Maybe now I will get this project off the shelf ...a project begins

Picked up a surplus air driven belt grinder. With the parts from this I should be on the short route
to that long belt grinder I've been planning on making.
This thing was huge and almost unused and to heavy to use without a tool balancer.

So the sum of all parts is equal to the whole so this should be a good start, I want to replace the air
motor with an electric motor and stretch out the rollers to use a longer belt, the drive roller is about
2 and 1/2" diameter which is threaded the same as my angle grinder. I will have to work around that or
replace it. The motor I have is 1 1/4 hp, 3400 rpm which would run about 2225 fpm maybe to slow but the
other goodies should be easily usable. The small tension roller could be handy for small radius grinds.
I suspect that I will need more feet per minute which will require a larger drive wheel. Any suggestions
on belt speed before I get to far into this, the main use will be grinding forged blades or blades form
flat stock.

Maybe I could still use this with a cup wheel or wire brush 7200 rpm direct drive.
