I was just wondering when mounting a trackball plate onto a wooden control panel do most people route out the panel and install the plate flush or just mount it on the top of the panel.
Well, I just mounted mine on top, which is rather common. This is the easiest way to do it, and plays fine.
If you are considering flush-mounting the plate, you might consider just routing out the bottom and foregoing the plate altogether, if you do it right that can look even better.
