found the 19/32 freeze plug today but where does one find the 10" drill bit? is drilling this out something a guy can do at home in his garage? if i want can i just go with the freeze plug trick? not real comfortable drilling on a angle. just picture the drill bit biteing hard and snaping off and me haveing a big problem i do not need! some what of a novice. only have enough money to build this motor one time thanks in advance brent
