I’m looking into putting my experience as a CAD draftsman and also my experience from a previous job as a CNC router programmer/machinist into practise by making some supers to house my new flow frames. I’m trying to save a few bob whilst giving me something to do. I’m looking at getting a 2400x1200 sheet of 19mm marine grade plywood and machining as many supers as I can out of .
I can design the box in 3D software used in the cabinetmaking industry and simply send this through to the flat bed CNC for machining. It will include all the cut outs for observation windows, tool insertions etc etc just like the boxes flow sells. The only thing I will do different is that instead of doing the fingers joints I am planning to do a tongue and groove joints combined with screw and glue.
My questions are-
- Can anyone comment on the success of plywood used for hive boxes? I am planning to paint the outsides of the plywood with some exterior paint.
- I am getting some contradicting dimensions for what size to make these 8 frame boxes from. The flow team in their details for modifying langstroths says the internal measurement are 310mm x 465mm x 245mm high. Am I good to proceed with these internal measurements or does someone have something to add or correct here.
- What are the correct rebate dimensions on the box ends that the frames sit on. Is the depth to this rebate working to maintain a certain size gap from the top of the box to the top of the frame?
Any help much appreciated
