Thank you for Watching! Tune in next week for more videos :) - แนวปฏิบัติและการใช้ชีวิต
I think it's so rare for designers to show the mistakes in the process, and I truly appreciate you giving us insight into the perils certain materials have. I would love to see you explore past projects that have effectively "failed"; an exploration similar to the manner of the art of Kintsugi. I know my advice might not be compatible with your initial concept. I love your work and I appreciate the content you provide. Keep it up!
18:30 The most honest and true display of emotions ever seen on youtube
I felt it!
I LOVE the fact that you showed all the issues that hit you: those learnings are invaluable! Thank you!
Yep, you learn by failing.
Loooooooved that moment of pain after that "crack" and that disappointment face haha true feelings. Thank you for also showing the shitty parts!
so sad for me
But true moment and it's precious to share
That visceral anger and sadness when the chair snapped
Never thought I'd see that much emotion from him lol
We don't like to see your mistakes to laugh at your failures, but rather to know that you are human and make mistakes as well as us. Please continue to include them, as it helps me keep from stopping creating because it's not "perfect" the first time. THanks!
best video ever. Failing is always an option and nothing to be ashamed of!
Dude, for your first CNC project, this was amazingly advanced.
for the runners for the back, use 2 sheets at half thickness, glued together with the grain running perpendicular to each other (like plywood)
Or steam and bend actual plywood like Ikea's Poäng chairs. Sure it won't be a circular cross section but it will definitely be strong enough, also it's at the back so 🤷♂️
The mistakes and iterative process are a big component of the learning process, and sharing that with us is the difference between letting us learn with you versus just watching another maker make a video of something cool. Both video I enjoy, but getting to watch your mistakes is unique among the rest.
I was thought I was impressed with you. I REALLY became impressed when you admitted your multiple attempts and two-sided milling. Bravo!
love it how you are showing your mistakes, we are all learning a lot from it. keep it up!
Good thing you did not left out the mistakes, refreshing and educational. Great video.
I really like see the things that don't work. I learn far more by seeing what doesn't work and how you work around them
A bunch of TH-camrs think people like them to fail. I don’t think that’s true. We just learn more from the failures. As well, as a beginner woodworker it’s heartening to see that even the pros make mistakes. When we remember that us beginners don’t get as discouraged by ours.
You can use the large cutter for the finishing just with a small step over, this would actually give you a better surface finish than the small cutter due to the larger radius. Clearly if you have small corner to get into that would be a drawback as you would need to change out to a small cutter to reach into those spots. Nice work overall, always learning is part of what makes it fun!
ajajaja when i saw he did that i stopped the video to say the same thing
That scream and you yelling no sounded so incredibly raw. Oooooh I've been there before and I felt so bad seeing that shot. I'd love to see a version 2!
This was your best episode! A less polished final product doesn't make less quality content, au contraire
Man I love it how you're dealing with this designing process, it takes so much dedication and humbleness to not give up on the project and still present the results no matter if it fails, that's art
One of the strengths of your work is the level of accuracy and polish you bring to the table (pun intended) but it's actually really good to see your failures too. It reminds the rest of us makers that failures and mistakes are just part of the process. Nothing that is well designed was accomplished on the first try
Welcome to the life of product design. Everything is part of the experience, good luck!
Back when I was using a CNC router, I would generally run the toolpaths through a block of polystyrene foam to check them before cutting the final material. It's cheap, and you can turn the feedrates right up, saving time.
The electrostatic mess must be killer. I don't even like using MDF.
I built a beautiful "Maloof-style" rocker in a class at Marc Adams School of Woodworking about 8 years ago. He told us, and was correct, that a chair takes more of a beating than any other piece of furniture in your home. Leaning back on 2 legs will snap some of them (don't ask me how I know that at 6'6" x 310# LOL), twisting in it, etc. Of course I had over 200 hours of filing, sanding, shaping, finishing, etc.
I appreciate you showing the fails as it helps the rest of us avoid obvious problems that were not obvious until you tried them LOL. I am sure your next version will be nice!
This is my favorite video of yours, not because of the failure, but the humbleness of the learning from it.
i like such videos.. showing mistakes and progress.. far more interesting than "perfect videos".
Failure is the real life. We fail all the time! I appreciate it much when people shows it. Cheers!
love the smile and the enthusiasm you have after broken the chair ;-) but the concept start with fails and wins :-)
hey man, you've probably worked this out already. but every time you hit the stop you need to re-home your machine. as soon as you hit the stop it no longer "Remembers" its position, you also don't know how many steps the motor makes after you hit the stop. great usage of pins for the flip. that's a very simple and clean way of doing it.
I just gotta say I love your channel. TH-cam recommended one of the 3d assortment box videos last week and I have been binge watching ever since. Only sad part is I only have a few vids before I've seen everything.
I love when your true self come back at 18:30. 😂 Awesome video, I also love the fails, when it seems like everything goes as planned for you, I feel so bad for my mistakes. Thanks for showing some of your fails, I also try to add them on my channel, people seems to like it, please continue !
i have learned more than by other "perfect" videos
Thank you for your honesty and actually stress testing your product !
The chair looked nice good luck on the redesign!
One way to try & fix the chair. Drill some long holes down the length of the uprights & just like the seat & back pieces, insert & glue a metal rod. Make the rod long enough, so that the uprights don't snap at the next weak point.
Another great vid by the way & looking forward to the next vid👍
I always hate you because the end result of your thought process is so damn cool, i really love that today you let us watch the middle of the process aka a couple of mistakes. So cool video!!!
Wow, it takes intense listening to fully enjoy this video. Well done for challenging me.
Great to see the failures aka features of the design and making of it, that makes it so real, and the actual learning is from mistakes. Kudos!
Love your presentation style, and showing that design is an iterative process, no matter how smart or clever you are! Thank you for keeping it "real"!
I'm excited for Version 2.0 of this Chair! :)
This was actually my favorite video of yours. When I saw the parts getting cut on the CNC I was worried about that short grain - I think if you did the back support the same as you did the legs that would probably work.
I find watching your fixes and re-design iterations both entertaining and interesting. Seeing some of your journey gives important context and so the final, finished product will feel more earned and triumphant. Thank you for sharing.
It is good to show mistakes so that there is a realistic expectation for others when they want to try making something. Only showing successes can be cool though learning through failure is something that is important to making and learning. Nice work and a cool project.
Another fantastic video. Fails are just more XP to leveling up. Love watching your editing to help me step up my channel. Keep up the great work love to see chair 2.0 in another vid.
I like that you have been open to show all the mistakes and lessons. I am going through similar experiences with my cnc - every new product is a result of several trials that ended up in fire pit.
Love it! great video and I feel your pain the moment the chair broke.
Thanks for sharing this type of video! It's much helpful to see all the things that can go wrong and not just a fine polished end result. I love your enthusiasm and looking forward to see the story of the chair continued!
Dude! this is your best video, when i make things i swear i have more problems than good results, its frustrating, but see you living the same make me feel really happy. The resilence making things failing in the process makes the final results feeling great. Again, amazing video!
Awesome Alex, the energy you put into these videos is amazing. You are by far the most entertaining woodworker to watch. Keep it up and good luck with the fix for the backrest problem
Time to learn about wood grain direction ;)
Most of the time, I'll feel down when I make such mistakes just because those I learnt from (TH-camrs) barely show fails.
That's really nice you included them in the video, I feel a little more confident now. :)
Sandwich some solid wood in an alternating pattern for the back supports, like thick plywood. Conversely you could glue the back struts together and route a groove and place a spline with the long grain running up and down.
13:17 "I just put everything back together and cried again.."
Man, I feel that!
But even through all those trials you got a great looking backless chair!
Hey, could lamented wood for the chair stiles work?
Hey Alexandre, really loved this video! It was great to see the whole process including the initial test runs and the failed attempts! Love where your channel has arrived! Also congrats on 300K followers! wow it's unstoppable now!
Alex is slowly assembling an art piece of chairs made with different methods and materials. I suspect the final form will be a chair made of all the other chairs.
Looks really great, can't wait for the next version
I loved this being able to see how you problem solve is amazing
I still see a stunning stool. Looking fwd to the next video.
Definitely steam bend with multiple thin laminations for the back brace, strongest by far. Chairs take loads of stress so build them tanky! Everything looks awesome and you are almost there. Good luck!
Thanks for sharing about the two sided process. I'm assembling a 4x8 avid pro right now and was wondering how it's done.
Great video, Alexandre! Looking forward to seeing your next version of the chair. 🇳🇴🇳🇴
I thought I was the only person crazy enough to use stepovers to create curved pieces 🙂 Super job!
To fix the back on version 1 of the chair, I'd glue the back on again. Then I'd cut vertical slots in the two supports. After that it's just a matter of cutting out a couple of thin pieces either of the chair wood or some contrasting material (walnut maybe?) and gluing them in - splines are used a lot in traditional woodworking to strengthen joints. I think that might work here.
Keeping going!! I love to see your design process - failures and all. Remember, each step is a learning experience
love this. Love it how you always put out projects that work so good and seem so quick and easy to complete. This is a great example on how does work well and not so well in the same video. Amazing how you're using pretty wood on a cnc router, I'd never seen that before lol, only with mdf and plywood
Thanks for sharing your failures, learn so much from it!
Jajajajajaajaj, always can't be perfect all the time. Thank you for showing us the mistakes in build, we learn from everthing even the mistakes.
Definitely not regretting subscribing! I think you’ve gotten better at this! The first video I watched of yours was the drill powered scooter or something and I’ve gotta say it’s gotten better and better since then! Keep it up!
Welcome to the frustrating world of cnc wood work 🤣 the first job I took was a paying one... And I very quickly realise the learning curve was steeper than expected
I sat for many years in a school dining room with Eames style chairs. Definitely need laminates to get the strength you need. The CNC would work well to custom cut the forms for steam bending and for the individual laminate pieces. Those chairs lasted for forty years until the school closed.
I don't see the seats that didn't come out the right way as failures, but as new ways to make unusual trays. 😊
You could also do a glue up of three flat pieces of oak with grains all going different directions and then mill it out with the CnC. This will give you strength in 3 different directions. Also, I would put the pieces that you used to connect the leg halves together on the outside. They look cool and you get added design element for free.
You should turn those failed wooden blocks into some wall lamps, or some sort of lighting devices where the light comes through the holes
Yet another great video, and seeing the mistakes of the design process is an amazing way to prevent those down the line. Cheers!
Such a beautiful design and a great project! Thank you for sharing the 'good, bad and the ugly'. I'm sure this will help me and others to think of all these aspects of the design and manufacturing process. Better luck with making the next version. I am sure you'll end up with a great set of chairs!!
After watching the video, the title and the thumbnail makes more sense now
Super video, I love to see WHY something fails and I appreciate your way of dealing with it. For version 2 I would do the backrest-holders each with 2 parts, strain going perpendicular - just like with plywood. Thus strength will increase.
Thanks for sharing this! Anything worth doing is difficult, it's encouraging to see really competent people also struggling sometimes 👍
For ver.2 why not make your own laminated plywood? Do some contrasting woods with alternating grain direction to make it super strong.
It could look amazing if you give it that ALCH touch!
steambanding would rock!
I think the right idea is a bridle joint at the "elbow" of those back supports.
amazing informative as always! Keep up the great work.
YES. A NEW VIDEOOOO
We demand a v2 of this chair
Nice. Lots of good techniques in this video
One of the ways to reinforce the back supports might be to use a "rebar" of sorts: drill down the vertical axis and add a steel rod, for example.
Excellent !!!
You open doors to a next level for wood furniture design.
Thank you to be honest and to share with us your mistakes.
In my opinion the steam bending is a good solution.
Challenging but elegant, it seems not to be an issue for you. 😉
For the next version, I'd suggest two boards for those back supports half-lapped together at 90°, then machine the pieces out of that. The grain will run in the right direction on both sides of the joint, and at the joint you have grain running both directions in the half lap joint. Quick and easy to implement, and should be strong enough. Half laps are pretty indestructible. Could go for a bridle joint if you want to double the glue area.
Superglue the back together again, drill down through the struts and sink some threaded rod and glue down in each one, and then plug the tops with dowel and sand it clean.
That’s how I’d fix this, and I’ve actually fixed something similar with this technique.
Hope this helps, I’m looking forward to V.2!!
I love the way he says “twogedder” 1:34
Hi Alex nice job so far. i was thinking of repairing it with two long metal pins from inside and covering tips with dowels. u simply drill through the broken parts from bottom followed by metal pins. not only fixing but giving it a good support. Although drilling will somehow tricky.
Drill up through the back supports and insert a metal rod. Plug the hole from the bottom and that should provide enough strength. Also I would carry the shadow line underneath the seat all the way around so it looks intentional.
Huge props for showing us all the mistakes! I'm thinking about buying a CNC machine myself and it really helps knowing that everyone else also messes up from time to time :)
Here's my idea for fixing the back issue: Each back support could consist of two halves glued together along the entire length of the piece. Then you would be able to have the grain for each half running in a different direction and thereby adding a lot more strength to the piece.
Good luck with version 2!
I have a new found appreciation for real wooden chairs. I do think steam bending would be the easiest way for what you want to be honest, but that's just going off of other TH-camr's videos I have watched. Still a really beautiful chair though! :)
We learn more from failure than success. This was a great project to follow. For the chair back supports try laminating a bunch of thin sections together. It will be strong and still quite nice looking.
Totally not a fail! Great design, cool video & I've learned a lot about woodworking and CNC'ing from you :-D
I think you could use the threaded rod dowel method to fix that chair to give it extra structural strength. Drill a hole into it from the bottom using a long drill bit and thread that hole. Fill it with epoxy and put your threaded rod into it. Plug the holes with oak dowels when the glue has set
Great video, I think there is more to learn when things go wrong and you make it really entertaining to watch.
To fix the chair, maybe you can drill the back supports from the top, add a small metal beam to help the load and use a wood plug to hide the hole ?
The five stages of grief:
18:32 Denial
18:29 Anger
18:33 Bargaining/Depression
18:34 Acceptance
The chair looks sweet. Thanks for sharing all the lessons learned. I don't think I'll make a chair, but will certainly apply your tip on how to CNC two sides of a material. Cool stuff as always!
If I was you I would drill channel into back rest support for some metal rods. Not only you would save your project, but also you would strengthen it significantly.
Maybe you can save the back by gluing it back together and reinforce it with splines somehow.
Any way, great video and keep on making 😊🇳🇴
