Anchor depth

They should be large enough so that the nearest an anchor bolt will be to a new edge is at least 4 inches. So you can make it 8 inches wider and longer than the baseplate. I myself like to oversize things, so 4 inches to edge is a minimum. 6 inches would be better. If you go that route, make it 12 inches wider and longer than the baseplate.

let me see if I’m understanding this correctly. I’ve attached some pictures of what I believe would be correct in the way I’m to go about this. How close should these new cuts be to the control joint? Since my lift will have to be placed exactly 6inches from the control joint and I need to have at least a few inches from the edge of the new hole. Wouldn’t I have to cut the squares relatively close to the control joint? Like maybe 2 inches? First pic: top view, second pic: side view, third pic: overall top view layout
