I needed to get the holes cut in the inner dome today, so I started out by drawing/tracing the inner dome hole locations.
I used the previous plunge and rotate method with the Dremel to cut the holes, and then I used a wine bottle wrapped in sand paper to smooth the circular holes.
Four year old Joshua loves to watch and help build R2 when he can, so I lifted him up on the work bench and gave him a sander. He did a GREAT job!
Finally, all the inner dome holes are cut!
