I need to put the big hole in the little cover. I'm going to try to do this myself. This will be my first attempt to make something important with my mill. I bought the big block cover from Summit for $52. My plan is to cut the big block seal holder out of the cover with my rotary vice and bore a hole to fit in my 292 cover and mind meld them together. It looks like it will just fit. I ordered this boring head.
