To all-ya-all,

Saturday I drove over to Roy Sarafinski's garage (pole barn) to see 
first hand his 5th bearing solution. He posted a link here to 
roysgarage.com and I replied back with "Nice work.  When do you want me
 
to bring you my engine? ;-)   Where are you located?  I would like to 
visit."  We emailed and talked on the phone resulting in my trip his 
facility.

I met Roy and entered his home/shop and there it was on an engine 
stand.  Roy has done some serious thinking on the  design of this 
elegant approach.  In essence what he has done is solidly extend the 
case and crankshaft of the Corvair flight engine.  All his work is
 close 
tolerance and strong. Roy has a very complete facility for doing this 
kind of work and the finished product is first class.

Roy's plane, a CH701  is quite away from flying, as is mine, a 601XL.  
Roy designed this for himself because of the high angle of attack the 
701 has, and like me doesn't want to spend the money for the other 
flight engines out there. I would like to see someone build up a BigBoy
 
with this solution and try some aerobatics, it looks that strong.

Roy is also doing some very interesting work on dual plug electronic 
ignition/injection systems.  The dual plug method he has perfected 
removes very little of the cooling fins on the cylinder heads.  I also 
got a lesson in Wasted Spark systems from Roy,  think I even understand
 
it now.

Anyway, just wanted to give a report about a guy doing some really good
 
stuff out there and to encourage others to look him up.
