You made no bones about moulding and casting this project (as always). Very good and useful techniques for solving something that looks deceptively simple. The combination of the objects put a new spin on the task. Thanks again Robert.
You are one of the best people on the internet and I am forever grateful for the wisdom you impart. Great video (as always), I've been recommending you here, there and everywhere!
"Again, this is a very, very, very, VERY soft and flexible part, so I'm being very careful not to hurt it." *2 seconds later* "BWEEP!" *flops it around while laughing*
Hi Robert, I just found this youtube channel. Thank you so much for taking the time to explain your processes and projects step by step. I learned more about mold making from your channel than from my first year in art college, where I was required to take a sculpture course with a teacher who asked us to "feel the tilt of the Earth" as a lesson. (Art school is weird, I love the internet.) This video helped me learn how to cast my wisdom teeth correctly! You are truly a master.
I want to thank you for these videos, the exceptional quality of not only the videos themselves but also your explanations have inspired me to start resin casting myself and have played a major part in helping me overcome the slump ive fallen into after finishing uni
Oh man I know that feeling of putting in all of that time and effort just to have the final step make or break the project! I used to work for a metal and enamel pin company. I was in charge of the delicate painting process of thousands of pins done completely by hand which was usually the final step before packing and shipping. I had MANY nerve racking moments where I would have to just dive in head first and hope for the best haha. Most times it worked out luckily but not without worry and careful consideration/preparation. I also became a master at mixing any pantone color in existence from about 20 different spray paints. It was quite the experience. Unfortunately I developed a repetitive strain injury rather quickly and it's never fully healed. Makes my craft a bit harder these days but, I really appreciate your craftsmanship! Another great video.
Once again brilliant proof of your talent. Liked every moment of it and will try out the cardboard easle soon. Great show. Allways hopeing for more. Thank you master!
I didn’t look so brilliant when I glued the thing together upside down! Fortunately I realized it in the nick of time and tore it apart before the epoxy set!
Last Halloween I made finger bones as part of my costume(scooby doo witchdoctor villain). Anyway, I made two originals out of apoxyscuplt. Then made a lego mold box and poured the silicone. The design didn't require any cut to the mold as they would pop out once set. I cast 3 sets for a total of 9 bones. It worked great and several people thought I used real bones.
Wow..I wish I had access to the equipment and the skills to make all these molds. I have the desire and passion. Guess I will do whatever I can with what I have available to me. You inspire me to think out of the box.
Thanks for watching Ann. It took me a long time to build my shop and my skills. I am hopeful that my channel can save peoples time by sharing what I have learned over the years.
Informative and entertaining as always. You mentioned casting more complex thin shapes flat and then bending them while the resin is still soft. If you haven't done such a video yet I'd love to see one (I know this video is a year old, I'm kind of working my way through your backlog randomly). That said, I do wonder if heat would be a problem for such a process. What I mean is, many miniatures I get for board games arrive bent, but generally a minute or two in hot water will cause them return to their proper shape. Would a particularly hot day have a risk of causing a mold that was cast flat, and shaped while soft, to return to it's original flat shape?
The amount of heat required to bend resin that cured in a particular shape would cause any resin casting to potentially warp or bend. I’ve never had a problem with castings that I used the bend-while-curing method on.
Amazing skills! Just a joy to watch you sir! Is it just me or does any one else find his voice and personality remind you of Sparky? Christmas is almost here....!
Great video. I did have a question. I am starting a mass project of casting around 100 duck and geese skulls for an art installation and I was planning on doing a multi part mold. I didnt know if a cut mold would work will very thin parts and a few decent undercuts. Would love to hear what you think. Thanks for making great videos!
Lol maybe you should invest in a silicone rubber spatula , it was pretty dam close! I love your personality/humor and how you take pride in your work! This differently was a good video! Leaned a lot!
The trouble with silicone spatulas is that silicone rubber sticks to them. I use stir sticks because I have lots of scrap wood in my shop so they are cheap and available. Downsides are that they don’t scrape the containers as well as a spatula and they might possibly get debris or moisture in the rubber. Glad you liked the video. Thanks for all the comments!
I'm new to your channel so you might have mentioned this in a previous video but would you recommend tapping downs mold to get bubbles out from the top like that or is that a bad idea? I know I saw you mention when filling a mold with resin you can tilt the mold sideways periodically to avoid big bubbles but wasn't sure if that's another method that can be used in this situation.
Lovely video, Robert. I wonder why small portions of resin harden slower than big pieces. I would have expected vice versa. Do you know why it is like that?
I I’m not enough of a chemist to tell you. It may be because larger masses generate heat and heat definitely speeds up the reaction. It may be because there are fewer molecules to cross link. If anyone out there is an organic chemist, help us out!
@@RobertTolone Yes! I was thinking of a oviraptoridae or dromaeosauridae. I think it would be a foot in total length and 5" tall and a max diameter of 5"
Thank you for these videos, I appreciate your expertise! You said that to remove thin objects such as these, you either needed to be very careful in the removal from the mold, or wait a much longer time for them to fully harden. If you had chosen to wait, could you guess what sort of time period would allow these bones to fully stiffen?
I neglected to mention another option, that would be to heat the mold to around 100°F. That would definitely accelerate the cure. For these wishbones I think you could probably extract them from the mold after about an hour at room temperature and they would be mostly rigid.
Isn't it amazing how good the cheap Ace Hardware house brand paint is? I use their primer alot, and they have a nice semi gloss black that makes a good finish for auto chassis parts.
It might work although if you have to distort the mold a lot to get the bird out it may wind up damaging the casting of the wishbone. But you could give something like that a try. Usually I cast all or some of the cavities in each mold and remove them with each cycle.
Awesome! Also, thanks for compressing into one episode! Question: Is it better to make the shell(cardboard, resin, etc.) First, for the silicone mold then cut the parting lines in the silicone mold OR cut the mold first and then create a shell to hold the mold?
How well does 'wet' blue silicone mold stick to dried blue silicone mold? In other words, if you discovered an error once the mold was dry could you 'patch' it?
The silicone sticks well to itself. That is why it is possible to build a mold in many layers over several days. I often incorporate chunks of old molds into new molds and have never experienced bonding problems as long as the old rubber is clean. That said, I find it very difficult to repair surface defects in silicone molds. For instance, trying to fill bubbles in the mold. It’s extremely difficult to get the repair to be invisible.
I would have preferred to cast them in 24 karat gold and polish them. That way I could charge thousands of dollars! But I am not a jeweler, I am a humble and lowly resin caster. 😄

