anyone know where to get some? I have some 7/8th tube but apparently you cant really get 1/2" unf inserts to fit inside it. Im looking for something around 16g ideally.

I think that your best bet will be a hydraulics firm, if you have one local. That's how I got mine, after much searching of various steel suppliers. HTH Ray

cheers chippy. I think i might just end up notching the inserts around the weld and use regular erw tubing. Seems odd that no one can recommend specific places though?! I guess we must all be cheating

How much is it you are after Joel?

would've been about 4 metres but ive made a plan in my head now, conviniently its also cheaper! Cheers anyway if you were about to offer me some
