The RV bending die set will work on 3/4 x 3/4 x 1/8 angle longerons found on Vans RV series airplanes.
Does the idea of clamping your longerons in a vise and whacking it with a hammer sound a bit crude? If you want accuracy and control, then you need a set of RV Longeron Dies.
Who is this longeron guy and how did he die? We think he committed suicide after trying to make airplane parts out of 3/4″ angle, using a Hammer and vise 🙂
These dies bend both the vertical and horizontal flanges of the angle so that the angle does not twist as you bend it.
