Mike, sorry it's been so long since I logged in. The services they provide are largely in duplicating parts, not engineering parts. If you have a part which could be duplicated in a better grade of steel, for example, I had originally fabricated a claw mount in aluminum alloy--then they can hand you that part in tool steel. Any part which can be accurately blueprinted on computer they can make as well. Your research will uncover more data without a doubt. Steve
