That's an interesting picture. I was trying to figure out why the worm pulley was so small, and then realized that that mount's tooth count explained it. :-)
I would think that selling DIY PMC8 kits for refurbing select mounts from other mfrs, could be a good idea, down the road. Perhaps someday move the motor counts out of the source code and into an external .xml file for both ASCOM and INDI, to facilitate?
