RE: sonotube?

For that size, forget the sonotubes which can be expensive as they get up in
size. Much better to go to salvage yard
and get a polyethylene water tank or something which usually can be had next
to nothing. I believe thats what both Ed Wingate and Terry Blake are using
for their magnifiers.

HI All
Does anybody know what ""sonotube"" is called in the UK as
I want some 20" dia to build a new maggie driver on.
