I came into some great #2 and better 1x8 that I want to make into 6 5/8th honey supers. I want to do this on shares with a beekeeper that does woodworking but do not know what the split should be. If I provide the wood, screws and glue what is a fair trade for labor of cutting and assembly if they are lap joints. I thought 60-40 would be generuous. Any thoughts out there?
