Hi, Coating uniformity depends on substrate holder type (single or planetary rotation), chamber dimensions, evaporator position, coated surface shape and some other factors. For industrial coating

Hi, This is my first post in the group. I want to know the tolerance in thickness variation (in nm) of Aluminium coating, acceptable and expected from professional and amateur coaters. Mr Jan van

Hello Thomas. I'm right there with you on that. Oddly, I don't think I've ever even posted to this list...I've been lurking for a while though. I hacked with some vacuum stuff years ago; I have an SEM

As I said to Ken earlier today, I'm happy to keep on being a part time moderator/owner as for now the group seems to be just about running itself, so if we can keep that happening then I see no reason

I have just added another moderator to the VacuumX Group. David McGuire, located in Florida USA, has expressed an interest in keeping the Group running smoothly. Currently Thomas Janstrom in Australia

As Javaguy mentioned, I have sold the diffusion pump stacks, roughing pumps, baseplate and misc other items. Will be delivering it all to him in a couple of weeks. I have listed several small items on

Just made a deal with Ken to take the rest of his hardware. It will give me a great head start in getting my own vacuum chamber built. Thanks Ken.

Thanks Ken.Ed ________________________________ To: VacuumX@... Sent: Fri, March 25, 2011 3:39:29 PM Subject: [VacuumX] Re: diffusion Hi Ed, I think the 6 inch is a CVC, I'll look to see if

Hi Ed, I think the 6 inch is a CVC, I'll look to see if I can ID the 8 inch. Ken

Hi Ken what kind of diffusion pump do you have and how much.thanks ed edsworkshp

Javaguy, I have a HyVac-28 and a Welch 1397 roughing pump. Both are in good operating condition, a little dirty from sitting in the barn for a few years and the oil is needing changed from absorbing

Thanks, If it were possible, I'd deliver it to you. Ken Hunter

Paul... I have 2 diffusion pump stacks available... 1. (bottom to top) 6 inch diffusion pump, cooled chevron baffle, electric controlled pneumatic gate valve, electric controlled pneumatic roughing

Yes, I have 2 roughing pumps, a HyVac-28 and a Welch 1397 available. I have 2 gallons of Vacuum Pump oil I got on eBay that will go, one gallon with each pump. I thought we had this conversation

What kind of roughing pumps do you have and what condition. Would you be able to pack items for shipping. I live in Oklahoma, but it is a little too far to drive.

I would have made an offer if I was in USA.

What are you asking for the diff pump? -- Paul Anderson VE3HOP wackyvorlon@... http://www.andersonloco.com

Did you have any roughing pump oil? I don't think it's worth my while to drive out to Illinois given that we have a working system here. Except: did you have a working mechanical pump?

Still have the diffusion and roughing pumps, valves, etc for sale - What no offers? Ken Hunter

I stumbled upon this group when I was searching for MgF2 coating service suppliers. The whole vacuum coating technology is amazing, I hope I can experiment on this one day. Here is my question: any
