What type of saw is used to cut the dove tale in a super or deep hive, would a scroll saw work?
To get good alignment of dovetails or square cuts, it is best to use a special jig. These are usually designed to be used with a router. Check in the router section of your favorite toy(tool)catalog
cutting box joints..
To cut box joints you can use a table saw with a dado blade and a jig. Either make a jig or buy one. Any store that sells power tools should have one. To make dovetails you will need a router and dovetail jig or you could hand cut them. We had a gentleman from our wood workers guild show us how he hand cuts dovetails. Nice finish work but not for the novice.
Beehives normally use box joints. To use a scroll saw would be very time consuming since each one would have to be cut individually.
Cutting a dovetail would be more practical, since you could determine more easily how many you would use.
A simple way would be to cut the tails, then use the tails to mark the pins with a scribe.
Here is the best jig I have found for cutting box joints on a table saw:
