Especially on a lathe, you can't just measure a part for size or fit while you're machining it. It will be heated up from the cutting, and you have to wait for it to cool back off before measuring with calipers.

For anyone else: Consider trying with fiberglass instead of CF. Materials are much cheaper and the techniques carry over.

That first mold should've been three pieces. Solid inner plug and two part outer (2x L shaped pieces.) Lay up on the inner then add the outers and clamp everything together.

Anytime someone wastes 5 seconds at the beginning of a video like that I instinctively close the browser tab

The fact that you made your own parts without 3d printing is cool af. Wish i could make them like this and not from petg.

Is that scene from the resident?

I really love your video, and I am electrical engineer at IIT Gandhinagar, I am also interest in robotics , I feel like I can understand the amount of the work that you put in it, and which is really a lot, even I haven't seen engineers who put one- tenth of effort in anything .Actually love the cinematography in you videos, infact I made my first - zero budget - short film at my college, th-cam.com/video/4udZUGtepaM/w-d-xo.html please do watch it if you have time and let me know

I hope you are using a respirator while cutting the carbon fiber

I cannot wait to see the final product, it's clear you put a lot of effort and love into this project. So far it's looking incredible, hat's off to you sir.

Hi, I found your material very interesting, espesialy because i also built something like this as my master procjet (but of course in much smaler scale). I also have problem with mechanical conection between two axis and also consider compensation it by program so i'am really interesting if you could tell me how you done it? Or maybe even shere a pice of code?

Great video! What are the animations made with?

Nice work, I'm in the midst of doing something very similar, building a 6 axis robot arm to hold my camera. mine is also a v2 ;-) I'm a little further a long in terms of working pieces, (though perhaps not by now) but quite a bit behind in terms of machining. my plan this time is still 3d printed parts where they accelerate process, then remachine in aluminium when they become a problem. Do you have plans on your control setup?

Carbon fiber (and composites in general) is one of those things that is so simple in concept, but can be a nightmare in execution to get right. Love your channel

I have been building an Annin Robotics AR3 arm to teach myself coding. Has been fun. This video keeps my drive going thanks.

Based on my experience, it's always best to infuse resin along the direction of the unidirectional fibers. Another important point is to slow down the infusion rate so the resin can thoroughly penetrate the fibers; otherwise, it can overflow the fibers and trap air bubbles. As you mentioned, infusions can be challenging, and maintaining a clean and precise workflow is essential. For the new mold, I’d definitely recommend using fiberglass. If there’s a leak, you can simply double-bag the entire mold. This approach should make it much easier to achieve a perfect vacuum.

1. Hi, this is a very good video and the product that you built is also very good. From an environmental perspective I would say go for aluminum because its recyclable. Another reason why I would choose aluminum is that it can carry more weight, aka more heavier cameras than plastic. 2. Cinematography is not easy, no matter how many robots you make, you will need people for makeup, lighting, coordinating with actors etc., so you cant rule out human staff completely, if that's what you mean by 'pay, dignity' etc. 3. I am really impressed that you dabble in robotics and engineering although you're a cinematographer by day. James Cameron an Oscar award film maker scoured the bottom of the Atlantic in a submarine to study what actually happened to Titanic, before he could make the film. He is an engineer by education by the way. So there's no hard and fast rule that if you're a film maker, you cant engineer products and vice versa. Its the passion to do something good for humanity that counts. 4. Its not 'Lowering your standards!' Its lowering your specifications. Its not 100% calibrated? Of course it wouldn't be. To be 100% calibrated you will have to spend top dollar. Kindly request you to speak in a little more polite tone versus the sarcastic undertone / overtone you always use in your speech. 5. I have just started my climate engineering and technology startup and have a team of 279 scientists and engineers and will recruit more around the world. PS - There's no such thing as a perfect product. If you keep calibrating, you will run in circles. Make the first version, use it, sell it or rent it to other film makers. Get their reviews and develop the second version. Intel made 386, 486, P1, P2, P3, P4, Core i3, i5, i7, i9 and so on and so forth. If large behemoths like Intel who have thousands of super smart engineers take time to develop their products, then you and me are nothing! We are standing at the end of the line my frend.

very nice video I'm a robotics enthusiast and I don't know where to start I came across your video which had a lot more impact on me please is it possible to have more details to be able to make one like yours

Composites is the sorta thing where you kinda have to suffer for a bit before you appreciate the medium. Hot resin actually flows much better and its common practice to actually mix and start flowing the resin on the cold side before passing it thru a heating process immeadiatly before it enters the mold cavity. Don't feel too bad. The marine industry has sacrificed an obscene amount of hulls figuring out this process. Some even made it into customer's hands.....

The shots at the end were cool and all, but I feel like it would have been better if you used some sort of automated camera arm

It's your tape and glue clamping that is allowing for some shift which is why your circles and dimensions are ever so slightly off. Not An Engineer had a similar problem. The glue and tape are both flexible.

