Delta B.O.S.S.

[ChuckD]

I have a Delta BOSS, a oscillating sander.  I have a major problem with it.  The sanding sleeves are always creeping up as I sand.  How can I prevent this.  I have tried two way tape and other ideas but they still creep.  Anyone out there have any ideas?

I don't have a Delta B.O.S.S., I have a Ridgid O.S.S. and I've noticed that you have to tighten the top nut really tight to expand the rubber inside the sand paper sleeve sometimes to hold it in place. I think it has something to do  with how old it is or how much the sleeve has been used. Also it might depend on the brand of sandpaper used.
I assume you have tried more than one sandpaper sleeve so, my next step would be to warm the rubber plug up a bit. I don't mean a flame but, maybe aim a heat gun or hair dryer at it (with it off the machine) to expand it before installing the sand paper. Also, make sure the rubber plug is nice and clean. Wipe it down with some thinner, again, don't soak it just wipe it off a bit.  Cold and sanding dust does strange things to tools and equipment sometimes. 
Hope that helps.

P.S. Another thing that I forgot....are you using a washer under the top nut? If so, make sure that the inner diameter of the washer is just big enough to go over the shaft and the outer diameter is just a bit (1/4") smaller than the rubber plug to get good squish out of the rubber to tighten up the sandpaper sleeve.

I have a couple of BOSS sanders in my school shop. I put a large flat washer on the bottom of the sleeve and then a smaller one on the top of the sleeve. The added washers give the nut more compression force and squish the drum to hold on to the sandpaper.

I have a washer for the top but not on the bottom.  I will try that.  Thanks

I had the same problem a few years ago. My fix...the washer. I guess if I would have read the instructions I would have figured it out. Doh!

I got this for $50 at a garage sale so no instructions.  I will check and see if I can find some..  Thanks for all the suggestions.

My BOSSes have been nearly bullet proof so far. I have had them in the shop for 7 years, with about 300 middle school kids every year using them. The double washer trick should work for you.

Another trick to keep in mind. If you ever can't get a sleeve on or off of the rubber drum, put the drum in the freezer for a few hours. The cold will shrink the rubber just enough to slide the sleeve on and when it warms up you are good to go. The first time I asked the Home-Ec teacher if I could put my sanding sleeve in her freezer she gave me quite a funny look, but it works!
