Installing a 3" USB Happ Trackball: do I *have* to use the special mount plate?

(1/6) > >>

ARTIFACT:
do I *have* to order and use a "trackball mount plate" to install the 3" Happ trackball on my 3/4" plywood CP?

Is there a way for me to mount it under, by using a router to inset, and use screws from the top (like the joysticks but with an inset under)?

the way I see it, the ball comes out but only screws are visible on the CP top ... I've seen pics of that done here - but I want to double check

Thanks!

vidmouse:
Right or wrong, that's how I did it.
I don't find any problems using it or playing
stuff like Golden Tee.  One thing I might do
differently is use flat screws vs round but
I can change it later after a trip to the hw store.

There's more info and photos on my trackball

Thanks vidmouse

I plan to order an adhesive-backed CPO from mamemarquees.com and add a plexiglass sheet on top.

severdhed:
i did the same thing with my 3" wico trackball and it worked fine.  If done it in two different panels.  the first one was covered in colored plexiglass that was opaque.  i cut out the wood entirely for that one and bolted the trackball just through the plexi, that worked just fine.  when i did my second panel, i didnt cover it with plexi, so i routed out from behind all but about 3/16" and that also worked just fine. you dont need a mounting plate.

that sounds like something I can do - thanks

I think I'll order the mount anyway... I am ordering from Divemaster and it's only an extra ~$10.99 which is not much in the scheme of things.

goood to know it's possible without.
