mills boiler

You can do either method, but I prefer the cutting method. I feel more in control that way.
The replacement nipples are readily available. If you are doing ALL nipples and dropping the drum, the standard nipples will work. If you aren't, there are weldable 2 piece nipples available. Keep in mind, if 1 or 2 nipples are rotted, the rest are probably getting there.

Another job that brings back painful, dirty memories. And not dirty in the good way, either.

Those drums are heavy.
