Re: weird Sharpie residue
Was the Sharpie a "dry marker" or a "permanent marker?" I imagine the residue from a dry marker would be carbon and that the solvent from a permanent marker to be much more aggressive. I suspect you

Moving up in chemical agression towards the dye would be methyl cloride..... or methyline cloride.... found in Dads Old Fasion Paint Stripper. ?Neither are caustic. Sent via the Samsung Galaxy Note?

Re: weird Sharpie residue
Guy, Are you sure the marker tip didn't in fact "polish" a groove into the surface? Some of the felt tip markers use fibre glass for the tip so it might be more abrasive than you expect. Just a

Interesting residue from a Sharpie or Magic Marker on a mirror that I cannot remove before aluminizing it! Here's how it happened: David C is making a 12.5" mirror and based on ronchi and

Re: First sputter deposition efforts
Andrew, this is great news and hopefully it will help me get up more enthusiasm. But time is a problem. As to reversing the wires - well it worked as it was supposed to do. And the cathode will be

Re: First sputter deposition efforts
Peter, I saw that in the youtube videos also but my setup did not allow for it so I did not do it. The round magnet is about 3/4" thick and the N35 magnet is about 1/4" thick so I could not really put

I believe I have eroded aluminum with plasma. The once shiny aluminum foil is now dull and pitted and missing in some places after 2 minutes of purple plasma. A bud tore apart a microwave oven and

Re: 36" Square Vacuum Chamber
If like me you would be shocked by the asking price of a vacuum vessel of a given volume, you might want to consider the virtues of a stainless pressure vessel rated say 10+ atmospheres, given that

Re: 36" Square Vacuum Chamber
If you mean new, 36" wide by 36" tall by 36" deep and made of stainless then you are looking at around 20 grand of custom build. Vacuum and large flat surfaces are not compatible so you may want to

Re: Magnetron sputter system
Also, adding softer metals between joining copper surfaces could help keeping the resistance down. Perhaps even help eliminating voids that trap gasses and other contaminants. I suppose tin or indium
