Thanks, Aleem and Don...
Just a tiny update since I'm pretty excited it all worked. I got the other side on pretty easily (much more so than the other side) and the front top panels fit near perfectly. Super nice...
Now the daunting task of getting the rest of the top on since I'm not sure now to make it form correctly. Perhaps some tiny slices along the spine since it needs to be both curved around the formers and have a bowed spine...
I may need to practice on another piece of scrap!
Cheers,
Dan
