Subject:
Holding Water

Georg Waldhof
>Ok - here's my bizarre question of the day:

Anyone have any experience turning wooden bowls to hold water? Specifically, I'm thinking something that needs to hold about 3 to 5 gallons of water for as much as 30 hours.

I figure I need:

- close grain wood (not oak) with well sealed glue joints
- waterproof glue
- a big lathe.

I have all that. What sort of sealant would be good? I'm wondering how Spar varnish, or even paint might hold up? This does not need to be food grade or anything since no one will be eating or drinking out of it. What about catalized laquer?

Thoughts and suggestions? Right now I'm thinking of gluing it up out of cherry, mahogany or makore, turning it and sealing everything up with spar varnish.

Thanks

George
