[Heath] Need help accessing the Heath Archives....

It's been ages since I've torn into any of the Heathkit LMOs  (tube as well 
as the newer solid-state ones), but I'm pretty sure the  tuning range on 
that capacitor is PURPOSELY limited to LESS than 180  degrees of travel 
(corresponding to the designed.........and slightly  less than...........5 1/2 
turn rotation range of the shaft that the "0-100" dial  scale fastens 
to).........once this intended and limited range is exceeded, the  tuning linearity 
(and resulting dial calibration) would be quickly  degraded.   A properly 
working "SB" dial (TX, RX, or transceiver)  should cover 500 KHz, with only 
about 10-15 KHz of "overrange" on either end,  requiring significantly less 
than 180 degrees of the internal LMO tuning  capacitor's shaft rotation.

How do you do it?  I'm rebuilding an LMO, setting up  the stops, and I 
can't get a full 180 degrees on the variable cap inside the  LMO....I get 
"almost" 180, but not quite....would like to read the archives,  as I'm sure 
someone else has delved into this before.
