Jerry,I think that I am going to tackle them with a Dremel. That does seem like a very good alternative. I feel pretty comfortable using one. Will be sure not to take off any more material than necessary. Dave, my valves were so far out of adjustment and noisy. I am sure that they will be quieter than they were when we started. Even if the adjustments may not be as accurate as the could be, with all new pieces. As always, I really appreciate your advice and guidance.
