I've had have a Rockwell/Delta belt/disk sander for well over 20 years. The machine runs well, but lately I'm having trouble keeping the 12" disks glued to the platen. If I use the machine on a daily basis all seems well. However if it sits for a week or so the disks just seem to fall off.
At first I thought it might have been the quality of the disks I was purchasing. I had a bunch of self adhesive ones from a local farm store I thought might have been either old or of inferior quality. More recently I purchased a dozen ARC brand self adhesive ones from McMaster. I'm still having the same problem. With regular use they stay attached. With intermittent use they fall off in a week or so.
I've cleaned the platen of all residue, and even wiped it down with alcohol, but the problem still persists. When the disks come off they still seem to have plenty of adhesive. One thing I did notice with the McMaster disks is when they arrived they weren't perfectly flat. There was some arc on them in that they were shipped in a box slightly smaller than the diameter of the disks. Consequently they were on an angle in the box and may have developed an arc in transit.
I laid them flat on a shelf and put some weight on them to attempt to flatten them to no avail. Whenever I take one off the shelf the arc returns within a short period of time.
Any suggestions would be appreciated.
