Hi, I was just wondering if it was was possible to build a hive using just a router. If so, what kind of router/size of bit would be necessary. I was thinking of building with box joints.
If you have an 8' or 10' or 12' piece of lumber, it is challenging to cut it to length with a router, but it can be done. So as Michael said, you will want to have some kind of saw on hand, even if it is a hand saw.
The rest can be done with only a router if that is the only power tool you own. The box joints (or rabbets if you prefer) for the corners of the boxes, the rabbets for the frame rests and even a nice "routed out" handle for the sides of the boxes can all be done with a router. Go with a bit sized for the box joints you want to make. You can use the same bit to do the rabbets by setting a fence the proper distance on a router table.
I do not recommend using the router to pound in the nails however!
