I’ve come to your excellent forum after realizing I might be a little over my head with this project.
I’d like to build a dining room table to become a family heirloom (hopefully).
The plan is: 8’ long by 42” wide, 30” to the top surface, made of 2” or 2.5” or 3” black walnut. The support structure will be made of square steel tubing, two squares on each end, with an “X” of rectangular tubing across the top for support in the middle of the table.
The walnut top will be made of 5 boards (if we can find ones large enough), and edge jointed simply with glue.
The tabletop will then be placed on the steel frame with a layer of rubber on top of the steel, with bolts through the steel into threaded inserts in each plank. There will be at least two bolts through each plank at some point.
If any of this is unclear, I’ve attached a few pictures of my Sketchup model, but please feel free to ask for more.
The part I’m worried about is the wood top. I’m concerned with keeping the wood flat and true. The plan is to get partially milled boards, mill them slightly myself, then wait a few weeks to see if any movement ocurrs, then proceed. I am also planning on using slot-holes in the steel frame, to allow lateral shifting of the wood.
I would love any and all advice you can offer. I’ve never worked with such major, solid wood like this, and I want to make sure this goes as smoothly as possible.
