cardboard 130mm tubes

[balloonboy (Greg)]

Hi all

Could anyone tell me if there is anywhere in Perth that sells 5" (130mm) sturdy card board tubes? I need to a shorter tube to stick my SW135 primary / secondary / focuser in, so to avoid cutting bits off the existing tube....

thanks in advance
Greg

I don't think there's anywhere that will sell you a single tube. I did talk to someone about cardboard tubes once and I had to buy a batch of them (which was ok as I was thinking of running a scope making course at the time, but it didn't go ahead). Best bet might be getting a new metal tube made at a fabricators.
