I did a casting once that was 50/50 resin and iron filings, and not only did it have a lot of detail, but it felt heavy, polished up like, and even rusted like it was solid iron, very cool. Loving this channel, Chris!
As one of your earlier Explaining Computers subscribers, this feels like Christmas all over again discovering this channel - except this time it feels like I'm watching young Christopher with his toys. Absolutely love it!
I said it before and I will say it again - the world needs more people like you! Thanks for the new channel. For some reason I want to describe it as an interesting hoot!
Thanks Chris. I knew about rotocasting for large objects like plastic water tanks. Bur I never considered it for small parts like this. Could be a very handy process for recreating vintage car parts and vintage radio knobs where I want a solid brass inner core, but a fine detail resin outer piece. The outer could be made first, then have the metallic inner structure set into it with a small second pour or even some glue. It would have a much higher success rate than trying to make it all in one hit the first time as Deformities and air bubbles seem to hide in solid pours.
I've been using a mix of premade kits, 3dprinting and kitbashing to make model tanks. This is giving me ideas for getting realisticly cast replicas of cast parts.
Thanks Chris for showing us an interesting technique ‘Rotocasting’, I’d heard about it from a Model engineering magazine (UK) back in the 70’s! I like the Storm trooper helmets that you’ve made, achieving a good finish after all the fettling & painting, this is definitely an 8 on the CB excitement scale. Now we’ve got a new name to add to the repertoire, ‘Mr Spinny’, pleased to meet you! It’s got me thinking about making some model railway wagons using resin & a mould, I’d have to be careful that the resin didn’t pool too much in the corners though it wouldn’t matter if it was a covered van. Excellent video
Wow, this just reminded me of a toy I had as a kid. Were almost the same age so you might remember it? I think it was called "The Skull Machine" and it made plaster rotocast skulls and monster heads. It comprised of several plastic 2 part moulds that went in a clear plastic sphere which then went on a motorised base thad spun the sphere around random axises until the plaster set. Well until you turned it off, but you know what I mean. This went the way of most of my stuff, including my COMPLETE 2000AD comic collection 🤬 when our house caught fire. My Acorn Atom survived, though I'm not sure where that is at the moment. Thanks Christopher! Cheers 🤘
I see a video by Chris Barnatt that is not about computers! Yeah, I'm going to like this, and subscribe. I worked for a while at a plant that did what we Americans call "rotational molding" using polypropylene. The setup for that is a lot more complex than what you've shown us here, and, so, is unsuitable for the individual maker. (The molds have to be heated and rotated evenly, and cooled at a very controlled rate.) What you have shown us here is that, using commonly available materials and simple hand techniques, one can achieve results on par with much more expensive commercial methods. Very neatly done! I probably would have over-complicated this by trying to build a ring fixture to which the molds could be affixed so that rotation was more consistent, but your results speak for themselves. The advantages of that production line are the repeatability and sheer volume of production. A line making five gallon fuel containers could pump out around 500 of these each day. We operated four such lines, and two smaller lines for the caps, pour spouts, and other fiddly bits like the vent covers. The moldmakers' shop stayed busy with repairs to these molds, and usually had several spares in various stages of rehabilitation.
Annother fun video Chris! Well appreciated. I have made hundreds of Tamiya plastic models, special insteadlizing in tanks and dioramas for World War II. The miniature world is so much fun. Miniature figures from lead soldiers to plastic have always fascinated me. I always thought the model makers missed out by not adding computer instructions instead of paper.
Thankyou I'm really enjoying these video's and reflecting on my childhood........I'm 63 now I must look out my scalextric, trainset, Meccano and Lego!!
Still got my Hornby Dublo 3 rail train set, from circa 1954. Still runs. I have in running in the garage.. even the eldest grandchildren have grown out of it! (X box & PS).
Thanks Chris I worked for an Injection molding shops when I was going to school, while we didn’t have any rotation molds, this brought back memories just the same…😊! Have a great day!
2 absolute hits from 2 videos! Well done Chris. Your enthusiasm and presentation is second to none. Your childlike references are endearing, light-hearted and fun yet the video is perfect for those in most age brackets from kids who can responsibly use the stuff in the video right through to people in their senior years, enjoying reminiscing their younger days. I really hope this channel does great numbers, and I'm glad to be an early(ISH) subscriber!!
