[TowerTalk] M2 Orion 2800 Rebuild?

[Rob Santello]

Hi Group,

   I just acquired a very used M2 Orion 2800 rotor that has had a tough 
life turning a full size MonstIR SteppIR for the past 9 years. It was 
working when removed but had some rust on it and the 1/4" bolt that 
holds the plate onto the shaft was broke with the threaded part 
remaining in the shaft. It can hopefully be removed with an easyout 
extractor. I don't think that will hurt the rotor but mostly wonder how 
difficult it is to open it up for an inspection to check its overall 
condition. There are plenty of documented rebuilds of Hy-Gain rotors on 
the web but I can't find any example showing someone rebuilding one of 
these. I know water getting into the 2800 has been a problem and I'm 
concerned with the visible rust on the top that there might be more 
internally. So how difficult is it to open one of these up  to take a 
look inside. Is there a specific procedure or ideal sequence of steps 
that should be observed when opening one and appreciate any pointers as 
to what I need to check once inside?

   And while I'm here, does anyone have a used Green Heron RT-21 
controller they would consider selling?

Thanks,
Rob
