Sounds good. I was putting a drop of oil a month or so, but looks like even that much would not be needed.
As far as the drive belts, I've given up on the replacement belts for the Thumler's model B. The darn things were breaking every 4th or 5th tumble for no apparent reason whatsoever. Very frustrating and expensive.
I switched to o-rings as well. I ordered several ethylene-propylene o-rings of the same size as the Thumbler's belt. The o-rings cost 80 cents apiece as opposed to $5-$6 a pop for a replacement belt.
I'm still using the first o-ring after months of tumbling, and it shows no signs of giving it up.
Here's the link to the exact ethylene propylene o-ring I am using on the Thumlers:
