Have to ask after reading some of the replies, does anyone use glue on frames and NO NAILS?
I think this is an important question. Is the pole asking if glue is stronger than the a proper stapled joint applied in the correct way? If you are going to use both then the poll is a dumb question.
I suggest that this can only be answered by qualified testing. In one case you glue the joint with no other mechanical fasteners. The other cases you staple the joint with a number of staplers of different lengths and sizes. In all cases there must be a cross staple in the top bar. There must be a minimum of 100 frames tested in each category so you get a good standard deviation. The frames should be put in strong hives for one season and have the bees propolize the heck out of them (like they do in my hives). At the end of the season a standard pull test machine should be used to pull the frames apart recording the maximum pull force. Many engineering labs in schools across the country can do this for free.
Now the only thing to ask is what is necessary and what is overkill. If the comb would be thrown from a frame in an extraction process before the frame parts come apart then there is no sense in having the frame joints stronger. Unless, unless, the failure of the frame occurs at the time of removal from the box and not from the extraction process itself.
When I helped Mark B. extract honey in NewHartford we flipped the boxes over and dumped them on to a flat surface and if the frames didn't fall out you could just push on the bottom bars and remove the box and all the frames would just fall to one side. There were a few where the frames just collapsed under their own weight and I would hear Mark mumbling to himself about buying someone else's equipment and then he would start throwing frame parts in the corner of the room. I guess it was a burn pile.
Taking a pole of what beekeepers think is not very scientific ... just saying. In another topic the forum was ridiculing STEM as it has no usefulness in beekeeping. Really?
