In retrospect, I wish I had videod this effort. I was given 6 stainless steel cylinders that actually work in my pietta Buffalo, but the problem was, as you all know, there is always one... in this case 4 nipples that were frozen in so tight that I broke two nipple wrenches even though they were soaking in a penetrant.
What I finally wound up doing was taking a drill bit slightly larger than the nipple flash hole and drilled all the way through. I then took a slightly larger bit and followed it through the nipple just taking care to be mindful of orientation. Once the second drill bit went through I then tapped in a craftsman extractor and it came out almost too easily.
This was followed by the other three just as easily. True, it took 24 hours of soaking for the first 32 and two broken wrenches and an additional 24 hours for the last 4 stainless nipples to be extracted, but I'm posting this because I'd been told that this was an almost impossible task. It is not. I think the drilling of the nipple weakens the walls of the nipple and the extractor is able to easily overcome what little corrosion remains.
If this is old hat to everyone, I apologize, but I kept hearing horror stories about trying to free stuck nipples and all kinds of remedies... heating, using sockets and all sorts of bad outcomes. This if you take care in your alignment of the nipple as you drill, is like peanut butter spread... I'm not sure why drilling isn't the first remedy considered.
Aloha...
