Breaking up metals.

(1/3) > >>

NeoTech:
So im in need of breaking up a about 1500kg of cast iron in the form of engine blocks and crankshafts. So of couse i can saw them up .. But it would be more interesting to make something like a rock crusher, a hammar mill, shredder or something similar... Would it be possible to make for metals?

awemawson:
Things like engine blocks have significant mass which makes melting difficult on a small scale and will resist many ways of physically breaking them.

I reckon for that volume you need to make yourself a thermal lance. At it's simplest it's just a steel tube packed with thin steel rods, with oxygen being blown though it:

JHovel:
I doubt that a thermal lance is practical. However, I suspect a decent size plasma cutter would work well. Something that will do 2" or 3" severance cuts.

Jonny:
How about cleaning up the engine blocks and making tables out of them.
Just the job for man caves.

Why the need to break up.
Take in whole to scrap metals and get some money out of it.

JHovel:
Hey, this is a 'mad modder' forum. Taking scrap to the scappy is not allowed here.  :mmr:
He clearly wants to recycle the cast iron and melt it down to cast new parts - and engine blocks just don't fit into his crucibles....
