Time to start machining this puppy.

I had some imperfections in the bottom of the casting that I needed to weld up. I made a light cleanup pass to make sure I got everything filled.



Next is mapping out the combustion chambers to see exactly where they ended up. Castings shrink when they cool. Although there are formulas to use as guidelines it’s still a bit of a guessing game. All the core sand inside makes it especially hard.


So far so good!
