Repo large tuning knob for Scott Philharmonic and model Sixteen.

[David C. Poland]

Needed the large tuning knob but failed to find one at several radio meets, so I had a few repos made for my use and a couple spares. 

Not the wood "S" style, rather of the brown bakelite set used for the late 1930's Philharmonic and Sixteen.

My source original large tuning knob is dark brown with 2 set screws.

The repo is casting resin using a mold from the original. Good color match with 2 set screws.

See photo of a repo on my late Philharmonic and another laying in front of the radio.

Maybe a few others need this knob, too.

I have an extra repo tuning knob I would sell for $20, including mailing 1st class within continental U.S.     Depending on interest I may have a few more made just like it with set screw, but need to gage interest over the next couple weeks.

If interested, e-mail me at [e-mail]

Have you ever thought of making copper escutcheons by electro forming?

[David C. Poland]

Mike - Not familiar with the process. And not in my "wheelhouse".

[mike hadley]

Take a silicone mould from a scott escutcheon and make this conductive by rubbing the surface with powdered graphite, this can then be electroplated with copper, I used to do this as a kid with candle wax and coins etc works reallly well.

I suppose penneys provide the copper. How do you connect a battery wire to the graphite coating? And can you attract enough copper to build a rigid form? 

[mike hadley]

The mould is coated with graphite and the surface worked with a soft brush until it takes on a metallic lustre, this becomes the cathode, the mould is then submerged in a copper sulfate solution with a copper anode and plated, a very thick layer can be grown in this way,
As a kid I made copies of pennies, if the plating was left for a day or so the resultant coin could be anywhere up To 1/8 inch thick, the trick is to keep the current low and not to "burn the copper otherwise a spongy layer would result.,
I think the best thing is possibly make one and post the result.
