I made my own bent stick out of stainless steel. I first bent the 316 seamless, stainless steel tubing with two bends . I got a few wrinkles on the inside radius but not too bad . I have a homemade bender with dies for 1 in. od tube. Then tig welded in a pivot tube, clevis, and a cupped washer on the wire outlet hole for a doubler.Then welded a custom receiver that is "tilted" forward to position the Tosten grip in the correct attitude. The custom receiver has three set screws to lock the grip into position ( in case one or two come loose ) Then positioned a dowel pin in the pivot bushing and clamped the dowel in a large vice and bolted a fixed block in push rod clevis. Using a large fish scale we load tested it in all directions for deflection and bending. I don't remember the load but I used 2X the number that I found on this sight some where. I'm not sure but I think it was something like 80 lbs. that we pulled on it in all directions.
I would think one could tig weld a custom receiver end in a stock bent stick and make the Tosten grip work just fine. I have about 3/8 in clearance between cooley switch and bottom of panel and can loosen the set screws and rotate the grip to what feels good.Moved it once after initial flight. Ron
I know this is an old thread, but are there any commercial sources for the bent sticks? I notice a HUGE difference in comfort between the bent stick (good) and the straight stick (not great).
