I think im going to move to PA!!!

But alas its a long way from New Zealand.

I myself am a lurker, and not messaged within this group before, im collecting pieces to build myself a telescope sputtering chamber, so i joined to get tips and to learn from some rather experienced individuals.

Im almost there, all i need is a diffusion pump and either a 14" bell jar or a tig welded stainless chamber, but getting hold of pressure vessel heads here in NZ is nigh impossible as with almost everything i am interested in...so its custom spun heads or a bell jar, both qiute expensive.

I am so enviouse of the surplus shops and brick'a'brack junk shops you have in the USA, i tottaly would jump in my truck and travel interstate to pick up an old chamber or bell jar, the adventure of driving tot new places and to pick up some "science gold" at the end of that rainbow is intoxicating. nerd-vana!!

List owner here....

So where I'm at: I donated my vacuum rig and mirror grinding gear to a local observatory and am now a semester out from completing my MD degree....

So if anyone wants to take over the group and migrate it to another platform, please hit me up, I would hate to see the archive of knowledge disappear!

Cheers from Down Under.

Check this out!

FYI this guy is pretty sharp. You get get along with a chamber made from a propane cylinder. He also has built a bigger system using carbon steel plate and a welder. Try to get creative. Diffusion pumps I think are on ebay a fair amount.

nope...we have Trademe.co.nz but its way over priced for second hand stuff and very rarely anything interesting turns up...when it does they want full price someimes far more than if it were new!!!

i do buy ebay usa though and europe...i recently got a really cool Depostion controller, it measures and monitors the thickness of depostion coatings for 200 bucks! really neat kit.

A VAC chamber form a pressure vessel?? i thought that wouldnt work and they are designed thin but compound to resist burst pressure rather than vacuume.. i cut one open myself and it was 2.5mm thick not enough for a vacumm. maybe 4mm mild steel right?
