Ok, done. Cleaned with the acetone and did a few small applications to build it up some. Seems pretty rock solid, so much more than epoxy. I ran the screw in to see if there was any flexing but there wasn't. Once the screw was in a little ways I noticed a small crack in the screw tower so I fixed that.
The Q-Bond is a bit pricey at $30 but I didn't use very much of the black powder so I have plenty left for other projects.
The before pic was in a prior post with two pieces shown. Here's the after. Not pretty but it doesn't have to be. Thanks for the recommendation!
