I know this is probably a known trick to experienced beeks. I have hundreds of frames put together that I need to get foundation in. Ben watching videos on wiring frames and was dreading it. Been using those little split pins and they are expensive. Sold some equipment to a beekeeper today and we were talking bees in the driveway. We were discussing frames and I asked him if he used wire, or those expensive little split pins you insert in the sides. He said neither. He uses those metal hair pins that women use on rollers. They are cheap a Walmart and work great. I was able to put 3 deeps together in no time tonight. 90 pins for 1.94. That just made my day. Hopefully I have added some value to the forum tonight.
