I never thought about using water slide for caps. I bet that would work with a scan of a paper cap tube that was unwound also.
I normaly don't care to go to that much effort for originality, but I have an Arvin what I'm found of. John |

I normally wouldn't bother either, but I was curious to give it a try.

I got my paper from this place. It works fine with an inkjet printer. Use it like you would glossy photo paper. I've used it before to make decals for TV controls like this. They recommend using clear acrylic for the decal backing but I used lacquer. Works just fine. Last edited by bandersen; 11-26-2009 at 10:59 PM. |

Neat re-stuffing! Very "fulfilling" on turkey day.

I've got them both running
The turkey must have jogged a few brain cells, because I finally found the problem in the first set.
When I recapped it, I inadvertently broke a crucial ground connection Those two tube pins should be shorted together! Here's one of the radios all done with the rebuilt cap in place. I added a safety cap across the AC line and added a fuse. I found a faucet washer that works well as a cushion between the cord and chassis. I took Reece's suggestion and spritzed the back with some water and placed it between two metal plates with a little weight for a few days. It came out real nice Just a little stain when there was already a break in the board. I'm going to try making a copy with some masonite. I cleaned all the contacts and oiled up the tuning capacitor. They're both playing really well now I hope Jody's white case makes it in one piece Last edited by bandersen; 12-01-2009 at 09:57 PM. |

Just a quick question,BobAndersen, Looking at the quote below and the picture... What is the value (mfd value) of the Safety cap and the type of cap (Caps from Justradios website)? I looks like you installed it from one side of the ac line just before the pilot light to chassis ground at that term strip. I just can't see if you used the chassis ground or another terminal on that strip.

I used an X2 type because it goes across the AC line. You might find this article on safety caps useful. The schematic I downloaded from Nostalgia Air shows a 0.04 uF. I chose a 0.047uF (or 0.05uF) as the closest available value. Sorry, i was never able to find the correct schematic for the 50B5 version. |

Re-cap on the recaps.
Hello,
Thanks. I'll have to put in an order for those X2 types. I thought you were adding the safety cap in addition to the existing cap to ground.. (C15 as I read it.. kinda hard to read). Did you have any problem prying off those little push clips that hold the dial pointer assembly in to the case? Sure don't want to break off those little "nubs" of Bakelite.

Replacement case has arrived
peverett (Jody) sent me this case to replace that broken brown one. It's in great condition aside from the flaking paint.
Any suggestions for stripping it off? I'll be repainting it white. Last edited by bandersen; 12-05-2009 at 12:03 AM. |

I have used various kinds of paint stripper on Bakelite, from gel types to old-fashioned zip strip. Some people also use oven cleaner. None of that stuff will faze Bakelite a bit, so use whatever you like.
Resist the temptation to scrape. Repeat: no scraping. If you're lucky, the original Bakelite will have been protected by paint all these years, and may still have that gorgeous shiny-new surface. If the old paint doesn't turn to mush and wipe off, be patient, apply more stripper, and come back later. I have stripped a couple of sets that looked so nice after stripping, I couldn't bring myself to paint them again. Here's one. Phil Nelson |

Thanks Phil, I give my favorite strippers a go. It does look pretty good where the paint already has flaked off which is going to leave me with your dilemma. Do I paint it ?
I've seen some wild color combinations online. I thought the only productions colors were bare bakelite and painted white ? Last edited by bandersen; 11-13-2014 at 02:44 PM. |

Pay no attention to the loons who paint old radios glitter green, popsicle purple, etc. They are going straight to Hell without passing Go.

Seriously though, I've been searching for example photos of several radios I picked up recently and have seen some really horrible restorations. Horribly overpriced too. Like this Philco 38-10 with it's photo-finish completely gone On sale for only $350 Anyway, the stripping has begun Last edited by bandersen; 12-06-2009 at 10:15 PM. |

I don't get the whole painting a radio wild colors thing. There was one guy on the radio forums who claimed he made good money doing this, but if it really is that easy to spraypaint a junker radio and turn a massive profit, then I think we would see more out there.

The weather has finally gotten warmer and I've been able to do some painting tests.
It turned out that the bakelite under that old paint was pretty rough so painting is really the only option. That's fine with me - I'd like a white one anyway. I used the old, cracked cabinet to test out some different products. I had a few disasters like using Watco clear gloss lacquer over Rustoleum specialty lacquer. The white lacquer immediately puckered and split I used two light coats of plastic primer, four light coats of white lacquer, applied the decal and three light coats of clear lacquer. (That's not where the decal really goes - this is just a test) There's some orange peel, but I think some wet sanding between coats will take care of that. Now it's finally time to try it out on the undamaged cabinet - Last edited by bandersen; 03-12-2010 at 01:35 AM. |
