great tutorial Bill Doran! Funny enough, the picture on your screen saver at 2:29, is me in my Scorpion cosplay from last year! Was cool seeing it lol :)
hello bill, loving this series. can you do a more advanced casting videos. like how you do the castings with the foam inserts to save weight, and your ingenious way you came up with to cast the district 9 gun to keep weight down. thank you!
Do you have any tips for smoothing and finishing a clay figure that you want to make a mold of? How Intricate can a piece be for making a silicone mold? This series comes at a perfect time, Thank you so much for making these videos!
You have to make a light saber it would be so cool, I've always wanted to be a prop maker when I grow up, but just make a light saber it'll be cool. 👍😜
So are you recommending against making masters with deep crevices? I didn't quite understand that part. If you fill the crevice part way it won't make it into the mold as you were intending, so wouldn't it just be better to not have created deep crevices in the first place or am I missing something?
if you need to put those details in the final product then it will/could be easier* to make the holes shallow by filling them in on the master and then any copy you make from that will need to be cut deeper but your mold will last longer. once it tears that's a lot more cleanup to do with every copy you make from it or even have to make the mold all over again
To avoid this issue: When designing your master make sure deep crevices have an angled wall as opposed to straight walls. Reason being an angled wall means that the part will release completely from all sides evenly. with straight walls the sides will have friction as it slides across increasing the chances of a tear. In parts where this design method isn't possible you can always try for a higher durometer silicone (more rigid.) but still the chances are increased. Another thing you can do is create a pin or plug of some sort that can be removed after the part is out of the mold.
Great video Bill! i've been looking into building a mold and trying to cast some sort of resin, which smooth on product do you use for the casting part of proms such as a gun or a light saber?
I've noticed you use a couple different fillers like Bondo and a white type. Could you give more info on what fillers you use and why? Also any tips on mixing filler correctly?
Do you have to spray your master with a release spray before making the mold? Or does that depend on the material you make your master out of? Something I've been wondering about :P
@@txwing99 from my current experience it depends on your masters and the kind of silicone you use. I tend to not use it since it causes a sort of matte glaze on an otherwise shiny surface. That does mean my molds tend to have to retire earlier though :P
If a mold does rip or tear because of deep crevices as mentioned in the video can you repair them? Great videos, keep them coming, I'm loving this series and I'm also looking forward to answers to some of the other questions here. :D
Have you made masters with plastaline/oil based clay? Do you have any tips on prepping something like that? I was thinking I would need to make a one off mold + cast but I was wondering if there was something more cost effective....
Wrong video to ask this, I know, but I want to know what you guys think. I did some math and found that Quel'serrar from WoW is roughly 82" long given that the human male is 6' tall. does this sound right to you guys?
Hey Bill. Great stuff! I've been subscribed for a while but haven't really gone through much yet. I'm 100% a NOOB at making pretty much anything but have some pretty big aspirations! I thought I would start smallish and make a weapon before trying a full cosplay. I started looking at things for making a Sontaran rifle from Doctor Who a YEAR ago and being completely new I'm just paralyzed about how to even start! Have you made any video recommending how to get started from the very ground up? Thanks!
I suppose you already did the FAQ video, but may I ask a question? I have a fiberglass mask, and I want to make a silicone mask out of it, what material would you use to make the mold? thank you very much for everything, and I love the channel! Roniel from Argentina
Regarding crevices, what's the best way to sand and smooth the bottom of the crevice? Even jeweller's files don't fit well into the hole, and sandpaper/sponges seem too unwieldy to really smoothen out the internal flat part. Is there some kind of trick to it?
paint it black and hope its not noticeable. or dig it deeper than you need and refill with some of the same resin and let it set at the right level to give you a flat finish.
exaltdragon yeah, it takes a bit of practice though. most of the time it will be more of a smooth rounded finish. which can still look good. but can be hard to get the perfectly flat, square, like it's machined out of metal look. Someone really needs to make tiny flush trim router bits.
I'm hoping to make a silicone mold out of some small items, like dice, nuts and bolts, anything realy, to use ase a mold for like maybe chocolate or jello. I think it would be fun to make small snack like this. but I don't know if silicone molds are safe to use for food?
Just out of curiosity, can you master be painted already? I've got a prop that's already done and I was wondering if the I could still make a master out of that and if there would be any issues with the silcone adhering to it?
I've really enjoyed the series on mold making and I've had a very specific question about molds. I would like to do some white metal (pewter) accent pieces for props. Are you familiar with any silicone mold supplies that can handle the temperature of the liquid metal (450F)?
They did a video a couple weeks ago about that exact thing. They made a pewter amulet from Skyrim. All the details are in the video I'm sure. I'm super excited to try to make a few pewter castings myself!
Hi Bill! So I'm wanting to mold a Star Trek com badge prop that I ordered out of resin so make it a bit more screen accurate, but I don't want to screw up the original prop. Is that a good idea, or should I just live with the finish it already has?
Masters can be made from nearly any material. I like things like wood or sheet plastic like PVC foam or styrene. You could also sculpt it out of clay. The specific techniques depend on what you're specifically building. Here's an example: punishedprops.com/2012/05/08/mass-effect-m-6-carnifex/
As a total noob on mold making I like this series. Please keep it up :)
Thank you Mr Bill
great tutorial Bill Doran! Funny enough, the picture on your screen saver at 2:29, is me in my Scorpion cosplay from last year! Was cool seeing it lol :)
Thanks Bill, this is a great video. I'm loving this series.
im soon doing my first bigger mold, a daft punk thomas helmet with rebound 25 and plasti paste!
Never thought of the vinyl bit, awesome tips! :)
great video bill!
Can you make a video on how to make a master?
I would like to see this too. Just so we can see a good range of what materials are suitable for molding.
it would be sweet to get Frank on and talk about epoxy fiber glass molds sometime
+Bill Doran I know. I figured it would be helpful for everyone.
hello bill, loving this series. can you do a more advanced casting videos. like how you do the castings with the foam inserts to save weight, and your ingenious way you came up with to cast the district 9 gun to keep weight down. thank you!
maybe a casting 202 series? for more advanced stuff...
Love the video

