Hollow Cast A Complex Part - The Mother, Cradle And Cutting The Mold, Part 4

How to make a silicone lay-up style mold. This video is continued from part 3. I show you how to make the resin mother mold, the cradle for the Rotator and cut the silicone blanket mold open to make a brush-on silicone rubber rotational casting mold.
----------------
Would you like to mold and cast something but have no idea how to start? Send pics of your project to me and maybe I’ll do it as a KZbin video.

thanks a lot :)

[@rich_3d]

If I could like this video twice, I would. Thank you.

[@ruthang9065]

You are a true master! Thank you for sharing your knowledge and time with us. A hug from Italy!

[@sethalump]

This is amazing. I have zero need to mold anything but I can't stop watching. Thank you so much for sharing your craft!

[@robblatt9120]

The joy you have when somethings works is infectious!

[@RobertTolone]

I never get tired of it!

[@t4concepts]

You're the reason why I haven't been getting much sleep lately! Up till the wee hours of the morning watching all your videos ; ) I've been making silicon and resin moulds for a couple of years now, but it's always interesting to see new techniques ............. and I may even change to way I've been doing them! Many thanks Robert Now subscribed! ; ) TURK - France

[@RobertTolone]

Thanks for watching my videos! Another viewer wrote to me and said I should bill my channel as an ASMR channel because he found it so easy to fall asleep listening to my videos! 😳😀

[@t4concepts]

@@RobertTolone How uncouth of him! ................ I guess he's not very interested in mould making then! Your videos ( and your approach to the subject ) are what keeps me awake! ; ) It's 4:30AM here in Central France right now ........................... and I'm still finding fascinating videos to watch.

[@ArcticFlies56]

Bob, you have out done yourself, amazing amount of work and money in this mold. Job well done!

[@RobertTolone]

Thanks Richard!

[@roger.agburn]

That mold was a lot of work, as the videos have shown. Wow, didn't expect that from the beginning of the project. ^_^ When you know how it was designed, and how it is gonna be used, you really can see the beauty of this mold. I liked that rubber surrounding for the cutting line the most.

[@RobertTolone]

This method yield very nice castings. But it is a lot of work to build this style of mold!

[@Creat1ve_Me]

You are a huge inspiration. I have only started sculpting and recently tried mould making in the past couple of months. Having access to your skill and knowledge is mind blowing to me. Thank you Sir for sharing.

[@RobertTolone]

Thanks for watching. I appreciate it!

[@kristacohen8210]

Is there a time when you'd find it necessary to bolt together the mother mold instead? I really like the idea of holding the whole thing together with rubber bands. Less stress on the mother compared to bolts, and less chance of compressing hard enough to deform the mold. As always, thank you for your wonderful videos and insights.

[@chrisdonohoe3314]

Great videos Robert, far more detailed than anything else about mold making on youtube. and you make it great fun to watch! keep up the good work! :)

[@RobertTolone]

Thanks Chris!

[@davesilva9174]

Amazing. Educational.Inspiring!

[@RobertTolone]

Thanks Dave! Looking good so far. This mold will rotocast resin well. It should also work for hollow casting Hydrocal and that could be done using the hand slush casting method.

[@naldomination]

Amazing techniques! Thank you Robert!

[@RobertTolone]

Thanks for watching!

[@theantichrist6524]

Really good job

[@RobertTolone]

Thanks!

[@amilcarmiguel7274]

Belo tutorial, obrigado por compartilhar !! 🇧🇷Londrina, Brasil

[@RobertTolone]

De nada!

[@sonicUnison]

Now I know why you have cleats for rubber bands to keep the mould closed!!

[@marklivett1504]

Great tutorial, learning lots! Quick question, could you use plaster bandage to make the mother? Do you just prefer resins or are their physical properties which make plaster unsuitable? Thanks

[@RobertTolone]

Yes, you can use plaster bandage to make the mother. I use what I have on hand. The trowel-on resin that I used in this video was designed as a coating for foam sculptures. But it’s also great for brushing on inside of molds and making mothers.

