Cutting a round metal object

[master53yoda]

Don't cut the ends off. Freeze the can and its contents.Now it will be rigid when you cut it.
Now hacksaw it in half (maybe a reciprocating saw would be good at this time. Or even a Dremel tool.

After it thaws an emptied, you can use a can opener to remove the top and bottom from the half cans.

I'm not sure if I'm tongue in cheek or not?

Excellent idea!!!!! you might just take the can after taking the food out and fill it with water and freeze then cut, that way you get to use the food to.

You're using lead-free solder, right?

Nope, and my dentist still uses mercury in the amalgam.