This series comes at a perfect time, Thank you so much for making these videos!
Love this series! I really need to try to mold something
+Bill Doran Yes i need to buy the material and try to mold some of my model
It may be useful to show an number of though the above part with different finish treatments to show how the textures would end up.
What material does he use for the master
Hey Mr Bill i was wonder how you make your swords out foam yes making the edge is simple but what goes in the middle
You have to make a light saber it would be so cool, I've always wanted to be a prop maker when I grow up, but just make a light saber it'll be cool. 👍😜
I need to make a mold of an octopus with curly tentacles and such. I need your help figuring out the best way to mold this complex piece.
Very informative, thanks.
Hey Bill ,do you have a video on how to make a mold for a piece that will be hollow but you need a constant wall thickness?

Would it be appropriate to produce a wooden Master with a CNC Cutter and use that to produce a proper mold? :o
Great video Bill! i've been looking into building a mold and trying to cast some sort of resin, which smooth on product do you use for the casting part of proms such as a gun or a light saber?
what is the biggest mold you have done, what was most challenging mold (&why) and how big is TOOOO big?
I've noticed you use a couple different fillers like Bondo and a white type. Could you give more info on what fillers you use and why? Also any tips on mixing filler correctly?
Really informative! Keep up the great work! :D
good stuff!

Yes, I've been wondering the same thing.. any reply?

hello, im going to build a gears of War suit for next years long beach comic con. is there any tips you can give me on where to begin?
I'm hoping to make a silicone mold out of some small items, like dice, nuts and bolts, anything realy,
to use ase a mold for like maybe chocolate or jello. I think it would be fun to make small snack like this.
but I don't know if silicone molds are safe to use for food?
***** thank you so much! :D
How would you recommend making a master hollow for LEDs?
I'm trying cast something that I can put around a bubble gun! :)
The back of the mask I'm trying to make isn't entirely flat how do i fix this in the final mold

I want to mold and cast a helmet, how do I create a master for the helmet? I can't find anything on this.
Punished Props thank you the help and the very quick reply. I'm going to start experimenting, hopefully soon!
I'm interested in this too! Does anyone have a direction to point me in?
is there a specific type of clay you use when mold making?
Does anyone know if making a master out of Eva foam for casting would work or is that a no go?
Hi Bill! So I'm wanting to mold a Star Trek com badge prop that I ordered out of resin so make it a bit more screen accurate, but I don't want to screw up the original prop. Is that a good idea, or should I just live with the finish it already has?
Punished Props okay. Thanks!
can i used styrofoam/polystyrene for the master mold and then make a mold using a silicon?
Sure!
thanks! will try it soon
Does anyone know where we can learn how to make a master? I haven't found anything that pointed me in the right direction yet. Thanks in advance!
