Hey folks,

I started dry-fitting some landraider parts together tonight and found that one part is badly warped on one side.



These are two shots of the same part. As you can see the lower one is distinctly bent out of shape. This isn't a resin part, (I kinda expect large resin parts to warp) this is directly from the standard GW Landraider kit.

Any ideas how to fix this ? will heating it in warm water work like it does for resin ? I could glue it and hold it down but it would take quite a bit of pressure and I'd be afraid the glue couldn't hold.

Heat it up and then start bending it. Injection plastic is more malluable then resin, so it should actually be easier.

Land Raider and that kind of injection plastic kit are made of polystyrene which gets soft at about 95 degrees centigrade. (The exact physical properties are on Wikipedia.)

You can easily get this temperature with either a pan of boiling water or the steam from the spout of a kettle.

Be very careful how you hold the part as you can get very badly burned by boiling water or steam. Long tweezers are best, and gloves or a tea-towel to protect your hands.

Dip the part in the water or hold it in the steam for a few seconds then try to bend it gently. By trial and error you will get the feel of how long the part needs to be heated. The timing depends partly on how thick the part it.

Practice on waste sprue before you work on your actual part.

Once it's bent to the right shape it will cool and harden quickly under the cold tap.

Oh, and use a hammer to temper it... right?

This part of the land raider gets fit into a "gap". It will stay in place, no matter if you fix it first or just glue it as is.

I think killkrazy tips are fine, may be not easy to apply the correct temperature.
You may use either water or air to heathen plastics.

No. You do not need to use a hammer. At all.

As noted, it softens at around 95*C. Steam or boiling water. Allow to soften, bend back into shape and either allow to cool by itself, or dunk it in cold water to set it quicker.
