Very well said Jack, I'll have to remember this for the future. Also, thanks to Winston for the motivational pep talk.

My studio has boxes of "failed projects" Each and every one led to better technique and different approaches. Failure is one of the best teachers. Thanks for sharing one of your "failures". I look forward to your next project. I hope you enjoyed your ride.

My shop has a box of firewood :) I have no failures, just fancy fire logs.

Opportunity has not passed. This is not going away anytime soon. I'm a member of Annapolis Makerspace in MD, and the inquiries and requests from nursing homes, hospitals, and emergency services has only increased over the last few weeks. We have been using our resources to produce as much PPE as possible (3d printed faceshields, sewing fabric facemasks, etc) and cannot even begin to meet the demand locally. I understand the need to protect your mental health/sanity. I definitely go through all of the emotions, from feeling like I've actually done something, to deep sadness that I can't do enough, to extreme anger that it is somehow the expectation that hobbyists can solve a problem caused by our federal leadership who has failed us so badly. The unfortunate fact is that we are where we are and all of us need to do what we can to make a difference. When and if you have the energy and resources to get back to this, please do. You are absolutely correct about the increased throughput. You can reach a lot of people in a lot of different places. You can make a huge difference. Thanks for trying and putting it out there.

People are jumping the gun and think it's safe to go back to their regular life when the numbers show a slightly flattened curve. Even governments are mistakenly thinking this.

Fwiw, after the first couple of times of machining my workholding bolts, I switched over to brass-only bolts, and haven't looked back. Errors happen every once in a while, but brass' softness makes it much more likely that my end mill will be alright. Thanks for sharing.

If you are not failing at least half of the time then you are just not challenging yourself enough. You'll never reach your full potential either.

Thanks for sharing! Your video just gave me the answer to another problem I was having... not because of any particular failure, but I hadn't considered vacuum forming for my project. Until now. Thanks.

Thank you for sharing. There's always something to learn. Looking forward to when you revisit this forming concept.

I'm a cnc mill programmer. The shop I work at does a lot of one off parts in stainless and other heat resistant materials like Inconel, monel, etc... Nailing our 'projects' the first time around is our game... Failure (though a great teacher) can get expensive fast and it doesn't take much

Another great message. Being able to shift to the next project on the ‘rabbit hole’ list is definitely a learned skill. I love how you work. Thanks for all you do!

I really respect you for showing a level of vulnerability that few people do. It highlights for me your genuine desire to help people be better

Great video an it is awesome that you uploaded this video content. It shows even the experts have failures just like most of us. I am new at this and have failures, but I use them as learning moments for future projects. Thanks again for sharing, I do immensely enjoy your content so keep up the great work.

Fascinating. I just had almost the exact same series of issues with a project I was working on. Same machine issues, same homing errors, everything. This has totally helped me get over the frustration I've been having and I'm going to go make some improvements!

Thanks, I appreciate failed attempts as they show the thought process and that is often good for inspiration. keep up the good work! We learn more from our mistakes than our successes.

Mistakes are another word for experience and mistakes are the tuition paid for success. The fact that you have the mental fortitude to do a post mortem on your project speaks volumes about your intellect. I appreciate you sharing, thank you.

I hang my CNC failures on the Wall of Shame in my shop. Not to dwell on the mistakes, but to remind me of the missteps and how to avoid them in the future. Thanks for sharing yours.

bold man. As a maker with plenty of projects where my idea doesn't completely turn out the way that I expected it is nice to see someone of your skill and talent wrestle with failure. Your projects are so detailed and so well thought out that it is easy to assume that you never fail, but of course, we all deal with failure. Thanks for being real and releasing this for us. Much respect.

I totally know what you feel about failure. The disappointment from it sometimes seems very out-of-proportion to the actual failure. Thanks for posting this video. Even though it didn't work out, it made me think about using tools together in a way I didn't before. And who knows, this might work out in the future now that you've overcome the mechanical failures that set you back here.

Ever thought about creating a mold for a mask, but create it using the top of a PET bottle, Heat it up and press it on to form the shape, then, you only need an adapter for the nozzle/screw thread to a suitable filter. Was going to peruse that here, but we are lucky enough to not have been that badly effected.

Awesome video. Thank you for posting. I am experiencing some of this myself...glad I'm not alone with the whole "sprint, then fail, then walk away" process.

