Frame Gouging for Dome Drive, One More Dome Drive Bar Modification

Well, the fit of the dome drive bar looked good on the frame by itself, but once I added the motor, motor mount screws, etc., it turned out that one of the ribs I added to help support the back door slightly interfered with the fit.

I turned everything upside down so I could better inspect what needed to be cleared.

Rather than saw down the bar some more, I used the Dremel drum sander to remove just a little material from the back of this rib.

That's better.

Next, I returned to the dome drive bar. Earlier, I had pronounced it done. That pretty much guaranteed that I had a little more work to do.

It would have been done had I decided to do things like I did with droid #1. On droid #1, I attached the 3/4" diameter shaft adapter above the dome drive bar. On droid #2, I decided that I want the shaft adapter to fit more snugly onto the motor shaft, so I needed to clear out enough space for the shaft adapter to fit in the center of the three mounting holes. I decided to hack away with a 1/2" drill bit to clear more material.

I may not be able to start a fire with a couple of sticks and some leaves, but I'll bet I could start one with a drill press, steel, and some wood underneath.

Some areas required a file to remove excess material.

Time for a test fit. The left side of the shaft adapter clears...

... as does the right.

I may need to shorten the shaft adapter a little bit. After that, I'll JB Weld the shaft adapter to the motor, and then drill and pin it to the shaft.
