Guys, I have my copy of Marsden, Technical Treatises in front of me. Payne-Gallwey set up his buffer to halt the arm at 75 degrees to the horizontal, but as Duncan pointed out, the jointry kept coming loose. He then, according to Marsden, put his buffer to stop the arm at full upright position of the arm.
Schramm was religious about keeping his arm stopping in it's forwad momentum at 67.5 percent, and set the bufffer at that angle, and the arm kept breaking, so he later placed his buffer at 75 degrees, and that resolved the breakage issues. Marsden reports that his small machine worked prefectly following Payne-Gallwey, and he never needed the spare arm he had built, just incase.
None of this should be taken religioiusly, though. Payne-Gallwey, in his book of the crossbow, illustrates the thumb ring for archery as being worn backwards, and if one were too try it that way, it would be an ugly injury he would suffer.
