    Not sure this is really a good idea but none of those relays are critical to the lathe function and all can be bypassed while you're looking for replacements. The timer is to keep you from starting...

    269569I went with 4140 since I kind of know it. Since I don't know the material state I'm thinking my process will be to rough machine it leaving most everything .010 over, send it out for vacuum...

    That's what I'd do. If you really want it machined I could do it but you'd have to pay shipping to NM and back.

    Likely not reaching the folks who'd be looking for it. Try a wider ranging format - eBay, machinetools.com, etc.

    Collet chuck body material

    I'm making a new body for an existing collet chuck, a Pratt Burnerd LC-15. I never was able to find a chuck with a D1-3 back and finally found a really good deal on one with a different back. So...

    IIRC every .001 you ream from the MT2 takes .007 from the length. So if there's some pit you ream out completely you might set the gage line back enough that some shanks hit the stop pins.

    You'll want to use a bore gage on the tailstock casting and see if the wear is to the quill or the tail stock casting. If it is the casting you can likely have it honed cylindrical and make a quill....

    I recall that Victor Machinery has the tap. If I recall the Lufkin, Starrett, Central and Mitutoyo inside mic heads all use that size.

    Also, there are some 5/16-56 heads from Tumico - I grabbed a...

    If you look closely at my wrench you'll see a flat beat into the back of it. The PDQ VS taper needs a little love tap to break it loose from the holder.

    I think it's a standard hook wrench (McMaster McMaster-Carr ). If you want/need more toolholders PM me, I've got a fair number spare.

    I'm pretty sure that it's a 608, so a 608-2RS would be preferred (or a 608ZZ, they're kind of protected so a shield should be ok).

    Easy way to check would be to drop one of the read gib blocks and...

    Does your leadscrew indicator mount to the helix angle of the leadscrew? If not you won't want plain sput gears but instead gears cut to the leadscrew's helix and the screw's pitch.

    I'd bet that was a hit from something else - a face plant always breaks the carriage feed wheel first. With an intact carriage feed wheel there not a lot of ways to take out the cross feed.

    Looking for 3/4-12 spade head screw

    Think of an overgrown thumb screw and you're in the ballpark. I can't find any of these myself but I thought I'd ask here before I make one. I need one 3/4-12 (yup, 12) and 5 5/8 OAL or better -...
