Tim, forget the bandsaw - welcome to the world of FORGING!!
Got a big hammer?
If you want some practice and want to really find out what it's like to move steel around, get that bar up to forging heat and beat it down to the size you want!
Lay it over on its edge, beat it down narrower, then over to the anvil horn and lay flat and draw it out lengthwise to its original thickness.
You can do it.
Piece of cake.