😀😀😀
My favorite part of these videos is the suspense of "will it be just enough?" while pouring the silicone.
You made no bones about moulding and casting this project (as always). Very good and useful techniques for solving something that looks deceptively simple. The combination of the objects put a new spin on the task. Thanks again Robert.
why cant the other channels explain things this well? i wish you and you tube were around when i first started casting/moulding items! great video!
Im already in love with your charming sence of humour and the way you teach! Subscribed for sure!
Thanks so much for watching and for your nice comment!
Erm... I'm stunned. That is absolutely fascinating. Thanks for yet another masterclass.
Thanks for watching!

Robert, it is a pleasure to watch an expert work his craft. Thank-you.
Thanks Rick.
The technique of cutting with the jagged edge to the outside is wonderful. I've never done a cut mold before, now I want to try it.
It would be amazing to see how you cast complex forms like you said.Every one of your videos its amazing . Thanks teacher for another amazing class
Thanks Adriana!
Fantastic! I never would have thought about casting a wishbone, but it turned out amazing.
That’s why I love projects sent in by viewers. I get to do projects I never would’ve thought of myself.
Thank you, Robert. Amazed that you could get such a thin piece to come out just like she wanted.
Yeah, it worked out pretty good!
Luv this guy! He really knows what he’s doing! So many great tips!
Thanks for the nice comment Sharon!

@@RobertTolone I could say the same thing!

