Why isn the Drawhive in solid wood?
It would be lighter in weight, but there are two reasons for using plywood. Firstly, shrinkage with changes in moisture content could upset the bee-space and cause distortion of the parts, in solid wood. Plywood is much more stable. Secondly, as there are different thicknesses of material in a Drawhive, it would require a lot of machining to produce in solid wood. Plywood is easily available in wide panels of the required thickness, so the cost is lower than it would be in solid timber.
