[NJARC] Repair Tip (Jack Benny and my Dad would be very proud)

[john ruccolo]

Folks,

Speaking of Saturday's clinic, I took home a "homework
assignment" from the clinic, an early 50's RCA AM/FM
set. Among the set's many problems was a slipping dial
cord.

The dial cord was in good shape, and like most of us,
I HATE restringing them. But it did slip badly. I
thoroughly lubricated the tuning cap bearings with a
"cocktail" of lithium grease and very light machine
oil (LaBelle model train oil). That improved things
considerably, but the cord still slipped.

I then took some violin bow rosin and scraped off the
powder onto the loops of dial cord around the tuning
knob shaft. I did this several times. Wow! What a
difference! The set tunes perfectly now, and I avoided
the nauseating task of trying to restring or
tighten-up the cord.

My Dad was an avid amateur violinist, and gave me this
rosin many years ago. I'm sure you can get it at any
music shop.

Perhaps all of you knew about the violin rosin trick.
If so, please ignore me! ;-)

Regards,

John
