It would be nice to know approximately the friction budget of our launch engines. Given the wear and breakage issues of many such val...

Sorry. I missed that this wasn't an active construction project.

That said, using anything but cast iron in this application is just asking for trouble. In my humble opinion (snorting in the background from my wife).
