Brilliant use of everyday items! Bravo!

[@GEOsustainable]

Thank you. I try to keep things down to what folks actually may have in their home, and minus the $100,000 in workshop tools.

[@edgarandres7410]

You prolly dont care but if you are stoned like me during the covid times then you can stream all of the latest series on InstaFlixxer. Have been streaming with my brother for the last couple of days =)

[@alexanderronan33]

@Edgar Andres Yup, I've been using instaflixxer for since december myself :)

[@TheGrandFanelli]

Fantastic! Thanks for including everyday objects.

[@GEOsustainable]

Wonderful to read your comment. Yes, if you can't make it, it is of no value to you. Not everyone has a tool shop. One of my goals is to present subjects anyone can do from the kitchen.

[@hardkrome5050]

I make molds for casting resin. I tried this. 1 tube of silicone made about 24oz of silicone after adding a lot of NAPTHA. I poured a two part mold. I had to add the corn starch after I thinned it and pulled a vacuum on it to get the air out. Wax the part and brush vaseline on it and the other silicone half.

[@GEOsustainable]

Thank you for sharing your method. I am pinning this to the top so others can gain from your help.

[@hardkrome5050]

@@GEOsustainable Thanks, One other thing with a 2 part mold, is that you have to make each half the same thickness. That way when shrinkage occurs both pieces will match. The poured ends of each half of the mold have to really be thick.

[@pawandev23]

Thank you for such a detailed explanation and a lovely experiment. I am going to try this process out as it seems to be easier to begin making vascular phantom models using optical silicone or sylgard 184.

[@GEOsustainable]

That is a GREAT idea. Let us know how it turns out.

[@danpestana9459]

That was more brilliant than I expected.

[@GEOsustainable]

I'm so sorry. I will try to raise your expectations in the future. LOL. I am glad you liked. I hope you come back often and watch my videos.

[@danpestana9459]

LOL. My expectations were low for the actual amazing result that could be achieved by a silicone extruder, not for your abilities; I was neutral in regard to that, having not seen your channel before. And, I wanted to make a custom silicone tube (square shaped) and was very thankful that you showed me an easy way and indirectly gave me an idea of how to make one.

[@lindabadenhorst8721]

I'm obsessed with your videos, please can you figure out a plastic clay for molding. I saw they use grout as the powder and baking soda but the rest I'm not sure if it is glue or paint mixed with fiber. Thank you for sharing your experience with us.

[@GEOsustainable]

I am so glad you like. I will be glad to develop a clay, or figure out what that mixture is.

[@TheDuffman1986]

I love your videos, very informative and you simplify everything! Iv been trying away of using normal silicone and putting it into a mould to create a fishing lure, Iv made rubber and plaster paris moulds, possibly adding colour, glitter etc to the lure! What are your thoughts or is it even possible? Thanks from Ireland….Padraig

[@GEOsustainable]

Thank you for your kind words. I am happy to hear I keep things simple, simple is good. Lot's of folks use my techniques to make fishing lures. For your mould, I think plaster will work better than rubber. I think silicone will stick to rubber. And plaster is easy to shape. Glad to hear from a fellow fisherman, I should do a video on lures. Greetings from America to the Emerald Isle.

[@85krink]

Thank you for the video! Do you have any idea on cure times vs silicone thickness in regards to the pourable silicone? I am making a 2x4 shaped mold that is about 3 inches tall and I am worried about it taking forever to cure or not curing at all.

