Whatever belt grinder you choose (I have the Viel), if it can be modified to take the Penn State variable speed motor it can easily be made to be reversible and the speed can be reduced to almost nothing. I have done both.
A small toggle switch can be added for reversing the direction. I have posted on this here and on the Viel FaceBook and on the Tormek Community Forum sites.
Also, with the Penn State motor controller, there are small pots inside on the circuit board that can be used to change the speed range. I posted on this on those sites as well. Easy to do and most useful. I've slowed the Viel down to were the motor jumps between stopped and moving, but don't use it there. I am not sure if slowing it down with the Low end pot ("L" in the photo below) has any effect on speed at the high end, but it doesn't matter as whatever grinding I do at higher speeds, the max. speed is more than enough.
Here is the link to the thread on this forum where the switch installation is discussed, posts #19 and 21:

I thought there was one regarding the pots for speed control, but have not found it yet. Nonetheless, we can help you with it if you go there.