I really enjoyed your more relaxed and fun approach on this channel. You've also reminded me of my own teen experiences with decorative resin casting where you start with pretty objects in clear resin and then pour coloured resin on top to form a backdrop. It's made me want to muck around with resin again!. I hope kids see these new videos as well as creaky types like me
I used to work with hearing aids that were in-the-ear shells. We would at times need to make them larger to fit better in the ear. We would coat the shell with UV resin and rotate it on a slow turning motor while a UV lamp set the resin. If the mold you used was very transparent you might do the same, or have the UV lamp inside the mold. Very enjoyable video.
An interesting addition to your Channels Chris, especially liked the little stationary steam engine. Although the theme music is giving me flashbacks to music on films I used to have to watch on my yearly RAF Military training.
always wondered how this was done, very interesting, thanks for the new channel Chris, always interested in your videos and have watched I think every one of your explaining compouters and explaining the future so this is another great piece of work
[Watches my weekly EC and hears about Christopher's new channel, Immediately stops watching that episode to subscribe and watch all available episodes here] When I heard about this channel and what it's about, I was immediately excited! Then I watched all available videos, my expectations were greatly met! I always wanted Christopher to make videos on things other than computing. Don't get me wrong, I'll still watch EC, but a garden variety is something I always love, and look forward to each and every video henceforth!
Great fun.👍 i do a bit of 3d modelling and printing. I made a bust of my Thai Mother in Law by using a xbox 360 Kinect,3d printing it, then made a mold so i could make some plaster heads for her family. Very enjoyable.🙂
If I were to start this hobby I would use it as an excuse to get an airbrush. And I'd try to find a way to make an automatic rotocasting device. I love to automate everything I can.
Thanks so much for sharing this Chris! I've never seen this process before and it's indeed quite exciting - enough to perhaps try! Would you be interested to show us the process of making the molds as well??
I have 3D printed a Stormtrooper helmet that fits my head and the majority of the upper armour, I have filled and sanded them and painted them, I used various masking tapes for the painting of them with an airbrush in order to get the lines straight and correct, a clear coat is essential to get the correct look of the helmet and armour. Once I get the whole suit of armour completed I might have a go of making some molds in order to duplicate them should anyone want a suit.
No, Your Honour, I was just following someone on the internet to have them explain computers to me. I had no idea that this was just a gateway to building an army of storm troupers.
Hmm, I'm surprised that you didn't need a releasing compound on the latex. Gives me all sorts of ideas as I have some resin and hardener from an earlier job with fibreglass cloth. Just have to get some latex compound. The rabbit hole goes deeper...
Loving the new channel Chris. I really liked the new chapter indents, not sure what you would call them. The unpainted heads reminded me of the original Lucazade.
I remember as a kid trying to make a moulds using Copydex™. Would have probably worked quite well if I'd have thought to coat the original in some form of mould release first 😅
I thought "Stanley the Knife" was a bit odd, you have raised the bar! But it was fun to watch. I wonder if you can make a case for a Pi 5 with that technique.
Alternatively instead of cutting out the eye sockets, mask off the visor area and paint around. Only limitation is visor will be same colour as the resin
You need to make a rotocasting jig Chris. You could 3d print something and add a motor or naybe build something out of Lego Technic or Meccano. It would make a nice little project for your channel.
6:18-Dagnabbit, you missed a good gag between in that conversation between that mold and the helmet it sired: the mold should have said, _”I AM YOUR FATHER!”_ 😹😹😹😹😹😹😹
Another time forgotten excercise in what can be achived with a little knowledge, maybe you could have made a simple battery operated motor assembly to rotate the cast, so as to free up the need to manually stay with it while it cured, great channel so far, What next in the world of Chis! a lesson in chicken pie making?
First video I've seen on your new channel and what can I say, fantastic start!!!! Does anyone know any good RUclips videos for beginners on the subject in more detail?? Keep up the good❤ work on your channels Chris. All the best. 😊
Interesting vid showing v-useful process. Any chance you could show us the latex process too? Maybe a good topic for a further video? Thanks for your efforts Chris

