give hamilton machine a call. i have no idea what they're certified in, but they've done some very nice stuff for me in the past.

also, i believe gk2004 still has his connections at the place he used to work.

This is for an adapter collar for some mixing vessels that we're incorporating into a formulation isolator for a pharmaceutical customer. The current collar is a metric DPTE Beta to mate with a DPTE Alpha port/door assembly (for transfer of pharmaceutical/biohazard contents). The other end of the collar has a 4" Tri-Clamp type connection, but our vessels use a 3" connection. Due to the nature of the product and its intended uses, these collars cannot be returned; besides, they are about 2000 dollars. So I'm looking at having them machined and having 3" Tri-Clamp sanitary connections welded on. The assemblies will then have to be polised to at least 150-180 grit (25-30 Ra).

The major assumption is that we need to have a pressure-vessel stamp on the revised pieces, but in reality, it's looking like that's not going to be the case, as the original adapter collars have no such certification (this is upon further scrutiny). We can handle this in house if that's the case.

None of my connections or contacts have been able to supply such certification, but it's looking like we won't need to worry about it. (This includes a few contacts in my very own home county of Johnston, as there are several machine shops that perform work for Bayer, Pharmacia, Novo Nordisk, etc., in the pharmaceutical field).

My place closed in Dec 07. I was going to recommend Bolton. I can still do CNC milling jobs at a friends shop but have been for the most part out of the loop for over a year now. I really miss it sometimes and hope to have some equipment at the house in the next few years. Breaks my heart to see my Kennedy tool box with the 13 years of tools and gauges tucked away in the corner of my garage but cant bring myself to sell any of it either. Im thinking of trying my hand at gunsmithing sometime in the near future. I still have the design and CAM software on my home puter so I can still draw up stuff for myself and friends.
