Tongue and Groove for TableTop?
I'm new to woodworking apart from a few woodshop classes 20 years ago, but I'd like to try my hand at making some simple furniture starting with a small console table.
I'm planning on making the top of my console table out 3 planks of 1x6 pine, with two more 1x6 pieces running in the opposite directions to make up the ends. I understand that it's pretty common to simply glue and clamp the planks together, however I'd like to ensure that the top remains flat without cupping and eliminate as much of the sanding phase as possible. Would it be of any benefit to use a tongue and groove router bit set to create a tongue and groove assembly for my table top boards?
If this turns out well enough, I'd like to expand into a larger kitchen table using 2x8 boards... in a project that size the glue up phase is even more difficult. I don't think a router bit set will cut wood that thick. How would I create tongue and groove in wood of that thickness?
Or am I simply looking at this all wrong. Any advice is appreciated!!!
