If you can find a (musical) instrument repairer, ask them what they use as a laquer on their brass instruments. It's tough, and the brass doesn't oxidize even after several decades. (It cost a friend an arm and a leg to get a second-hand horn repaired and relaquered, but he was told most of the cost was labor for removing the old laquer before polishing and recoating.)tcurt wrote: Also, I am brushing the copper with steel wool to shine it up nicely, is there any kind of coating that can keep it that way? Online searches seem to be dead-ends with them all telling me to soak it in vinegar once in awhile. I am looking for more of a varnish.
Maybe use something else here and save this one for a cyberpunk build?tcurt wrote: ↑August 29th, 2018, 6:56 pmBut in the specific case of the silver fittings (Nickel-plated Brass I believe) that is on purpose, the aesthtic with the pump and reservoir is clear/silver to contrast the brass/copper fittings all around it. At least that was the idea, so far no one really likes it but me. An artist friend of mine even asked if something could be done with the sterile/medical style pump. Problem is it looks so COOL.
I am considering finishing it with an amber/resin look but then the reservoir stands out. My plan all along has been to play with lights perhaps I can add some yellow/red LEDs around them.. but that block is going to be clear and non-diffuse so.. perhaps sticking a bunch of copper tape to it? Blah.
It is purely cosmetic. I have a thermocouple in direct contact with the coolant for actual temperature.FishPreferred wrote: It also has the problem of being an atmosphere thermometer in an application with asymmetrical heating. If you want to measure the device's own temperature, you need something that can act as a calorimeter.
