Well done. This is exactly what I was looking for.

I've had good results with a heating pad. Less messy the trying deal with a bucket of hot water.

Beautiful. Thanks for sharing.

good video, thankyou for your knowledge.

That method looks good, but that's a LOT of hot water!!! Thanks for the idea!

True, a hot box is a bit less of a nuisance and cheaper to do.

Really nice 👍

Looks like there is a small amount of spring-back to straight. Likely not an issue as long as both sides of the wing halves are the same. I don't have access to the Depron branded foam sheets, but I suspect the ROSS brand poster board with the paper skins and a foam core is the same type. It sure does seem to have the same characteristics.

There's a lot of foam boards out there similar to Depron. As long as the foam is closed cell foam this technique will probably work. But you would obviously need to remove the paper first.

Nice work 👍

Is it perhaps an idea to do it differently? If you were to cut two ribs in a slightly more curved shape, And if you glue those ribs to the ends of the wing. You make a bed with wooden slats (also in the good shape) And you pour hot water IN the wing? It is / was just an idea... but maybe... that could be further expedited? Because yes, on the outside, that hot water does not touch! (Something has to be done for that!) (But hot water Does shrinks the materia!?)which is still well then !? friendly greetings from The Netherlands! Rob.

But if the wooden bed and ribs were to be glued to the wing, that would add weight without making anything easier.

this is exactly what i was looking for also. are there any issues with hysteresis? should you over bend to account for spring back?. Does the shape flatten over time?.

You will expect a little spring back so it's a matter of trial and error to get it right. but once depron is formed it doesn't flatten over time.

@@MicronWings umm.. ive built dozens of depron models.,not convinced as the ones ive built stay in shape for a while but they all deform due to flight stresses and those curved lose that curvature.

how can I bend a wing bigger tnan 1000mm wingspand and more than 300mm chord length?

For larger wings for which you can't make a big enough template as i have shown here, you will need to use heat to bend the wing. Either very hot water or a heat gun are best. But it's a bit difficult to get consistant results with these methods.

I would employ a hot box, which would be little more than a plywood box of the proper size that is insulated to hold the heat from heat lamps. Heat lamps are fairly easy to come by since they use them to keep baby chicks and other animals warm. Once the foam is up to temperature, turn off the lamps and let everything cool off.

Have you tried heat gun - hot air?

Heat gen is very hit and miss. You need to get an even heat all over, but it is possible and I've seen some people have success with it.

Il depron assorbe l' acqua 😂🤣🤣
