Ka Knobs

[<slowboy@cox.net>]

As we all know, the knobs tend to crack.

Besides replacing with new, what is the best way to fix the crack? Is super 
glue the only fix?

I thought about buying new and still may, but right now I am drilling out the 
threads on one knob to widen the hole for a different switch and then use a set 
screw. So far it's looks good except for the crack.

Thanks!
