Sanels in either Manchester or Concord will do it.I forget which one it is,but a friend just had his done.They said the equipment had not been used for 30 years or more,but the guy in the shop thought he could remember how and he did a great job.Now,the next question is,did you just cut away the rolled over part of the stud? Did you leave the tapered part of the hole in the drum?An unmodified hole saw will just cut straight down,all the way to the hub surface,taking out the important chamfer in the hole.That is unimportant to most,as the drums are usually being removed to make way for new cast ones.My friend started out the same way as you,he had bad studs with good drums.He cut out the studs using a hole saw,not realizing he had to cut a tapered hole without touching the drums.He took them to the shop where they told him he had ruined the drums.I aimed him at Mel Gross,and he bought a set of new cast drums.I have his old(ruined)drums,trying to dream up something to do with them.They all measure .130 so they are pretty nice.He actually ruined the studs from some advice he got here on the Fordbarn a couple of years ago.He torqued them to 100 foot pounds,and the studs mae wested.The threads were OK in the lugs,but where they passed through the wheel holes they got skinny,or hourglass shaped.The wheels started to chuck,ruining one and shearing off a few studs all around.
