Since the Suppliers thread is closed; posting a new thread of need here:
ISO a viable source for large oval tubing, such as would be used for boom tubes in tandem construction?
I am about out of old stock and the two companies in the US which used to produce them have elected to not do so anymore.
While we can order them from Ceeway in the UK for USD $42 each plus shipping, my goal has always been to source everything practical from US based producers.
So if anyone knows of a source, would appreciate a posting. If it is a secret source then a PM would be fine also.
