Yesterday I had to do some workshop cleaning. I rolled my building cabinet outside in the sun. The wing was shimmed, weighed and clamped. Later in the day I measured and found I was now 3/64" off. Looking better.

HighPlains, I do have sheer webs glued to front of spars. Just not visible in photo. I will take your advice and secure wing n add the rear webs. This will make it a box spar. I keep the wing weighed and clamped so maybe the last little bit will work out. Then I will keep it flat. Thanks for the tip.

I had a good supply of old lawn mower blades 1/4 x 2.5" off a 6' mower deck. I cut these into different sizes. They make good weights for model building IMO. I just need to paint them as they are showing signs of rust. May add some glue on felt to bottom.
