Well that's fine and I expect it work well, but I saw more than just the three tools you started the video with.

Forstner bit, brad point bit, I suppose a hacksaw to cut the allthread to length, socket and ratchet, dowel center, ... anyone count more than these?

I wonder how well the base holds up to loads that tend to push it out of square? There are no diagonals to resist these forces. I would be tempted to use a sheet of 1/8" ply (door skin is only $7 at Home Depot) on one of the long faces of the base to keep things square.

Now if only i had space to put such a bench...
