Excellent, I read to the end with trepidation about that thread direction once that seemed most likely. The octagon is not easy to grab as it tapers a bit and is radiused at the root. If I had socket it would be simple enough to push inward to keep engaged but I would have to make one by padding four sides of a larger or bending and welding an octoganal loop with drive square in crosspiece. I'll go out and try it now. Report back in a bit boys!
