Happy Memorial Day Weekend Everyone!

It comes time for me to build another roll-to-electric device for a
friend of mine who wants to play his rolls on a standard direct-electric
pipe chest.  So the conversion from rolls to electric is what he asked
me for.  I have built these in the past, but it's been a while.

I thought that, before I got started, I would pose the question to all
of you as to what you have made and have found to be reliable.  I have
seen designs ranging from just pouch boards with contacts like Estey
used to the Wicks style with an actual pneumatic with key contacts on
it, also like in converted Wurlitzer relays.

Thanks for your help.  Photos would be great too, if you have some.
