We get normally get good results after plasma cleaning if we get anything below 1.0e-4 Torr. We coat a few mirrors a month. This time we could not get below 1.7e-4 torr. Guy

Guy, Al coating performance strongly depends on vacuum and deposition rate. In general, it is recommended to evaporate Al on a cold substrate at pressures at least below 2x10-5 torr with deposition

Thanks for sharing Vaughn, nice setup. I'm also learning and gathering equipment. I have a gauge controller that I can't find any information about and will have to reverse engineer it to use. Can you

I decided to test my Veeco diffusion pump using the 1402 that I have just refurbished. At the present I am using my Web site for documenting my experiments, which I don't mind sharing; it is very

Howdy, Sigh...you're right. Here's a high-res photo of some gaskets: http://www.bubbasbarrels.com/sites/all/files/imagecache/product_full/aaDSC_2801.JPG They look mainly flat, with a ridged part

Please keep us informed of what you find, they do seem a fraction of the price of "proper" vacuum fittings. You make good points about trapped volume leaks and seals though. Hope they work out. The

The first issue I foresee is the o-ring material. If the seals are standard O-rings, great, then you can just order Viton O-rings. But I thought those fittings used custom seals with odd

On the gasket where the case parts split - is that RTV? There's no chance any RTV got inside the pump or any oil-wetted surfaces is there? I'm probably stating the obvious, but I don't think you want

Howdy, I've been a lurker here for some time - came across this recently and thought it might be interesting/useful. While looking for some info on brewing, I found these "tri clover fittings":

Yeah, you can't use anything even slightly abrasives to remove rust from any of the bearing/wiping/sliding surfaces such as shafts and vanes and valve seats and so forth. If there is pitting or a

... For rust-removal, evaporust is good because it dissolves rust instead of converting it like other stuff. It works better when warm > 20-25degC. Complete immersion or continu

I worked for an outfit who bought consumables and hardware from Duniway on a regular basis. Their staff are knowledgeable - at least the ones I spoke to - and they do not sell junk, as far as I can
