Hello, first post to this forum. My wife bought about 300 frames from a retired commecial beekeep for langstroth hive bodies which are 7 1/4" long (that was super cheap $25 with other stuffs including queen rearing stuff wax foundations etc.). With this came 2 super hive bodies which are 7 5/8" deep and hold 10 frames. From my understanding, 3/4 supers with these dimensions were popular in the past when 1 by 8 boards were actually .75" thick and 7 5/8" wide. However, I cannot find them anymore as they are now 7 1/4" wide (we are getting ripped off). I have tried to find inexpensive solutions (I do have a wood shop) and the cheapest and most practical seems to get 8' by 4' marine plywood at the local Lowes which retails for about $75. I can then cut 7 hive bodies out of that (actually 7.5 hive bodies) for about $10 a hive body which should last a very long time since it is marine 3/4" thick plywood. The other option would be to splice three piece of 1 by 3 furring strip boards (which are often a challenge to get straight) for a final cost of about 4-5 dollars a hive body. What do you guys think? and do you know of a supplier who carries 7 5/8" hive bodies (I checked Mann Lake but they no longer carry them). Cheers to all. News: I just called MannLake Ltd and I found out that they do have 7 5/8 hive bodies (in all three grades they carry). Cost is however $13.95 a hive body. gandmhoney also carry some for about the same price. I guess, I will just build mine out of marine plywood then. Hope this info can be useful for some.
