Cutting a block of lead.

Apologies if this isn't the right forum. I have a block of lead that was poured into a coffee can long ago. Managed to cut the tin off but now to get small enough hunks of it to fit in my melting pot. Tried cutting it with various saws and blades, not much luck. Only have a propane camp stove for outside and I doubt there's enough BTU for that to work, or is there? Guess I'd need a cast iron pan to try that. Any suggestions out there? Thanks.
 
Can't help you directly, but if you apply direct torch heat, like with a propane torch, tiger torch, oxy acetylene, it will melt, but you will overheat the lead and get ingots with blue and gold colours. You can probably guess how I discovered that! If I were in your shoes, I would probably try cutting it up with my big chisels, or an axe - use the shearing / cutting action - the lead should yield. I tried many saw types, including skil saw, hand saw, hack saw, jig saw, reciprocating saw and none got more than an inch or two before seizing in place. If you can get a $2 cast fry pan, might try tiger torch underneath - would melt before tempering the lead?? If you build wind/heat shield around pot and stove, I have melted 10 lbs or more at a time on a two burner Coleman propane camp stove - in a flat bottom cast iron bucket - took 1/2 hour before it was melted.
 
If cutting with a bandsaw or recip, use oil for cutting. It keeps the temp down and reduces binding. Lead isn't as easy as you'd think to cut. The oil burns off in the pot.
 
Should have melted it in the tin coffee can. Then poured/scooped it into a liquid graphite coated muffin tin. Buy a plumbers propane torch and melt it into a graphite coated muffin tray. Cutting it is a lot of work. Ask the guys who cut a sailboat keel in pieces. Chainsaws with extra oil poured on.
 
Borrow a buddy's dutch oven?

Just kidding! Maybe a steel pail 16lt -20lt on tope of a propane burner like the ones used to deep fry a turkey might work.

I have cut much smaller sizes with a power saw, it took two of us a long time, not fun at all.

You could try a place that recycles metals,they have big press cutters, maybe for a small fee they would chop it for ya, it might be worth it.
 
Short of melting it down and pouring it into smaller sizes, a machete and a heavy hammer and cleave off chunks at a time. Trying to use a saw will just foul the teeth with lead in a hurry.
 
Put a piece of steel mesh/ expanded metal (mine has 3/4" holes) over a steel pail half full of water heat the block with a tiger torch the lead melts through the mesh like rain drops and cools in the water making a bunch of pellets that will fit easily into your furnace. I salvaged a lot of lead that way.

I should mention to do this outside with a respirator
 
Head to the second hand store.
Find a 2$ pot that will hold the chunk of lead.
Fire up the camp stove and have at it.
Ladle the lead to smaller ingots. I use muffin tins. You can pick up one at the second hand store.
Use the pot later to smelt wheel weights.
That's what I did.

THIS has GOT to be one of the best threads I've read in a while.
This is like figuring out a math riddle, but for re loaders.
Lots of ideas to get this task accomplished!
 
The coarser the teeth, and the greater the "set" of the teeth, the easier it is to saw lead.
Be sure to keep and melt down the lead "sawdust" lol. Dave.
 
drill a hole in it. About 1/4 diameter, 3/4'' deep
fill hole with tightroup
light a wooden match
place the part of the match that's not burning on the powder
run like hell

need to seal it up, all that will do is make a nice fireball.
