Did some more testing with the GoToStar (IDEA/iOptron) system on the Vixen Super Polaris mount.
With the custom bracket (made by Jeff) installed with the appropriate bolts I was able to place the GoToStar Dec motor in its proper position. Used the old flat plate (made by Tony) to hold the motor assembly to the Dec bracket.
I had screwed up in the bracket design by not accommodating for the ridges on the top of the motor casing. But it occurred to me that this was not a show-stopper. In fact, I wondered if it would prove useful.
I put rubber band pieces between the outboard part of the bracket and the motor to serve as something of a shock absorber. The motor assembly could move a bit for imperfections in the gears. The rubber strips, cut from a thick but small broccoli elastic, would act as a spring, pressing the gears together.
Boxed everything up. Used a recycled food container as a protective cover over the Declination motor assembly as I put the mount in the carrying case. That's until I can make (or print in 3D) a new custom cover.
