I was given a big ole maple butcher-block. I don't know what it weighs but I'm guessing well over 400 pounds. Lives where risked getting on the first leg of it journey to my shop. I'm thinking that it would make a good joinery bench, but I feel like it will be hard to keep it from being top heavy and hazardous. The original legs are tenoned into the bottom and wobbly. The kind person who was trying to help me move it jumped in and almost got a foot crushed when it went over. I didn't measure it but I'll guess its a 32x32x20" block. So its not getting a face vise. Any suggestions?
