Hello everyone. I'm wanting to build a 2 X 48" belt grinder (sander), using off the the shelf, or scavanged hardware. I'd like it to be a 3 wheel, or maybe an idler pully with 2 others.
What I have in mind is to run a V belt from an 1800 rpm motor to a couple of pulleys, that will be adjustable in the vertical plane. I've been measuring car drive pulleys with the serpentine belt, and they all seem to be only 1" wide.
Questions: Has anyone here attemped this? Is there plans or ideas floating around. My main problem will be how to fashion the tracking mechanism. On my belt drive sander is apppears that one drive roller moves in and out to adjust the belt. Am I correct, or does the pulley move over at an angle? Any help help will save me weeks of experimenting!
