Thanks guys! Wow, I'm seeing some radical work there. Not quite the extent I'll be going to... Awesome!!
I found a 4-1/2" grinder wheel does most of the work, some places can't be reached so a carbide bit takes over. Then I ran a hand file over all the surfaces to smooth out the marks, then some 80 grit cloth. I didn't like those notches carved out of four of the arms, I smoothed out these areas and rounded out all sharp edges
Tip: tape up all the journals real good before you start any grinding, you don't want to nick it.
I have ten hours work into my crank so far, will do a bit of counterweight leading/trailing edge work and call it good.
Should a crank be shot-peened next?
Smokey says cranks must have the journals re-hard surfaced, a job overlooked by most. He says to even lightly polish the journal afterwards is a no no. Anyone ever heard of that?
I've done all this work to a crank with a hideous #1 rod journal. Hope it will grind out, otherwise this crank goes to Crankshaft Craftsmen for some welding and stretching. I hear a 2.2 stroke works pretty good these days...
