I've done a bit of research on VFD and it seems pretty straight forward. I had no idea how much control you can have over these 3 phase motors, and without spending a fortune. The old switches for the motor should cover the cost of a nice, like new VFD made in the US.
I have a couple leads on a replacement spindle and hopefully next week everything will fall in to place and I can put it all together.
One thing I really want to find is a production table with T slots. I would hate to put holes in this table but I don't see any other way to hold a vise.
