I have purchased my lumber and materials but here's my problem.
1) The Langstroth plans I have from beesource show an external dimension of 19 7/8"L X 6 5/8"H. The internal dimension is 18 3/8"L a difference of 1 1/2". In the deatail they are shoing an additional 3/4" board on the inside which should create the frame rest, but the problem is they show a 3/8" deep frame rest, 5/8" to the top of the box, and 3/8" thickness, the numbers don't add up.
2) Also, I'm building all mediums which should have an overall height of 6 5/8", less the 5/8" for the frame rest, leaving 6". The frames are 6 1/4" which would leave them sticking out the bottom of the box.
3)If the Langstroth measurements I have are correct do all the boxes rest on only 3/8". Seems like this might be a little tricky to line up?
4) Using all mediums/10 frames, what would be the best frame/foundation to use. I want to use a 4.9mm small cell foundation because I like the info from MB, Brian, and others regarding mites, diseases, etc...
Thanks for allyour help!
