No apology needed ...clarifications are MUCH better!

I will most definitely check out the book. I wish I was
more familiar with the airplane from an assembly pointbut,
I did not assemble this one. I didn't want to risk separating
the wing and started over out of risk of breaking the joiner
/ ribs or both. Now that's a trick I'd like to learn. With this wing being
secured with polyurethane glue, could anything safely soften it
as to take the wing apart?

Congrats on the (EF?) Yak 88...that's a sweet one! Yellow and black or clown colors? I love the
Yak 54e...the 88's baby brother![8D]
