I'm about to attempt to make a heavy cutting block that will be 20"x20"x 16" thick. I've made a few end grain boards already. Is there anything different that has to be done with a block this size. I see on some there seems to be a few plugs in the sides that I surmise is for threaded rods for extra precaution to hold them together. I will be using rock maple & some other wood intermixed. Can I sill use tight bond 3 or is some other glue more suitable. I thought of epoxy but thats not good for chopping food on....Any ideas would be appreciated
