I mounted an old style pacman stick on a wooden panel. I cut a square hole, dropped the joystick in and then used a piece of sheet metal, I think it was 16 gauge over the top of the whole panel and then put a piece of lexan glass over the top. Oh yeah, since the style of the stick has a wing like over lap, I routerded my wood in those areas so the stick was flush with the wood. If this doesn't make sense, let me know, I'm a little burnt out from work!
Good luck to you!
