I would appreciate some input on the correct material for hanging and engine on a dynafocal ring mount. I have read a few posts on some other message boards and would like info from the Thorp community. Specifically I am questioning the length of the spacer rod/tube that came with my new set of Lord mounts. It measures 58/32" in length. The Lord biscuits are each 27/32". My dynafocal mount cup is 29/32" thick. I have read that the rod/tube is to prevent over compression of the biscuits. If that is the case then summing up the parts I get an interior distance of (27/32 + 29/32 + 27/32 = 84/32") The rod being only 58/32" would allow a compression of nearly half of both biscuits. The next puzzle is HOW to compress the biscuits this much; the length would be 26/32" yet the thread length on an AN7- bolt is only 21/32".
Is the rod spacer the incorrect length? Are the biscuits not to be snugged tight to the spacer rod? Is my dynafocal cup too thick? Am I using the incorrect Lord set? What length bolt is correct? Do I fabricate a new longer spacer?

I believe that the plans show the proper length of the spacer.
