box - Camp Kitchen

    Pretty cool your still monitoring build (even if it did take a while to get back to people ;) )I've been 'designing' a fold up case for electronic/electrical stuff along similar lines to have everything in one place with a minimum footprint yet still be transportable. I think I'm going to re-design now so I can fit a 400w inverter for solder station or power supply and have an 'on site' electronics workstation with no need to run extension cords or start up generator

  • How to make a reliable motorcycle voltage regulator

    Good Instructable but only applicable to permanent magnet alternators. (PMS )Electromagnetic alternators where field coil needs a monitored voltage to provide magnetism needs extra circuitry (EMS) It's always a good idea to have airflow to heat sink should stay nice and cool back there but may get 'attacked' by chain guard at full bump?
