So.. I made a table

Materials

I purchased around $60-70 worth of lumber from 84 lumber and Lowe's. 2x4, 2x6, 4x4, and 2x2.

Notched the 4x4 lumber to accept a 2x4

Here's the bottom of the table all assembled

Test fitting the top of the table made out of 2x6 lumber

Top of the table assembled and test fitting the 2x6 breadboard ends

Moved project outside to be sanded

Test fitting table extensions. They will basically support an additional 3 - 2x6 boards on both ends. Adds roughly 16.5" additional table stop length to each side.

Stained and waxed the frame of the table

I experimented with making my own wood filler... it didn't accept stain.

Stained and waxed the top of the table

Assembled and in my dining room without extensions. Still need to find some chairs...

Roughly followed these plans with my own modifications. My table will accept 6-8 people without extensions and up to 12 people with the extensions. This is the first table I've built.
