G’day Will I used to teach DT here in UK if I can help I will.
Where do you live, perhaps we can get you to meet up with local beeks from here or a BBKA where we can get you some hands on help.
Here is a bee Source pdf of the dimensions http://www.beesource.com/files/10frlang.pdf
The better boxes are made of cedar, I assume your school has various jigs and lathes to cut the dove tails?
This box does not show the nice handle grips it is more like a National hive.
The Flow Super’s are the same size as the brood box, so basically you will need 2 brood boxes and an extra super if you so choose.
This one looks Better. It also show the Frames - I can send you an unassembled Frame if you want to cut your own?
This one is a nice image of how it fits together
This one is a good site as well
