A thought on the PVC tube removal. It might help removal to pin a vent filament to the PVC, running down the side, which could be removed first to let you break the air seal around the tube and give you some literal wiggle room. Maybe a bee's wax candle wick would be a better option than just a wax rod so you can tug it out easily. Anyway, amazing project. I've really enjoyed your channel and appreciate you sharing your craft with the world. Thank you!

I hate the word expert and professional… as from my experience it’s a means to make money from something you don’t know or don’t own… rather than someone that truly understands the field and is always willing to learn and show others….. no secrets here just a very hard working knowledgable man…I’d pay good money to have moulds made from you… but hope to make mistakes making my own.

[@flickpad]

If it's important to let the lower layers of resin gel to prevent the weight of the resin from pushing the mold apart, then will Sarah's mahoosive pressure pot still work? Will it be able to collapse bubbles in resin that has already gelled? I've absolutely loved watching this project. Anyone can see that it's a real challenge. I think Sarah chose the right guy to help her!

[@RobertTolone]

No, you would have to pressure each successive pour individually.

Amazing work. I really enjoy watching you work, and teach. Every one of these cut-molds you do, I am always amazed how resilient the mold material is and at how strong as well. WRT the resin, do you experience any visual flaws between subsequent pours or do the different pours become homogeneous? [edit] - oops, asked and answered if I watch the whole video ...

[@kaioken654]

Are you good at chess? Because you're always thinking ahead in these projects, this one blows my mind

[@srpracingdevelopments3728]

Hi Robert. Could you please advise, or maybe do a specific video on colouring urethane for casting. Im very interested to understand the impact of dye concentrations and what is possible in regards to colouring. I need to know how to achieve a solid white finish for a project. Thanks for your effort.

[@RobertTolone]

Some time ago I did a video on coloring resins: kzbin.info/www/bejne/iIW6m5huhLV8fKM. Start with a white resin. For instance, my regular supplier Silpak sells the Silcast 2 resin which I used to cast the sculpture in this video. You could also add a pigment such as the CU White pigment they also sell. Follow the manufacturers instructions for the correct pigment/resin ratio. That would result in nice white castings but be aware that urethane resins change color as they age, typically becoming darker and more yellow. So I always recommend painting castings to ensure they will maintain the desired color surface.

[@srpracingdevelopments3728]

Robert Tolone thanks for the response. You are a clear inspiration. Love your efforts

[@LinauLee]

Sweet!

[@chartle1]

If anyone remembers the tv show Face Off they used to use water based clay and were not recycling the clay so they would take it out side and use a power washer. It was always a rush since it was reality tv they built tension by putting on a time limit and if they didn't finish couldn't get their pieces done in time by the overnight molding crew.

[@RobertTolone]

Never saw that show.

[@LaurieSullivanRoy]

Wouldn’t using a less viscous silicone be easier ? Or no ?

[@tylerttinsley]

I’m wondering if you could get some cheap airbrush needles to probe the thicker sections and find the model inside the rubber.

[@RobertTolone]

You could and poking the rubber would not hurt the mold any.

[@peircedan]

surprised to see the flange come off. I have seen others reuse a mother mould after the rubber wears out.

[@RobertTolone]

I don't expect this to be a long production run. The mold is so smooth you could extend a life quite a bit with mold release

[@dewexdewex]

Wouldn't using transparent silicone rubber be better for cut blanket moulds for complex parts like this one? That way you could see where to cut to and get better part line positions around awkward features.

[@RobertTolone]

Yes, it could definitely help.

[@h7opolo]

7:29 i guess you forgot to put mold release on the pvc.

[@RobertTolone]

They were waxed but release sure would have helped.

[@glenfisher728]

Great effort there Bob , I don't think some people realise how physical it can be separating silicone or shells . With all that heat how much linear shrinkage did you get on the casting ? Good to see digital scales. 😉

[@RobertTolone]

So much that I made a separate video on it. It's coming up.

[@consumer365]

Robert is the Bob Ross of reproductions.

[@robblatt9120]

Really interesting to think about the heat generated with a piece that size. Does that heat cause any expansion among the resin, possibly causing that misalignment or is something that you hope would push upward instead of outward?

[@RobertTolone]

Weirdly, the resin actually shrinks as it cures.

[@75keg75]

Is it worth having a drilled hole in the pipes end so that you can put a hook or bolt through it to aid in extricating the pipe from mould?

