I am sure = that is difficult to me understand some technical words  that were used to = explain how to make the slot. I would like to know effectively how to make this = slot. I suppose that is something as to cut from one tip of the pin to the other = tip and with this cut, on that part cut,  the pin becomes half cylindrical = and half plane. There is no doubt that is good to cut 1/4 below the hole. There = is no doubt that is good to enlarge the hole but how to make the slot is a = problem. because some words like KERF or 'quick-slip' I can't understand. I = thanks to all.