The Buck can still be 3D printed, and used as a vacuum form....if you print in ABS the vapor bath for smoothness....

Learning from mistakes is the best way of learning, at least for me. It's the only way I remember it permanently.

I had some of your issues too and learned a lot about the reproducability of homing./zeroing My cnc controller board is susceptable to ground loops and locks up sometimes. When it happens I have to rezero. Sometimes you machine away your reference points. What I do in those cases is use the homing switches, zero the axes, then read the machine coordinates of the zeroed axes and copy/paste them if and when the board locks up. This has saved me so many times. I use a laptop instead of a desktop pc now and the lock ups have never happend again but on important projects I still use this technique.

You continue to inspire, even in your "failures".

I have been down this road many times my friend, the things you learn from the process make your future projects run much smoother.

Great video! You made it further than most of us lurkers have. You made an impact whether your project succeeded or not. Thank you.

I am glad to see I'm not alone in suffering failures with fusion and my CNC machine. Thank you for sharing excellent work. Better luck next time.

The vacu-forming concept is excellent - 3D printers are being used en-mass to fill the gap until injection molding can ramp up for this PPE, but vacu-forming is a great intermediate step. Thanks for sharing your frustrations - these hobby-class machines (includes almost ALL 3D printers) are fantastic, but they aren't super rugged, and seeing the kinds of flaws different failure modes can create is helpful to everybody in diagnosing problems. The runner wheels on your CNC machine, for instance, are almost exactly how most delta-arm 3D printers work, and a similar shift in a printer would result.

This is the first video i have seen on your channel and you knocked it out of the part. Liked and subscribed. Can't wait to see more from you.

Posting before finishing the video -- I wanted to add...we have a vacuum former at our makerspace and it is a fickle bitch. One big thing I've learned using it is when possible...use a negative form instead of a positive buck. The positive shapes almost always have folds around the peripherals where joints don't pull smoothly. As the vacuum pulls, the majority of the material is eaten up by the form leaving little for the void, resulting in stretching.. The justification for suggesting negative space is - look at the solo cup. As the material draws into the void it experiences the same forces on all sides, leaving the majority of the material to comply in all directions outwards. Addendum after finishing the video. Thanks for sharing and trying to do your part. It definitely can be frustrating when every part of a project goes sideways. when the machine that makes the machine breaks it it hard to not 'blame your tools' but in this case it's worth the mental credits. Enjoy that sun!

good man Winston.. there is no failure when knowledge and experience have been gathered 👍👍

Small point really, but the holes on the wrong side could be fixed with what we in Australia call Builder's Bog - probably Bondo in the US. I have saved numbers of projects where I have removed material I shouldn't have, with the judicious application of Bondo. I'm not sure about how secure it would be to apply Bondo the outside of your model and then re machine it - maybe roughening the surface so it could "key in". I make a lot of mistakes and an advantage of that is learning techniques of how to rescue disasters.

Always enjoy your content and appreciate your honesty.

Great to see the process - and I echo that the opportunity has not passed (you may not want to hear that :)) - I think it is a great idea to vacuum form. This has shown that 3D printers are an amazing tool - but that they may not always be the 'production' tool unless you have volume (a farm) - despite having 3 printers I have used the laser cutter for shields and it can churn out 100 a day as pooped to 5. The meds have also commented on how easy they are to clean overnight. So I love the different path, and they were mistakes we all make (I just recessed bolts on the wrong side of a frame for a deck chair - who does that!)). Keep doing what you are doing!!

You counter bored your holes on the wrong side. I appreciate knowing that someone I admire makes the same stupid mistakes that I do!

Good on you for all points made!

Thanks for sharing your mistakes. It's important to be OK with failure and encouraging people to experience that and still move forward means quite a bit in today's atmosphere. Thank you.

Hi Winston, i am from germany where we also had the same idea like you, we are working still on a mold, but we 3D printed the mold out of ABS instead to mill it. Currently we dont have any possibility to get on a vacuum forming machine, because the machine is in a university and, you guess it, closed. I hope you can go further with this project, because this is exactly the aproach where we was thinking this would be possible to cover the most neads for masks. Please keep us up to date. We would be so happy. Best greetings from germany and please stay healty aswell your family and friends also. Michael

You should continue. Like other people said it isnt going away soon and this is a great idea.

