Which mounting plate did you get?

There are two types.
One uses 8 mounting holes, with exposed carriage bolt heads.
The other has 8 studs the back that go through the CP, and have nuts on the back side.

Both mount similarly.
You cut a big square hole for the trackball to go through, drill 4 small holes for the mounting bolts, and then rout the plate flush with the top of your CP.
You don't have to rout the plate flush, but it looks better than having the plate sitting on top of the CP.

In the end, you have 4 bolts that hold the trackball to the mounting plate, and four more that hold the mounting plate to the CP.
xcalibur:
Tha mounting plate has 4 'inner' threads for the trackball to mount to. It has 4 'outter threads for the bolts to connect it to the CP.

I believe this is the correct diagram from happ's:


Looking at this picture, it seems I won't have to cut that weird-shaped hole in the CP, just a square... seems easy.

I have the same laminate on 5/8" MDF.

I cut the funky shaped diamond hole using a drill to make a starting point and then a jigsaw to cut it. You could cut a larger square but I think having the diamond shape makes for a snug fit, increases the amount of wood you have between edge of 2 of the screw holes/trackball hole, and decreases the shock/potential shifting to the whole mounting plate and unit.

I did not mess with routing anything so mounting plate would flush at top, ie: recessed to be level with laminate.

Looks good tome and has worked without issue for quite some time.

One word of caution, measure twice, cut once.

That makes sense... Well, at least this will give me something to do this Saturday while my wife goes to her baby shower...
