Guys, thanks a lot for numerous tips on using the slip ring. I may give the "fuse" approach a try because putting the
TK22 board in the turret saves a lot of space.

Dan, about the fuse, I see from your photo that those are ATM fuse correct? I found an in-line fuse holder on Amazon:

My idea is to group 3 2-amp slip ring wires together and solder them to the holder. Is this gonna work (and safe) ?
