I need to put a blind slot into a hole, about 8" deep. See photos for the general idea. Would start with the block (aluminum) that already has a hole, and my thought was to make a sort of drill bushing out of steel, make the slot in the steel bushing via ball endmill, start the slot in the aluminum with an endmill to at least get 2-3x "diameter" slot depth, then proceed with drilling the rest of the way down using the bushing/guide to prevent the drill from walking "away" into the thru-hole. Obviously the guide/bushing would be held in place via some method. My intial thought was sinker EDM, but I don't have one, and even if I did it's time consuming. My 2nd thought was shaper, but there's no provision for a relief of any kind at the bottom nor a way to access it. (block part has been hugely simplified to just show the idea of the guide/bushing).
Do you think this will work?
