Hey Tombstone,
I forgot to say thanks for the heads up on the PVC tubes. I used my wife's ebay account and bought the 4 inch canisters.
I will post a reply when they arrive.

If you order a plastic tube for tumbling from this seller, have them measure the inside I.D. of the canister your interested in buying before ordering.
The reason is that the inside I.D. s aren't always compatible with all of Jar Doctor's stopples.
The seller is really great to work with and will be happy to help you.
You can't beat the prices for these clear tubes (even with the cost of shipping).
