Had enough time tonight to mount the proposed cabin table support. Ran a couple of small pieces fore and aft between two of the cabin wall supports. Then cut the shelf support strip in two (4′ length was all that was available) and mounted each strip vertically on the two horizontal boards.

Then you can put the shelf brackets at the height you want the table. I’ll get a table top cut and fastened to the shelf brackets so its one unit and I think it will be good to go.

Time = 30 minutes
