I didn't want to post this till it worked. Following the plans put on the net by another forum member (Norman Leonard) I started making parts about a month ago. It is now finished and although I haven't done any threading with it yet it seems to work as planned
A couple of resources:
Norman's Plans and information:

http://www.dennisatwood.com/projects/tumbler-reverse-for-10x22-lathe/I used two Acetyl, module 1.50, 30 teeth gears. Part #: A 1M 2MYZ15030 from Stock Drive Products. Dennis was kind enough to provide me with the part number.
Some changes were made:
- kept the change lever and lock mechanism inside the case.
- silver soldered the lever to the carrier plate after milling a "lap" joint - I don't have a welder and there was little room for bolts.
- moved the assembly around to the right (counter clockwise) from where Norman placed his.
And a couple of photos:
One of the real benefits is that I can now leave the drive train in neutral when it isn't needed. Plus I can make left hand threads (will likely never need one again now that I can do it).
Norm - thanks for creating these plans - I would not have figured out how to do it without your help.
John.
