It doesn't matter whether it's ply or cedar or pine or 18mm or 22mm.Just a note on the ply. It looks like 18mm can you mix it with the 22mm bought cedar stuff or do you have to use all the same. Im thinking you will get steps in the varying widths, is this a problem?
I have cedar stuff and it would be good news if i could mix it up and make my own.
Just a bit more hijacking of this thread sorry.Onge I've given dimensions for B.S. Modified National, whereas I've just noticed you have Mod Dadant hives. The principles are the same but the dimensions are different, particularly the lug rebate. There is a sticky giving Dadant dimensions elsewhere on this forum.
I did make some Smith boxes from 18mm ply with good success and Dadants are very similar but bigger.
