I haven't been able to get to my friend's wood shop, so I returned to my Star Wars yoke, & picked up where I left off, so long, long ago...
Much, much thanks to PL1 and the very thoroughly documented 'How to Build a KADESTICK Yoke Interface':
http://forum.arcadecontrols.com/index.php/topic,134781.msg1542677.html#msg1542677. I am following the instructions to the letter.
I'm not crazy about my soldering. The last couple of connections came out pretty good, but the rest are sloppy as hell. I'm getting better at it.
For absolute newbs, like me, a couple of warnings that the even vaguely experienced will laugh their heads off at: 1: If you haven't done any soldering in a long time, do some practice work on some scrap board 1st. 2: Don't solder late at night, when you're tired.
If you try lead free solder, which is what I use, some advice (again, for newbs). Lead free needs more heat & more time to melt & flow. Be patient. Use flux meant for lead free--its designed to take the extra heat.
Also, for those who really, really want to keep their soldering tips clean, I have a suggestion that I actually don't recommend. Get a block of Sal Ammoniac. Here's a link with info about it:
https://en.wikipedia.org/wiki/Salammoniac. To use it, heat your iron, then drill the tip into the sal ammoniac. Add solder. The tip you'll get will be cleaner than when it was brand new. But WEAR A BREATHING FILTER when you do this. The fumes off this stuff are toxic.
Another thing for newbs: The '3 handed tool'. It has 3 alligator clips for holding parts or wire while you work. Useful, but beware the teeth on those clips. I had to thoroughly wrap mine in electrical tape to stop them from biting through the insulation on the wire. Another useful tool is a tiny vise, which I purchased from a 'Warhammer' store. It's intended to hold miniature figures for painting, but lends itself well to this work.
