grill table

Building an outdoor grilling table for my new 26.5 out of local sawmill lumber. What diameter would you cut the hole? I am not planning to use screws or brackets at this point to seat the grill into the wooden table. I've seen others just drop it into place and say it does not burn the wood...

I was recently VERY impressed by photos of a kettle grill table designed and built by BBQ Brother "BigBlock": So much so that I decided to try to replicate the table for myself. Here's how it turned out: Have used it a few times and LOVE it. Thanks, BigBlock!
