I achieved success thanks to several helpful emails - I had the races ass
backwards (i.e., races aren't necessarily those smooth polished surfaces).

Subject: Re: [TowerTalk] Ham IV rotor reassembly
I disassembled and checked - bearing retainers were correct. I posted photo
series showing the reassembly:
http://n1eu.com/ham4.jpg
If there are any experts out there, perhaps you could comment on the first
photo
and whether the vertical level of the lower bearing race looks correct. The
last photo in the series shows the slightly too large gap to bridge - it's very
close but just can't get all screws threaded.
Unless a light bulb goes off somewhere, I'll send it on to one of the rotor
experts to sort out.
Tnx/73,
