Anyone know how to open this gauge?

I fashioned some quirky mounts using MDF for the motors themselves and hot-glued them to the internal structure. (although a 3D printer might be better suited. :-) )

Attaching the shafts was a little tricky but I ended up using heat-shrink tubing with a dab of rubber cement on the shafts to prevent slipping. This allowed for slight misalignment between the stepper shaft and the needle shaft.

Here is a shot of the guts of the gauge that Ray is talking about...

Paul, thanks for the info. Will try with two stepper first but i know when to contact if that plan dont come through.

Bob, Ray, thanks a million! Now i know they will fit and i will try to replicate this solution. That was the same setup i had in mind! Thanks