[@carolsakai-artist]

@@RobertTolone I appreciate your answer. .. on your more recent video "Molding A Glass Lamp Shade - Part 1". . . you use a fiberglass mother mold. What are the pros and cons of using various materials, I know that reinforced plaster is heavy. .. I am concerned about the toxicity of the fiberglass catalyst since I have solvent sensitivity

[@RobertTolone]

@@carolsakai-artist Any material that works well for you is the right one to use. Plaster bandage shells work fine and have the advantage of being quick and relatively inexpensive to make. Their main disadvantage is the weight.

[@carolsakai-artist]

@@RobertTolone thanks! I'm learning so much from you

Thank you ☺️❤️💞 new subscriber

I appreciate your support very much!

[@taelorrhodes8356]

I’m just here to thank you for sharing your knowledge with all of us :) this is an intimidating skill to learn, but your videos are so encouraging and thorough! If I’m looking to mass produce, is outsourcing often more cost effective than casting?

[@RobertTolone]

Depends on how many units you are planning to make. Generally speaking outsourcing is cheaper but also has it’s own set of problems: quality control, customs, etc.

[@liamcunningham2285]

great series! I learned so much! I like your refrigerator, has he been working out?

[@RobertTolone]

Refrigerator never works out, he is just naturally buff. I hate him for that.

[@treblam1]

Came out great! I have a question. What is your argument on two part clay molds? I know you prefer to use the zig zag method of cutting open a mold. (which is good also) How would you do a two part clay mold if you had to?

[@RobertTolone]

Occasionally it is necessary to clay up a model to make a mold. I do it when I have to. The arguments against clay-up are these: Applying the clay is finicky and time consuming. The process may harm a delicate model before the rubber is applied and the damage to the model can be transferred to the castings. The parting line will always be visible in the castings and it will surround the entire model. So it takes much more work to clean up the castings. It is a multi-step process involving at least two rubber pours. So it takes much longer to complete the mold. That said, a viewer sent in a project that requires a clay-up mold and I will be doing that soon. I am not opposed to clay-up molds but a cut-style mold will always be superior to a clay-up mold when either method can be used on a project.

[@treblam1]

@@RobertTolone I see that your Kung Fu is Great!!

Hello Robert. By the way, I liked this serie a lot. I have one question: what is the material for making the outer shell called? I would like to know the exact same thing you are using here because of its consistency and drying time. Thanks in advance!

[@RobertTolone]

Hi Gerardo, that is a urethane resin called Trowel-On 60. It is sold by www.silpak.com. If you contact them please let them know you heard about them from my KZbin channel. Thanks for watching!

[@dianeharris2687]

My burning question throughout this whole process has been... But why? Why make copies of this unfortunate pug cup? But I've enjoyed watching the whole deal. Thanks for doing this.

[@vsmash2]

because the shape is challengeing

[@RobertTolone]

There is no rational response to the question why. Why? Why not? Why? Because. I think the Pug owner wants to use it as a cup holder at festivals and parties. Maybe as an attention getter or maybe just for a laugh. I rarely care about the thing. My fun is in making the thing.

[@wulliemarshall4976]

Robert enjoyed the video and have learned a few things from it, however I would be grateful if you would tell us what the slush resin is called as it would help.

[@RobertTolone]

It is a two-part urethane resin called Silplastic sold by www.silpak.com. They are my material supplier, not a sponsor of my videos.

[@BobbySandoval-v7q]

hello Robert I need help with a small yet complicated part. well at least for me its complex thank you!

[@levinebette15]

How heavy is that mold?

[@davesilva9174]

Appx.3-4 lbs

[@roselolagne6642]

I have a project I need help with!!!!! ive tried myself and epically failed. My goal is to make a silicone teether that goes on your finger.
