Gluing cracked Wurlitzer knobs

[David68]

One of the control knobs on a 206A has three cracks in it.

Has anyone come up with a good way of fixing these so that the cracks don't open back up? Glues don't always hold that well to plastic, and I'm thinking it might need to be reinforced somehow. My grandfather was fond of using fiberglass cloth and epoxy.

That may work. I was going to say wrap strong thread around it dipped in epoxy. There is a kind of thread that can not be torn with your bare hands that is used in acoustic pianos. You should be able to get it at a craft store. I bought mine years ago and still have plenty, I do not remember which store I bought it from.

I was also thinking of getting a metal sleeve, like a length of brass tubing of the right size, and epoxying it around the outside. I'll have to check control panel hole clearances, but something of the right internal diameter can be ordered from McMaster.

Maybe cheaper and less trouble just buying a new knob at VV ?
