Thanks for the heads up Torauni-
I was considering using one of those to elevate my tub if Bob hadn't given them away,
I have a third tub here at my shop....
I want to try it out but I've got no pump as yet-
Anyway I'm float'n my tub out there tomarrow and go'in to work!
You know me-
build'n the west-wing on the shack and kite'n
