In that example it looks like the ball isn't high enough. Is that just a bad pic?
That pic is at a not-so-great angle for depth perception.
- Degenatron's panel is 12mm (1/2"), same thickness as the removed upper cover.
- Moving the threaded inserts to the side like the "Under mount (support blocks)" method increases how high you can mount the trackball.
Two related approaches using a router if you want your trackball to ride higher.
1. Case top not removed -- case top provides support for the thin part of the control panel
- Route a pocket for the case.
- Route clearance for the catches on the side of the case.
- Use threaded inserts and bars/straps like the "Under mount (support blocks)" method mentioned above.
2. Case top removed
- Route a pocket for the lower case.
- Route an extra 2mm deep clearance slot for each of the two encoder wheels.
- Use threaded inserts and bars/straps like the "Under mount (support blocks)" method mentioned above.
