help - fitting sleeves to Delta Boss sanding 'bobbins'

I wonder if anyone can help. I have a: Delta Industrial Model SA350K Bench Oscillating Spindle Sander and I have recently bought new abrasive loadings for it - changed all the smaller sizes without problem - but just can't get the largest drum to load - the sleeve seems too tight. I can get the sleeve about 1/3rd of the way up the drum, but that's it. Is there a trick I am missing? Perserverance and persuasion just don't work...
Thanks in anticipation Liam (from the UK)

I hope someone shows up with a good answer. Once the rubber has been expanded, it seems impossible to install fresh sandpaper sleeves. I noticed on a new drum that I acquired recently that there was something a bit like talcum powder on the rubber. I keep meaning to take some to the shop to try.

I really hope so - the sleeves cost > $ 10 each and I've 'worried' a couple already!

First, release the pressure, then compress the sleeve with 2 or 3 hose clamps. Leave it over night. Remove the clamps,apply talc or baby powder (smells better and relives any rash). Finally, release the pressure after each use!!! Gene

Absolutely. Little bit of friction reducer to get it over the residual bump is the answer for changing grits where you don't have the time to squeeze and wait.
Of course, those who watch Oprah know that talc is the cousin of asbestos, so they use the cornstarch.

Many thanks for your help. I really appreciate the advice.
I have tried the 'friction reducer' approach, unsuccessfully unfortunately - but will do so again (after using hose clamps). Thanks.
I now wonder if I am missing something more fundamental:
Do I gather that leaving the spindle on the machine will encourage 'growth'? (I never did work out why there is only one washer - which I assume is placed at the top of the spindle. It seems a little odd that there is only a knurled shoulder at the lower end to support the drum (i.e. very small in relation to the larger diameter drums.
Thanks for your patience and advice Liam

Liam,
The sandpaper sleeve can be difficult to install sometimes; and remove too.
It might be quicker to just buy a new rubber drum. In case you missed it the rubber drums are also the same as used by the Sears and Ryobi oscillating sanders. (Home Depot carried the rubber drums at one time, might still.) You might even want to have a drum for each sleeve grit you use.
Some of the sandpaper sleeves may be a touch short in the quality department. Check Klingspor, (www.woodworkingshop.com), they carry 3 grits in 6 sleeve sizes according to their No. 93, 2007 catalog.
I don't know what access you have in the UK to the above companies, but good luck searching.
Note: I do not keep the drum under tension when I'm are not going to use it for awhile. I do this to avoid distorting the rubber cylinder.

IIRC (and I'm too lazy to check) rubber expands in the cold. It's weird like that.

From actual experience with Delta B.O.S.S. it works. (It is synthetic rubber)
