Just cut a bunch of cast protuberances off an old printing press frame..
Was afraid to use a torch and a piece of sacrifice steel to keep the cut 
going  ( exothermic) because of expansion cracking.
Used slitting disks on the 4" grinder  ( fussy) followed by the sawzall for 
the core.
Had there been more room, would have used a trashy worm-drive skillsaw and 
a cut off wheel.
There are also arc cutting rods ( discover the duty cycle on your welder).
The casting on the Common Sense hammer I had to cut to repair was much too 
hard for a sawzall blade ( save the carbide grit kind).