[@GEOsustainable]

Glad you enjoy my content. I have solved that problem as well. Watch this video to see how its done. kzbin.info/www/bejne/e5CsgKSumdhkaZI and here kzbin.info/www/bejne/hZOcimqpn65nf6M&lc=z22zxxcqfrysunu0qacdp435gmliy2bd01rurwazwg1w03c010c

[@nonameishere7234]

You're a genius Thank you sir =) Can you tell me roughly how long does it take to cure for a thinned and poured silicone cast. Knowing that it is poured in a cube shape mold with 2 inch edge. And maybe it would cure faster if i poor multiple layers and let them cure in between

[@GEOsustainable]

Cure time depends on the thickness. Anything more than 5mm will not cure unless you add moisture (water). Water is the catalyst. Adding cornstarch is an easy way to control the moisture. Cornstarch loves water. In my series on silicone, I use cornstarch and in this video, I squeezed out my tube in a solution of water and hydrogen peroxide. As I cover different methods in each, I encourage you to watch the entire series, and stay tuned for a new one I am currently making on 'thin pour for pouring a thin sheet'.

[@nonameishere7234]

@@GEOsustainable thank you very much for your fast and clear response

[@donmichaelcorbin4417]

For a more uniform tube, you should try using a battery powered caulk gun. It'll provide a steady dispensary rate.

[@GEOsustainable]

I love it! Yes. My wife just ordered a cookie maker, I was just looking at that. Battery powered caulk gun is perfect. I did not know they existed. Cool.

[@ihtsarl9115]

I give you a like on this video v good idea using peroxide

[@GEOsustainable]

Thank you. More ways to cure silicone is coming soon, as I experiment, I have made a few new discoveries. If you have interest in silicone, my latest video for making silicone that can be molded to skin and plastic is here. kzbin.info/www/bejne/eZqVaYxpj5iVj7c

[@jorgemartin7697]

Hi friend And why don't you put a nail or a screw directly in the center of the plastic nozzle, of the silicone outlet??? thus , it would come out directly in the form of a tube greetings, good job

[@GEOsustainable]

Did not have either one handy:)

[@darkfielddiggermicrosafari]

How will you attach the nail inside the nozzle?

[@stupid-handle]

Any ideas on how to reinforce it so that it would support moderate air pressure?

[@GEOsustainable]

I have the same problem. I was able to solve it by making it much more thick. That may not work for you. You may need to add reinforcement ribs.

[@aryanprivilege9651]

What’s use? Polypropylene, pex hell vinyl, airline ids dirt cheap, use liner, coil, zillion ways. For chemistry, air gas N2 corrosives. End use? PVC can go to 1000psi depends pex if insane inert 100 psi rate. People higher, grades vary. Vacuum or positive. Positive tons out there.

[@jorgemartin7697]

a question How does corn starch affect to the mechanical properties of silicone? makes it more fragile stronger?? or what??

[@GEOsustainable]

I don't use much, so the mechanical strength I am sure is fine. If you use a lot, it will cure before you mold it. I am sure there is a limit to how much before you lose bond.

[@mahela1993]

What does the hydrogen peroxide do?

[@ViktorBludov]

what strength of hydrogen peroxide are you using? thank you for your time to share your knowledge

[@GEOsustainable]

I use 3%, straight from the bottle. Thank you for your kind words, it inspires me so much.

[@ViktorBludov]

@@GEOsustainable im not sure what i did wrong with hydrogen peroxide in water proportions, the silicone was still tacky and stuck together. I tried using a dish soap with water and it worked. How long do you wait before taking out the tubing from peroxide solution?

[@user-qc4xf8xg1s]

I have a question, please. When I added naptha to silicon And I mixed up. Silicon turned into liquid, but it remained liquid and didn't dry out, and it had cracks. What's the reason?

[@GEOsustainable]

It is difficult to know for sure, so I will go over a few things you may habve missed in the video. Use ony Silicone that 'smells like vinegar' when you open it. Do not use too much Naptha, at most 1/4 of the total volume. If you pour it too thick, it will never cure. To cure a thick pour, add 1/10 of total volume of Cornstarch. I hope this helps. If you have trouble, let me know in the comments (new one so it sends me an alert), or you can email me (email in the description.

[@Wang-yg2ge]

Thank for sharing! I have some questions, what is the ratio between H2O2 and water? I want to make a really thin tube what kind of material would u recommend Thank for ur reply

[@GEOsustainable]

My pleasure. About 50/50. I work with the white for very thin.

