Well I have a project that requires me to build weld up on a shaft where the bearing race surface is. Been contemplating this for quite awhile as to needing one for previous projects. Started out looking on E-Bay for a gear motor (Oriental Gear Motors), found one with speed control for $49.00 used. then found on E-Bay also two 1" flange bearings for $15.00.
Local repair shop that rebuilds starters / generators had the brush assembly $10.00. Steel beam has been in the family for about 40 + years as a door stop, wheel chock,
frame jack and ????????? over the years. Now it has a new coat of paint is looks as if it is new again!
Used 1" cold rolled steel for the shaft and turned and bored a brass collar for the ground. Also had to make a lovejoy connector to match the one that was on the motor.
Paint, bearings, motor, bolts, nuts , washers ----------total less than $100.00
This is only a small basic bench style but now I have an idea to make a larger one if need be.
Motor gear box 120/1 max RPM 16. Experimenting I found out that you have to get down to around 2 - RPM for a decent weld bead.
It was lots of fun to build and definetly killed some cabin fever blues!!!!!!!

Very cool. If you need you can even add more brushes. What diameter are you welding? RPM should be inversely proportional to diameter.
