I have just received my first laser cut wood pack. It was ordered from the FMS/Doolittle Media site and looks great! It's for a BE2e at 80 inch wingspan.

Some of the edges of the ply parts are a bit sticky - I guess from vapourised glue from the ply condensing on the edges of the wood. There is obviously a burn mark on all the cut edges of the ply and balsa parts too.

So, what does one do about the sticky bits - wipe with alcohol perhaps? - and is it best to gently sand off some of the carbonised wood too to help with adhesion before applying PVA?

Thanks for your thoughts.
