where to buy: *threaded* aluminium pipe/fittings
I have been searching the web for a good source of aluminium pipe (between 1" and 2" thick) with threaded endings and matching fittings.
Can anyone suggest a good source? Searching the instructables forums I read about www.simplifiedbuilding.com, but they don't seem to have threaded fittings (only of a slip-on, use-a-set-screw kind).
Any suggestion greatly appreciated!
