October 6, 20205 yr Some time ago I bought a $40.00 sander used and beat, really beat. It'd been owned by a welder. I had to do the bearings. the disk part was wrecked but I wasn't interested in that. But it had an impossible problem. Nothing I could do with the thing would get it to track correctly. - The adjusters were these cheesy cams that moved way too much with too little input. So they were useless. I replaced them with these difficult shop made gizmos that allowed me to use screws to adjust the tracking but it was scary to use because I have to be working inside the thing as it was running. So i decided that an new improved version was in order. Not I can adjust it safely from outside the belt and it is much finer than even the screws I made up a1/4" plate and mounted the adjustment hardware that I designed and machined on it. Then bolted that in a notch I machined out of the cast iron with a little10-32 screw. later i will braze it in place. but it works perfectly now. it's a simple mechanism
