Aloha Mike,
Actually I have some staff for sale - Leybold A700 door vacuum chamber (Dia.700 mm x 700 mm) on the frame with assembled gate valve, three way roughing valve, LN2 baffle, and high current transformer for resistive evaporator, diffusion pump (Leybold DIP3000, inlet flange DIN250 specially for that chamber, manufactured for Leybold in Russia, brand new in unopened box, without heating cartridges), ULVAC rough pumping system (vane pump and blower assembled on a frame, looks good, filled with oil, but untested), and some other components - shields, feedthroughs, substrate heater for that chamber, etc... I can sale it all together for $8,000, but I have no idea how much the packaging and shipping from Southern California to Hawaii will cost!
If it is interesting for you, I can e-mail some pictures and more detailed specs. Also I have to check the status of all that staff because I keep it on my friend stock and haven't seen it a long time... :-((
Best regards,
Vladimir Chutko

Aloha group,
I live on Hawaii's Big Island and exposed to a very corrosive atmosphere (SO2/H2SO4 primarily). My 20" mirror needs recoating very frequently, and I am looking for a cost-effective alternative to constantly shipping it to the mainland coaters. I am not very knowlegable about details of vacuum coating, nor have the time to build, or funds to buy, a sophisticated apparatus.
My question is: Would it be practical to make a "simple" vacuum apparatus to achieve a useable Al coating even if the coating comes out "below commercial standards" due to insufficient vacuum, etc.? That may not be so bad, since I need to recoat it anyway every few months. I would appreciate any advice as to whether such an approach is worth pursuing for my unique situation?
Thank you!
Mike
