Topping the polished pistons

If you've seen the first Moana.....the 🦀

Now please read this before you cruise through the pics. I made the mistake of sharing some numbers(fudged numbers) for that I'm sorry. The client didn't give me permission to post anything even if they were lower than recorded. 🤫(he races after class)

But 340ish/270ish @ .700 he said "ish" numbers are ok.

The chamber finish is purely cosmetic, but the shape is functional. I hope the pics upload nicely.

The finished pics are in another post.
