Tension Screw Repair

By bullmastiff
It was my wife's fault: 1952 Delta 6x48 Belt Sander, mostly

This is an alternative to the solution presented below to the problem of the tension screw wearing against the inside of the casting, allowing the end of the tension screw to protrude past the plane of the platen and get in the way of sanding. The idea came from scw1991 from the thread Delta 6x48 31-730 sander repair details(16 pictures)

Another problem point is that the end of the tightening screw wears where the threads rest against a shoulder in the casting. This causes the end to stick up above the bed and becomes a nuisance.













The shoulder in question inside the casting













Typical of any sander disassembly













The bad shoulder













Turning the shoulder down a bit. Also, the end was turned back that amount and a little taken off the housing shown two photos up.

Fabricating Tensioner Parts

By Jeff Miller
My $200.00 Delta sander pictuers

I brought home a sander with the spring and sleeve missing from the belt tensioning mechanism.













I studied the parts breakdown pic., bought some springs (TSC) used some 1" square tubing welded some small ears on the end that pulls on the dog to push up on the idler, welded a piece on the other end and drilled a 1\2" hole in it found a square 7\16" nut. I gussed on the length of tubing and length of springs. I have a new 7\16" rod I am going to thread yet but wanted to make sure it would work first. And it works really well. Total cost $11.00
