Joystick Grommet (Real Identity)
Stormy151:
Is it possible to clamp the steel insert so that it can be drilled without "twisting" the rubber? A metal clamp of some type may also act as a sort of heat sink...
Just an idea.
Tailgunner:
Interesting thread. I for one would have no problem believing Wico had their plateforms made to their specs, when you're talking about ordering several thousand pieces, companies are more than willing to work with you on filling a preticular need.
As far as drilling these alternates out, the best I can think of would be to make a jig up to mount them in a metal lathe. It'd be a hollow round or hex shaped piece with the mounting screw holes drilled into it. the plate form would be screwed into place and the jig would then be chucked up to drill out the metal insert. Since heat is a problem you'd need to keep a coolant flow on the drill bit, but by stepping up the hole size and drilling slowly you could probably manage on a dry lathe.

UPDATE
OK it is confirmed and I have part numbers. A certain arcade company has purchased these in the last two years in large quantities (thousands) and they purchased stock sizes. The two units they purchased matched the different size plates in joystics so they must be drilling them out.
I don't know if they should have given me that info so let's just say the company was somewhere between nearway and farway.
The part numbers were150P-18 and 200P-45. Again I repeat they did not order custom parts although I don't know why at those quantities.
I hope you have some luck with the machining Randy. At least we have some information which will get us the right load rating on the parts.

Hehe. I must be getting slow. That took me a minute.....
Keep in mind that drilling to those specs is easy. I opened them up enough on the first pass to accomodate that company's sticks with no problem.

Thanks for getting the extra info and confirming the speculations. I still think it's doable, but special jigging and coolant flooding will be in order.
BTW, there is virtually no way to clamp onto the metal part of these, so the fixture has to take that into account (which is why I haven't gotten around to building it yet.) I will try to have at it again this weekend.

this might not work but... What if you take a drill bit that's the size you want to go to and turn the tip down on a lathe to match the smaller size.
