Watch Adam and Bill Doran make Ringwraith gauntlets out of foam! ua-cam.com/video/F48rk7h-GDo/v-deo.html
Watching this video is so fascinating because it feels like watching two people who have a life time of interviewing experience but have 0 chemistry so they carry the conversation with the correct things to say but it feels like such a lifeless performance.
Lmao
To get a volume for the pour of silicone, just fill the empty mould with rice grains and then tip them out into a measuring cylinder.
I know this is an ancient comment but as someone who's starting to dip further into propmaking, this is genius and I will apply this idea later lol thank you
But some if the rice but not come out and your mold will be messed up
You just changed my life
I make these type of props for film and TV. I wanted to point out that if someone is going to add a stiffener or something to make the handle ridged like in the axe , please do NOT add metal or a chopstick as they mentioned. If you are making these types of props for stunts that is dangerous. The wood can break and then becomes a sharp one that will hurt someone. Same with adding metal. I have found that using a fiberglass rod about 1/4" thick is a great option. To keep it safe I add the little rubber end caps to protect the end of the rod from poking out and hurting someone. They will flex but will not break. Keep them about 1" from each end of the prop. Again to keep it from becoming a stabbing hazard. For a cheaper option, You can find these rods in kite kits. Even at the dollar store places. I found a great way to hold the rod in the center of the object is use thread to suspend it in the middle. Tie one at the top and one at the bottom. Run the thread across the middle of the mold and tie it. It should look like the rod it floating on the threads suspended in space. This way it will not move when the foam expands pushing it to the edge of the part.
I hope this helps and keeps your stunt weapons SAFE above all.
Can you *PLEASE* Do a Video?
I'm not understanding the Thread Part.
(I am a Hands on and Watch Person than Read from a Book and Fail to disappointment Person).
I really second that. I understand all the processing except how to put the rod. I want to make LARP weapons, but that thing is the most hard for me. I would really apreciate.
Great advice!
Hi. Thanks for the advice… but isn’t fibreglass just as dangerous? I’m really struggling in finding a safe reinforcement
I would like to make a cain. I was thinking about using handles from a chimney sweeper. But I think it may be too rigid. Are you suggesting something like a fishing pole?
Respect the Estwing axe, quality american steel and workmanship and thats coming from a roofer who is in the UK.
Only Gränsfors for me thanks!
I'm a big fan of Estwing's hammers. They make good tools.
Never seen one of their hammers break, only the handles with extreme use and the leather with heat and age. Quality tools.
Those iconic handles
It's nice that one or two things are still made in the US.
Has Craftsman gone 100% China at this point? I know a couple years ago I couldn't find open-end wrenches made in the US, which was a pain because they had to increase the thickness of the ends to make up for the inferior steel and therefore they didn't fit in foam wrench organizers
I think Norm is doing a great job. While he isn’t the best he represents a lot of viewers who may or may not be educated in these topics. Asking simple questions and explaining certain terms related to the project is extremely easy for me to follow along.
"Who are you?"
"I am you, but floppier"
Limp axe. -2 compensation bonus.
This doesn't work as a pick up line. I tried.
Rex Talon why didn't it work
Because I'm not rich enough
Thanks for such a clear overview that answered a lot of questions as I embark on a mold-making & casting adventure!! Sidebar Story: When covid hit, my business of 20 years went straight downhill. Ironic because I design trail maps for Ski Resorts :) So like so many other small businesses, I was essentially shut down. With more time on my hands, I had an idea one night (beers were involved) to carve tikis with a chainsaw - although I'd never used one, sell them locally and use the money to buy lunches for our amazing local Healthcare Workers, Nursing Home staff, homeless shelters, food pantries and other causes of import. My family & I started Tiki Task Force with this crazy idea and it went bananas! Very humbling. At any rate, I'd love to see about creating a mold & casting some of the carvings I've done! This seems like a perfect way to reproduce these pieces, sell them on a bit of a bigger scale and be able to contribute to more & more causes! So thanks again for the insights!
Do more things with Adam, he's the only reason I watch this channel!
I feel like if they sent Adam for this episode he would have died from excitement or refused to leave and moved in.
Well, Norm is getting better. Still stares at people like they have food on their face, waves his hands around like Ricky Bobby in an interview and occasionally makes rather pointless statements. But he's improving. Frank knows his stuff and does great demonstrations. He also doesn't break 95% of shop safety rules like Adam does. Every time I watch Adam use a lathe I wonder if the next thing I hear about him is in a headline or an obituary.
