Ron, Answer to Question 1. Steam may work as well but I prefer the vinegar as it really softens and loosens the joint which makes the answer for question 2 much less of a risk. I found that a firm grip on the hammer prevented much of a strain on the flange. The knuckles lifted out with relative ease. However, your point is well taken. I guess applying the vinegar to the knuckles while on the stack and then removing the hammers to remove the knuckle may be a safer way to go.
