Warped Polymer Board

[Pounder]

I have a Tandy Polymer Cutting Board that for reasons unknown has warped. I have tried putting a weight on it to flatten but within a day it warps again. I am thinking of throwing the thing into the stove to heat it and hopefully flatten it to the original shape. Before I burn the house down does anyone have any thoughts on this plan, perhaps what temperature I should use? Money is tight so I don't really relish buying a new one.

Appreciate any advice you all can give.

The lowest setting for 25-30 minutes should work but you might want to screw it to a piece of plywood.

Hey Tree Reaper, again thanks for the input. Seems you are the only one that respond to my posts. You don't know how much I appreciate your direction in these things. Man, I am in your debt.

No problem, it's likely nobody else including myself has done it.

I have wet formed using the oven so I have a rough idea.

Check it at twenty minutes to see how warm it is and go from there.

I'm guessing 20-30 minutes but no more than 30.

Call your local Tandy and see if they will replace it for you. It shouldn't do that (as I'm sure you know).

Mine all do that after a while and it didn't matter here they came from. That is one of the problems with LDPE. If you are punching in the area the punch cuts will spread the board and eventually warp. Because LDPE is softer the edges go in deeper than HDPE. On the plus side, that saves your punch edges and at least for me, gives me a cleaner punch with one hit. Flipping the board over every so often helps. So does using the whole area, most punches tend to be on the center of the board and that make them warp faster. I haven't tried heating them to flatten, but it might work.

If you just left it screwed to plywood it would stay flat.
