    This dawned on me on the way to get something to eat (which I'm eating as I type). I assume a VFD can't instantly switch two legs of the 3 phase like a Bridgeport switch. It has to go through the...

    When you set a VFD to stop faster than it's capable of without a external resistor, it shuts down to protect itself from overheating and coast to a stop. My Lagun 3HP mill with Reeves drive has a lot...

    They currently have 446 listing and have sold 16 listings in the last 60 days. That's a terrible return on the time and effort invested. Hopefully they're better at the rigging business than they are...

    Brandon said it's for a customer.

    Brandon, why not make them like the originals? They look nice and are balanced. Or maybe not, and that's why you're building new ones?

    I had to make 3 or 4 cuts in 1/2" X 10" 6061 flat bar. My son appropriated my good circular saw, so I used a cheap Harbor Freight 7" circular saw...
