Hi all,

I'm just starting to work on the Glencoe 1/74 scale Martin MB-2 biplane bomber. There's a great build-up article on the kit at the link below (just so you all know what I'm talking about):

http://www.crossandcockade.com/WNW/MB2.htm

Anyway, the wings are slightly warped. I've read a procedure for unwarping wings that involved heating the wings in hot water, and then taping them flat so they cool in a new, straight, position.

That's all well and good, but does anyone have the particulars? How hot should the water be? The wings are only a little warped, so would hot tap water be enough? I don't want to melt the wings.

Any advice would be welcome.

Regards,

Mr. Lawson is the man - what I bemember is as hot as the tap.
For the reason you said.
(meltie)

It's a buck-20+, anyway and that's gettin' up there.

Greetings all; Lufbery let me express caution here. Using hot water as a medium for straightening resin is safer that trying to straighten styrene with the same method.

Polystyrene reacts differently of course.
With polystyrene often just stressing the the warped part if it has a narrow profile like a single part wing wing will do the trick. Case in point the DML/Dragon Fok. D.VII. Wings that are split in two parts horizontally have to be done before assembly. The average tap or hot water furnace is set below 120 degrees to avoid scalding. Hold the part under running tap water and flexing the part can be done. Then press it to a flat surface as Barker suggested.

For the newer modeler. DO NOT drop the part into boiling water. Or you'll have to build a model that looks like it has cartwheeled.

Thanks, guys!

It sounds like I'll be able to get everything straightened out in short order.

Regards,
