the turbine roter is 15 in cut out with a water jet cutter it made all the cuts and holes in 1 operation. sure saved me a lot of work . on the rim is 1/2 strap that i made in a circle about 3/16ths to small. then heated it up and hammered it on like a ringgear on a fly wheel when cooled it shrinks and becomes a press fit. i put a few spot welds to make sure.havent figgured out yet how to install more than one photo at a time still working on that.
