Made mine out of 2mm aluminium sheet & rolled. Steel strengthening bands each end. Plenty strong enough.

Zane, you might want to try 'Sonotube'. A very strong, thick walled, builder's cardboard tube, used for concrete column moulds. It's what the Meade DOBs are made from. Great thermal qualities etc etc... + they don't rust!
HTH. :D L.

Good to know that you do rolled aluminium Mick! I didn't know that. Full of suprises aren't you!!!!
I will keep that in mind for future reference.
