Okay, I watched. They probably destroyed the chain on the chainsaw, made a lot of lead flakes (47 pounds!) and got the keel cut into two pieces. But why? I'm not being sarcastic, I cannot think of any reason to cut the keel up like that. Will the recycle center not accept as one big piece?
I have cut up a lead keel. It is soft stuff. Obviously a chain saw works. I discovered the importance of WD-40 and taking it slow when using a skill saw. It will heat up and melt, binding the blade if you are not careful. WD-40 and a carbide tipped skill saw blade go through it like butter. Handling lead is an unappreciated hazard. Lead dust, oxide, fumes etc. are potentially very harmful and long lived. The size of the chips produced using a chain saw might be safer than the smaller particles produced with a skill saw or even a hand saw. Preparing to catch everything is an important bit of preparation for the safety of those doing the work and any innocents who come across it later. Gloves and a respirator.

Most 24hr clinics do lead poison tests relatively cheap. If I were working with it, I'd get tested regularly.
I used to shoot revolvers with some folks on a frequent basis, a number of which would shoot lead. I did for a brief period (it's cheap), but stopped after I found out several of them had encountered health problems due to long term usage and handling of lead rounds. In a few cases, just a small bit of exposure was all that was necessary for lead poisoning to take effect.
I can see it now, keel sculptures made with chain saws. Instead of regattas we can have sculpture showings with everyone in scuba gear. Also a whole new sailing activity for the snow bound.
I don't see anything sick about using a chain saw. That is further supported by Downeast450's post as well as others. It's pretty difficult to get a full keel to fit into a bullet making melt pot.
