Are you using the correct size washer between sanding drum and the nut (locking screw)?

does sound like a spacer issue. But if the sanding tube is installed properly. The sand paper stopping to spin is a common problem on osculating spindle sanders. If you put a piece of paper or some painters tape on the round tube or sand paper belt, then put the sand paper on the tube, this will fill the gap giving you the pressure needed for sanding.

I don’t have this problem except for the smallest sleeve (1/2”). All the others have a rubber form that the proper washer fits against and the knob runs down to it and expands the form into the sanding sleeve.
On the smallest sleeve it just fits over the steel spindle, and then with the proper washer setup, runs up against the sleeve. The sleeve is easily crushed, and then tends to slip.
Perhaps the masking tape suggestion will help?

Every once in awhile mine will slip and I just tighten the knob on top.

I noticed I couldnt tighten the locking knob enough without very firmly gripping the sanding sleeve and really cranking to locking knob down. Otherwise it wouldnt quite put enough pressure on the sleeve to keep it from slipping on the spindle.

Hope this helps.

There is a black piece that goes on the spindle when you use the drums. It acts as a fan to push sawdust towards the exhaust port. It also acts as a spacer to lift the drum. It is about 2.5” in diameter and 0.5” tall.

It never gets used with the belt sander, so it may have been misplaced if you have used the belt exclusively for years. A stack of washers at the bottom of the spindle might be a workaround.

I had some issues getting the knob tight enough to grip the rubber sleeve. Picked up a reverse thread nut at Ace Hardware & it tightens as much as needed. Also handy when I’m sanding taller pieces with 3/4” sleeve since the nut & washer don’t exceed dia of the sleeve like the base of the knob does.

Steve, I just checked on ereplacement.com and that part is discontinued. So I may have never been packaged up with the sander. I did find the washers and will be ordering them, not sure if they are going to work

I tested my sander using a stack of washers and it works, but is not too great. The sandpaper sleeve wanted to slide downwards. The black plastic part prevents this. A top washer larger than the sandpaper sleeve would have also prevented this. I was using the 2” diameter sanding sleeve with a 1” diameter washer.

Looking at the part, it would be really easy to make a replacement. Make a 2.35” circle out of plywood that is 0.65” thick. Drill a 5/8” hole in the center that goes half way through the part. Drill a 1/2” hole the rest of the way through. Chisel out a 1/5” deep groove around the 5/8” hole that is large enough to fit over the pin on the spindle.

You will also need to create a 1/4” by 1/4” rabbet around the lower outer edges so the part has enough clearance when the spindle is at its lowest position.

Hope this makes sense. It should work nearly as good as the original part except that it does not have the tiny fan blades to help clear sawdust.
