Hello everyone, I don't usually post on forms and I'm using text-to-speech on my phone so be patient LOL! I'm a top bar beekeepier and have been keeping bees for about 6 years now and wanted to try my hand at langstroth hives, and wanting to go with eight frame foundationless deep equipment and was under the impression that all langstroth equipment was standardized but during my research have discovered that 8 frame equipment is not, I'm wanting to build most of my starting equipment for next year and one of the main reasons I'm even trying langstroth equipment is because I love the idea of being able to purchase equipment if needed from any supplier and it all working. Two books I have on building beekeeping equipment has conflicting measurements on the short side, one says 13 and 3/4 the other says 13 and 3/8 and the only three equipment dealers I can find that actually have measurements is Mann lake which says 14 in and the other two, i forget their name, say 13 and 3/4. Does anyone have any idea what the best measurement is to use or will I be in the same dilemma with 8 frame equipment as I am with top bar hives? Should I just go with 10 frame equipment for standardization?
