Re: 3/4" o.d. tubing
Fin.. If you make it up to Phoenix sometime, check out Industrial Metal Supply up on 48th St, south of Broadway. They have a great showroom that is half full of remnants dirt cheap. They have very nice 3' long DOM tubing remnants that they sell by the lb (scrap steel price). They should have plenty of thick wall 3/4" OD DOM tubing for you in various wall thicknesses.
