Welcome Vacuum Experimenters!
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 places for more experienced vacuum
workers that seem to really get into the Physics of what and how the
molecules do what they do under low pressures. I've made a few
requests on some of those lists and I either get a full-blown snow-
job or an offer to sell me just the right do-dad for only a few
thousand dollars. That kinda leaves me without a place to chat with
folks that have some knowledge and are willing to share it.
I am interested in HiVac in order to put together an Aluminizing
chamber for telescope mirrors. I've been gathering parts for several
years in order to build my system and have a barn full of goodies but
was still looking for an 18 inch Bell Jar until last week when I
found a surplus 24 inch SYSTEM. I will be travelling to Eastern PA
this weekend to pick it up and will keep a running description on
here (assuming there is any interest and/or members). I've seen
Aluminum vaporized onto glass before and "it ain't rocket science".
It's a fairly simple process but there are things to be aware of and
to watch out for.
Let's get together and have some friendly discussions on what works,
what doesn't, things to watch out for, things to sell, trade, etc.
I'm moderator only in the sense that I've started this group. I'll
pretty much leave the daily running to the members but will step in
if I'm asked or if I see a need... other than that, it's your group
Have fun, be kind, learn, teach, participate.
