Warps induced to be straight sometimes come back to haunt you. Redo it-you'll be happier.

Will acetone (or CA disbonder) break the bond easily? If so, I'd remove it and glue it back.

yeah debonder removed it. It still seemed a little warped. Have it pinned down and glued back on now. Will let it sit for a while then see how it is.

The LE doesn't rest flush with the board so that is why I picked it up. Just used some scraps under it this time to hold it up.

Removed the LE and glued back on. Helped a little. Got to glue some aluminumum tubing in and a couple other knick knacks then I can work on the bottom wing.

I'm pretty sure once the wing is covered and attached to the bottom wing the slight warp should be gone. It is pretty light anyway.

Thanks! I haven't been on it in a while. Adding an extra workbench today so hopefully I can get back on it this week.

Making "Bows": Make a bending forms out of shipping carton or foam board. Cover edges smoothly with masking tape. Soak weighted-down balsa strips in bathtub for a number of hours. CYA ends of two strips together about 1/2 inch. Tape end to form. Pull inner strip around form and tape at other end. Apply Elmer's wood glue to inner strip and pull outer strip around inner strip and tape to end of form. Let dry completely. You could use CYA to speed things up but it's nasty to work with, sticks to fingers, hard to sand smooth. If you crack, but not break balsa strip, "cheat" and finsh joining or start over. When repairing "munched" wing tip bows, I usually cheat and make standard wing tip sections from sheet balsa. Practice makes nearly perfect.
Laminated balsa and glue are quite sturdy.

Holy return from the dead thread batman!

I've still been working on it slowly. Actually been flying a LOT so this has taken a back seat. Picked up a Top Flite p-47 GS kit and want to start that soon so need to get somewhere with this one.

Got the bottom wing done and glued in some tubing to hold the wing.

Soldering and bending the struts for the wings. I decided to wrap them with copper wire then solder. Probably overkill but don't mind

Got the motor mounted. Not correct prop in photo though. It looks like it will be a little short so will have to extend it a little. Will see when I start on the cowl and engine.

Pat's wings are built very light, and you have to be super careful. I build them pinned down flat on the building board. Pat likes to use Microlite to cover his models with, and then will create the wingtip washout using the microlite on a jig. I don't like doing it that way because Microlite needs to be periodically re-shrunk. It develops wrinkles and loses it's shape over time because it's so light. So I usually warp the wingtips into washout over steam and then cover it.

But yes, build his wings pinned down absolutely flat on the building board. Also, he has an article out on aligning biplane wings in an old issue of Flying Models magazine. Do you have that? If not, maybe I can find it and scan it for you. Also, you can always write to him. He is very eager to help.

Sorry...looks like I didn't read all the way to the end of the thread. You've already got your wings built. Nice job!

Haha yeah they are already built. Always like tips though!

I'm using econolite or whatever it's called. Similar stuff I imagine. My wing built with washout but as you said it's so light it may be washed out the other way because of the heat we had. Just not sure about these small light planes. All my planes coming up after this will be a lot bigger.

But I have learned a lot from doing it! Since the parts I'm covering now I learned to use less CA Impossible to sand when it wicked everywhere. As I went on I used less.
