Greetings All, Thanks to Peter Baird, I've added the option in my simulation code to support multiple evaporating rings. An interesting result from this experiment shows that it should be feasible to

Hi Darald, James is the ONE to ask about silvering... He has done quite a few mirrors that way and I believe he's made a few attempts at coating them to prevent tarnishing. I'd bet that he can give

Hi James, Thanks for the informative post on the Capillary tube usage. I don't know much about those things but I'd have to guess that the capillary tubes I have are about 6-8 feet long (in a 3 inch

Greetings All, To stimulate a little conversation, I thought I'd recount a few of my more "Exciting" moments during a few recent coating runs :) Good Times #1 Things were going well, but perhaps it

Thanks Andy for the Bio and info on your job... Hmmm, working in a foundry sounds interesting. Bet that you'd be able to make your own forks for a fork mount there??? Yeah, I hear you about finding a

Hi Ken, Interesting question, unfortunately the answer has a whole bunch of variables! So here's my stab at an answer. The Cap Tube size/length needed depends on the following variables Pump Volume

Ken ; hello I work in a foundry, Im the lead calibrator technician, we have 5 small units we use to pull up to 30 lbs of vacuum to test for gas in the aluminum.Calibrateing them is pretty straight

Hi Andy... Welcome to the Group. I'm sure that your expertise can be of help to some of us as we muddle through. Where are you located? I'm thinking Australia for some reason. (Am I close?) Tell us

Ken ; hello , just joined your group , I confess I dont know much about vacuum coating mirrors, thats part of the reason I joined.I do however calibrate vacuum gages at work for a liveing.So if I can

Hi... It's been a while since anyone (me) posted. We now have 12 members, but not much participation. Should I keep the Group open or let it die? I've returned from Eastern PA with a vacuum coating

I've added James Lerch's web site link to the Group Links. If you have a web site that you'd like to add... please do! Ken Hunter

In James Lerch's system he uses an adjustable valve to "tune" the amount of cooling derived from an air conditioning compressor to cool his cold trap... I have a similar cold trap (3 actually) that I

Hi Guys, I'm heading out the door for a 4 day fishin trip, but just wanted to say Hi! BTW, Ken I love your "Junque Shop" :) Threw a couple images into the photo's section. I have many more images on

Hi Guys... I've posted some photo's to the group in a folder named "Ken's junque shop". There's one of me and a SILO top that I have been lugging around for a while, a few of some vacuum valves,

Gee... I sure hope I spelled that right! Anyway, Welcome to this new Yahoo Group for the casual experimenter in Vacuum or High Vacuum (from now on Vac or HiVac). Searching the web I've found a few
