I am building the 3 piece wing, adnd noticed a discrepency on the fullsize wing rib plan. Obviously, the rib plan is for a 1 inch rib. Whatareyou guys doing about the 1/4 inch discrepency? It would appear that thethrust load at the back of the spar (from the compression load) shouldbe transferred to the main spar. Are you enlarging (lengthening) the two cross members to do this? ordoes it matter?I am getting more confused than ever about the type of glue to use inthe wing structure. I like the T-88, but they sy it softens above150degrees. Any comments would be appreciated.________________________________________________________________________________

If I were building the 3/4" spar I would reposisition the center braces to make up the difference. IE leave the front face of the front spar and the rear face of the rear spare in the same place. Another option and one that I would probably opt for is making a 1" cap top and bottom to bring the dementions back to 1". Maybe there are other opinions.Stevee.BTW I used aerolite and Weldwood plastic resin. And probably would again.________________________________________________________________________________

Any opinion with the Tite Bond II water proof? The factory is Benjamin(something) Products.

>Hold On!! Y'all are working too hard at this!Per Charlie Rubeck in his excellent rib building forums, all you have to dois glue a strip of 1/8" ply to each spar (1/2" wide by the heighth of thespar) where each rib would normally meet it. These fill up the gap to keepthe spars in the correct position relative to the cg and center of pressure,etc. At least this is what I am doing and it is no problem.Hope this helps.John________________________________________________________________________________
