    If I were going to make a centering plug for locating the table center, I would first check the larger diameter above the thread, and see whether that is accurate/concentric to the table rotation,...

    Optical tooling such as you mention is one group of items in "the toolbox" that I sometimes use for opto-mechanical purposes. What is your intent and/or application? Inquiring minds would like to...

    The bigger and more expensive the boat, the bigger the ego, in my estimation. You basically have to weigh whether any amount is worth the potential aggravation, then make that decision for yourself....

    Spoke with Barry at H&W, and he said to just tap the gear in lightly with hammer and appropriate hollow block. As I surmised, the top of the worm wheel teeth are...

    If you have a lathe chuck with 2-piece jaws, you can buy some soft jaws to fit your chuck and then add some mounting holes to those jaws to accommodate the jaws that you want to use. Or, if you have...

    For that thickness, I would most likely use the tablesaw, with a triple-chip carbide blade like others have mentioned. Unless you have good clamping of the sheet stock on the shear, it will perform...

    I assume that the mechanism is similar to a standard BP quill, where there is a small hook on the quill pinion shaft that captures the end of the spring. That is what is keeping you from pulling the...

    I'll step out on a limb here, and speculate that the thread is quite possibly 1-1/4 x 8, rather than 1-7/32 x 8. I would check the spindle thread with thread wires to confirm its actual pitch...
