ChuckI, I used the 3M sytrofoam adhesive. I simple sprayed both surfaces, waited a few seconds and put the two sides together. I then applied weight and then let sit for a while. I found the Dave Browns Southern Sorgham works much better (sorry 3M) and would recomend using that instead of the spray. I just feel better about the bond.

Meanwhile, apart from rebuilding the top of the tail sections, progress is slow, but sure.
