Where's the current list of stuff available? Thanks. -- Nick A "You know what I wish? I wish that all the scum of the world had but a single throat, and I had my hands about it..." Rorschach, 1975

Hi, I dont use this group much, but I have had some really useful information in the past - so dont shut it down. My interest in vacuum stems from power cable manufacturing processes. I have been much

Ken, With the demise of the Space program ( for reasons unknown to any of us in it ) I have been really hitting the mirror business. I now have full up production capability for foam glass fusion

Hi Ken, Just plain been too busy with other things, like college.... Most of my life is now back in boxes so I can keep my focus where it needs to be, on my books. Still able to run this group so long

Ken, What sort of mechanical pump do you have? and do you have any oil for one? Guy Brandenburg, Washington, DC http://gfbrandenburg.wordpress.com/

Please don't shut it down. I learned something on it recently that made aluminizing mirrors with our old surplus vacuum chamber much, much easier. Guy Brandenburg, Washington, DC

I haven't done any vacuum stuff yet because i'm too busy. I like to have this group to use later on though. I'll try and store away any unwanted vacuum gear but i'm probably a long way away.

Please do not close the group. This is the only stage where wone can get basic to advance knowledge on vacuum Regards Zafar Iqbal To: VacuumX@... From: christopher.k.erickson@...

Don't shut the group down! If you don't want it, transfer ownership to me! It is the only forum on vacuum technology that I have found anyplace. -Christopher Erickson Telecom Engineer Waikoloa, HI

It's been a while since we've had any activity on the Group. Should I shut it down? Anyone interested in the rest of my stuff? Pumps, baseplate, valves, gauges, ION tubes, Gauge controllers, etc. I am

It might be worth a call to the University of Hawaii’s thin film lab - http://www.hnei.hawaii.edu/thinfilms.asp. If nothing else a chance to tour and look at the equipment will give you a better

Right now I think that my calculations put me someplace between $20,000 and $50,000. I don’t think many people are going to be prepared to share a meaningful percentage of that investment.

Chris, Maybe we just need to build a coating system to be shared by all of us on the big island? I saw the posts quote from $8000 up to tens of thousands for the needed equipment. Maybe if we look

Well, my scope is a truss style Newtonian, all open. Your approach would mean building a whole new airtight N2 sealed telescope... or at least optically sealing the primary mirror. Due to cost and

Just a thought. I have not heard this discussed before here or maybe I just missed it. I know that you guys want just the purest optics possible so this idea may make you gag but I work at Cape

Thomas, I was worried you got flooded out or something. How goes down under ??? Mike, I do have a 1.5 meter vacuum chamber. I started with a NCR chamber so don't have a build plan to offer. The door

I have been doing the numbers and trying to decide if I want to build a 1.3 meter coating chamber here on the Big Island. Doing the financial math, a 1.3M chamber appears to only be about 40% more

Aloha Mike, Evidently you must live down wind of the valcano. I have been to the big Island twice and had a wonderfull time both trips. It is a very interesting place in many ways. All the coating I
