The press brake has its advantages in forming hat and zee sections but the upper dies would need modified for the 1/8 " radius and the lower die would require rounding and polishing. The shear you will find invaluable and the slip roll less so. The size of sheet goods a plans builder deals with are 4'x12', and many of the control surface spars exceed 5'in length on a 701, the longerons 6'. To attempt bending the .040 (18ga) longerons in anything less than an 8'x16guage commercial brake or equivalant(with radius die and proper adjustment) is an excercise in frustration. Buy the plan, do the material take off and sheet layout (on paper), figure out what the 40" brake will and won't handle and make a decision. IMHO it would make a nice addition to a well equiped shop or a decent beginning of one. What you save by plans building is partially offset by the cost of tool aquisition and the learning curve of building parts to meet tolerance. Disclaimer; I have never used one of the 3in1 machines and cannot comment on its suitability, best bet is to road test somebody else's.

But no... can not remember the brand name now. It was cheap Chinese junk. I took a look at the brake plans on the Vans website....looks extreamly like the plans Zenith used to offer. do not archive
