Default mechanical coil switching of two coils`

Hey Ross:

I would think outside the box, forget a mechanical arrangement, use
the In line ganged to control relay switching.

And if you really want to go mechanical for some strange reason I'd
use a flex shaft. Bend a flex shaft 180 degress and viola'.
I too have thought about this very topic, for my amp I might try pin
diodes since I'm a not using GG.

eluding me- I would like to use a single rotary switch to select taps
on two different coils. In-line ganged switching would be inconvenient
for my layout. Is it possible to homebrew a mechanical linkage to turn
two switches? I have a front panel and metal deck (vacuum tube
construction style), so I could mount gears and cams and stuff, and my
layout does have a good clear space between the coils, so there is
room. My problem is that I have never read anything about doing this
and don't know where to begin looking for parts, etc. Again, I have
two coils with four taps each for 40, 20, 15, 10m.

Thank you very much for any thoughts on this matter.