[@RobertTolone]

Yeah that might have helped.

[@runin1wild149]

By George I think you did it! Marvelous! That had to a pretty costly project right there! This was definitely fun to watch. I hope we get to see you finish the slip shade project, the anticipation is killing me! 😂 I’m just curious to know what the weight of your casting and the original difference is?

[@RobertTolone]

The original was painted wood so it is less dense than the casting.

Very positive. But my community is a joy. Everyone is enthusiastic and nice!

[@chartle1]

21:00 assuming trimming that little flap would just make it worse.

[@RobertTolone]

The flap caused no problem at all and that area cast well. Had I trimmed that flap off that would have been a substantial chunk of resin to sand off on every casting. And in a very inconvenient location.

[@ramanaxp]

Sir , I which type of resin is cheap and best for metal casting . Please guide me . I am doing practice after seeing your videos . You are highly professional. I am taking you as my master.

@@RobertTolone sir . I am fancy jewellery manufacturer . for purpose dye I am using silicon lubber . for moulding using wax . but wax is missing details and breaking small parts. instead of wax can I use resin ?.

[@sgajate]

Awesome video as always!! Quick question, could you do a rotocasting of that mold? (I'm thinking that maybe in that case one could've used a lot less resin and not have the "pouring layer lines") Thanks for the great work!! All the best from Argentina!!

[@RobertTolone]

Not the best shape for a rotomold because of the arms and legs. It would be very difficult to get even wall thickness in the casting.

[@sgajate]

@@RobertTolone I see, thanks for the answer! And thanks for all that you teach through your videos! Cheers from Argentina!

[@aaronhelmsman]

I have no doubt that your molds are airtight. Have you thought of using compressed air to push apart these bigger molds?

[@RobertTolone]

That would only work until a tiny gap opens up somewhere in the mold. Then all the air would simply escape out of it.

[@marionschneider8020]

Thank you so much Robert for this amazing video ! Helps me a lot in planning a future project. I'm curious, how long did the total process took you ?

[@RobertTolone]

I did not keep track of the hours and the project was spread over about a month because it was done alongside other video projects. The longest and most tedious part was the clay work. Also I was working in a small temporary shop and did not have the advantage of all of my tools in my home shop. Probably 40 hours of work, not counting time waiting for rubber and resin to cure, etc.

[@marionschneider8020]

Not a small project indeed.. Thanks for your reply and all the effort put in the video !

[@brianlindsay9097]

Wow, super hard-core project. Very impressive! I have an unrelated question: Do pressure pots distort molds? I have a can-sized single cut mold, secured with rubber bands, using a soft silicone (Shore 15A). I poured epoxy into it once, and it looked fine (except for the bubbles); and then again later using a pressure pot, and the cast was taller and thinner. Is there a good solution for this? Thanks!

[@RobertTolone]

Hard to say without seeing it, but it sounds like the pressure pot is distorting the mold. Did you degas the rubber before pouring the mold?

[@brianlindsay9097]

@@RobertTolone I did, but I did not cure the mold under pressure as I've been told to do (this is kind of a test run). The odd thing is, if it is the pressure, I would expect it to bloat rather than stretch...

[@davyspark3435]

I think you might have made a mistake when removing the pvc pipes. I think removing them after you have removed the bolts could have caused the mold halves to shift slightly, causing the pipes to jam. It might have been better to remove the bolts after removing the nuts and bolts.

[@chartle1]

did you wax the tubes this time?

[@RobertTolone]

Only waxed them once.

[@EV4UTube]

QUESTION: You showed where you made "exploration cuts." In most cases, you mentioned that those cuts were not going to be detrimental to the casting. However, there was one cut that you were not crazy about. You pointed out that the cut created a weakly-supported "peninsula" of rubber. My question is two fold: (1) Let's say that you just didn't like those exploration cuts (or maybe they were causing flashing problems), could you come back later and just "glue" the cut pieces back together with a little bit fresh / soft / pre-cured rubber? (2) For the one cut that you were not crazy about, could you "glue" it back together with fresh rubber and then, after full curing, come back to make a more definitive or confident cut that would provide better support?

[@RobertTolone]

In this case the mold worked well even in that problem area. Because you're working blind here's no way to make a clean repair gluing the mold. Better to leave it alone.
