Just started cutting today as my drill press is to small to reach the center, I can only drill 4" in So I could gain a bit by cutting up to the border off but I'm a bit hesitant as to it may weaken the whole thing and I still won't be able to reach the center, So tomorrow I may go to town to see about buying a dremmel and dremmel drill press I just don't see how else I'm going to do it.
Anyone have any advise?
