We have good advice on heat treat, Rc numbers, Etc. I dislike hollow dowels because the annular holes required take too much material out of the rod and cap. The dowel also takes a bit away from the threads in the rod body. I have a heat treat outfit lined up, we have the steel lined up and the design is done, though I'm sure Pruit will have his guy run both models through FEA one more time, as I've tweaked the Mac rod a tiny bit, and the 820/610 rod is new. The original iteration of the 101 rod FEA'd out very well. The steel we're using is even better than the traditional 8620, though it does require a vacuum furnace for heat treat. I'm not worried about the design, just the processes. Ted
