Broken crankshaft

[ws23rt]

I bought this crank years ago and the engine builder I use found a crack in the radius of the first throw.
My question is can these sometimes be repaired? Or do I have a fine piece of scrap metal.
I know that journals can be welded up and turned back to size.
It is an 8bolt Velasco crank.
The crack shows in the second pic.

junk , boat anchor, , good after market cranks cheaper , what if the guy who welds it up doesn't do the job properly, think of everything else that get destroyed when that lets go

Wow it never crossed my mind that it might be a reverse turn crank. Gees LH may mean something important.
Thanks for that thought. So all it needs is a hook to be a real boat anchor.
A reverse turn boat anchor for those that throw it off the left side?
OOps sorry port side.

looking at the oil hole chamfer  ,it is going the wrong direction for an automotive crank

Thanks I would have never thought of that. But now I will never forget it

Yep, used speed parts can be a gamble at best. To be hurt that bad, that crank has seen some insane power levels. I wouldn't trust it.

Yep, that there is a used up Blown Nitro Crank.
IMO,
That particular one looks to be cracked pretty bad and best junked, especially since nowadays a Chinese 4340 can be had very cheaply.
