re: I'm going to be building a farmhouse table soon. Any tips?

When I did mine I used pocket holes, glue, and pipe clamps to join the top boards together. It was relatively straightforward and I'd recommend it, but I didn't do breadboard ends.

Like you I stressed most about how to attach the top to the base. I went with these:


You set your table saw fence at the width of the offset of fasteners, and cut a kerf into the inside of the aprons. Then screw the fasteners with enough play to allow for expansion. This was the best solution I found and going on two years with mine with no cracks. They can also be swiveled to remove the top.
