Oops on crank case

[Zetomagneto]

Been there.
I found, after I had built my engine, that I had crack by the starter motor stud.
I took the engine out and my friend Nick, a man with TIG skills, welded it back up on the bench. I then redrilled and tapped the starter stud hole by mounting a wooden board across the gearbox top face and used a power drill in a vertical stand, ensuring a new, square hole.

Not a disaster and very fixable. Just find a good TIG welder.

With you there Charles, Tig welders (good ones) are our friends
