Hi All,

3 questions about building the 4' x 8' deck for my ShopBot.

1) The assembly manual suggests first layer should be "3/4 inch shop grade or cabinet grade plywood or better (birch, maple, poplar.... hardwoods)" attached by carriage bolts to the frame. Is this plywood something I can buy from Home Depot or Lowes? I remember seeing expensive plywood that was really smooth on both sides.

2) For the next layer it suggests gluing 1/2" or 3/4" MDF and then leveling using the TableTop Surfacer Virtual Tool. Would anyone recommend screwing down this layer with counter sunk screws instead? This would allow me to remove the MDF or carriage bolts if ever required in the future. Example: maybe I want to add mods later for a vaccuum table.

3) How do you'll attach the final spoiler board to the bed? Seems like using screws from the top down would eventually wear out the middle layer MDF. Wonder if long screws from the bottom up would be a crazy idea.

Thx
