    I bought a Cincinnati #2 to support my horizontal mill habit. I would have relatively little use for it without many, many pounds of cutters to sharpen or modify. It does a decent job as a small,...

    Agree to look at bigger 4-slide machines if the job will fit in their capacity. Hard limits on cutoff length, pretty stern limits on forming pressures. Kinda/sorta don't agree on "black magic"....

    Does the internal threaded go all the way down to the cross hole? If so, I'd guess it's some form of electrical binding post for fastening wires.

    Other folks have already mentioned that smaller (e.g., under 3/4" diameter) locking ball joints are used a lot in photographic accessory mounts and also in professional audio mounts. One refinement...

    Yes, that was the intended use. More generally, for holding shafts on a mill.

    Does this chuck have a flat back? If so, you can probably turn your adapter plate into something like an Adjust-Tru backplate, using long setscrews to center the chuck before tightening it down. ...

    Much more colorful than Lincoln's 50lb square cans.

    Which actual variety of Eutectic brand rod did you get?

    For a 1/8" endmill, the circumference is 0.0327 feet. So a 6K RPM spindle will give you 196 SFM, while the 10K spindle will give you 327 SFM. The latter would be more effective with carbide...

    The opti-dress diamonds are usually lapped to a specific radius to match the stylus you're going to trace your form pattern with. Using one of those diamonds as a general purpose dresser would be a...

    Bobw, I acknowledge that you started that out with a Warning, but my immediate reaction is "Oh, FUCK No!". Please don't tell the infants to use thread gages as form taps on ceramic surface coatings,...

    So would this be mineral oil with 150 centiStokes viscosity? I don't read Japanese well enough to decipher why it's referring to both 32 cSt and 460 cST @ 40C in the Amazon product description.

    Then maybe it would ease your soul to know that manufacturers of milling cutters, and major makers of milling machines, both endorsed the practice well over 100 years ago. And as the laws of physics...

    You can probably adapt a tension/compression tap holder, usually used on mills without rigid tapping, for this purpose. It's exactly what they are for, and all you'd need to do is change the shank...

    Mal01 has it. Use a threaded flange or shoulder (which could be as simple as a pair of nuts) on the threaded mandrel. Back off the flange, then you can remove the part with your fingers. A full-on...

    Congratulations! Not being a silversmith or goldsmith, I had to look up "SNAG".

    Is that (Jim Wallace) your dad on the SNAG website?

    Ganged cutters is a classic. Old-school you'd use a fixture the length of your X travel with a quick clamping feature. Load up 15 or 30 parts, raise table, start spindle, cut in one pass, drop...