When you say rubber is expensive can you put it into perspective or does one apply for a second mortgage immediately?
You’ll feel the pain when you get the bill for your mold Paul. Part one of your video is next Friday!
Copper or Tawny brown under gold! Gold has three basic colors and you want to start with the darkest.
That paint is very opaque so I didn’t think too hard about the resin color. Good idea to experiment to see if It makes a difference.
According to The Eastern Orthodox tradition, the best body tone for layering under gold is a terra cotta red.
as always a great video thanks for sharing and the question I have is how long you had to wait for the casted parts after demolding to become hard?
Lovely video, Robert. I wonder why small portions of resin harden slower than big pieces. I would have expected vice versa. Do you know why it is like that?
I I’m not enough of a chemist to tell you. It may be because larger masses generate heat and heat definitely speeds up the reaction. It may be because there are fewer molecules to cross link. If anyone out there is an organic chemist, help us out!
@@RobertTolone The part with the heat sounds pretty plausible, thou.
Amazing! I want to do something similar for a dinosaur wishbone. Would you do this process similarly or differently for a larger scale model?
It would depend on the size as the process definitely changes with size. How big is your wishbone? I wish I had a theropod wishbone!
@@RobertTolone Yes! I was thinking of a oviraptoridae or dromaeosauridae. I think it would be a foot in total length and 5" tall and a max diameter of 5"
thanks again for the lesson

I've had issues like this before when casting copies of keys as an experiment. Keys tend to be really flat and thin, took a few days to fully harden.
Isn't it amazing how good the cheap Ace Hardware house brand paint is? I use their primer alot, and they have a nice semi gloss black that makes a good finish for auto chassis parts.
Yeah, I shop at my neighborhood Ace a lot to help them fend off the Big Box chains.
Is there any mileage in making 2 birds to 1 wishbone? Take out the first bird and cast another before taking out the wishbone?
It might work although if you have to distort the mold a lot to get the bird out it may wind up damaging the casting of the wishbone. But you could give something like that a try. Usually I cast all or some of the cavities in each mold and remove them with each cycle.
Awesome! Also, thanks for compressing into one episode!
Question: Is it better to make the shell(cardboard, resin, etc.) First, for the silicone mold then cut the parting lines in the silicone mold OR cut the mold first and then create a shell to hold the mold?
Always make the shell before you cut the mold.
😮. Pretty cool.
Could you make it cure faster by putting it in an oven?
How well does 'wet' blue silicone mold stick to dried blue silicone mold? In other words, if you discovered an error once the mold was dry could you 'patch' it?

@@RobertTolone Thanks for the response. Your work and vids are top notch. Cheers
Awesome thanks
Isnt it better to use black dye under gold paint?
I don’t know, it could very well be. That paint is very opaque so I’m not sure the base color would matter much.
you are amazing!
Thanks!
AMAZING!!
Thanks for watching Tiffany!
Thanks for sharing!
Thanks for watching Jina!
What is the iron tool for the wax you are using
Generally, he is using a Wax Carver, also called a Wax Pen or Wax Pencil. Specifically, he is using a Foredom K.WC-1 Wax Carver.
What is up with the bird? It has a handle but no feet. A tree ornament?
Yes, it’s a hanging ornament. I really only included it to demonstrate that you can gang multiple pieces into a single mold.
Do you also accept orders?😄
Often a warm brown is a good undercoat for gold, at least in miniature painting.
😎!
You’re home?
I was, briefly.
🌟
dingle-berries 😂😂😂
Bob, did you make a wish?
I forgot to.
You didn't make a wish ! (or did you?)
That's easy... now make a whole chicken appear from the mould.
Haha, it’s science Marc, not magic! What goes into the mold comes out of the mold.
I would have gold leafed them!
I would still be there!
I would have preferred to cast them in 24 karat gold and polish them. That way I could charge thousands of dollars! But I am not a jeweler, I am a humble and lowly resin caster. 😄
why not just sandwich some thin wire in the mould before pouring, it shouldnt obstruct the resin pour