They did the first new cybermen in recent Doctor Who using that method -- sometimes called "cold casting". I must try it.
As one of your earlier Explaining Computers subscribers, this feels like Christmas all over again discovering this channel - except this time it feels like I'm watching young Christopher with his toys. Absolutely love it!
Thanks for watching -- again! :)
Your humor is unmatched. I love it. This is an extremely interesting video.

"Interesting hoot". Yes, I like that! :)
Im so happy to see I’m not the only one with a full blown Peter Pan Complex. Great episode.!!

@@ChristopherBarnatt Thank you for bringing it to mind - that was some forty years ago? Something like that.
Another great video Christopher, thank you! Great to be introduced to Mister Spinney (with his sanding thingy) 😊
VISCOUS! 😂
Loving this new channel. Let's see how quickly we can get the subscribers up to 1M everyone. Come on. You know you want to.
1M would be cool! :) But I'll initially be happy with 10K, 25K, 50K. Well, yes, 100K!
Nice to see someone not afraid to go full-on geek! 😃👍
Ah, this is cool. Here I go down another rabbit hole.
Rabbit holes are cool! :)
Yes, but they are quite deep 😃
Let’s say it all together. Viscous! 😂
I wish you would have shown the latex process as well. I love the new channel!

Thankyou I'm really enjoying these video's and reflecting on my childhood........I'm 63 now I must look out my scalextric, trainset, Meccano and Lego!!
Those would all be cool things to look out!
Meccano was serious fun!
Another exciting thing was building a simple "crystal set" radio receiver.
Still got my Hornby Dublo 3 rail train set, from circa 1954. Still runs. I have in running in the garage.. even the eldest grandchildren have grown out of it! (X box & PS).
I'd love to see a video on your favourite sci-fi TV and movies. I just think it could be interesting/contain some hidden gems
Noted! :)
please add books to that list.

that dust will be great to clean off anything
Well, Chris has gone mad, hasn't he? This is rather exciting!
😂 waking up the inner (creative) child
Ah yes, this sweeps me away to my late teens..more or less the same age than the stars of the show. 🙂
Oh wow, 2 videos back to back!
You do spoil us chris 😊
I wanted to get this channel off to a good start. :)
@@ChristopherBarnattI'd argue this is a fantastic start!
You're smashing it (metaphorically) chris! 🎉
Rotocasting, never heard of it before. Fascinating! Appreciated this video. Looking forward to your next video!
Nice. I have been put off casting in resin due to the cost, this looks like the way to go. Thanks, very interesting.
Just found your 'bonus channel ' and enjoying it good luck with your new endeavour
Thanks so much!
Thanks for another video Chris. You're on fire with the new channel!
Thanks. :)
An interesting addition to your Channels Chris, especially liked the little stationary steam engine. Although the theme music is giving me flashbacks to music on films I used to have to watch on my yearly RAF Military training.
I am so stoked for the upcoming cartooning stuff! And Star Wars? OMG
Love this new style of content from you.
True.
Very nice, sir. You're a far better painter than me.
It is nice to see an oder side of Christopher... it is my second video of this site... fun as weel as the first I saw...
always wondered how this was done, very interesting, thanks for the new channel Chris, always interested in your videos and have watched I think every one of your explaining compouters and explaining the future so this is another great piece of work
Who needs a resin printer when you can do it by hand? :D
The end result looked great!
I'm loving this channel
Thanks!
Chris another very interesting video. This channel is going to be great!
You are spoiling us with content this weekend . Thank you very much.
I wish you success with this new channel 🎉

