I sent a part sample as pattern before Christmas and now I can not get them to answer emails or phone calls. My first choice, have Aero Adventure (FL) do the job, they said they can. Helens OR that advertised mandrel tube bending and they just told me 'no can do'. As this sort of thing quite common on many ultralight designs, I figured living in Portland metro area home of Van's aircraft and several other kit aircraft businesses, I should have no problem finding a shop to bend thin wall aluminum tube. several tight bends required in 6061-t6 1' dia, 0.049' and 0.065' thick walled tubes.
Have several parts to fabricate for a Buccaneer 2 project. If they can't do the work, they should know who will. Find yourself a local hydraulic supply house.
