Side effects of social distancing = more scrappy 🤠
Mike Patey sounds like the best side effect.
Oh snappppp.... I got the virus....already having side affects...bummer....👍👍👍
Optimism @ it's finest
Mike, you asked about fewer longer vs more shorter videos; More videos please, and if shorter it's all good! Thanks.
Got lemons, make lemonade. Thanks for doing all the work so we can watch along.
Stay safe I don’t know what I’d do without positive videos like this to distract from all the negative going on.🤙
Glad you're not Scrappy Distancing.
LOL good comment!
So funny /s
Hi Mike, I might have some tips and tricks to save some time when it comes to making carbon parts: compressed air works great to demould parts. Instead of filling the backside of the mould and vacuuming it to a flat surface you can just put the mould in a "complete" bag (like food in a ziploc bag), as long as plastic bag is not under tension it gets pressed onto the mould evenly and the mould doesn't bend. Also I find mould release agents like Frekote 770NC quite a lot faster than wax.
I work in a small german company that makes prepreg autoclave carbon parts (manly for racecars: LMP, DTM, GT3s), so if you somehow end up in southern germany and interested I can give you a tour, just contact me. And of course if you ever need some carbon parts, we can make them for you ;)
Do you do courses? I would love to learn how to make carbon parts for the plane I am building
I'm 15 and this is my favorite TH-cam channel
Never been on an airplane👍👍👍
Huh, im not the only one my age with this passion... Your missing out bro.
Look into civil air patrol if you live in the states.
You definitely gotta give flying a try. It's truly something special, and for me is my ultimate "escape" from the worries that take place on the ground. If your in the states, and after the whole COVID-19 pandemic boils over, you should go to an aviation event or airshow that offers Young Eagle flights, which are free introductory flights for kids/teens ages 12-17. Idk if they still do this, but when I did my Young Eagle flight a few years ago, they also gave me a free account for Sporty's Learn to Fly Online Course, which is INCREDIBLY helpful in teaching you everything you need to know on learning to fly and getting into aviation, and prepare for either a Sport, Recreation, or Private Pilot License. If you haven't already, and have a decent PC or laptop, I also highly recommend you get a flight sim, especially FSX:SE since it runs good on older systems and is very cheap ($24) on Steam. For joysticks you can find a new Logitech/Saitek Extreme 3D Pro at Best Buy or Amazon for around $30-$40. A flight sim really helps in keeping your passion for aviation alive.
@W C I'm not talking about Ace Combat, H.A.W.X., or some other arcade flight game, I'm talking a legit flight sim with more accurate physics, flight models, and systems replication such as FSX, X-Plane, P3D, etc... I'm not saying online courses or flight sims should replace going and actually taking flight lessons if you intend on flying for real, but they *_do_* teach or at least give you an idea or understanding of aviation concepts and how it all works. For me, I always saw FSX as a tool to prep me for real world flying, to give me a better understanding when I go into ground school or flight lessons. FSX is where I learned how to fly an airplane and what all the controls do and the forces involved with control flight, basic piston engine management, different forms of navigation, how ATC works, etc... I've also flown with a friend before in his plane on multiple occasions, and got to take the controls a couple of times as well, and everything I learned from FSX and my online course applied to real world flying as well. The only things FSX or flight sims in general differ from real-world flying is radio communications, the level of detail & accuracy with the environment, and the biggest of them all, the physical feeling & forces that are missing in a flight sim that you experience in a real aircraft. Other than that, majority of the concepts you learn in FSX or an online course still apply to real flying as well.
This dude is my hero. This is what I would be doing if I had the money, and the brains, and the knowledge, and the energy.
I'd be happy just to have his work ethic. Wears me out just watching him.
Yeah.... I don't think I have anywhere as much of any of those....
@@--_DJ_-- I was just thinking about that. When this series is over he's going to have an awesome plane and I'm going to have a hole in my TH-cam playlist.
@@jcims That is the beauty of this channel and this man, he never seems to be done, even when it is flying perfection.
Master of carbon
I've done quite a bit of fiberglass and epoxy work at the family boat shop and built different molds over the years and kept telling my brother to get a vacuum pump and start using epoxy and carbon fiber instead of this nasty Polyester for some of the parts. Your attention to detail and perfection is a must and it shows in everything you put your mind to. Not to often do I see guys doing the level of craftsmanship you are capable of!
It’s one thing to have the money...but the attention to detail, the finesse, the desire for perfection,...all things money can’t buy.
I know it's not cool to be envious - but dam...My dad was a fighter pilot in the USMC and was KIA during Vietnam and it really sucked growing up without his direct input on my life. All I had was an imaginary hero. No one to correct me when I was wrong - to encourage me when I was right. I tried to be a pilot when younger - I solo'd at 6 hours, but I had not one ounce of 'business sense,' and I had no idea how to proceed on my own. My mother had turned into a raging alcoholic and then I see someone like you and your brother (oh yeah..I have three older brothers and we're all so dysfunctional and un-trusting...) and I see how successful and happy you all are. Again, it's not cool to envy, but I can say it's awesome that you and your family have been so blessed. I'm grateful I can at least enjoy watching your success. Wow. Can I get off this couch now? lol.
