    Might see if you have a local historical society that would like to document it. Don't know if schools even have photography clubs and such anymore, but back when they did, documenting something...

    Very cool! I live in Canandaigua, or at least just a couple miles out of town.

    IMO, the above drill, glue dowel method will be closest to originality, especially if you match the wood. I'd probably make a threaded brass insert with as thin a wall as possible, rough it up or...
  4. I know nothing of SB details, but having a feed...

    I know nothing of SB details, but having a feed hole to an undrilled Oilite bushing works fine. The light oil diffuses through the bearing as needed. Is the bushing Oilite?

    Don't forget the whole rest of the shop. A CNC mill needs support plus there will be other things you need to make for prototypes. You need some kind of lathe. You need some way to deal with stock,...

    Search here on how to make a tap. It's surprisingly easy and I've done it successfully several times.
    (edit) Hell, everybody's too lazy to search, so here's a link- Making taps
  7. I don't know about lifetime, but I pull my lathe...

    I don't know about lifetime, but I pull my lathe spindle apart every decade or so to clean and regrease the bearings. OTOH, the HLV-H at work has probably never had the bearings touched in its entire...

    IMO, you'd be far ahead to hire somebody who does this to do it. What you've described is way beyond what you can probably learn in any reasonable amount of time and the cost of mistakes in terms of...

    I think mine is a 57 and the motor is loud as hell. It has an internal fan and external air filter because it moves so much air through the windings. Probably gets warm but I doubt it could get hot...

    I do that sort of thing with a spreadsheet, one that grows more tabs every year! I don't like on-line tools that may or may not be there next week and aren't usually quite right for what I want to do.

    I don't think seeded gel wheels are a good choice for small grinders or soft steels. Mine have been expensive and disappointing, though they work well enough on hardened steels. Go with the white...

    No experience here, but it seems to be a lithium grease with EP additives. IMO, that would be most lithium greases. Can't find a number on it like #1 or #2, but the stuff is widely available for...

    I remember there are some slight differences between manufacturer's supposedly standard spindle threads. This may help- Spindle Data Summary

    A Sherline is slow and a pain in the butt for anybody used to a SB or Logan. It's good for light cuts only, but you can machine steel. Threading is annoying, but in spite of all that, it will hold...

    Let's assume they invented a thread. The problem here is vision. You need a low power microscope or loupe that works hands-free. Then you can use pitch gages or cut some triangles out of whatever and...

    One more thing- my grinder only works well when all four feet are in firm contact with the floor. Not only should it be level, but the load should be shared equally between the feet. When mine...

    Turning small shafts with a high L/D ratio doesn't have much to do with the lathe, which can be a piece of junk. The reason is that a moderately sane person would use a box tool of some sort, putting...

    Well, all of the above. I'd never grind a chuck until I knew the grinder was working perfectly. And you don't want to grind out damage as that would mean grinding way too deep, just get the surface...
  21. I do most of my small parts at low speeds,...

    I do most of my small parts at low speeds, usually about 700 rpm. Too lazy to change the belt to the other motor pulley. It's no problem, but I think I'd find 500 just a bit low. That said, if you...

    This must depend on where you live and power dependability history. I don't normally lose power during a storm, but experience fairly frequent power outages for no good reason at all. They usually...

    It would be easier if you could cut it up into smaller pieces, but the total price might be the same because you'd have more of 'em. :D
