you may want to try a metal tube that is heated up different sizes hold against it for a few seconds - you will have to brainstorm on best way to get it hot - possibly a heat gun and you will a perfect bend or curve in the wood / wear oven mits

As you wet one side that side expands as it absorbs the moisture. So the wet side grows longer. Window cleaners like Windex contain both Alcohol and Amonia, great for the modeler’s bench for many uses. I also use it for both Silkspan and Silk when covering. Over time the fibers in the wood do relax and the stress lessens. Just make sure it glued well and there are plenty of formers under the wood. Great job

I use rubber bands instead of the scotch tape; if the wood doesn't fit the precise curvature initially, it will bend a tad more as the fluid soaks in.

Two things I'd like to comment on, 1) Molding the wood before gluing the piece on like your doing is absolutely the correct method. Too many times I see instructions where they ask you to glue down one edge then wet the wood and bend it into shape while gluing it down. Only to see a "starved horse" look in the balsa after it has dried. Wetting the wood also expands it. It then shrinks back up when it dries. So if you glue it down in the wet condition, it will shrink between the unsupported sections, like ribs on a wing or bulkheads on a fuse, when it dries. Like plastic covering would when you shrink it up. So kudos to you for showing the right way to do it! Mold, let dry fully, then glue it on. 2) Whoever told you Ammonia weakens the balsa is complete bullshit. Especially when using Windex or the cleaner you are using as the amount of Ammonia is negligible. It might make a bad day for germs but that's about it. I've been using this method for nigh on 30years now and I have NEVER experienced "weakened balsa". In fact, before the internet, no one batted a single eye for using this method. Post internet, and morons just have to insert their 2cent opinion. Maybe they didn't get enough attention as children. In any case, soaking in plain hot water works well too if anyone is worried about it. In full scale, we steam soak spruce lengths and it bends around forms like paper.

A good video. I started with ammonia then quickly switched Windex. Now I use ordinary white vinegar which I find more pleasant to use. you can use it to form medium balsa at 90degrees to the grain I recently made a couple of Nacelles 50mm diameter 30mm long out of 2mm balsa with the grain going around the circumference and the joint butt glued. after they had dried they cut to fit the wing mounts there doesn't seem to be any loss of strength in the material, but it is a static model not subject to vibration or handling

NNNooooo any type of cleaner will restrict any adhesive/glue that you will be using to attach the sheet to the model's framework! Just use a small amount of clean hot water or steam will do the job for you along with a preassembled jig to keep it to the shape till it dries! Keep it simple stupid is the best rule of thumb when it come to craft modeling!

Hi there, do you need to fill in the wing? It will add weight and could affect how it flies. Can it not be covered leaving the open areas. If you did want to sill it in you could CG balsa into the gaps easy enough, just as you would do normal sheeting

Thank you Mark! Great video and looks much easier than soaking in water and waiting for everything to settle back into shape. As far as people worrying about loss of strength You could coat the balsa with epoxy mixed with some denatured alcohol making it almost the viscosity of water. The wood soaks it up and presto, added strength. Cheers!

Good luck with the sheeting, do you have the top and bottom waste piece of foam from when you cut the wing, if so use them either side of the wing to hold the balsa in place, with weights on, as they will obviously have the perfect profile
