[R-390] How are your knobs ?

[Barry]

Charles,

You're correct about the CA.  I was thinking epoxy and forgot the OP mentioned CA.  I'm with you, though.  I'd tend to go with epoxy in this application.

Thinking about this entire thread, I'm curious as to the strength of such a repair.  While the original center spindle has held up pretty well, a repair like this seems like a weak way to approach it.

It would seem to me that one could machine a slug large enough to fit in the skirt of the old knob - hollowed out such that an original-like set of fingers that would accommodate the original-style clamp would rise from the center (hope I'm explaining that well enough).  It would require some time/expertise on a lathe, but if someone had those resources (sure wish I still access to a good machine shop - sigh...) it could be done.  Epoxying (or other glue) on the large inner surface of the skirt would be a much stronger mechanical arrangement.
