Then final sanded the top flat and finished the table a day later. Two weeks after finishing the table I could see biscuit shaped dents in the smooth finished top where the glue on the biscuits had thoroughly dried and shrunk, pulling the dents in the top. I had to make a whole new top for that table and have avoided gluing biscuits in flat panel assemblies ever since. I glue the board edges, but avoid gluing the biscuits.
When strength is needed, I use the FMT for the mortises and matching tenons, or for just the mortises and then use floating tenons. It depends on the application which way I go. Set up of the FMT likely takes longer than the Domino, but it's just as fast when using it.
