A million points for packing tape and cardboard. I've used corrugated cardboard covered with packing tape, held together with hot glue, for years to make mold forms. I started using packing tape around 2013. Before that I used glossy cardboard because platinum cure silicone wouldn't stick to it. At some point I couldn't find glossy finished cardboard to make a form and the thought hit me that I could use packing tape. I've extolled the cheapness and versatility of packing tape, cardboard and hot glue to many people doing silicone molds and most of them continue to use things like LEGO, or L boards and clamps (I made a few sets of L boards before I started using cardboard and pressure casting the molds.) or other items that are cumbersome and give poor results. Apparently they think it just can be that simple and easy. I've been in this as a business since the late 1990's. Followed a lot of advice early on that gave poor results but over time I came up with techniques that are easy, low cost, and make good molds and castings. I mostly make reproduction parts for classic cars, including pieces that have gone onto cars shown at Hershey and other concours d'elegance shows. It all started with a need for a pair of tail light lenses for a 1953 Hudson Super Wasp... I had one good but faded lens, made a latex mold supported with fiberglass and cast new lenses with clear polyester casting resin and a ton of transparent red dye. The results were terrible but with a lot of sanding and polishing they worked. I'd grown up in a ceramics business where I learned about mold making concepts, which applied to fiberglass (I made some parts for a Mustang, still have the molds, people want the parts but don't want to pay enough to cover the materials cost) and also to silicone. Thankfully with silicone undercuts and other things not possible with plaster or fiberglass can be done.

As someone with minimal experience making molds it's actually very helpful to see you without your tools. Just to see how you work and think.

Just got into this channel (40k models trying to reproduce), and I was just saying to a freind: "This guy makes it look fun and easy, I think I could do it. But I don't have a vacuum chamber..." 2 hours later, I see this video.

I love the grumpiness that comes with age :) "Damb kids nowadays, with their hot glue skills! ...in my day...." :P I'm at that age too :P

So it really all comes down to brushing on a print coat in order to avoid bubbles. Good to know. That's exactly what I was preparing to do with my upcoming, really important, must-not-have-bubbles, project.

Grumpy old man Robert. I feel ya

Wow really reallt smart way of doing things! As always yiur explanations are excellent! I learned so much and you are very resourceful. Please always stay healthy too. Keep it up!

There's a trick for pouring from a wide-mouthed container into something much smaller: 1) Get a rod that is longer than the container is wide (I like something about 2-3 times as long). For that container, I'd be thinking about either a piece of wire coat-hanger or a chopstick. 2) Lay the rod across the top of the container with most of the excess on the side you will be pouring from. 3) Pour. When pouring, the surface tension of the liquid will tend to adhere the stream to the surface of the rod, so the liquid will follow the rod. This can take a bit of practice, as too much or too little flow can both cause problems. 4) When you have enough out, leave the end of the rod in/over the receptacle while tilting the wide-mouthed contain back to stop the flow. 5) Allow whatever is still on the rod to flow into the smaller container, then clean the stick. I've used this for pouring paint into 15ml/0.5 oz plastic squeeze bottles without really any problems; it should work fine for resin or rubber components as well.

Love to see the way you work and your patience, your videos are both relaxing and informative

I made myself a few mixing paddles that mix well without drawing bubbles into the mix. They are small brass sheet squares soldered onto a hacksaw slotted round copper rod. The paddle is small enough to always stay submerged in the mix while the round shaft is all that breaks the surface and it reduces the bubbles. I find a gentle scrap of the sides is all that is needed to ensure a full mix.

Thanks for this video! The blowing out the bubbles technique looks valuable and simple. This was full of really wise words/techniques for anyone who was listening.

Great video, Robert. Really enjoyed it. Cure inhibition and bubbles have been my greatest enemies. A number of steps taken and 7-8 molds later and I've got it dialed without a proper vacuum chamber (I did actually build a homemade vacuum chamber with a shop vac and few other household items, but its not 100% percent effective. Would need stronger vacuum and stronger walls). Thanks for your help !

