I'm making a dining room table and the top is solid wood. I plan on attaching it to the aprons with shop-made buttons to allow for wood movement.
If the buttons are 3/4" thick, should I use 1" or 1 1/4" screws? My top is walnut and is 1" thick. From what I've seen, most are screwed directly to the table bottom without a hole being pre-drilled and I want sufficient grab without risking splitting up the wood.
