If it helps any. I have found a chainsaw cuts led like it was butter. Lead will bind the blade if you use a regular saw with little saw kerf. Save the metal shavings on a sheet of plywood
. There will be a lot of them.
It should be a mornings work to cut the keel
out of the boat and and buck it up into manageable blocks. Keep the blade clear of the attachment bolts embedded in the lead
Lead has a good value here. We melt our extra lead into 10# or 12# fishing
wieghts that can sell from $35 to $45 each retail.
The sawsall fitted with a long carbide blade will slice through a figreglass hull
quite easily. Have fun.