Nick Sushkevich Norm is so cringey I bet his mom paid them so he can film with them
My number 1 problem with Tested is Norm
I wish Norm would actually apply some of these skills he is (hopefully) learning. It would be a huge shame for him not to learn this especially since he has access to people who have worked in the industry. That's priceless.
Not sure why everyone doesn't like Norm! He just makes sure that the audience knows what is going on, explains things for us. He helped me understand some of the lingo and techniques Frank was using, because for him, its second nature just to do his own thing and not really explain much. Norm is just doing his job, which is hard, because he has to tie the conversation into his questions.
The axe's handle isn't wrapped, it's actually a stack of leather discs. You can see how this is done if you look up "How It's Made Axes".
M. J. B. Stfu with how it's made? Tyty
M. J. B. I remember seeing that episode with my dad!
when I watched this about 5 years ago, I said some negative things about the dynamic between these two. I've been through a lot since then; we've all been through a lot. I just rewatched this video, and YT showed me my comment from 5 years ago. I didn't recognize myself anymore. I didn't like what I had written then. people can change.
you know what? this is a helpful tutorial, and these guys are doing their best to make this information accessible. good job Norm. good job Frank.
Frank is definitely my favorite tested member
THIS is the kind of content that keeps me subscribed to Tested. Thanks, guys!
I have never liked this type of mold. I tried it a few times but always resorted back to standard part molds. I find that cutting into the silicone creates too much of a chance of destroying a nice mold, or worse cutting your original piece.
Plus....this way takes a LOT of silicone, which is really hard for anyone working on a budget. It makes more sense to me, to use less silicone (enough to smooth undercuts and such) and back the outside up with a jacket of fibreglass or plaster. That way you use less silicone, and you can be guaranteed your silicone will not warp or bend out of shape.
Adam is a busy guy, he can't be in every video. Enjoy the free content you're given. Love seeing Frank work and Norm asks all the right questions that give us all the information we need for the process.
This.
I like what CGI and Green Screen offer, but THIS is the kind of thing that makes me want to make films! Thanks for the very informative video guys!
They came out awesome! Great work guys!
When you make a video like this show us the de-molding and the open mold.
20:16
i think he hacked that mold! that why he didnt show it. what a bozo! and the plaster tape? what the?
I don't think he gives a shit what you scrubs think. Make better videos then we'll talk.
@@user-ce2br4wn7f For me, I'm watching this video to learn how to do it, and im a bit confused, so I'd like more detail.
great video. i really enjoyed that you asked detail questions and pointed out things that were getting glossed over. thank you
Yes! These are the kind of videos that first got me into tested. Keep it up, and keep em coming guys!
9:16 "I made a little bit less than I needed, just in case.." Interesting phrase xD
Very cool. Only downside is the cost of using pourable rubber and these foams for this for hobbyists. The finished hammer turned out great.
So happy to see more content like this again on tested!
MORE ONE DAY BUILDS 👍
Ibbo Beast they had to wait overnight lmao
still woulda been under 24 hours tho
Ryb
Ellion
Bandar.ghg Almutairi iii
The only way could tell the difference between the real and prop hammer was how the weight of the head balanced the rest of it xD it was so good!!
This is amazing. Looking up how to make some props for Halloween and this is EXACTLY what I needed. Thank you!!
This was so good. Loved it. Thanks for the awesome video tested team.
Great to see building of anything again , this is what drew me to the site in the first place,
Missed these projects with Frank
I actually really like the dynamic between norm and frank :)
Thanks for the video! Please never stop doing this!
I've been waiting for this video for SO LONG. THANK YOU TESTED!!!
Yessss thanks for doing this. Working on a few cosplays at the moment and this will help me out a ton.
That pin trick is brilliant!!!! THANK YOU THANK YOU!
OMG that axe is an Eastwing!!!!!
And it looks like it's a 1950's Eastwing!!!!!
And Frank just submerged it in silicone goop.
I'm so pleased the leather handle wasn't affected!
The handle is made of leather strips, layered together, with the tang of the axe going through the middle. The white layers at the front and back of the handle are ivory slices with ebony between them.
Absolutely classical and beautiful.
I would love to have this axe, to go with the matching hammer I have ;)`
These came out so cool! I didn't expect them to be so floppy! =)
Pretty brilliant how they do this, great vid, thanks!
