Reaper was a big help today! He worked hard at playing Star Wars Bounty Hunter instead of taking pictures. LOL
I filed some more on the dome with a smaller file to get into the places the other file could not.
I then glued the outer trim piece on my R4 dome and let it dry for an hour.
I test fitted the ring on my lazy susan and everything looks grand.
Now I just have to figure out how to glue the lampshade part together in a way that I would not have to hold it for 3 hours while it drys.
