    On my NOGA MiniCool and a local highschool's FogBuster, I use KoolMist77 1 part to about 20 parts water. I think a "heavy" mix for KM77 is 1:10. Unlike "soluble oil" emulsions, this does not...

    I would strongly advise against this. Tooling is still available on the used market, but there's basically zero support (and close to zero community knowledge) and zero repair parts for the...

    Some variants of polyimide will have thermal expansion that low, but you'll have to read spec sheets.

    Many species of wood also meet the spec, but you probably want something homogenous and...

    I had a similar experience back in the early '90s. I had sent an MT3 reamer out for resharpening, and when I got it back, it would not cut. I had to send it back to the sharpeners (no charge) and...

    Other thing is, you don't need a perfectly gouge-less bore. If there are no high spots, and the ungouged portion of the surface makes good contact, that's going to work just fine for a tailstock. ...

    What's the included angle between the flanks of the threads?
    What the lead (pitch) between successive turns of the threads?

    With that info, we might have a faint prayer of identifying the thread...

    TGraves3, do you just need a shoulder 12" below surface level? If so, consider a through hole/bore with a groove at the right place for a suitably stout retaining ring. I like Smalley spiral rings...

    I don't recognize the machine specifically, but it might be some type of double-ended boring or planetary mill for machining the ends of axles or other shafts. You'd mount the axle on the table and...

    From the photo lighting, I can't tell if that's a ridge or a trench. You said "groove", so presumably a trench.

    No, that's not a style I'm familiar with. Does the body of the bar have any...

    Right. Those are from OK. I don't know what, if anything, OK might stand for. People familiar with them are likely to refer to them just as "OK".

    You probably do have a bad batch. That is completely unlike how Canode behaves for me. I get a transparent film and have never experienced a chalky consistency.

    Are these parts going to be bolted to something else? Welded? In either case, being very fussy about "free air" parallelism is not productive, because they are...

    Slit pump tip does not work for me on 3/4 of my lathe's oilers. It should, so I conclude there's something badly wrong with the oilers or their installation (like they're sitting in blind...
