I recently purchased an STi project and trucked it from North Dakota to Texas. Several ribs that were installed in the rudder and vertical stabilizer have warped or buckled due, I think, to the increased temperature and humidity here in Texas.

Any suggestions on how to straighten in place? I was thinking of cross-cutting, straightening, adding a stiffener, and then using Hysol to bond the stiffener and splice the cut.

I'd heat and remove the Hysol on the small end and see if you can move it just far enough away from the framework to Dremel it out. Had to do the same thing on the secondhand kit we purchased.

Maybe a series of pieces laid flat in the center of each rib, and glued from one rib to the next to hold them all rigid side to side. JImChuk

Sounds like a good plan. I'll give it a try. Thanks!!
