    Default Adventures in BLUE STUFF

    My blue stuff arrived! I opened it up, tossed most of it in a cup of boiling water, and a few min later I had a very hot lump of taffy-like blue stuff. Managed to singe my fingers a tiny bit because I was too excited to play with it. I didn't really plan what I'd cast, so I grabbed a container thinking that's something simple. Probably should have done something smaller for my first try, and I'm worried it will deform a little, but I'm excited to see how it turns out!

    The two remaining bars of blue stuff I didn't use.


    Here's the container sitting in the hot blue stuff waiting for it to set. Once it cools down it's still quite flexible, like a very soft plastic or rubber. Good for removing castings, bad for keeping perfectly square parts perfectly square.


    Container was pried out and a nice imprint remains.


    Took about an inch of milliputty and mushed it together. Never used the stuff before, wore gloves to mix and use it. Stuffed it into the mold, did my best to keep the mould from bowing out in the middle, and now I have to wait 2-3 hours. The blue-stuff is very quick to work with, but the epoxy putty I have to wait. Will it pick up all the detail? Will I be able to remove it without cracking it? Will I be able to sand the base flat enough to maybe use this as a background container? We'll all find out in a couple hours!!

    Excited to see the results -- I have a pack of Blue Stuff coming in the mail and thought about doing containers as well (they are stupidly expensive for what they are) but might also do some roof details that I was trying to replace that were missing on some built-up models I purchased.

    This looks like it might have a wide range of uses. Will be interested to see how it comes out.

    Where did you order your Blue Stuff from and how much did it cost you? Really considering using it myself for a few projects so definitely following this!

    Way interested to see the results! I've been making rubber molds of stuff I want to duplicate but it's extremely time consuming and overkill for one off stuff I'll never make more than one or two of, like lost model car parts.

    There was another thread on the topic and someone pointed out a source in Spain on Ebay (it was under $15). You can also buy a clear version on Walmart's page -- forget the name but it seems to be used in the same way.

    Yeah mine came from spain and the milliputty from wales. I just poked at it with a stick, pretty hard but I can make impressions with the sharp end, definitely want to wait the full 2-3 hours.
    The great thing about this stuff is of course that once you're done, you can just toss it in boiling water again and it's back to taffy. It also doesn't stick to its self when set, so you can make 2-part molds super easy.

    Uhg... maybe I should start with something a little smaller and more simple. The mold its self looks crisp and perfect, but I might not have pushed the milliput in properly. I'm also using the cheap grade, not the super-fine stuff designed for modeling...

    I wonder how a plaster of paris casting would work? Might help avoid some of those air bubbles.

    Good idea, this is a single-part mold, no reason I can't use a liquid.

    I also considered a 2 part plastic resin called Plast-aid. I've used it before and the stuff is AMAZING! Strong as concrete in just a matter of minutes and would probably take the details of that container mold really well. Only downside is cost.

    If I wasn't worried about cost I'd just buy more containers

    You do know that what you are doing may be illegal.

    Read the Anti-plug molding law:

    https://en.wikipedia.org/wiki/Anti-plug_molding_law

    If is a patented item then posting your efforts here may leave the site open to legal problems.

    If he were selling said copies that would be an issue but replicating objects for private purposes is fine. That law is based on creating unfair competition as far as I can tell.

    Well, right, obviously. It may still be cheaper than buying new containers, just not as cheap as milliput. The difference is I think it would give superb results (and really fast). Was also gonna say you might make a trough out of scrap wood, push the hot blue stuff in then press your molded object in. Then once you empty the mold you put it back into the block and can cram the putty in without warping the mold because the wood blocks won't give.

    Maybe you can start a container junk yard w/ built in weathering / damage -- you have some nice dents and tears there not to mention a big spot of damage from a bridge or something. Next to the highway near where I live there is a parking lot full of torn up containers -- drivers going under low bridges and such. Just add lots of rust and you are there...

    Lemons and Lemonade and all that.

    McNamee that's exactly what I was thinking, the damage is already there you just need to weather it!

    If containers were made of concrete it would look perfect, but aged containers don't really chip or degrade like a bad plaster pour. There's also weird lumps and bumps.
    I did another casting of some other objects last night using plaster of paris. Tried for more simple objects, some loads I got off ebay that someone obviously just cast them selves. I figure if the object was designed as a cast I could do it too. Still, similar problems, lumps, bubble holes, and more lumps. I'll get it eventually!

    For the container mold, if you have some Lego blocks you could build a mold "holder" of sorts with those and be able to pack in the epoxy and not warp the mold. I think you'll get there, just need to find a method that works for you.
