Greetings, I'm already subscribed to your channel, I just have a question... can this process with silicone be done on a plasticine figure?

[@susanchurch3974]

This is your friendly sculptor who has worked above a foundry for 15 years. When you are trying to weld any piece of bronze to your sculpture after casting (i.e. fixing the tail) use an alligator clamp fixed in a weighted base to hold your small piece in place while welding. It’s secure and unaffected by heat. It’s called a third hand or strong hand.

[@lundgrenbronzestudios]

That’s a good tip. thanks!

[@robinson-foundry]

That's a lot of work! Nicely done!

[@JohnJones-oy3md]

Mold-making definitely is a bit of a black art. Nice sculpt, BTW.

[@Mistertbones]

Nice start. Can't wait for the final result!

[@cindylundgren1924]

A few scary moments ... but you got through it! So happy it turned out for you!

[@walterm5878]

Finally I could see how to make a mold with plugs. I have some pieces out there for long time waiting to be molded and could not figure out how to do it. Thank you for showing us the path.

I'm slowly learning the basics. Today, I realized that you can't use plain air clay with platinum-cure silicone! Sulfur additives in the clay don't let it set and you get slime! (Cure inhibition) Oh well, at least it was on just a small mold, and now I know!

[@mrllblasi]

Excellent vid! Thanks for sharing your adventures in mold making.

[@rgb9795]

thank you lundgren!

[@StarrStudio66]

Nice job. Complex molds like that take allot of ibuprofen(for the headache) to get thru lol. You got it done and done right.

[@dalehallmark9174]

I work as a geoscientist (Groundwater Hydrology) and love everything Geology. Since you do Geology maybe do a miniature Geology hammer/pick in bronze. Maybe 6 or 7 inches and proportional. Might be a fun project.

[@michellemwina6051]

Making mold and casting is always challenging,

[@DragonAtelier]

Woah! 😳 damn brother! That is freqking amazing! I keep my fingers crossed if I can get to the place where you are now. At this point I just make slurry shell onto my 3d printed patterns. Your way is a lot more challenging! Good job!

[@joshlintula9457]

Very nice!

[@MichaelNielsenStudios]

awesome

[@engashrafhesen7127]

Good working

That beast is an American beauty that one could gaze at in wonder for hours! Possibly incorporating a core into the pattern to reduce overall weight as an alternative mold, not that the mold making process is not already complicated enough. Just looking at the Bison, I think a parting line for the core could have been done vertically where the fur and skin join mid-section, then welded two halves together(only a random thought, no clue really). Your mold design may be better since the bison is big but not huge, plus won't have to deal with welding. I am sure there are many other molding methods too, and also sure your end result will be another American Masterpiece !!!

[@lundgrenbronzestudios]

It’s already bronze. I’m happy with how it turned out. That will be next weeks video.

[@mevk1]

SWWEEEEET

[@jinerhugorodriguez7205]

Ok muy práctico felicidades

[@MariaPerez-ig6dx]

I’m learning a lot from your videos, thank you!!

[@bartcubbins3528]

Very cool! As always Love your work and style 😎 keep it up!!! ! What type of wax do you use? Also could you please do a quick refresher on how you do the hollow casting?

[@lundgrenbronzestudios]

The next video will be the casting of the bison so you will see how I set that up.

[@noviceartisan]

Great video as usual dude! I was SO cringing when I saw you adding platinum cure sililcone to the tin cure haha Knew that was gonna happen xD

[@noviceartisan]

As you've gone to the effort of such a good mould, will you be making a whole 10+ tree of these at once? :D

[@lundgrenbronzestudios]

If only I had a flask big enough. Right now I can only fit one at a time. But I did just buy a perforated flask for vacuum casting. I’ll have to build a vacuum casting set up though. But that should help the quality of my casts.

[@noviceartisan]

@@lundgrenbronzestudios I built my own vacuum chamber using simple steel pipe, and some steel sheets. One on the bottom held onto the pipe with cheap gasket glue, top one is spot welded and gasket glue for safety, as it popped off a few times when I was removing the flask without the tack welds. The top piece has a circular hole in that I drilled using a drill press (normal drill would work) and a hell of a lot of drill holes 😅 then filed down to be a closer to circle. (Guess an angle grinder may be easier to do it with if you've got skills) The pipe has a hole drilled in the side of it with a vacuum hose fitting thats sealed with PTFE tape on the threads and more gasket glue. I cut a gasket to size from silicone sheet using a craft knife too for the top surface between it and the flask :) Works a charm and cost me next to nothing. If you ever get a blowout and the metal leaks, it's easy enough to pop the bottom off and free the metal once its set and replace it with no hassle too ☺️ Can share some pics and build pics if you need to see them to get a better idea.

[@mevk1]

@@noviceartisan Fascinating. I would love to see a documentary youtube video of the build with a few pics and maybe a drawing with some notes. Anyhow congratulations.

[@lundgrenbronzestudios]

Yeah I'd love to see some pictures of your set up. It's good to hear that gasket glue is enough to hold the seal. I was wondering if I needed to weld it but I'll just tack it like you did and glue the rest. I have a pipe and some plate steel.

[@jeetendarkumar4514]

You have impressive knowledge about making molds that's level like a professional mold Master keep growing bro 👍would you thech me ? Plz 🙏

[@lundgrenbronzestudios]

Oh I’m no pro. Haha. I drive the struggle bus every time. 😆

[@chadburud5681]

Nice work.. no America speech today? Lol

[@lundgrenbronzestudios]

Haha. Not today.
