Burl, I could do that, but I am unsure if there would be any remedy, period. The warping is so slight, on one corner, it is actually hardly even noticeable, until you put on the lid, then it just doesn't fit very well.
I need several Imirie shims made for this season for feeding. So my Husband said that he would cut the super down into several shims, so it is not worth the bother of trying to fix it. So, I probably won't put the picture on the forum, this box has a great plan for its life, hee, hee. Thanks anyways, Burl, have a greatest of days. Cindi
