Slab table design and considerations
I'm about to pull the trigger on some walnut slabs and wanted to get some advice from you all. I have build tables in the past but never a slab table. I am looking at two slabs and the table will be about 8 ft long. I have seen slab tables like this that leave about a quarter inch gap between the two pieces down the table top. Is this done to allow for movement? I have also seen dominos or floating tenons used between the pieces. I'm guessing this is to keep the table flat. I'm going to be constructing a steel base with square tubbing and probably a steel runner down the length of the table to stop the table from racking. I was planning on using lag bolts and elongated holes to attach the top to the base. Please leave any advice that might help me on this new adventure! Thanks!
