I want to build a pendant style jog control for my router and wondered if anyone had any ideas or parts.

Just want a simple jog control to jog machine, switch between axis's and change jog mode as setting jobs up using the keyboard is getting a pain in the arse.

Would like a rotary style mpg as found on cnc mills/lathes etc not joystick type as I have looked around and seen people using xbox controllers etc but not really what I want.

I could make the housing for it but need all the bits to go in it, any ideas anyone??
