Thanks to all for your suggestions! At first I was going to buzz the
top off and make a metal clamshell top. Spent a few weeks designing
the top and making sure everything fit inside ok. Actually had
something that looked really good. However, upon reflection, and the
fact that I don't have unlimited time and money, I think I'll just
repair what I've got now.

Will let you know how it goes!
