    I don't think it would be difficult to retrofit such a device (I have a few ideas in mind) but like others have noted I question the necessity of it. A simple logarithmic pot under the compound could...

    Nice work! I have to confess having a soft spot for the 10-turn precision pots with the mechanical counting dials. Used to have a box full of them from scrapped equipment yrs ago. I can easily see...

    Actually I would want it on a lathe more than a mill. I ran a Haas CNC lathe for a while and it was so cool because they can set the perfect RPM automatically for the diameter based on where the tool...

    Wow that looks like a sweet setup! Have to confess the variable speed would have discouraged me from trying it, maybe with a Reeve's drive instead....

    Been using my great grandma's 12" Griswold skillet for my entire life. Wouldn't have it any other way -- very smooth and controllable. Cleanup isn't too bad either. FWIW, I prefer to cook with gas.

    You'd be amazed how well they do with an LED bulb. I simply retrofitted all my old flashlights with them. No goddamn "flash" settings, just "on " and "off". And they have the switch where it should...

    Well, I think your actual forces will be considerably higher due to using screw motions to move the table etc. Your overall play is going to be more than the deflection simply due to the fact that...

    X3. Loosen the bolt on top of the tool post. Push down on the rear of the tool holder so that the tool tip goes up. Then tighten the bolt on top again.

    I setup my tool post so the flat side is dead nuts parallel and square with one side of the compound. Just using a straight edge, a ruler is good enough. Then I use angle gauge blocks to measure off...
