      I’m trying to remember whether we’ve had this conversation before…

      But just in case, the joystick assemblies out of a Futaba FP-T5FN R/C

      transmitter are perfect for building JS-1 repros.  They can frequently be

      found for cheap on ebay.  The case you want is a Hammond 1456FE1WHBU:

      I think DigiKey and Mouser sell them, I don’t recall which was cheaper.

      I never found good buttons, I used Radio Shack buttons with the smallest

      possible hole size so I can widen them out at some later date when I find

      good keyswitch buttons like the original.

         Agreed. I also have the Dazzler in my system and I recently acquired a D7+A card and I have a joystick core sitting around some where. I’m going to try to build a JS-1 and see if the card I have works.

            How did you machine the hole for the joystick and the pot adjustment slides? The joystick opening is about 1.5” in diameter and the adjustment slides are something like only 4mm wide. I’m figuring a nibbler and maybe a Dremel tool but I thought I’d ask before I started hacking at it.

            For the switch holes I purchased a 1/2” hole punch so I’ll get some nice clean holes with that.

            Thanks!

         



        While I haven't built a replica JS-1 yet, I have only my original JS-1, I use my dremel for many projects such as this. And with the right cutting wheel you can get the job done. They have cutting wheels which are thicker, I have 1/8". This would help in cutting a slot for the adjustment trimmers. You might have to improvise on the thickness of the slot if the cutting wheel doesn't match the trimmer knob by cutting slots incrementally till it's the right width. And use the radius of the cutting wheel to square off each end of the slot so it doesn't have that tapered look. You might need the flex shaft extension to cut the slot for the X trimmer since the distance from the edge can be longer than the dremel shaft.

        As for the joystick hole, don't they have a hole punch big enough for that ?
        That would be the quickest way out.
