Last year I made a bunch of med supers with thin surplus starter strips for cut comb sales. I ended up with quite a few frames that were either to thick, odd shaped, uncapped, to dark or partcially drawn out. I ran these in my 30 frame extractor along with the rest. I used a hot knife to uncap. I started as slow as i could go at first, building the speed very slowly. Some did blow out but many didn't. The ones that did were just fished out and crushed.
