Hmm, yeah I guess I can see how stack just two sheets of 1/8" balsa would be kind of a pain. Still, I think I will try, just so I can make sure each part is identical to its counterpart.
No pain to it. Try a little double stick scotch tape to hold the sheets together. Heck, I use it to put the traced paper templates on too. When you place the tape, make sure it'll hit each piece you cut so they'll still be stuck together when you sand them.
