Can anyone explain the materials used in this picture. I got the picture from a different board and it seemed interesting.

Would the record actually play with the same quality as an original? Would it even play at all?

>> No.174951

Silicon mold and liquid plastic (might just be resin, but that seems like it would be too brittle for something like this).

If you actually got it right, the record would be about, if not exactly, the same as the original.

The problem is that unless you've been casting stuff for a while, this whole thing would be a lot of trial and error. The main problem would be bubbles. If there is even just a single tiny bubble on the playable side, you would have to scrap the entire thing, as there is no way to repair it.

Don't do it.
It is piracy.
Go assault ships instead.

It's wouldn't. It's a cast of the vinyl... So instead of groves it has the opposite... Like a partrouding line where the grooves would be on the vinyl

The pic OP posted was origionally posted from a German website, and a guy from the TV Show Pumkin Chunckin on Discovery Channel (and Catch It Keep It on Discovery) made a page where he translated the German webpage and responded to some questions and claimed to of tryed this out... I'm gunna see if I can find it for you guys...

Welp, here's the guys website... I guess he's also a writer for Wired Magazine too.

Very informational and has a huge/active forum going at the bottom of the page

Audio engineer here, and yes it would work so long as the red stuff (assuming it is resin) holds out. If you have a turn table, you'd probably need to adjust the tone arm calibration so as not to tear the new product apart.

Is it piracy? It's not really hurting the economy if you just want a few back-up copies of your favorite 45/33. I think it would be cool to experiment with different colors too, like make a rainbow colored vinyl, or make a clear resin and lay a photo face down as it's forming.

Goodluck if you decide to do this!

>it would work
Only if you can make the mold without and bubbles in the resin... And to do that you would need to make a vaccuum
Alot harder than it seems really...

Vacuum isn't required as long as your pour the resin in a thin and steady stream into the mold.

Bubbles are imminent, read the comments in the link I posted, brah

>>175576
put it on top of a washing machine and pour the resin, the vibrations will put the bubbles out

>> No.175629

it would not work, if you cant figure out why you are fucking retarded

>> No.175653

I think shrinkage would be a major problem with this idea. Also the 2 part resin (fastcast) does become brittle over time

>implying I don't know what I'm doing/talking about
I humored you and gave the comments a read

There were only two that mentioned using a vacuum. One was just commenting on how the maker of the tutorial used one, but didn't show that. The other was some guy saying that he used one at work.

Was I supposed to learn something?

my mother once tolld me they did this with chocolate, but I have no idea what you use for the negative