Impressive!!! They look very real.
& no one gets hurts on set!!!
Mad props to these guys.
Frank's T-shirt is the best. Paying homage to the greats.
Many people are criticising the interviewer (Norm) for asking questions. Maybe you already know all about the subject matter of the videos; I would question then, why are you watching the video?
My experience is that many instructional videos consist of the one person demonstrating how to do whatever it is. Though they MAY be knowledgeable at what they are doing, they too often, don't know about teaching or instructing, so they don't explain what is going on. You'll find their video comments are full of viewers asking questions about aspects that were not properly explained.
Norm asks questions that are very relevant and he seems very good at identifying aspectss that need further explanation or reinforcement. This is very useful for viewers, like me, who want to learn from the videos. Instead of the comments being full of people with unanswered questions, his videos comments are from opinionated 'trolls' who have nothing better to do than mock. That behaviour should have been left behind in primary, or grade school. If you know-it-all, why not make your own videos? At least have the grace to 'keep your mouths shut'.
How cool is that ! Thank you for sharing this knowledge and video ! Would you use the same technique to mold and cast a piece of flat and round piece of wood carving ?
Just what I needed! I want to make some foam 45# plates for the gym!
Norm,
The subject matter of your videos are awesome and entertaining to watch.
However, your interview style really leaves much to be desired. It might be better to go with more open-ended questions (Why/What/How/Where) instead of simple yes/no questions. Allow your interviewee to form their narrative. Don't form it for them.
Aside from that, thank you for these videos!
Michael Uy he's so much better in tech interviews. Norm is awesome, though. Will would forget he was doing an interview, or that another person was there, and just keep talking and talking.
i normally dont catch onto his shitty questions, but this episode was a kick in the nuts to me.
I'm glad I'm not the only one it bothered.
I agree, Norm is pretty much the least interesting part of Tested.
He's always been like this. He's gotten better, though. Still, Norm really needs to talk less and listen more. Still does a better job than I would!
I love how the silicone looks when it ripples down into the mold
Very good show, clear mastery (on both sides of the camera).
Cool to see a different method of molding - but why would this not have been a candidate for a 2-part mold? It seems like, other than time, it would have been better to work with this horizontally and block off the lower half to pour that first layer and avoid bowing sides. Thanks!
Robert Sloan technically it’s faster since you don’t have to wait two separate times for the silicone to cure. If you’re in a rush, this kind of mold is fine but I do prefer two part molds if you have the time.
No ads! Thumbs up just for that!!
Hit norm with the hero copy!
Amazing work!
“You have an actor swinging around an Axe make a rubber one”, that’s a lot of effort and work making a rubber actor.
WOW.. incredible good walkthrough :) thanks for this. thank you TESTED..
Imagine that everything, EVERYTHING you saw in Lord of The Rings had to be done like this...
Imagine that everything, EVERYTHING were as floppy as the hatchet...
Yes every hunk of metal was probably foam. As Adam has stated, if you see a gun in a movie or a TV show and its actually not shooting at something, its a rubber gun. Its amazing that what sells these props is half the looks and half the foley sound effects.
Even though most sword experts cringe when the they hear the pretend "shwing" sound as its being drawn from a scabbard, we need to hear it so our mind thinks that a real sword and it can kill things.
I thought a lot of the weapons in LOTR were crappy metal props that had to get replaced all the time?
Wartooth91 I would assume any close ups of edged weapons would be metal.
i wonder how did the actors breathed when their moulds were being taken
Really impressive. Thank you.
Dont know why but i feel so relaxed watching these videos
This stuff looks so satisfying :)
What kind of paint would you use to paint the foam, and is there a way to dye polyfoam if you wanted one full color?
such a great trick this one with the pins! cheers!
thanks for mentioning the type of silicone. was wondering about all the materials and stuff
Damn, the sound of foam core being torn off of silicone is a satisfying thing to hear. :D
Morgan Weber I actually like the sound of the cracking plaster bandages. Kinda want to crack them myself.
This is one hell of a good video. Thanks guys!
That is a really nice job there.
Awesome paint job!
Thank you. I'm making a movie about killer eggs and need rubber egg molds and this really helped me. This is a 100% serious comment
Very cool. Thanks for sharing!
learned a lot. thanks for making this video.
Have you ever had any problems with damaging the hero props?
I'm thinking of molding some cosplay props in the future, but with not having any experience damaging the hero props worries me a bit.
