weldin of a crank

i do thinking sometime......... more torque... i think i will try one crank...i do weldin every day.....

[Mark Halligan]

It is done to repair journals or change stroke, but takes skill to weld and machine (pic of welded journal before machining below).

You probably wont find anyone here who has done it

Try searching or asking on some of the engine building forums like Speed talk

I have heard of this too. Use a stick welder. Not sure which rod to use. The journal should be hardened after.
