Gluing wood to cement
I have a round, 20 pound, 24 inch, cement table top inlaid with small tile pieces. I ordered a base on which to mount it. Where the base supports the top are three holes to use as anchor points. I plan to use a smaller piece of round wood, glued to the bottom of the cement top, as the "in between" part. I will insert bolts through the wood to fasten to the base prior to gluing the wood.
My question: What is the best way to glue the wood to the underside of the table top?
