[TowerTalk] Ham IV rotor reassembly

[Barry Gross]

What the emails all basically said was that the bearing retainer flanges should be oriented toward the center of the rotor.  If you look at the middle photo of http://n1eu.com/ham4.jpg , you're looking at the bottom bearings (rotor is upside down) and the retainer flange (up in the photo) is incorrectly oriented toward the bottom of the rotor instead of toward the center.

I do wish these helpful emails had been posted to the list. I am in the same predicament.

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

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,
