Thanks, I have been trying to tape them as they fit but as they change shape again I find I am useing a lot more tape until I completely lose what I was working on.
Now this is before I start shaping the pieces, just getting rid of the gaps. I have done a few, quite a few, and now I am just venting. Believe it or now, I am happy most of the time with the results. If not, no one sees it. The idea of a touch of glue as they fit seems like a good idea. I was also thinking rubber or even hot glue during the fitting stages.
As I finish shaping them, the final step before finish, every thing usually fits.
