Guys,
I am embarrassed to say I have not made more progress. I seem to go in "fits and starts" but I have not given up. I really hope to make progress just after the 1st of the year. This has been a very complicated project but I have the hardest hard work done as documented above. I now have the g-code validated for the receiver and have made most of the other parts. I will post as soon as I have something other than hollow promises.
Bill
