Straighten wing; Help Required

Hi Guys,
Before I FUBAR this wing I'd like some help please. The wing is warped as I hope you can see. My plan is to immerse it in hot water (how hot and for how long ? ), then put it between two bits of wood and put a concrete block on it until it straightens out.
I would appreciate any advice or alternatives.
If all else fails I'll have to do a 'Marklo' on it and try and scratch build one. Might be interesting as I have never done this before. The wing is 29.5 cm long.

hey Joe why not try heating it with a hair dryer on the specific warped area and then just clamp that area between 2 small blocks of wood

Hi Joe, Thanks for the compliment.

As I understand it polystyrene needs to be heated then cooled to reshape it so apply heat, doesn't need to be that hot, afaik around 60 degrees C (which is the average pain threshold, so when it feels too hot to touch you're over 60 degrees) then work it a bit and rapidly cool it, ice water or even cold tap water is good, rinse and repeat until it's the shape you want.

If you were to scratch build a wing I'd be be a bit nervous of the span at 29 inches, I'd be inclined to reinforce it with some 1mm or 2mm brass rod to keep it straight.
