Typewriter Platen Roller Knob Handle Broken ! Repaired, Mended, Fixed, Melded, as good as Replacing

[@babsstevetillett600]

This method has proved to be a very handy thing to know. I’ve used it to repair knobs for typewriters and other plastic parts. Thanks for spreading the word about “melding “

The key here is to heat the metal sufficiently above the melting point of the plastic that it can sink into it without burning it and also without it going through, If you go too deep, you just cut a hole in the plastic with the ring and now you've made yourself a much bigger problem. So a single loop of a key ring is probably better. Thin, but still metal and enough to give extra support to the bond. Temperature, depending on the plastic, is probably 50 degrees F above the melting point. So that when you get it in there, it sets pretty quickly around the reinforcing ring. For many such things, clear epoxy may be the better choice. After all, if it breaks again, you can use a dental pick to remove the old epoxy and then try a new method.

First time I have seen this...great idea to add strength. Going to try this on next broken knob. Thanks so much for making these videos.

Clever reinforcement! I was thinking of pooling some epoxy inside, but metal should be much stronger.

Epoxy alone might not hold it well enough. One method would be to stick short pieces of wire into the plastic, then pour the epoxy over.

First! I was looking for a way to mend plastics. Thank you very much. 😊

My 1950s Remingtons have a distinctive aroma which I like. Maybe old grease and eraser shavings, one of them I pulled a lot of eraser shavings out.

Such useful knowledge

great vids!

Never seen that before, makes sense, I'd epoxy it, just because I'm half German and need to over engineer it❤

JB Weld!
