Cleaning block, testing laser

[3W Hank]

Yes you are correct.
I will do mainly engine parts as ex blocks so I will not stop use caustic sodium and citrus accid.
Ex right now I has 2 of 392 heads in accid and they been in hot tank twice before the accid but to get the total cast iron look ( then the laser comes in )
-Will anyone pay me, no way, the average guy say he use diesel and screwdrivers for fee, but I talking here on a ’total’ clean block, I do this as I love USA cast iron.
It’s a passion.
I know I’m probly mental lost but I’m aware of it it and no one get on trouble…
