Hey, how hard is it to install a regular old CTS or Alpha pot in a crybaby shell? I've got the gear and tooth thing.  I'm thinking i need one of those long shafted pots, cut the shaft to length, and somehow secure the gear to the shaft.  Just checking, it could be simple, could be a pain in the rear.

I considered this idea several months ago and rejected it. You are right you need a long shaft solid not split shaft. If you had to cut
the shaft to length you would probably destroy the pot in the process. You can get guitar pots that are long shaft, made for Les Pauls
mostly, but they cost almost as much as a wah pot. The gear is attached to the shaft with a spline which requires drilling a hole through the gear and the shaft, not an easy task even with a complete workshop like I have.   Also, the diameter of the shaft would have to almost exactly match the diameter of the opening in the gear.  I thought of using some sort of epoxy to attach the gear to the shaft, but decided that  I wouldn't trust that to hold up over time.  It would not be simple at all to do.  Wah pots are expensive, but I don't see another alternative IMO.

Cutting pot shafts is done all the time, with a little care can be done without harm to the pot.

The "long shaft" Les Paul pots are actually long bushing and wont help here as they have regular length shafts emerging from the long bushing part. (and they are split-shaft knurled)

Yeah pot shafts are easy to cut. Use a hacksaw, rotary tool, or if you're really worried about messing up the workings get yourself a mini pipe cutter from a hardware store. As for fitting the gear on the shaft, i always cut a "flat spot" on the shaft itself to make it more like a 'D' shaft then drilled the hole for the pin. Or, you could just slip the gear on and hold it there with some hardcore glue. I've used both methods in the past with good success.

I am curious as to what pots are being used, a linear taper is not great for a wah. As far as long shaft Les Paul pots, that is not true.
They are long shafts and you cut off the threaded bushing around it to reveal the shaft.  I did it and glued on a gear and it worked
fine but the standard audio taper was not great in a wah either. Goodrevdoc says he has good success gluing on the gear, how long
have you used that pot and want kind of use has it been subjected to?  Wah pots are subjected to such hard use relative to other
pots that are just used for volume or tone control, a moddified pot would have to be incredibly sturdy and the right taper to justify
the work involved versus buying a commercial wah pot, IMO.
