Shuffle board table, yes there are a few tricks involved. The problem is keeping it flat, or ever so slightly concave while the moisture levels in its enviorment change. The thicker you make it the less likely it is to cup. On better boards they actually put heavy gauge brackets on the bottom of the table near the edges and connect them together with all thread with two or three nuts on each end. That way the board can be bowed up in the middle by pulling the edges together and locking with the third nut, or bowed down in the middle by pushing the edge a part. These contraptions have a name but I can't remember it. I found that by the time I bought materials, milled them, build the rest of the table, that the customer could for the same price go out and buy a high quality board and I would never get called back for a warranty issue when he had a bad game.
I thought of building one for myself out of 12 foot long 1 1'4" MDF and doubling it up to 2 1/2 " and then laminating with wood grain Plam. Add three of those contraptions, and build a nice box to set it in with some fancy legs with adjustable feet and I would be ready to play! The only problem it would most likely sit next to the pinball machine, and foosball table that I never use(I do use the pool table on occasion, along with the kegerator). I am trying to get rid of the "junk" I have accumulated over the years not add to it. However I will keep the kegerator as long as my liver holds out.
