Dear Ken
Sure would like to do some vacuum deposition or coating...I have four retorts that are 5 Ft. Diameter X 9 Ft. long and they are just sitting there waiting for me to do something!!! Lots of little pieces to put together. Have done some coating on a lab scale and have seen some really big systems over the years but now I want to get into production. So where do we go from here? Bill Lang..Stockton, CA |
Some of the posts have been vary helpful to me,?I?shut down my shop because I decided to retire and get a real job so all of my stuff is buried in storage. Ill be finishing the chamber as soon as I make a spot at my house to put it. Maybe even make a new one. ?My new job comes with all sorts of machining and welding capacity. If the group doesnt require a lot of work, keep it open, sometimes some neat stuff comes up, If you want out of the moderator job perhaps I can take it over for you rather than shut the group down. It would be nice if there were more members to share info with, right now my vacuum project is on hold but Ill be getting back to it soon and I know Ill need some help when I do. Part of my job is working with some vacuum industry manufactures and these guys can be a great resource as well. Regards, Ron White PS good luck in finding a new place, I AINT never moving to much work Ken Hunter wrote: What a boring group! Can anyone give me a reason to keep it going? |

Those pumps must be huge to suck those tanks down to -6 or so!
I have a 30" +/- inch dia tank 3 feet high and wonder if my Diff pumps can do the job... I'll get to try it if I ever find a house here in Amarillo.

Looks like I stirred up the pot again...
I read the History of Vacuum several months ago and recommend it highly! As far as giving up the moderator position...??? There's nothing to moderate, so far it's the easiest job I've ever had! Keep us informed on any goodies that you run across and don't forget that it's perfectly OK to post FOR SALE or WANTED items here.

I would certainly suggest using multiple vacuum pumps. A "roots" type centrfugal pump will get you started and then maybe a liquid ring vacuum pump then your pump should do the job. The new refridgeration pumps will get to 50 micron. I am gathering all these things at tis time also.

Can anyone give me a reason to keep it going?(just found this msg, since I just joined) Well, given that it's a somewhat specialized field of interest, and stumbled across it quite by accident, you might need to allow some time for others to do the same, or find a way to promote it. Have you posted anything about this group to The Bell Jar? I mentioned your group to two others, and will probably also post it to a couple of other mailing lists I'm on. |

Hi Bill,
Thanks for stopping by and joining... I searched and searched for a forum and found the Bell Jar too... seems they are on a "linear track". They started out simple and progressed to complex in short order then for all practical purposes disappeared from the net. So I strarted up this group. Participation goes in spurts and I have to stir the pot every so often to get some posts on here... Not really thinking of pulling the plug. ;o) Ken Hunter --- In VacuumX@..., "Bill Lemieux" <gomez@o...> wrote: --- In VacuumX@..., "Ken Hunter" <atm_ken_hunter@y...>wrote: going?What a boring group!

I thought The Bell Jar was sort of a internet tie-in to the paperI haven't kept up on the Bell Jar as they were heading into deeper water than I could swim in and had progressed to projects that I wasn't interested in. I'm hoping that we can keep this forum mainly for the beginning vacuum enthusiast. It surely doesn't hurt to have some of our members that are well versed in the details and have years of experience in vacuum work though! They are a great resource but I find that the other web resources I'm finding are mainly for PRO's with deep pockets. For instance, on one forum I asked a question about glow discharge cleaning and got many replies from folks trying to sell me hardware with beginning prices well over $20,000. I probably won't have $20,000 tied up in my whole vacuum coating system (including the cost of the building). I am a beginner, a novice, it's a hobby and I'm just NOT interested in what happens on the sub-atomic level or in using calculus to figure the details for multi-layer coatings. I just want to make the glass shiny! Ken Hunter |

I went to an auction in Boulder for a company that had made micro-electro-optic devices, and they had a number of plasma cleaning devices that they had home-made from microwave ovens, home-brew acrylic (!) chambers and other such stuff.
