    Can you give us a closeup of the working ends of the spindles? In that blurry phonecam image, it seems like one of them ends in either teeth or a crown gear. Is that accurate? Can we see it?

    I only have one data point. My Mitsui 6x18 (MSG-205MH) is a nice machine, despite years in the previous owner's shop mostly cutting off mold ejector pins. An instance in like-new condition would be...

    I'm not familiar with NozzleKleen #2. Were you using it to clean the ways prior to epoxy (degreaser), or to prevent epoxy squeezeout from sticking to the ways (release/no-stick)?

    Toward the end of the video, there was a pretty good section where you could see the cutterhead and workhead rotation together with a couple of tooth indexes.

    I like using a hard brayer, but the last Speedball I bought was atrocious. The axle pins were both way eccentric (1/8") and not in the same plane, so as you rolled the thing the handle went through...

    LPS-1 is an alternative to Starret M1.

    LPS-3 leaves a sturdy waxy coating. Not hard to clean off (like cosmoline) and easier to apply than anhydrous lanolin.

    In my opinion, the condition of the workhead will matter much more than any over-the-decades model changes. The one I think of as standard has NMTB50 on one face and MT5 on the other. If it doesn't...

    If those aren't what you are looking for, I can probably dig up some links to screwdriver-styled preset torque wrenches.

    Unless your customer's prints say otherwise, I would use tooling for the UN thread profile sized for 11TPI or 14TPI. The only thing special is that the size/pitch combination isn't standard. Thread...

    Pre-VFDs, the solution would have been a simple gearbox. If the VFD solution is working for you (i.e., not running into torque limitations), that's almost certainly the cheapest current solution.

    Yeah, you will not find it in any standard. That's sort of the point. It's a bastard thread that kinda/sorta fits, but it's probably out of spec (or at best right on the limit) for all standards.

    LOL. The only insert fatter than a W trigon would be an R round. No wonder you are having access problems.

    Look, you are not going to get satisfactory 40TPI threads from a 12TPI insert! The root radius of the 12TPI insert is practically 100% the size of the full 40TPI space. Imagine you had a perfectly...
