I have a 7.5 HP electric motor, with what looks like a 1 3/8" shaft
(213T frame). I will use it as an extra idler on my phase converter,
to be spun up when the main idler starts.

I would like to cut the visible part of the shaft off completely.
Cutting the shaft off would allow me to put the motor into any corner
of my garage without any enclosure, without worrying about things
wrapping around the shaft etc.

The question is how to cut off the shaft. A couple of possibilities
come to mind, one is to spin up the motor and use a hacksaw, another
is to use a angle grinder. The first seems more fun but also more
dangerous (hacksaw getting caught up in a powerful motor), the second
is less fun and may not get a cutoff as clean, leading to vibration.

If you're going to be making stuff out of steel, you will find this
extremely useful. I have a Milwaukee, but Jeff W. sez this HF saw
works great for him == for about 1/5 the price of a Milwaukee.

This would cut your 1-3/8" shaft in about 30 seconds. It'll go thru
2 x 2 x 1/4 angle a lot faster than that, leaving a clean cut with no
burrs.
