i am likely to try this for the first time this year. i would venture to say that by the time you get the frame in the extractor the wax will no longer be liquid, probably even if you drop it in right away.
+1Just about every subject pops up about every 4 months. Fortunately, most people here don't mind carrying on the conversation as if the question is new. If we did, there wouldn't be much discussion here.
I tried the heat gun method once a couple years back when I had only a few boxes to extract. It worked but I wasn't totally sold on the process then. I still have the heat gun (handy to have in the toolbox as Robbin said,) and might give it another shot when I extract next, now that you brought up the subject. Thanks for posting your question.
