I have never done the cutting of an input shaft, but i would probably go
dremel myself. I would however recommend strongly against removing the input
shaft, heating it to cherry in a forge, placing it on an anvil, and cutting
it with a cold chisel. I really just cant see that method working out
well....the end might be slightly distorted (but a good blacksmith with a
skilled hammer should be able to take care of that).
List that one under "ways NOT to cut input shaft".
Hey, its friday.
