Hey everyone, I'm in the process of building the engine for my cobra and I was looking in to studding the crankshaft. I believe its something I can myself in my shop but i wanted to find out mainly how deep to drill the hole and how deep do u relief the hole for the threads or do u thread it the entire distance. has anyone else done this there self and if so how did u do it, lathe, mill, hand drill. I'm also going to cut it for 3/16 square key do I need to do one 180 deg from the original. with all that done do u do away with the press fit on the balancer and make it a slip fit. I was going to modify my lower pully support until i read that snots break from a torsional event and the pully support doesn't prevent that, and with the stud u really don't have a support. I called a couple of local automotive machine shops and they said the could doubled key the crank but they have never studded a snot before. So any help I can get from u guys will be much appreciated.