You may not be an engineer but you are very good at mimicking other TH-camrs. I hope you fine your own style.

+10 for the Dunning Kruger reference.

Nice Video! 👍Hopefully you will show how you made the final shots! Was it “Marge”? Did you run the camera yourself? Did you pay someone to do it? Or was it “Marger” from the future? 😲 Did you leave the reflections in the glass to chance or did you coordinate it with the camera operator?

Oof yes been there. Thought I could start a composites company, because I’ve watched all easy composites videos three times. I failed hard. Really hard 😀

How can i build my own?How can you help us out ?

great

few videos is so enjoying to watch. I going to see every video from you

I have been there. West Systems Epoxy and 209 extra slow hardener is a much better product for warm weather layups. It takes so long to cure you can mix up a second batch in the middle of a pour or layup with out the part you are working on settings. I don't have a shop or a table inside and I can actually make parts outside in 80+ degrees. With that product. As well even after mold release a epoxy continues to harden for 3 days to a week. You should find your piece much stronger than when you first released it. The pinholes in your infusion are not a problem for structure but they will be for making a mold. You can use an automotive epoxy clear coat (1k) to fill the voids and provide a perfect finish with MUCH less work then surface epoxy.

Good job 👍👏

The best content on 'machining TH-cam' at the moment - I really appreciate your ingenuity, honesty and beautifully lit/shot/edited pieces. Having done some recent work with resin restoring a dragon boat, this video got me right in the feels as the kids say. Keep it up Steven!

Awesome build! Lmk if you need any parts machined in the future. I’m a camera guy as well but have a Tormach 1100MX. 😊

❤

it angers me that we don't have affordable camera robot arms yet

Just found out your channel.... BRO, your voiceover and image quality is stuninng. addictive even for experienced cnc shop owner. Keep pushin

Given the amount of curing timing mess up you did, the first attempt result was extremely good. We had an idiot do the same thing when we were making our rocket body with a mold he forgot he had to start a timer for the resin curation debut. The waste management was crazy difficult.

6:28 what software is that? Fusion?

He wasn't kidding about the sexy parts montage It's like he does it for a living

Why build the robot from scratch? I think the best thing to do is buy commercial for example ABB robotic arm with broken/obsolete electronics, then you give it some refresh/cleanup and drive the OG motors and encoders with modern compact electronics. I didn't look at prices but I would imagine you can buy $100k robotic arm that is old and broken for like $5k or less. Regarding your first cf part attempt, you made a lot of mistakes totally on your part, I never made a single cf part and I could see that with this mold design the cf would get just shoved down. Using quick cure epoxy in a got rooms is also an obvious mistake. You also gone with wrong technology for this part, with shapes like that and need for smooth flat finish on both sides, you should've gone with forged cf using chopped/tow cf and like 6 part mold.

An experiment in not following directions

Awesome video ngl !

Love your style! The bluish tones, smooth music, your narration, and honesty about little mistakes make it so enjoyable!

Didn't look like you degassed your epoxy before infusion, bubbles are likely just coming out of the epoxy. Lots of gas gets trapped inside it because viscosity. You can improve the appearance by painting a couple thick clear coat layers. Even just rattle can clear with a steady hand can easily turn the worst carbon fiber part into a thing of beauty.

Man, I feel for ya!! When I started making carbon parts for big R/C gliders it was a steep (very steep!) learning curve. I got there eventually though through just dogged persistence. To be fair to Easy Composites (with who I have no personal connection) they are local to me and so often go to pick up materials in person from their trade counter and to pick their brains. I often talk to Paul that does the instructional videos and he is more than helpful in giving advice and inspiration. They do though make it look easier than in real life as you showed in this excellent and very entertaining video. Keep at it fella and you'll get there!

This was amazing im not sure how i havent came across your channel before but you best bet im subbin now

So funny and educational at the same time 😂. I subscribed and liked.

Your videos deserve an Oscar, this is incredible!

Oh man, if I’m honest this is how the large majority of my projects turn out. Marginal partial success after 10x the work you expected

I am a robotics system engineer. This is great stuff! You could just buy a used robot for a few $G's, but where's the fun in that.

A lot of people think this stuff is easy, and they make a mess. But to be fair, you really aren't that far off. Give it another try and you might surprise yourself. And just FYI, for the first part, the main thing I would change is to use what they call "Wet Preg" technique...which is to lay out the fabric on a plastic sheet and apply resin to each piece individually, squeezing out excess epoxy with a squeegee...then stack them together, wrap over the inner mold, and stick it in the outer mold. The release issue was most likely cause by micro porosity in the mold surface causing mechanical bonding. So use that release film on both sides of the part. Some small surface defects are normal. Perfect shiny carbon parts you see have undergone a lot of finish work, sanding, clear coat, etc.
