  • 1x30 belt sander/grinder/

    I bought one of those $45 specials from harbor freight a while back and it was returned the same day because it lacked the power to even get up to speed. I also bought about 10 replacement belts at the same time that I didn't return, so I decided yesterday to make a new machine. I had an old HF engine stand in the scrap I used that, along with some 3/16 sheet. The top roller is a timing belt tensioner bearing for a Toyota camry that I had in the "surplus" box. The motor is from a worn out drill press. Took about 2 hours to build

    My tig welds are also improving

    Belt speed is a little low, so I'll look for a 3450 rpm motor, but it does ok for now.

    Once I get it where I want it, I'll blast and paint it so it looks pretty.

      Nice work there, I always like seeing stuff like this. Instead of swapping motors, how about a larger diameter wheel on the motor end? They are typically larger than what you have there.

        I'm gonna make a bigger pulley first. Right now belt speed is at 630 sfpm with a 1 3/8 drive pulley. I can go to a 3" drive pulley tomget to about 1375 sfpm...which will probably be fine, but that consumes another 4 inches of belt. Right now I've got it set up so I've got about 6 inches of the belt over a plate and another 6 usable inches off of the plate. I'll play with it a bit.
