I recently made this 2" belt sander. The deciding factor for making it instead of buying one was scoring the 3/4 hp motor
for free from a friend.
I machined the pulleys myself from black delrin and the rest is just steel tubing and plate and cold rolled steel for the shafting. The rest of the mechanical
parts are from McMaster Carr. I made the whole thing for under $150 and I think I made out like a bandit. This thing rips!
I saw some other people have made there own sanders on here as well, awesome!
[quote="Fat Bob"]Very nice job Elliot! How strong is the spring to tension the paper on the upper arm? It looks pretty healthy.
The spring had to be much stronger than I anticipated. I had several of the same ones on hand, or I doubled up on them
after concluding the one wasn't strong enough. I bet the two of them are offering somewhere in the neighborhood of
60 lbs!
Thats awesome. Nice ingenuity. See if you can design a pipe notching attachment for a side project.

Thats a great idea. I had actually already considered extending the output shaft of the motor to do so. Or perhaps some
sort of grinding wheel... If come up with something I will post some pics!
