I agree with Kelly on this.  Quite aside from any structural considerations,  in looking at Tracy's exploded view of the RD assembly, it appears that you would be moving the whole main gear housing assembly 1/4 inch closer to the eccentric shaft and trying to force the input shaft/sun gear 1/4 inch deeper into the planetary gears.  From examination of my uninstalled RD-1B, I believe that all shaft lengths, bearings, thrust bearings, clearances,etc, are carefully based on use of the 1/2 inch plate, and it would be impossible to use anything thinner.  Dean Van Winkle

Thanks, Dean, but the RD-1 measurements won't be a consideration.  I have a different PSRU.