Good to see this has interest by the comments, but not for me.
An obvious suggestion for a new video would be to make a 3d printed roto casting machine. And maybe one on making the mould.
I do believe @TheCrafsMan would approve.
Nice. Better outcome than 3D printing.
That's brilliant! I haven't seen this technique before
Very nice, love the scale in the end.
Nice to meet you Mr. Spinny! I hope you get to meet Mr. Scissors and Stanley the Knife in the future :-)
He teams up with Stanley next Sunday . . .
@@ChristopherBarnatt Sounds like the beginnings of another RUclips channel for kids, 'The Adventures of Stanley and Spinny' :-)
Like most people I came here from Explaining Computers. Interesting stuff, and a nice change!
As an engineer, I appreciate your use of technical terms...like Mr Spinny. BTW...I would love to see how you made the mould.
From steam to stormtroopers. Sweet! And introducing... Mr. Spinny! With final finish by Phineas File!
Great video and you clearly enjoyed making it which was really coming through in the humour :)
Thanks for the video - Id love to see the mold making process!
I will do a video on making a mold. :)

@shaider1982 The Kinect isn't hi res as a laser scanner, but it works well enough.

Superb as ever - seconds in I'd no idea you could paint on layers of lacquer to form a mould. Thank you.
New channel, different content, loving it.
Thanks. :)

Spray paint. Works wonders for base coats.
I have 3D printed a Stormtrooper helmet that fits my head and the majority of the upper armour, I have filled and sanded them and painted them, I used various masking tapes for the painting of them with an airbrush in order to get the lines straight and correct, a clear coat is essential to get the correct look of the helmet and armour.

Thank's a lot Chris that was a very interesting video.
Loving the new channel Chris, never heard of rotocasting, may have to give it a go someday. Rotocast a raspberry Pi case perhaps?
A rotocast Pi case. Not there's a thought . . .

Hi Bill. Many people have asked about how I make the molds, so I will make a video at some point.
I thought "Stanley the Knife" was a bit odd, you have raised the bar!
But it was fun to watch. I wonder if you can make a case for a Pi 5 with that technique.
Excellent , thx Chris.

Indeed so! :) Thanks for watching.
Fuuny, there is a tiny mark on your table which I thought was a speck of dust on my screen. Went to clean it when it disappeared behind a helmet. 😛
Oh dear! :)
Hi Chris
You should make a time based rotating mechanism with a stepper motor and a Raspberry Pi in this channel 😀
Thank you for the cool video.
I hope you make a video on making the mould so I could have a try at rotocasting👍
I will do a mold making video. :)
this new channel is great
Thanks. :)
I imagined you were going to attach this to some kind of spinning mechanism 😂. Very interesting.
Hello, big greetings from Bosnia. Good luck with the new channel. I might even like this more relaxed format better. Wishing you lots of success!
Thanks! And greetings from the UK. :)
You need to make a rotocasting jig Chris. You could 3d print something and add a motor or naybe build something out of Lego Technic or Meccano. It would make a nice little project for your channel.
Be good to see these sent off to gazorpazorp or Luetin et al and see what paint jobs they can produce.
sponsored by Amazon 😉,I think most of my projects on old Amazon boxes too. Great video
This was excellent, Chris. Similar to how they made the heads on Thunderbirds. Can you show how to make the molds?
I will do a future episode on that. :)
6:18-Dagnabbit, you missed a good gag between in that conversation between that mold and the helmet it sired: the mold should have said, _”I AM YOUR FATHER!”_

Nice!
Used for making hollow chocolate Easter eggs, too..

Yes, the first 48 hours are encouraging.
@ChristopherBarnatt i have had my channel for 18 months and still not at 1000!! You definitely have good content!!
so cool! but I'm surprised you haven't created a little motorized rig to do the swiveling and rotating automatically!
Interesting vid showing v-useful process. Any chance you could show us the latex process too? Maybe a good topic for a further video? Thanks for your efforts Chris
Thanks for this -- lots of interest here for mold-making, so now on the list! :)
6:10 I'm sure theres an "I am your father" joke in there somewhere 😂
cool
