since i lost my recipe that i had results with last time, i had to do a little trial and error to rediscover the solution
after some fine tuning, i'll start recording qty of materials and do a bunch of tests to get it working well. notes below
test notes:
started with glass of hydrogen peroxide, added sodium chloride until saturated. added more hydrogen peroxide until all sodium chloride was in solution. process repeated with soda ash.
no visible reaction was observed when placing test sample into solution. applying 8V resulted in bubbles forming at the anode and cathode. the test sample attached to the anode quickly developed pinnpoint corrosion, and the solution began to take on a rusty color
even after removal of the sample, the solution continued to generate bubbles and react. reaction eventually concluded.
removed sample had a heavy buildup of red and black oxide. wiping off excess and boiling the test piece resulted in mottled black oxide coat. pitting was visually apparent, but too small to be felt.
a second test piece was degreased and placed in solution. no visible reaction was observed upon its entry. applying 2V resulted in bubbles being generated at the anode and cathode. a thick, mostly even coat of black oxide with no visible red oxide was generated. upon wiping off excess and boiling, the final results were a durable but mottled and inconsistent black oxide coating.
No.1691
>>1690quick correction, at 2V bubbles are not forming at the cathode.
doing tests with test piece 3. keeping amperage between .1 amp and .08. when it drops that low i take it out and card it.
i'll have to investigate alternative carding techniques (pressure washing? liquid abrasive etc?) because the entire point of doings this is that the internals aren't accesible for traditional carding
No.1695
de-aerated some water and dosed it with sodium carbonate and sodium chloride
got black oxide development right off the bat. think my understanding of it is decent now
i think i have a rudimentary understanding of whats happening now.
next will brush up on chemistry… get the reactions written out proper like
No.1696
determining the region black oxide formation can occur right now
i did a test with sodium carbonate saturated solution and worked my way up with salt until black oxide formation was observed, then kept working up until salt saturation was observed
next i'll start with a salt saturated solution and hopefully i'll manage to get a condition where the oxide gets formed, then it'll give me a range of electrolyte solution that i know 'something' happens in
after that it will be a systematic approach of filling in data points and noting the quality of the coatings
No.1701
>>1699thanks the camera hides the flaws but it is pretty dark and durable
really very odd that theres nothing about doing this online. theres no way i could possibly be the first, right? just the first to document online?
just bizarre tho. hot and medium hot bluing are too difficult or toxic for people at home. rust bluing is extremely tedious, and cold bluing doesn't hold up well
you would have thought somebody would try to do this before

No.1704
>>1702gonna try and get the other bounding line tonight, I just finished working and I've got a couple hours before yeem get sleepy
after that I might try a test on a larger scale. Already made something to hold a trash bag, made out of chicken wire and wood plank stiffeners
see if this works on a 8ish gallon scale
No.1708
as an FYI the numbers above are range of 1-1/4 tsp - 2-1/4 tsp sodium carbonate and 3/4 tsp - 3.5 tsp sodium chloride in 1/2 cup of water

ok made a batch right in the middle of the range (1.75 tsp sodium carbonate, 2.125 sodium chloride)
i'm going to slowly increase the current now and see how if theres a range that yields the best results

No.1954
also i now think that the process is actually
>ferric carbonate (black layer)
>iron hydroxide (white precipitate)
are building up on the anode
when ferric carbonate is heated up it decomposes to rust and carbon dioxide
when it gets boiled its probably decomposing to rust, then immediately converting to black oxide
i'll have to take a torch to my test piece, see if heating it up turns it to rust or not. that will tell me if its iron carbonate or black oxide
No.1956
>>1955thanks i did my torch test today
i dont have a clue about whats going on, but its a dark plum color now which is also kinda cool. doesn't seem like its any less durable, doenst seem to be rust
i also did a test where i tried removing loose material with my hose on a new test piece in the backyard but it wasn't very succesful

No.1966
>>1964Oh you just mean what my opinion is on it?
i thought you were asking about my FAL build
practically, my preference would be all polymer. superior to wood in almost every way imaginable.
aesthetically, i think the west german's G1 FAL is the most attractive, with a mix of polymer or wood grips, wood stock, and sheet metal forend.
No.1968
>>1960all wood furniture usually only looks gud on ww2 era or earlier rifles imo
smgs assault rifles machine guns all that other extra fun shit should be either polymer or straight up metal unless youre going full artist autist and having everything engraved in which case wood can sometimes look
rally gud on something like a FAL but then you wont be doing anything but looking at it because at that point its just an art piece
part of the reason i hate classic aks is because the wood combined with the metal everything else looks fuckin stupid to me

No.1983
ok some pics will be going up soon from todays experiments
>the good
steaming works great
and the ultrasonic cleaner takes off loose material almost instantly (10ish seconds)
>the bad
i was hoping that doing more thorough cardings using the ultrasonic cleaner would result in not losing any coating during the boiling/steaming, but that hasn't been the case
since it doesn't seem to matter if i card in between electroplating sessions, im going to try only doing it after a boiling
plus i'll only do 1 electroplate session between boilings, since if its built up heavy 75% of it just seems to come off anyway
so the new method i'll be trying out is
>electroplate
>boil
>ultrasonic
>repeat

i'm still working on my stuff but its a nightmare, 1 of the 4 sections of my garage was poured with too much water by the house builders, so its very weak, spalls like crazy, and they had a bunch of wood chips mixed in with teh aggregate that rotted and left a fuck ton of voids
in short, i have a fucking ton of little repairs im doing and its holding me up
No.2495
>>2492why would there be wood chips mixed in i thought concrete pads were typically poured before any woodwork was done? idk shit about construction
No.2499
>>2495short answer, shitty builders
im sure the mix got contaminated. maybe a real windy day blowing debris from neighboring construction. maybe builder using a fucked up plank to mix, level, or otherwise work the concrete
anyway today i use some Sakcrete Top'N Bond
it's a polymer concrete mix that can be used for up to 2" down to skim coat
i mixed in some charcoal to make it dark **did too much tbh, shits almost black) and after chiselling all the cracks and cleaning i filled it in
shits kinda hard to work. after 3 hours i came back with the razor scraper to take off most the excess. next i'll use orbital sander with 80 grit to take it back down to base level
if the concrete wasn't so spalled it would look real clean with a dark fill like that (light fills always stand out like a sore thumb, pic rel. spalling is so bad it will probably look a bit dirty but i can live with that, as long as its nice and smooth
i'll probly do a second coat to cover that entire quarter of the slab. i still have other voids and other stuff to fill, and i might as well only do the sanding once.
No.2504
>>2499>might as well do the sanding onceYeah man that dust is a bitch once you get sanding. Imo that’s the best idea. Be sure to cover anything left in the garage with plastic or something really well to keep the dust off/out of everything. Lookin good so far keep plugging away

i did
>>2499 over the weekend but the top n bond has a bit of aggregate in it, so it didn't get any of the pinholes
i can slurry coat it and the polymer blend is actually so good that even with wayyyy too much water it still way fucking stronger than my current concrete even with only 12 hours of curing
No.2521
40% of my refinish sanded to 80 grit so far, can probably get it to 80% tomorrow
the surface was a lot less consistent than i thought, so the dark filler is wayy more prominent than i was expecting
not great but not terrible either. is buttery smooth, tho.
STILL can't get the pinholes, but i think i'm just going to leave it. only so much one can do, and i dont feel like purchasing a special slurry product

>>2521>pinholesYou talking in the conc? You can always get some conc sealer and run over it after you’re done. It’s better than leaving it exposed. You could always get mapai self leveling concrete and a gauge rake and over lay the floor.