Great video! Thank you! We are all in the failure boat most of the time. I really learned a lot from your video...

What you accomplish with the shapeoko is astonishing. Good enough is good enough when lives are on the line. Hit that shift with a Dremel and vacuum form to your hearts content.

Awesome video great to see potential problems that I may see when I get my machine. Glad to learn about but positioning of the bit a zeroing. 🎨🤙🏼🎣 thanks for the info.

Thanks Winston! Stay well, see you in your next vid!

You were so close! Keep going!

Awesome video. Takes courage to show the "failures." We all learn from it. Mahalo for sharing! : )

Great video, I teach high school woodshop and CNC and learned a ton from this video. Thank you

Ironic you should post a video about failure and projects as I just put together an aquarium yesterday and it seems like I’ll be doing it again today. C’est la vie. Stay safe bud!

Great video Winston! =)

It happens to us all..... Good idea with the vacuum forming though! 8 have been meaning to make a vacuum forming set up for a while....

Failure is the BEST way to LEARN. Don't ever give up, just try something else. Everyone FAILS more than they succeed, but it's those that keep trying and eventually succeed that change the world. It is the success that defines us, and how we pick ourselves back up for the next attempt, it is NOT the failure that defines us rather it is the failures that we learn from which is what makes people successful!!!

use some bondo or wood filler and sand it into shape. it's a vacuum form, it doesnt have to be perfect, just has to work.

Seems like a great concept that just went wrong because of the machine being slightly broken? The go-cart thing - reminded me vaguely of Richard Feynman's critique of the top-down design of the Space Shuttle's main engines which had similar issues - well worth a read!

Winston, I was against you shelving the project until you made mention of doing so for your own mental health. Exercising self-care is an important aspect of good self-leadership. So, good for you. It seems you took away other valuable lessons from your so-called "failure", and that's a good thing. I, for one, don't view your attempt at machining a buck to thermoform respirators a failure at all! Aside from the homing/zeroing error, the ball screw and v-wheel fracture that led to the mis-machinging were both out of your control. So, once you're back in a good head space, get back in the garage, repair that CNC and get back to the brilliant work of which you're so capable! Thanks for the incredible view of the rainbow at the end! Be well and do good work!

Winston, part of learning is making mistake, what I love about these video is what issues you have found. Such as the machine had issues, that is the problem I found with my CNC machine. Typically you think your machine is working in perfect order and find why it did not come out. You are very proficient in fusion 360. The second wave will be something that will cause more PPE to be available for our first responders. So I would not give up on this mold.

It takes a lot of courage to admit to have failed at something. The world shows only the successful stories leaving those who have failed behind. Heads up, because one knowing where he has failed, will learn from that, thus improving his skills.

2:50 You scored 100% for Darth Vader look-a-like face mask!

It's a pity it failed. Would've love to see a finished product!

I have one of these days at least once per month, sometimes it's once a week. I appreciate the reality, we present ourselves as perfect and everyone makes many mistakes - daily.

Thanks for sharing.... and carry it on! 👍

Yep I saw the rainbow too. Light at the end of the tunnel. We will make it through this!

It is the most necessary trial in this period and I wait for the next.

I had the same idea about a month ago and while I completed my buck the lack of material on hand locally and the geometry I was forming got the better of me. I had wrinkling because I was using kydex(on hand) and the buck wasn't ideal. I realized at least for myself a bunch of folks without the ability to vac form but having functional printers were able to produce faster than I could on the vac table. So I walked away as well. I continued designing and revising the printed version but I haven't been back to the vac formed one.

You did not fail. You just worked out the bugs. It takes me about 3 tries to get things perfect. Take a break and then get back at it and you will see all is good.

Works great! Do it all the time in film industry and rapid prototyping. Try using a very high density carving foam instead of mdf. Easier to finish by sanding and poly primer. Or you could print one with the same concept of having flanges for a return edge, finish with high build primer and mold that.

@Winston Moy, Love your videos, can you please explain how you are using different size of end mills and drill bits with makita router, makita has a 1/4 collet right? is there other sizes of collets for makita router. Thanks

Good information.

