The only electric
chain saw in town was $300. I had to go back to work for 2 weeks, so on returning I got back to the problem. After a bit of cursing as to why the original builders would have done such a thing, I started my attack with a reciprocating saw, which cut ok but I could tell it was going to be a lengthy process. After cutting on each side, I noticed chunks of lead coming lose. After further inspection
with hamer, chisel & pry bar, I was delighted to find that the lead was poured in many small pours and not in one shot. Since I became owner of this vessel after salvaging it from 70' down, oily water
had penetrated every seam & void in this conglomerate of lead. The result is that a day of hammer, chisel, and prying has released me of this sinky, oily, lead. Reminded me of the many years ago when my cement truck ran out fuel
and I had to jack hammer 4m of cement out of the drum! The lead was much easier.
