This is the little servo I have been playing with to teach myself a bit more tuning.

Here is a picture of the following error just goofing around.

This would work great for a mini/micro mill - Tempted to buy one for home.
Now I finally got a decent read on the large servos votage/rpm=.125
So at 150v = 1200rpm <- which is its maximum rating. That would give us a max speed of 200ipm with 2:1 and 3tpi.. (we where going to direct drive it but for ease of retro we are going to belt drive it.) Plus the 150v falls right into the operating range of the diy h-bridge.
