Thanks Russell,

Actually, I am working on a set of guidelines that builders can use to trim
a few pounds off the RD-1A/B.  The work to do it is not suitable for low
cost CNC so I don't think it will ever be done here but if saving 4-6 pounds
is worth the 5 - 20 hours it would take to do it then it might be worth
while for individuals.  The RD-1B I'm now flying has about 3 1/2 pounds
taken out of it and I don't think strength has been compromised at all.

I have my own suggestions :-) Here is a sketch.
If you have an NC mill the real trick thing to do is pocket out
the adapter plate leaving thin webs and ribs instead of cutting 
large holes.
