I built two benches so far. One for the house and one in the cabin. The house one was from dimensional labor and it is great. The cabin one was from recycled pallets and it came out awesome too with room for miter saw in the middle. I will be upgrading the top of this bench shortly because rifht now it is made of 1 inch ply wood. I'll post pictures later.
I recommend preparing your bench with bench dogs. Square and round
