Re: Any Diy alternatives to making a bottom boards and tops for bee hives
If you are referring to the bottom board illustrated as part of this Beesource plan:
the most difficult part (without a router or table saw) is cutting dados in the side pieces to enclose the edges of the plywood. You really don't have to make dados. You can just cut the very bottom part of the sidewall separately, and make the plywood extend the full 16 1/4" width. Glue the bottom part of the sidewall to the plywood, and then similarly do the top part of the sidewall. Effectively you are just sandwiching the plywood with the sidewall pieces. Repeat for the other sides.
Keep in mind that the formerly protected plywood edge is now exposed to the elements, so be sure to seal it. Painting glue on the edge is one approach.
I would also encourage you to troll your local Craigslist for an affordable table saw.
