Yeah, I hear ya Bill. I may have just made a lifetime supply. But that's OK, I enjoyed the challenge. I think it's a better solution than the adapters I used to sell.
As a side note, it looks like I will be teaching a course in Hydraulics/Pneumatics this Spring for the University where I used to work. They've asked me several times to be an adjunct and I finally think I am ready to get back on the horse, at least for one class. I have a whole file of projects like this that I plan to show to the boss, I would like to teach a Special Topics course on product/process design for discrete part manufacturing. They have a place in the curriculum for it but nobody wants to mess with it.
