Antique Radios found in Auction site or flea market are hardly maintain their original exterior. Especially tuning or volume knobs often would have been lost. Such radios lacking some parts often trade cheaply. So if you don't strictly stick to originality, you can restore complete receiver economically.

Step 1: ingredients

Plarepair(TM)(Plastic repair kit) is one of resin casting kit, same as "Super-bond" that is popular for dentists.

This time we are going to use these ingredients:

1) Plarepair (TM) powder (black)
This is 100% acrylic powder.

2) Plarepair(TM) liquid
This is Methyl methacrylate

3) "moulage you" (型取り君›). mold plastics
It is low temperature deforming material, a kind of polyethylene resin.

3) Another old radio's knob for a prototype

4) A new general-purpose knob
It should be about 5mm smaller than prototype knob, and the hole diameter must be match the shaft of VR or rotary switch.

You can buy Plarepair here. And perhaps there are other products similar to it in your country.

<p>Love this idea, and you're correct about if you are not a stickler about <br> getting original (read VERY expensive) replacement parts it keeps the <br>who restoration effort in saner territories. Just one other suggestion <br> - polymer clay. It's cheap, ready to mold or hand craft to match other <br> knobs, and can take on almost any color of finish (something I'm sure <br>many Steam Punker types already know about). And there is a lot of info <br> out there on how to make this stuff resemble almost anything. Just <br>whip it up and bake it (but test the plastic parts for this first - and <br>maybe use metal knobs as the base). Got a few projects myself to test this out on, maybe an 'iable or two waiting to be written?</p>
awesome. simple but so effective.
I especially liked your weathering detail. Brilliant. <br>Thank you. <br>r
lol looks easy
Very nicely done and you've solved a big problem among collectors.
Good work! It looks nice.
