Sneak Preview: New Trackball from Ultimarc
padstack:
Ultimarc Clean-mount?
Ultimarc EZ mount
Ultimarc Supermount?
Ultimount?
Those would be my guesses.
Nice work!
It appears to me that you could probably just use a hole-saw and a few counter-sunk screws and be set. Looks cool to me!

What would seal the deal for me on this is if the trackball had some sort of flange for the top of the panel. For instance, you could rough cut a hole for it and not worry about being an absolute perfect circle as it requires now. Then you mount the trackball, and from the top screw down a flange type connection like what is on a push button housing. This covers any errors in the cutout, and would give the TB an ultra smooth and pretty tie in to the CP.
As to name, I prefer Ultimarc E-Z Mount Trackball. Simple, and to the point.

OK here is the optional flange...
Its a 3 inch trackball by the way, rather larger than a button! The appearance when mounted is exactly the same as the Happ from the top of the panel (without the mounting plate!).

Neat Idea Andy..... At first I thought you'd just had a new top injection molded to fit the betson, but then I realised that you'd have to make the mechanics of it fit higer in the bottom case as well.... Very good! Not sure how the encoder wheels fit unless they are somehow geared from the rollers. Do they still spin well with the additional friction??

There is no gearing. The wheels just fit. It was a very careful piece of CAD followed by laser prototyping. The mechanics are fairly conventional although I searched for the best bearings which are not pre-packed with thick grease and also specified precision-ground stainless steel rollers.
I was also able to maintain the distance between the points where the rollers contact the ball.. just. This avoids the ball jumping off the rollers, something which was noticeable in an early design which pushed the rollers inwards.
Some good name suggestions here! Keep them coming. I already have a couple on here earmarked! The final decision will be made by a specially-convened committee... ok some mates down the pub...
