I have good results with end mills. The ends are easy. The flutes are another thing. Hard to get a smooth run
with the setup I am using with the spin indexer. Results are acceptable for home shop but an air bearing would be better.
Put the new motor on today and what a difference. Both were rated at 1/3 hp but the first one (gray) was less than 1/4 hp. I tried a bit of surface grinding on an old rail road track cut off that I use for an anvil. Worked pretty fair. Not as smooth as I would have liked but it is flat. I will mainly be using it for flats on shafts or putting a flat on a cylinder etc. Should be useful for grinding any hard steel tools or parts.
Still need to retry lathe tool bits with the new motor. Can't wait.
Have a couple of end mills that could use some sharpening too.
The new motor mount moves the motor back 1" and allows more tilt. Up to 20 degrees up or down.
One need is a fine feed on the carriage. The 1/2-10 lead screw is much too coarse. I will add a fine feed in addition to the lead screw since I want to keep the fast speed to raise and lower the motor during any major setup changes.
A few pics of the new motor and mount:
