    That sounds like a really bad idea. Acme taps are fragile. Maybe there's somebody braver and with more experience that will say go for it, but not me. By hand. Carefully and with decent veggie or...

    The original post referred to patents and a signed and dated lab notebook trumps most else. Even if somebody steals your files, and modifies them, you have proof of what you came up with and when.

    Definitely paper for me and it's important to sign and date everything, ideally in a bound lab notebook. IMO, CAD won't be really great until we can do it by voice like Tony Stark did it in whatever...

    It's true that light paint absorbs less than dark paint, but the difference is less than you might think. They both absorb quite a lot of IR in spite of the visible difference. I don't have a good...

    Living in upstate NY, I'm curious about winter battery life too. Teslas are multiplying like rabbits around here. It's become a subconscious game to count them as I drive the 20 miles to and from...

    One could grind it or fly cut it, but being thin it will still likely have a bit of warp. Can you just shim the runners to put them in the same plane?

    I want my wheels tight, but not crazy tight. FWIW, if you use a VFD, the speed ramps up and down, so nothing ever spins on start-up, but you still don't want it to shift while grinding!

    That Amazon one is M26x1.5- there's a print in the images. The Sopko is a bit of a mystery but I think it's 0.975" x 16 tpi, at least that's what the one on my Boyer Schultz is. My puller is snug at...

    I love grinders but the capabilities of good CNC machines have reduced the need in general and nobody wants to pay for grinding. Fix yours or get a better lathe.

    I made my own wrench; block of aluminum with a couple holes for dowel pins and milled clearance for the middle of the hub. Someday I'll screw a handle to the side.

    I've had good luck with these on my Boyar-Schultz- Amazon.com: HHIP 2420-0320 F320 Grinding Wheel Adapter: Industrial & Scientific

    Note that the removal threads are a bit different and you should...

    I think some phenolics will do that. Or, maybe something from Aremco?

    I've seen the seal-against-a-chamfer design and it has its place, but it a PITA to get right every time. You people really don't have much imagination when it comes to profits. Never argue with the...

    Superlube oils are PAO and contain no silicone, except for the ones they specifically say are silicone, like their silicone o-ring lubricant. No idea about auto-ignition but it was a big topic for...

    IMO, maybe a Myford is a good choice, then get a good pocket calculator app for his phone. Stick a piece of tape on it and write "25.4".

    Maybe a Logan 10"? Scott Logan can still supply parts. Lathes.uk says about 435 lbs for a bench model. Ball bearing so can turn faster than a SB, though IMO it doesn't make that much difference. Just...

    IMO, if you're unhappy with epoxies on suitable substrates, it's not the epoxy but the preparation. I find most of the advice, even from the manufacturers, is either impractical (dichromate and...

    Fix the wonky bits and a little cleanup and that will be a very serviceable lathe. I think the apron is better than the 200.

    Cold? FTLOG why? If there's some volume I wonder if an induction heater could quickly get the area up to temp?

    I have to wonder what would happen if we needed to make a large number of tanks and warships ASAP.

    1/8" mild steel brackets? No, I think that's way too thick.

    I used one like the Grizzly some years ago and on the plus side, it was super handy for brackets and such. On the minus side, it's of the quality you'd expect for the price. Expect to disassemble it...

    The hone needs some TLC but I notice it has a Sunnen bore gage on it. Those can get a good buck, but they may not like outdoor storage. Honing tooling is easy to sell if it's not worn out. Much of...
