Looks like the needle valve in the picture Don, but it's .140" square where the needle valve is .172" and about twice as long.
Well I wouldn't say I fluent in computer, but I actually had to start using them when we got our first Sheffield CMM's in down at work. Our first computer was a HP 8088 about the size of a suit case, and I'd tot it home at night so I could learn DOS and HP Basic to make the darn thing run. They have sure come along way since then. About the only contact I have with programing now a days is to run one. I've used PhotoShop, Illistrator and DesignCad 3D since those early days for inspection reports and it still helps me express my self now that I'm not workin anymore.
The vacuum forming or actually vacuum bagging was something that I used the last half dozen years that I worked. I worked in a couple of the labs that made detectors for our accelerator and we made a lot of carbon fiber structures to go into the target areas. We used the same tecnology that the boat builder, car or air plane builders use and vacuum bagging the parts was a common practice.
Got a picture of the B&A of that YF 2100s on another thread. The W-1 is in the cooker right now for a soak overnight. When it comes out the steel parts go into the D-Rust-It tank for a few hours then they all get a good scrubin in detergent before the steel sees the fine wire brush. Finally all the passages and threads are all chased and holes plug. I hope the W-1 comes out as good as the YF did.
Gotta go make supper for my "big old wife".
