Have made this little jig some time ago but never posted it but today I needed to make some little discs to fit into a half pipe but did not want a hole in them and I took some pictures along the way .
I made them with this little jig that is clamped to my 12” disc sander ,I simply made a plywood disc on the band saw and drilled a 1/4” centre hole so it would fit over the dowel on the sliding part of the jig .
The jig has a sliding stop that can be set anywhere along the sliding part of the jig and is locked in place with a bolt from the bottom .
A second bolt through the block from the end acts as a fine adjustment and lets me sand the disc to a very tight fit by sneaking up to the diameter .
The sliding part of the jig lets me sand gradually toward the rough finish size by moving it toward the sander and rotating at the same time and with the fine adjustment set to oversize I can slowly adjust the bolt and sneak up at the final size .
The thin disks that I needed are rough cut on the band saw and fastened to the plywood disc with two sided tape and sanded on the disc sander giving me the exact size of disc with no centre hole . This allows me to make any number of disks the exact same size .
