Just finished a Philco Model 77 and it is playing great, but......
I noticed that the dial string was a bit loose, so decided to replace it. I have used regular dial string as well as copper braid, but both slip on the drive pulley attached to the tuning knob. The original string was thicker and a bit softer than usual. I think I need a large diameter string. Any tips on how to solve this or where I can find the correct dial string?
Thanks,
Joe

Assuming the pulleys turn freely-a little soldering paste on the pulley groove greatly increases traction for the string,though what you're using looks a little thin....

I found that if I take an old wax capacitor and run it along the string, getting some wax on the string it makes the string grip a little better.
The wax at the ends of the cap seem to work pretty good.

^A wax candle can be used as well.

What I do from time to time put heat shrink tubing where the dial string runs works great - it's rubbery and not sticky like tape.

Also - don't assume that the way you found the old stringing jog to be right. Make sure you have the string in the right place (does it run on top of the shaft or underneath?) - plus make sure you have the correct number of turns around the shaft and that they are going the right direction.

Darn it. I cleaned the pulley's. Now I have to figure out another fix.
I'll look for the Philco 77 dial stringing instructions to make sure I am stringing it per the original design.

Well don't worry if you can't find the diagram, you'll eventually figure it out. I did one a couple of weeks ago and it took me two and a half hours to figure it out. I used a lot of string doing it - but luckily I have a big roll of old radio string that will last my lifetime and my sons as well.

Bye the way, you can use smaller string. The stuff I use is thiner than most and I have never had a problem.

Well, I figured it out. It is NOT the size of the string. I added a full loop of regular dial string around the pulley connected to the knob. Before it was only a partial turn. Works fine now.
Thanks everyone..
Joe