Thanks for the video. I learned a lot from it

you are so lucky to have sunlight. we had snow today!! :(

Hello, I will dig up the topic a bit, very interesting material, I have a question, what material did you mill it in? and I was curious about the method of finishing milling, where did you mill the top and bottom with what kind of milling cutter? and would it be possible to share this file, because soon I will have several complicated forms for milling, this method seemed very interesting to me and I would like to get to know it better :)

Create a return lip at the bottom of the form. Will make the edge smoother, and you can punch holes into it for the mask straps. We just printed and sanded our tool. Works great. We print thermoform tooling all of the time at work for short run parts. Just have to monitor your tool for heat soak if you throw it into a production machine. Picture of our first prototype: Montana thermoform imgur.com/a/Gtuz6iK

Brilliant Idea! I would love to see you attack this again. Your router skills are far greater than mine. However, I'm going to try as well. My wife is a nurse. Everyday I hear horror stories of having to reuse PPE because replacements just aren't available.

Your successfull rate is pretty good. I made so much prototype for whatever I make that I do not even count the first attempts...are all pre-produciton models :-)

As a perfectionist myself I hate failures sincerely. Sometimes they happen. But giving up is never an option!

In aviation, pilots do a walk-around to check the critical parts and functions of the plane. Perhaps this could be used for all tools.

Ouch I had the same problem with HDZ upgrade today... My bearing holder at bottom was loose and screws on the HDZ linear rails unscrewed and popped out on both sides. It freaked me out when I heard a crash when gantry moved up to switch cutters. I really hope HDZ won't give me problems now :(. Side note though, the HDZ is really awesome and a great upgrade! Just add lock tight if you get one.

Yea, it's always good to "trust, but verify" that everything's been tightened down. Set screws are the most common thing that need to be double checked.

Hello Winston, I'm a tool and die maker at a food container company (Genpak) we use thermoforming to make our product. You sparked my imagination of using the process to make your design. When we are prototyping a new design it's time from concept to product in hand could be a time problem. Any way if I could help you in any way please ask. Like your narration while watching your video.

I'm in the same boat! Almost identical. Want to make a vacuum mold but my 3018 mill just sucks!

While I don't wish failure on people. I like seeing this. Failure is the fastest teaching tool for many people.

When every failure probabilities aligned

How about cutting with indexing holes, where you can put dowels later and stack them. You might need to sand it later anyway. Or just 3D print it. :D

Man, CNC CAM it's still hard to do. Way harder than 3d printing. But... You can make to mould for vaccum forming in a normal 3d printer. I don't think it will melt.

Failure is (almost) always an option. Often a good one. Cant learn much if you always succeed at some level.

Thanks for sharing Winston. As the others below have commented, when we learn from our mistakes, they become as valuable as when everything works perfectly. What sort of cover do you have over your router top? Also, how have you installed the blower, where did you get it, etc.? thanks

It's just a regular sock I cut a slit in,to get around the power cord. Then I used a strip of velcro to close it up again. It's mainly to keep aluminum chips out, don't need it for wood or plastic. Meant to catch big particles, not filter dust. The latter would restrict airflow too much.

comments below or above depends on how you think about yourself

Regarding the counterbores in the wrong side... plugs glued in would repair that easily... Plastic wheels should be replaced with brass at least... for longevity (do u have a small lathe ?)... and really... machine-maintenance is something you should be doing on a scheduled basis... as a production engineer, I have learned over the years that prevention is paramount... ALL manufacturers have maintenance-schedules , they can't afford unscheduled downtime in the middle of a run. 🙄 Not beating ya up here, just making some suggestions. Good luck !! 🙄🙂 😎👍☘🍺

Failure is important. My friend 3d printed one of those masks and it was pretty crappy. I like your idea to vacuum form, but the process of creating the buck was way more complicated than it needed to be. That profile could be sculpted out of a piece of wood with an angle grinder and a flap disk.

I have in my head another idea.. Injection silicone and making "mold form from 3D printed part.. However curing is too long and I dont know if it is worth to make it done.. I have only basic model in Fusion

Enjoy the video thanks for sharing have a blessed day.

Maybe you didn't show it well, but I'm at a bit of a loss as to why you gave up. Your finished positive is slightly imperfect from your mistakes, sure, but a little sanding paper and you can have a decent chance of vacuum forming from it without issue. A vacuum forming rig from Shapeoko would be a great product!
