[TR] TR3A Switch Knobs

[terryrs at comcast.net]

I have the original switches in my TR3A.B  Issue I have is the way the
original knobs were attached to the switches by this kind of spring thingie.



Heh heh....B  Bet I have the List engineers tingling on THAT term, eh!!!!!



Anyway, you know what I mean (I hope).



So...during the restoration several years ago, the old switches' spring knob
holders were shot, so I drilled completely through the new replacement knobs,
tapped the holes in the switch shafts, and installed dinky inset allen screws
to hold the knobs onto the switches.



Worked fine until I pulled the control panel out again this winter, and had to
literally smash the knobs to get them off.



What would be a betterB long term solution?B  I'm thinking replacement knobs
with built in inset screws to clamp onto the shaft.B  Anybody know where to
source these?B  ...Or, is there a way to replace those spring thingies that go
on the shaft?



Hopelessly inadequate as an engineer,
