btw, Ive heard you can use talcum powder as a parting agent, is that true? Does any powder work?

[@RobertTolone]

@@Aconspiracyofravens1 It depends on the materials you are trying to keep apart. It is always best to test small samples to see what works with the materials you are using.

[@Aconspiracyofravens1]

This is some hardcore mold casting. I was listening to a spotify playlist containing the epic movie score "Once Upon a Time in the West" composed by Ennio Morricone, from the 1968 western film of the same name, while you were taking apart the second part of the cast. And when I saw how the mold came out... Forget about it! Epic moment :) Great content!

I'm Astonished about what you did there, A really nice job! I'm actually trying to figure out how to mold a piece from my car that is reducing into bits due to it's old age and buying a new one is costly and wouldn't be resist enough if it's the same material. But with your video I might found the solution on how to proceed and that could be really awesome. Cheers

[@peterloring7361]

Robert, I was at a production prototype shop years ago and they used the cut mold method as well. A couple of different methods they used could be interesting to you. 1. They used clear silicone so that they could see the pattern as they cut it out. 2. They used much thicker boarder walls to support the mold haves. This allowed them to use packing tape to join the molds before the pour. Some of their molds were the size of a small refrigerator. 3. To locate a perfect parting line on flat faces: They used 3M Scotch tape. They'd place the tape on the flat edge and have a good 1/4 inch flare sticking out into the cut area. They'd mark the tape flare with a black Sharpie so it could be seen in the clear silicone. The silicone doesn't stick to the tape so at that point you will get a flash, but you'll have a perfectly placed parting line. This trick does change the shape of the pattern by the thickness of the tape, which is about .0015 inches, so it is not a concern to most customers.

[@RobertTolone]

Pretty interesting, thanks!

[@GeoGamerArtistVlogger]

How absolutely fascinating!!!! I had no idea there was such a long and complex process to make a 2 piece mold!! I thought I could just make a whole complete mold, cut it in half, and it would work (spoiler alert: it didn't. I'm still trying to scrape hardened clay out of my microwave oven. This is what I get for trying to make a silicone rubber mold with no experience, all because autism demands equality in things I make and I would probably lose my mind trying to sculpt 4 paws by hand and get them all looking the same, haha. The clay leaked because the silicone mold deformed from the rubber bands and I didn't noticed until too late)

I do have a project I'm curious on what your approach would be, but I'll think about sending that into you some other time.

Is what it is for a video 3 years ago. I look forward to watching the rest of your videos. I also look forward to learning some of your subtle mold making lingo and verbiage.

This video and others I saw yesterday have been valuable. I'm going to try my hand at casting a scenery piece with silicone rubber. I had imagined most of the process combined with some videos I'd seen years ago. But this was awesome. I appreciate your design on the autoclaves, I have an old dentistry autoclave which I will be using both for pressure and vacume, but I will have a max of 4 bar pressure due to the door seal design. Your oval shaped doors with internal plates is an amazing and easy way to negate that problem. I fact everything I've seen you do seems to be the easiest way imaginable, no doubt learned from years of experience. Thanks for the great videos.

[@PolterabendForNC]

Oh man Robert, you are literally molding my mind with your priceless knowledge. Fantastic execution in video in combination with your playful attitude.

As the stripped down body heads off to my Friend Bill Kandy for sand blasting and epoxy primer, I am looking to replace all the rubber on the car. Miraculously every single thing is available for this car EXCEPT ONE! The Vent window seals.... you know!, those little triangle windows in the front of the door that blow fresh air on your face? They are complex and are even "bonded" to a thin piece of sheet metal using what is obviously planned flashing. I am going to root around here and figure out how to send you one to give a look.
