I'm moving on to installing the dome rotation motor system. I was just looking carefully at the parts in preparation for its installation and I have a question. The motor shaft has a slot and a key as I would expect to see. The mounting hub for the gear does not have a slot. Instead, there is a set screw and the set screw is slightly bigger than the slot. This setup doesn't look right to me. Has anyone dealt with this and if so, what did you do? In case it's not clear, the gear will not fit on the shaft at all if the key is in the slot. The key must be removed and set aside.
I could just tighten down the screw in the slot to secure the gear on the motor shaft. To me, this seems like something that will fail, perhaps even over and over again. The easiest thing I can think of doing is to slightly grind down the tip of the set screw so that it will reach down into the slot. I think this will work but wanted to see if anyone came up with a better idea.
