RE: Zroli 20 (?)year old 1/2A 42"span Jenny
Just another thought to build off of Bipe's idea, but if you had struts that needed to be at an angle (though I don't think the Jenny does) you could use an entire small pinned hinge. Trim the exposed side down some and then pin one side to the rib with the hinge line even with the bottom (or top) of the wing. Then no need to bother with bending to exact angle, just cut a proper length strut and let the hinge flex to the right position.
Never tried this of course, just a new idea.
