Kevin, I use two different types, depending on what I'm doing.
Tis one is free standing on a grinder stand I modified.
Heres a full pic. The bottom is a truck rim with 80# of concrete to weight it. I have since bolted it solid to the floor in my shed.
The second is a stand, like this that I saw and built for myself. I would recommend making it taller to save the back..
This type is good if you demonstrate, and also for cleaning.
Hope this helps
Bill
