re your sharing group - Design Refs.
Thanks for sharing your thoughts.
For a sole proprietor / small bus networking is the only hope to survive.
if you need any Asme ANSI or API stds i have quite a few bought that i'd be
happy
to share if you are stuck. just ask and i'll see if i have.
(if I could afford a bulk pdf scanner i'd love to "paperless" my
office...even a little less would help.
cheers
