[Boatanchors] BC-1004 slipping dial

Hi,

I've searched the Hammarlund Archives and found references to dial 
slippage, but nothing "fixed" it (cleaning etc).  The BC-1004 that I'm 
working on (Basically a Hammarlund SP-200 series receiver) has a bad 
case of the "Hammy Slippage" on the bandspread dial, requiring much 
spinning of the bandspread tuning to "eventually" tune across the spread 
of the dial.

Things checked:
1.  Plastic Dial and the split washers were cleaned of any grease, dirt 
etc.
2.  Tuning capacitor turns freely, doesn't seem to be binding.
3.  Dial is Warped some, but meshes with the split washer ok.
4.  Slot in the split washer seems to be wider than the main tuning 
(which works stiffly), but I can't figure any way to "tighten" the split 
in the washer.  Working quarters is quite cramped between front of the 
chassis and the coil compartment.

All ideas appreciated.
