    ID A vise screw, and help making an Acme Nut

    Here is another way to make the nut. Weld your blank up out of whatever pieces will make the shape, but with a tube for the nut portion, ID just a little bigger than the screw O.D. Coil a wire or piece of slender keystock to fit nicely in the trough of the male thread. Fit it into the tube...

    ID A vise screw, and help making an Acme Nut

    I made a vise nut once by molding a pattern with my hands out of warm wax, to fit the dovetail in the vise body, and squeezed into the threads. I dipped the dovetail in more molten wax to fatten it up a bit so I could file it to a drive fit in the body. Unscrewed the wax nut from the screw...

    Gimp needs advice buying lathe

    Calling myself a gimp will be S.O.P., if I live long enough to achieve the honor. It says, "I have nothing to feel ashamed or embarrassed about, and I call a spade a spade. (not a pine-handled backhoe). When I become a gimp, one of my first projects will be to build myself a wheelchair...

    OT - Old belt driven diesel generator for home backup?

    I have a 3KW Wisconsin-powered genset that is self-regulated I think that means it has a compensating winding that opposes the field is voltage gets too high. But a genny with a separate exciter probably needs a regulator. The rheostat may be for setting the voltage on the (missing)...

    recycle T&G flooring??

    Thanks for the sage and kind advice! The denailing will be the most laborious part, cut nails but not too many of them. The ripping to remove T&G I am comfortable with...the T&G ends I will leave. Whether I actually attempt this will depend largely on whether the little nameless green Chinese...

    conductive lubricants

    In my experience many electrical connections benefit from some kind of "goop", to retard oxidation, exclude water, prevent corrosion, lubricate, and make future disassembly easier, I know there is a standard product used on aluminum connections, but I do not know how suitable it would be on...

    Could your shop make artillery rounds?

    On a less-political note, I saw a piece of news claiming that NATO is buying 220,000 155mm rounds for $1,200,000,000. My arithmetic says that is about $6,000 per shot. Is that for real? What is so expensive in a 155mm artillery round ?

    Moving out the Boxcar Machine Shop, Approximate date of Brown & Sharpe magnetic chuck

    I hope we technology dinosaurs are more successful at avoiding extinction than the reptilian kind were. What we know is the culmination of ten thousand r more years of learning, and its "irrelevance" to today's electronic world is a vicious delusion: our "black start" technological history is...

    OT: Automotive Gaskets Corrosion and Silicone Grease

    Any kind of grease sounds to me like a leak-path. If you have corrosion pits or the sealing surface is wasted so it is no longer flat, then adding a sealant that cures, like silicone , may help.

    problem with a drill/tap for non common thread

    I am confused because i am pretty sure that the thread for a Schraeder valve stem is .305-32. I have made chucks for them. I do not know what thread is used for the Presta valve., or for the female thread into which the core screws in either Schraeder or Presta valves.

    0t--wire rope suspension

    I taught myself to short-splice 3-lay rope back in the early 1980s, while waiting interminably to pay for my loot after a poorly-run machinery auction. At the time I would often make back the money I spent at auctions by helping other buyers load their purchases, with the boom and hand-cranked...
