I'm looking at reproducing the entire joystick. It's been in the works for a while, but I still don't have the shafts back from fabbing yet. I'll post when I have them. The originals are metric threads, which is what I'm making also. They will be available with either a 1" or a 1.25" black ball. Anyone have a lead on the springs? I'd rather use an off the shelf spring if I can find one that's close.
Wow, that's awesome. I don't know about the springs, but again, maybe Sanwa has something? I didn't see anything that was very close at my local hardware store last time I checked.
If you can get the thread specs on the sanwa stick, or tell me where to get one, I'll see what i can do about making some allowing the sanwa balls to fit.
You can find Sanwa balltops at
LizardLickAmusements. There are also a couple different types of Sanwa springs there, as well as a Seimitsu spring. I mention Sanwa because they are a popular company (especially among the fighting game crowd) and they are Japanese like Nintendo. In fact, their JLF-TP-8T joystick uses the same mounting bolt pattern as a Nintendo joystick. BTW, the
Sanwa JLW-SP Spring looks similar to a Nintendo joystick spring in that it has the same number of coils (7), but I can't tell anything more about it just from looking.
However, if you plan on reproducing the Nintendo balltop, then compatibility with Sanwa balltops is not really necessary, except for people who want other balltop options (there are some fancy balltops for Sanwa joysticks).
