whose ductile seats
I've had to replace too many "chrome moly" cheap seets
I call them "muffler tubing"
I got the DI seats from Kibblewhite, CV Products and one other place I can’t think of.
Then one day the dim bulb in my brain went on and I realized...”you’re a machinist...why are you BUYING sized seats that may be bigger than you want, or the wrong thickness, or the ID is not what you want...why not buy a stick or two of ductile iron stock and make my own”?
So I started making my own seats. I charged extra but it was worth it. I could make them any thickness I wanted, any OD or ID...whatever I wanted.
I also had adjustable cutters so I didn’t need a nominal OD.
