Hello,
I just completed sheeting my horizontal stab with 1/16th balsa over 1/4" balsa framing. I used yellow wood glue, and weighed it down with 60 lbs of weight. When I went to check it out later it has a slight bow to it. The work bench it perfectly flat. What would cause this, and how would you correct this. It's very disappointing that you think you have every perfect, and it doesn't come out that way. Thanks in advance.

Regards,

Pat

well sometime just laying it down on a flat surface with no weight can get rid of the bow.

If all fails just build another if its not too much trouble.

Try dampening the side that is on the inside of the curve, and weighing it down again. If that doesn't work, do it again, but place it so that the tips are up and the center is against the table. Then, take a piece of thin sheeting about 3" wide and as long (or longer then the chord of the stab, and weigh down the tips.

I am with MINNFLYER on this one. Use ammonia to dampen the wood. I would suggest though that you dampen BOTH SIDES. Just wetting the one side means that it is going to have to "STRETCH", but if you do both sides, the one side will still have to stretch, but not as much due to the other side compressing.
LET IT DRY COMPLETELY before removing from setup.
