Sweet! Inter forum crosstalk. I still don't know what this is about but something is happening and I'm watching. Interesting. 3 parts what solid to 2 parts what liquid? John
sorry, its secret :/ Its sort of like a waterblock- think of it like that but for extreme cooling- and not water flowing through there
The cross-forum discussions are interesting, but sometimes I have to head over to xtremesystems to see what the heck Teyber is talking about. Sometimes the context is lost between cutting and pasting. The first time I read this thread, I was thinking "who the heck are these people that Teyber's talking about." Copy and pasting is okay, but without proper context, it's so not Cheesecake. So far so good though. I'm okay not knowing what the liquid plus solids are, but what the heck were you using it for? Polishing?
When brazing with oxygen acetylene, i will guess the evap itself is ~ 1500f, So hot it just gets disgustingly black. Do you see how black and ugly the top of the evap is in teh last pic? Well that doesn't sand off. I cannot say what is in the chemical i have made up but it breaks down the black stuff so i can sand it off or even use a rough sponge and get it off... If you look about 2-4 updates ago you will see a brazed evap with the silver top, thats what it makes the UGLY top look like i would tell you how... but then people would guess my secret potion reed
You won't tell us what the chemical is, or don't know? If you don't know what you're dealing with, you had better find out! An unknown chemical that can break down a surface that cannot be removed by mechanical abrasion can NOT be good for your health. There are many nasty chemicals out there that can do you harm.
oops- no its a mix of things id rather not say in public- but its basically a couple different acids and some other random items
I guess I understand, but unless you aim to secure a patent for it, or wish to open an evap-fab business, there's no reason why you shouldn't divulge. Since OSHA deals with occupational environments, they've got no problem maintaining a 200 yard minimum distance from Teyber's shop.
As far as I was aware, this was your first; I don't recall seeing your previous prototypes in action or under testing. Divulging your secret recipe isn't going to stop competitors from working other angles. Also, bear in mind that there are tried and true techniques for prettying up copper. I seriously doubt that any of your "competitors" will steal away any business from you by using your technique. If your secret recipe is unique to you, then what's to stop a competitor from learning tried and true industrial methods? If your secret recipe is based off of industrial techniques, then there is nothing to stop competitors from learning the same methods. We're just curious as what you're using, that's all. Take a look at project logs by Bill from mnpctech. They mod cases for profit, and design parts for sale as well. They have many, many competitors, yet Bill offers detailed info in his project logs, shows video of the fabrication processes, and answers the many prying questions that the modding community asks. ANYWAYS, it's been three months now, get to finishing up, chop chop! =)
Teyber, I only asked because I have a Ford flathead engine that really needs some scale removal on the water pumps. The Hot Lye Soak technique hasn't worked too good so far. Industrial secrets are meant to be "secret". Still cool work. John
the components are- citric acid white vinegar Flour lots of salt something called "bartenders friend"(used as a abrasive) a rough sponge sand paper stuey- This is not a phase change build log... this is just where i post my evaporators i make for myself or customers. More updates are to come on naekuh's phase change (one of the top threads under "my threads" option) if you like to see ice
*shrug* I thought it was an all-encompassing worklog. I dunno. How did you select the components for your polishing mixture? Bartender's Friend is a stainless steel polish, I know salt and vinegar can be used for cleaning, but flour? Hey, if it works, so be it! You did clean the copper up pretty nicely.
thanks basically the salt and acids break down the oxidation and the flour, and bartenders friend work as abrasives with a very rough sponge. thanks for the praise
Boiling lye is a good solvent for aluminum but it doesn't affect steel. (At least not ansi H11 or H13!) A soak leaves a layer of NaOH. It doesn't air-dry well, but after some time it forms a brittle white frosting. It can be scraped off but at work we use sandblasting to get rid of it. Sandblasting also takes care of other soot that isn't affected by the lye. Glass bead sand work nicely and doesn't harm the steel.
i couldnt help but turn your kitty into a lolzcat Teyber. also long time lurker first time poster, you do some amazing work man
