Even though this is slightly OT for this ng, the helpful advice on this ng is admired and valued. I have removed the rotted wood top and sewing machine from an old Singer treadle sewing machine and am going to replace the wood top with a piece of one inch thick cultured marble and use it as a table. There are four screw holes (one at each corner) in the cast iron chassis. Any suggestions as to how I can securely fasten the cultured marble top to the four cast iron posts? I know I can drill the cultured marble using masonry bits, but doubt will the resulting holes will take threads from metal screws. Suggestions appreciated.
