I'm putting all these news frames together, and putting foundation and support pins in them. One manufacturer has the holes in the side bars really clean, and the pins slid right in with thumb pressure only. The other manufacturer, the holes are very rough, and you literally have to drive the support pins in with a hammer. The pins are almost $50 a pound. Actually, there is suppose to be 1000 pins, in a little bag, for this much, and it can't be more than a pound and a half. The question occurs to me, "Why not just use nails in these holes? Once the comb is built around them, they will be secure, and they will extend a whole lot further into the foundation, than the little pins." Honey has little water in it, so there should not be much rust, and I did not really want to use galvanized. Have any of you tried this? I sure don't want to take all the time necessary to stretch wire across these things. I have never experienced blow outs in the extractor, but I have never used a radial, which I am now considering. I can see how the comb might blow out of frame, when spun on a radial.
