    I prefer to use ordinary hand soap, it seems easier to heat from the back until soap goes dark brown, to black you can even use kitchen stove to do it that way. little more clean up but easier than using Oxy/DA or propane torch. All you need are pliers and a bit of care

  • How to Make a Reliable Motorcycle Voltage Regulator

    On any Honda motorcycle, plain black wire is always switched power (battery voltage) When it's on R/R, its the signal voltage to tell R/R battery needs charging (or is overcharging)

    I think you need to re-check your rectifier connections and make sure you don't have something in backwards or an input connected to an AC? Did you check alternator output voltage? (AC volts) I would expect 40~60VAC @2,000rpm. I've seen a Honda C90 put out almost 100 volts AC, (no load) at max rpm (on a 6v circuit). Customer complaint was 'it's blowing bulbs'

  • The 'correct' Way to Measure a Cylinder Bore and Measure Cylinder Using Piston Diameter

    Hummm.... That IS a two stroke cylinder. The process is exactly the same for two or four stroke but four stroke cylinders are easier as you don't have ports. Designing two stroke expansion chambers Is relatively easy, but, you need to make several for testing plus, correctly done it will amplify exhaust note so silencing becomes difficult without destroying the power you've obtained. At one time, several (most?) manufactures actually provided information on building tuned pipes (at least I know Kawasaki and Suzuki did) In the service manual for T305 there is a diagram of pipe.A lot depends on the engine your building for and the type of use. No point having a 500rpm power band on an MX bike as it would be almost unrideable but on a drag bike it's all you need

    Just realised what your asking (was in a rush this morning) You want set up with degree wheel to measure port opening and closing points, simple enough, just fit degree wheel to crank end and set to TDC=zero. You can also do it by measuring cylinder then use trigonometry but that is way more difficult as you need to take con-rod length and angle into account.

    Table Saw Jointer

    This will work even on a cheap 'contractor' type saw. Even if blade can't be set exactly 90 degrees, (I haven't 'got inside' my HF saw yet) flip board and angles will match perfectly. Makes glue up slightly more difficult but I already figured out clamping boards flat.

    Oh, forgot to mention, the blade that came with saw is actually very good, I've taken a 3/16" cut down side of 'pallet wood' boards an gotten a 1/16" 'veneer' with a smooth surface finish, better than some planers or joiners as multi tooth blade taking a tiny cut doesn't set up same type of vibration compared to knives on a 3" circle

    Because I trained as a precision machinist I have various 123 blocks, parallels, etc so I use them in combination to get blade and fence parallel. Probably overkill setting to 0.001" but I find it quick and easy

  • Tubing Roller-Bender From Scratch

    Generally, no. your better off bending then 'barrel' plating a batchChrome plating will probably flake off on inside of bend and crack on outside radius Chrome doesn't like being compressed or stretched

    Is aluminium robust enough for the dies? 7075 is harder than 6061 but unless hard anodized will still be pretty softI would think they will wear very quickly and have a series of flats if used with steel tube?

    It's a lot easier to get a hole saw to cut aluminium if you have a couple of 3mm~1/8" holes drilled all the way through. After first 'marking' cut is made you have layout for circle use it to line up small drill. I've found belts slip on most drill presses using hole saw on even 1/4" plate plus, the hole saw can bind as things heat up.

  • Cheap DADO Stack That Works and Is 'realitively' Safe for a Cheap Table Saw

    Yep, when an idea's time has come it will happen. It's not the first time I've heard this, about 25~30 yrs ago I 'invented' a 'pulley' to reduce friction on bicycle dérailleur gear change, less than a month later a 'commercial' version was being previewed in cycling magazines. Wasn't as 'good' as mine tough as it was only available in a 90 degree 'bend' I made various angles as POC but 90 and 120 were the only ones I used. They worked really well (and still do when cleaned and lubed) but as there was already something on the market I never went any further with idea

    I'll have to check out the Freud spacers. CD's are a bad idea as they are polycarbonate and will allow 'slippage' plus need to be 'crazy tight' but for relatively shallow slots can work. Using 24t blades means you could have a minimal overlap to prevent 'corrugations' at base of cut but as you found out, sharp chisel works fine.

  • The 'correct' Way to Measure a Cylinder Bore and Measure Cylinder Using Piston Diameter

    Hi, The AMMCO sets I have do give some idea of stone selection and speed/rpm for different sizes but doubtful the cheaper sets give enough advice?What are you trying to do? If you want to get cylinders to first oversize for new pistons it's best to start with a coarse grit stone, 80~100 if available. Hone to within 0.002" then switch to a 240 or 280 grit. You can either buy a 320~400 grit 'FlexHone' or use 400~600 grit for finishing, if your building a semi race motor or turbo/supercharged I would use 600 grit rigid hone as it will give a finer smoother surface but takes MUCH longer than the 'production' machine shops methods which is why it isn't used very often nowadays.

  • 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

  • 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'

  • 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

  • Car Brake Light Repair (LED Conversion)

    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

    That's a clever idea, I have same bookends which are just for functional use and could easily be 'blinged up'

  • How to Make Custom and Strong Tank Tracks for Very Cheap.

    I guess I'm not very good at searching and found this by accident. Even though it's 7 yrs old now it's still a great Instructable, probably better than poster originally realised? Using tube to fit into curve of chain side plate will prevent it twisting ('racking') to a greater degree. As for drive cog, dismantle a free-wheel/gear assembly, usually plenty scrap at cycle shops they may just give you 2 (one for each track) Majority of cycling enthusiasts only use a few of the 6,7,8,9,10,11 gears but you need 'matched pairs (unless you only want to go in circles)

  • Organize Your Shop With French Cleat Tool Storage

    Isn't solid wood stronger than plywood? If the 'sharp' edge is rounded over slightly it won't get broken off, I would expect the outer layer of ply to 'come loose' over time?

    Hinge Mount Tear Out Repair

    I'll vote for it as it's a repair, not making something new with something old or re-purposing something but an actual fix for something broken