[@Wang-yg2ge]

Hi, how long should it stay in the H2O2 to form a shape

[@YerroPhunder]

hey im wondering how much shrinkage there is from using naptha and also have you tried using glycerin and or acrylic paint? both help is dry faster and the glycerin helps the silicone from sticking. just a thought.

[@GEOsustainable]

Have you tried this?

[@YerroPhunder]

@@GEOsustainable yep just tried both glycerin and acrylic paint to make molds for my gundam model pieces. also i used xylene as the thinner since i found a post saying that xylene shrinks the least out of all the common hardware solvents. (xylene may still be hard to find in some places since only one store carried them in my city.)

[@YerroPhunder]

@@GEOsustainable im wondering what your experiences might have been when using naptha as the thinner in terms of shrinkage.

[@YerroPhunder]

had a bit of trouble with bubbles but my male side seems to be relatively passable as i expected to be filling holes anyways and am quite experienced with that. amd working on the female side as we speak! i am eager for your reply!! and thanks for the quick reply!!

[@GEOsustainable]

@@YerroPhunder There is shrinkage, and the more you thin it, the more it shrinks. IT wasn't much for the mold O made. But, you have to guage what is acceptable yourself.

I am trying to make a mold that is flat for a resin pour to make a lampshade. So,basically a slab , but in different shapes for each lampshade. Which mix would you recommend? I’m struggling with this. Thanks in advance!

[@theokrisna]

I wonder you can cast the thinned silicon caulk in the, let's just say plaster mold? Will it be ruined (because the silicon gonna be shrinking with this method right)?

[@GEOsustainable]

Try it. You never know until you try.

[@MigaMotors]

How long does it take this silicone to cure in the hydrogen peroxide? And how long if in air?

[@GEOsustainable]

In hydrogen peroxide, it skins on contact, preserving the tube,a few minutes to an hour for full cure. In air, the tube will close up.

[@aaquilina5221]

how can you make a safe material, to make barbie dolls? Not to make the mold Press itself, but the material to make the Doll? Thank You so much for your videos! Very Educational !

[@pawandev23]

Please let me know which would be the cheapest clear silicone to be used for the same? Do we need H2O2+ water in each and every case? What curing agent other than H202, be used for the same? I want to get transparent and flexible vascular phantom models.

[@GEOsustainable]

GREAT questions, again! Firstly, they will be translucent at most. If you need them to be transparent, I have a few videos on Casein you may find useful. You can use the cheapest clear silicone found at a hardware or home supply store. Yes, as shown in the video is how to use water and H2O2+. The curing process is explained during the demonstration. It should work very well for your project. Thank you for your questions.

I tried the bag method with an entire tube of silicone caulk, but the silicone was already starting to set within 5 minutes it kneading, making it impossible to pour. Am I doing something wrong?

[@GEOsustainable]

Yes, you used too much cornstarch. I use 10 grams of cornstarch to every 100 grams of silicone, which I mention in many of my videos. This will give you a set time of about one hour, plenty of time. I have a later video on this method, check here. kzbin.info/www/bejne/qXq0nHmMm9l3kLc

I really wish you'd have a clock on the wall or make the excessive effort to indicate cure times, I've watched many of your videos and greatly appreciate the content, but I feel like everyone I've watched I'm usually sitting at the end going.. how long?

[@GEOsustainable]

I will make sure I make a banner to indicate the time, but I usually do say it. Stay tuned, I am making a new video using all the great comments I have gotten. Thank you for telling me where I miss. This method takes about one hour to cure.

[@scallywagon9395]

I think it's fair to say there are other (at least 1) videos on this topic, nearly identical. Almost copied. It would be nice if the original video provider were tagged, but I don't think that happened. If I copied someone's video I would certainly tag the original video I stole the idea from.

[@GEOsustainable]

I think I would need to tag thousands of videos, but I get where you are coming from. It is a popular subject for videos. Thank you for pointing out, others have done this before me. But I got this from my high school shop teacher, and felt it was OK to show folks how he did it.
