I was at a hardware store and saw a nice stainless steel garbage can that wouldn't have taken much to make into a drum throne. I thought about it but it was expensive, like $80.

Maybe there's some plastic sewer pipe that's the right diameter, hard to imagine there isn't and that a remnant would cost much... that might be worth thinking about.

You've probably seen the newer design ones that are two tubes that slide into each other so you can adjust the height. That would be another way to go although if it's custom you wouldn't need the adjustment and they don't look as cool as the Buddy Rich kind.

I used to sell laminate and plwood to cabinet makers.There is a plywood product called quarter rounds which come in a variety of sizes. Don't think you'll find em at the Home depot but,try Googling it and asle do a local search for lumber yards and cabinet component distributors. You'd have to buy 4 natch and glue them but,should be way cheaper than a Keller shell.

Anyone have the dimensions of a canister throne?

I made one once out of a Keller plywood tube that I got from an arcitectural wood supply outfit. I think if you google plywood tubes you might come up with something. It was a very handy throne. I kept my sticks and pedal and tools in mine.

Check out anderson international, they have shells upwards of 24 inches deep and 15inch diameters. Dw has one that I think is pretty cool and Jim Petty has one also.

You also might try PVC pipe in 12" dia. Especially if you plan on wrapping it. Would be a lot cheaper than wood.
