Hi I am new here.  I have a family heirloom fan that has some issues, so I have been watching YouTube and reading up on how to do resto on my Emerson 29646.   The brass blades will just not come off.   One method I found was to screw in longer bolt into the left oscillator bolt hole, another method was to insert rod into hole indicated by pencil on right in pic.  Problem with that method was there is no hole on the rotor.  I also tried channel locks and they bent the bolts and just scratched up the hub.  And yes, I know it is a left hand thread.  Any tips?

I use the two hardened cap bolts and thread them into where the two upper gearbox mounting screws go.   You have to remove the gearbox, maybe not if they will tighten snugly to the rotor.   Common bolts will bend, especially if only one is used.

Heat the hub thoroughly with a heat gun before trying to unscrew the hub.

WORKED,   Thanks for the quick tips!   One more question, does this unit have a capacitor?  The original problem that was the impetus for tearing into it was the fact I had to finger start the fan into action.   Wondering if it has a common capacitor problem...

No capacitor in this fan. It could just need oiled real bad but if that isn't it could have burnt start windings in the stator.

Or a burnt speed coil winding. Or just a bad headwire. These fans, if I recall, need the speed coil to be installed to provide phase shift. My money is the headwire went bad. Was the fan oscillating frequently?

I recommend headwire that is designed for high flex. It should have high-strand-count wire (around 65 strands, not the common 7 or 19) and silicone insulation under the cloth overbraid. 
You can get OTR wire from Darryl Hudson or Antique Fan Parts. For the best wire, contact Tony Clayton. He custom makes wire on antique tooling.

it has not been used with oscillation much for the last 40 years that I know of,, but the headwire does look pretty shabby.    Will replace.

On these single-bearing Emersons, the headwire is sometimes good, but it is the most common failure.
