Possible router table tops & inserts
I have attached a couple of pictures and wondered if I could use these table tops as router table tops, especially the white table top? They look to be about 3/4" particle board with bracing. Also if I can use them should I somehow add additional bracing such as wood strips or angle iron? I have used a 1.5 HP router before in a table and intend to make or buy a table for a 3.25HP and 2.25HP router. If I do use these tops, as they are just lying around my shop, should I use the smaller router for the table as the 3/4" particle board may not have sufficient strength for a bigger beast? On another topic I have attached pictures of a set of three cutting boards that I picked up from BJ's for $15. They seem strong and would a piece make a good insert to mount to the router? Also as a final question as the bottom of the white table does not have laminate, to prevent possible moisture penetration what would you think of my spraying that insulating expanding foam on the surface. I know it is a wild and probably dumb idea, but it is just a thought as there are so many people here with good ideas.
