    Deciding this will be much like deciding if swordfish is kosher. Also like swordfish, my opinion is kosher. Bob's clearly not a spammer. It's not really his place to advertise someone else's...

    A double stem valve would be ideal. They wouldn't even require a linkage. Attach the back stem of valve 1 to the front stem of valve 2 with a rigid coupling. Back of valve 2 to front of valve 3....

    I can't help you with other systems. I used to use CATIA, but it's been so long I don't remember much about the measurement functionality.

    Do you have a picture? I'm having a hard time figuring exactly what you are looking for.

    I want to close off three pipes with the turn of a single handle. I'm looking for, essentially, three ball valves stacked on top of each other with a single handle on top. It seems like this should...

    edge gluing rough cut hemlock

    Any time you send a print/model to an outside vendor, you run the risk of it leaking or being used without permission. As far as the relative risk, I know that the smaller shops are...

    I'd be less worried about that with an automated system like these guys or protolabs than a shop where an actual human is involved and decides to run a few extra after work.
