I started on the base/bottom of the table yesterday.
I took the whole top section and set it aside.
I removed the sides and legs and sized up the parts left over.
I removed the extension piece I had added on the last upgrade, as it was a piece of 1/2″ OSB mating up to 3/4″ for the main table. I had purchase a piece of 3/4″ a couple weeks ago and it was time to put it to use.
I used a couple of 4 foot 2×4’s underneath the main table and screwed the new section on.
I pieced together some of the legs and 2×4 lumber into a basic frame. I decided to re-use the blue board that I had as a shelf under the table, between the back legs. This shelf gives you somewhere to store extra chips and trays and all the stuff you need. It also added some support to the free standing legs. It also gave me a pre-set dimension for length to start with.
Here is the free standing structure for the base. Notice the top behind it with the 2×4’s and extension piece.
