Replacement Mounting plates for Ultimarc Joys
<< < (3/5) > >>
ArcadEd:
Yeah, I probably can't do that.  I don't have a plasma cutter, so I need to make these out of aluminum which I can cut with my CNC router.

My point is that I can't weld to aluminum to make the bolts from underneath.  I guess I could make a through hole, thread it and screw in an allthread flush with the top.  But with only 1/16 aluminum I don't think there would be enough threads to do much good.  I'll put some thought into it though.

Tahnok:
Trackball mounting plate bolts are not welded on to the bottom, they are through. Mess with a trackball plate enough and the bolts will start to come loose and show on the top. They seem to be unthreaded, only held in by the coating.
ArcadEd:
Well I whipped up one over the weekend just to see how easy it was.  It was a bit more work than I thought, getting the aluminum all cleaned up afterwards, but still not bad.

Here are a few pictures.

Looks great, except those bolts. The bolts sticking out like that will make it difficult to mount under a CP. Surely there's a way to countersink them.

Also, are you using the original bolts that came with the joy? If not, it seems like you could save a little per-unit cost and not include them. The bolts that come with them can be countersunk fairly easily too.
ArcadEd:
Yeah, those are the screws that came with joys.  I did counter sink the holes, I just didn't countersink them big enough, so that will be fixed ;).

You can barely see the counter sink the plate picture.