Hi Chris, the first vacuum chamber I ever built used a shop vac and it was a miserable failure! In this video I explain why shop vacs don’t work: kzread.info/dash/bejne/g4lsrLVueL2vido.html Platinum rubbers are much more sensitive to cure inhibition than tin rubbers are. Sulfur and metals such as copper and brass are notorious for causing cure inhibition. But you never know when some bad chemical reaction will rear its ugly head. That’s why you must always test your materials to see if they are compatible.

Lol this is how all my molds go! Even my bigger pieces!

Hi Robert , Thanks again. Its very pleasant to have your vids on while working. Right now as i watch your mold techniques and colorful comments ..hiih.. im trying to make some custom scifi looking lights for a head piece..could find what i wanted but had some latex rubber to make dip molds. ithas that nice brownbeige rubber ..and is pretty strong stuff... made a flat mold of corrugated material ( gonna fold over with LEDs in it to form corrugated tubing thats semi transparent with mesh sealed inside ..the layers uneven mostly from the latex layering..will give that faded..yellowish ..scifi..relic almost burnt out look.... but as you might be able to guess..its 20 sec application of a new layer ..and 20 min / hour dry time.. so your vids are running on my comp screen next to me... and its really nice. I guess its a man thing ,... seeing someone working ..busy...kind of makes you wanna do something too .. and really helps with the "..i dont really have to.."..that sneaks in after being stuck inside for almost a year now.... So yeah... My new happy place online...been learning more that i thought i would. Thats gonna come in real handy real soon i'd bet.

Oddly, tin-based silicone rubbers are condensation cure rubber, meaning that they actually pull moisture out of the air while curing. I have heard that extremely dry environments can inhibit the cure or at least slow it down. But then I have never heard anyone recommend adding water to the rubber to speed up the cure. But my blowing on the rubber certainly did not negatively affect the cure of this particular mold.

People do it all the time but generally use an airbrush .

Using Rubbing Alcohol will soften up the hot melt glue and it comes right off. Awesome use of scraps in the mold.

I used Magic Mold a few times and I found that making the mold box out of waxed cartons makes it a breeze. I clean out the waxed carton of Half & Half or Orange Juice and cut them up and glue them back together as per my needs and they work great. Once in awhile I may even use a little Vaseline to coat the carton for extra insurance. Coated Card Board never worked for me. I even used spray release on some. They always came out good. The Exacto Blade Knife is the way to go for cutting the mold apart. Utility knives are way to wide and bulky. I enjoy your videos and I’m learning a lot as well. Thank you. Richard

Hot glue is easy to remove if you use the cheapest one you can get. Because that is not as flexible as good hot glue and is thus easy to peel off.

I'm curious: can you use the bubble-popping technique with an air compressor tool (instead of the straw) when pouring bigger molds?

Gave this a quick watch yesterday night, and will probably re-watch tonight to try and make decent/good candy molds for an upcoming thing. While I think I understand everything else, was there a reason you poured the silicone in several smaller batches/layers(not counting the paint on and the feet part) or was that mainly due to the various cardboard angles, chunkies, and other elements that helped save on the silicone?

Great vid as usual. Do you know if there is a liquid that you can add to the basic silicone to make it a bit more runny?

I have never found or used such a product. Although there are products to make the silicone thicker. You can shop for low viscosity silicone rubber and refer to the material data sheet as to what the viscosity is. The higher the number, the thicker it is. The material I usually use has a viscosity (cPs) of 50,000. There are manufacturers that sell low viscosity silicones they claim do not require degassing and have a viscosity of 7500 to 10,000.

I don’t know. The only way to find out is to test it. I always test unknown material combinations before pour a mold. That way I know I won’t get cure inhibition. Mix a small amount of your rubber and put a dot of it somewhere inconspicuous on your candle. If it cures you’re good to go. If it doesn’t you’re not.

Would you recommend that I coat the subject in a release agent first before brushing on a print coat, and if so, what kind of release agent would you recommend for best results?