Any help would be much appreciated.
Thanks and I love the videos, keep em coming.
Nice vid. Also, great Jack Burton t-shirt!
Ahh the Estwing camp hatchet. I love mine!
I am a fan of Frank. Frank is awesome.
Nice vids, very informative. Kudos to the prop-maker and his excellent work, I'm a photographer and recognize a real artist. I do have a question. The foam he uses. Can it be used in a lost foam meltal casting? I can carve Styrofoam, put it in sand, fill it with molten metal which vaporizes the foam and makes the object but I have something very intricate that would be impossible to carve using s cast of a particular object. Wax is iffy but a liqquid foam might be the ticket.
Franks shirts in this video are the best.
I love his t shirt, the pork chop express. From the classic movie ( big trouble in little China)
Holy fuck... I started watching this like "How do i know Frank?" - then I realized he was on the first (and 5th) season of Face Off! So awesome seeing how far his career has come
Beautifully explained..
Oh Frank, from Face Off! Cool. Was very surprised to see you back for a second time but it was nice to see you again and get to know you a little better and I was so sorry to hear about your father. Anyway, cool props and terrific paint job.
Very cool!!! Liked this a lot!!
Love this channel!
I like how Frank reused the foam core from the shop tips video where showed off different nozzles for spray paint. :-D
It looks pretty amazing for a foam copy. The vast majority of people would be totally fooled by either of those but particularly the hammer.
Thanks for the help!
I don't ever plan on making a prop but damn are these videos entertaining and informative!
I think Norm is honestly getting better at hosting these videos!
How do you keep the paint from flaking or coming apart with use, or is that not an issue?
WOW THAT HAMMER LOOKS REAL GREAT JOB ! SO I SUBSCRIBED 👍👍👍
If this was King Of Random this would have been two weeks worth of content :D
That Estwing hatchet's handle isn't wrapped but made of a number of stacked disks of thick leather.
Those stick pins that you used in your mold to secure things. I know that they're originally for sewing. you could find them in the sewing section at store but my point being is that those little stick pins with the little different colored balls can do some ridiculous damage when muzzle fed into any BB gun. Pump rifle I believe would be the best. Try it sometime.
Caution: It will go Through Skull!!
when I made molds for small object I used a pvc pipe, split up, kept together with ducktape, its very simple and once I use the mold the pvc pipe is good to keep it intact.
I can't stop laughing at the floppy axe :)
I would love to do this kind of thing, but I can't afford the nearly $200 of silicone they used to make 2 small molds!
Anything you want to do a one-off from will be expensive. Idea of molds is so you can use it repeatedly and make multiple castings.
It's just odd that they present this as a DIY thing, which generally means "cheap and easy". Now using expensive tools isn't that big a deal because they just speed up the process, but gallons of silicone and mixtures of foam and even the plaster braces are way more expensive than getting a pack of puzzle mats and cutting them to size like a lot of their projects...
but a lot of that cost came from using a block for those handles. like he said, it's time vs money. if you took the time to make a mould that was closer in size to the object, you'd use half (if that) the silicone.
modelmakers spend $100 on paints quite easily, as well. so that's not particularly outrageous.
James Dreger In my opinion DIY doesn't mean it has to be cheap. They use stuff that you and me could buy if we really wanted to make a mold out of something. It's not some crazy 5 axis CNC DIY that you need years of experience and a lot of money.
It doesn't have to be "cheap" exactly, but usually the purpose of "DIY" is to save money by doing something yourself. This video is a fine example of "how to cast foam props" but not of the DIY idea. Which I realize isn't part of the title, but it *is* how it's presented.
THATS SOME NICE LOOKING GOO
Great video guys
Nice! Any tips for casting antler sheds? Specifically the separating of the mold and best material to cast out of. We want to paint them and attach them to a headband so they would need to be lightweight, stiff, and have a paintable skin. Maybe a link to a good website with tips? Thanks.
When he is vacuuming out the pink slime it looks like I should be calling the Ghostbusters and getting Dana Barret out of her apartment.
I think that the blocks of cured rubber looked like BIG blocks of BAZOOKA JOE BUBBLE GUM. Lots of chewing for these pieces!
Seems like a box with adjustable corkscrew sides would really help with the bowing on different sized projects.
Very cool! I like the Pork-Chop Express shirt!
You guys are awesome.
That zigzag-cut strategy is so genius.
