Hi, fellow rotary enthusiasts. (rotariasts)?  Attached are two photos of the work I had done on my
2.17:1 Ross PSRU. The work was done by Dave Mix. He can be reached at harborview@rivnet.net   I am
very pleased with both the quality of his work and the fast turn-around time.  As many of you
know, each Ross is a little different (tolerances), requiring possibly different solutions to each
one to eliminate play, etc. Due to the amount of material remaining on my center shaft, it appears
that this was the best fix for my particular unit. Dave will measure each unit and propose the
best method for that particular unit.  When I find a vendor that does a good job and provides
expedient service, I like to pass it on. The cost for this mod was $225.00 plus shipping. More
than worth if in peace of mind. Paul Conner, 13B powered SQ2000 under construction.


I think you need two or more of these needle bearings Paul. Needle bearings
don't like to operate at high speed. If you use two back to back  the speed is cut in
half for each. I can save you a lot of heartache if you check with me on this
stuff before you have it made. We have been over this situation many many times
in the past. The last jpg shows how it should be done.

BTW Mark this might be a good one for best practices.
