[Boatanchors] Fixing the dial drive of a BC-1004 (or SP-200 series)

[Philip Atchley]

Hi,

The other day I posted a question about the tuning dial.  Some suggested 
tightening the nut on the shaft ext.  That was already as tight as it 
would go.

However, I 'think' I've found a fix.  While the RF deck was out I 
removed both tuning shafts, split washers etc.  Both had the same 
dimensioned components,
but the main tuning (working) "drive" washers were "concave" while the 
malfunctioning ones in the bandspread drive were not, causing them to be 
wider spaced.  Laying the thin, sheetmetal washers on the carpeted 
table, "lip" side down, I placed the rounded handle of a screwdriver on 
the washer and "smacked" it with a hammer.  This restored the concave 
shape.  I'll know if that fixed it when I reinstall the RF deck (after 
other work on the main chassis is finished.  But it DOES now look like 
the main tuning drive that was working and spaced about the same. Before 
this "mod" the space between the two washers of the bandspread drive was 
very noticeably wider to the naked eye.
