I'll write up more tomorrow after leaving the house at 5am and getting home a quarter after nine PM and ~370 miles on the road I'm tired.

I have not done anymore porting but will be doing more work now to balance the chamber sizes, take the largest one and match the other's too it.

I'll leave this picture here though.
