I have no answers for the OP, but I will say this. It might be better to
use only four of the six mount holes rather than compromise all four of
the other set.


I got a look at a "stock adaptor for a 100mm PCD adaptor. Only 4 holes are
drilled for the 6 hole side so that looks like the solution.

Never realized how much I have saved with my mill and lathe. Took the
drawings down to a local machine shop and got a price of $240 each for the
adaptors. They are just a 4.5" diameter round 7/8" thick bored 1.75" with
a 3"x 1/4" relief on one face and a 1/8"x1/8" spigot around the bore on the
other. I can turn them both out in half a day on my antique 10K. In
making parts for Rutu I figure I have paid for both the mill and the lathe 5
or 6 times. Of course, I bill my time at $.01/hour after the satisfaction
discount. :-)