Two hours later... nice script and continuity. Great how to on plane fab. Thanks Mike. Well done. I learned quite a bit.
Really like watching you make carbon parts, I used to work in a composite shop a buddy started, nobody taught us to do it we just figured it out over time. These videos take me back to those days. You makeshift oven is great, we had a small autoclave but for big parts we had a box built out of 2 inch thick foam taped together had a cutout on one end to blow a heat gun into and a flap on the other to regulate the temp. We made some awesome parts with that primitive setup. That male, or copy of your original part is called the plug, after getting it perfect and mold releasing it we always painted on several layers of gel coat before backing it up with fiberglass for structure. Helped prevent air pockets, was easy to repair later and could be wet sanded and polished to a mirror. Sorry for being long winded but you got me reminiscing 🤔
@mike patey could you do a video showing the calculations you do when youre figuring out airflow, volume, lift coefficient, forces acting on fuselages etc before you get hands on with a part ? Cannot get enough of these videos, definitely one of the big positives in the current world situation that youre getting "back to work" on scrappy more. Keep up the great work and stay safe.
I am again reminded why my carbon fibre furio is still unbuilt in the hangar after 8 years. The time , cost , skill set , tool chain , experience , enthusiasm and persistence is way way more than I imagined when buying a kit advertised as 1500 hour build time - yeh right . I’d have to retire , have at least $ 200,000 lying around and then hire a team of 4 people with the experience in each discipline - perhaps that is why so few kits are completed . Mike you are really unique and keep the videos coming . Big thanks
My social distancing today was spring cleaning the garage. Tomorrow I'll put all the cars on summer tires and do some maintenance. Happy to relax and watch this new episode.
I so enjoy watching your project come together. Thanks for taking the extra time to film it so we can hang out in the shop with you. Thanks Mike.
Thank you! I totally forgot about the problems of the world for 25 solid minutes. Thank you so much!
Hello Mike, I love seeing your progress on the build, I'm not familiar with carbine fibre but you make it look easy. I met you at Rock the Ramp last summer and told you that I'm building my own airstrip and getting back into flying. By the end of this summer I think it will be complete and while I can't start-in yet this spring, I've decided on what I'm going to build. The weather here is pretty crappie yet and I have a set of plans for a Hummel Ultracruiser, which is actually considered 103. I'm building the forms as we speak and have a bunch of aluminum stock on hand so while the weather is not cooperative for digging, I can be building. I really pray that this virus doesn't mess-up Oshkosh this year and would really enjoy meeting-up with the Cowboys this summer again, really enjoyed it and seeing everyone so supportive and excited over aviation and fellowship. Thank You, Chuck
The quality of the videos don't bother me, it's a great trade off for getting them more frequently I'm so addicted to this channel. The content of the videos are amazing and I think it's awesome that you're so willing to share your build with us in this raw format - no bullshit! I hope you'll continue to make planes and share the builds forever. I can't wait for the next episode!!!
So happy to see that big smile back on your face. I think it's because you can see the end of the build now. It's going be an incredible piece of aviation art when you're done. Picasso Patey👍
I’m watching this after listening to a 3hr jocko podcast; between Jocko and Echo’s get after it mindset and then you compound it with Mikes attention to detail, engineering, and drive to get it done. I’m sitting here ready to get home and get back to work. This content is much appreciated!
I was planning on taking a 1 year course in composites.That has been delayed.I have watched all your videos on your channel (over the years)and already learned a ton of tricks of the trade.Thanks for being my post apocalyptic online course teacher while we are locked down.
Let me tell you a story.
I used to own/use a British piece of equipment called a "Dome Press". The press had an interior surface of 48 x 96 inches. It was an 8' half cylinder of 1/2" steel with ends welded on of same thickness. A 3/4" x 2 1/2" frame was welded to the cylinder to provide attaching points for rollers in a U frame every 18"s. The dome had 1 1/4" air inlet and exhaust with 1 1/4" ball valves on each. Pneumatic cylinders, one on each end centered on dome ends provided lift to an attachment tap welded near top of dome. The lower frame supported a tray 8" deep the same dimensions of the top. In the tray was a perforated platten which was connected to a huge vacuum pump. The lower frame supported the pneumatic pistons which raised and lowered the dome as well as supporting all the pneumatic cam clamp cylinders & dogs. The top "dome" carried strip heaters and a 5/16" 3 ply rubber blanket suspended over the 4 X 8 ft opening.
Work was placed on curved or molded forms on the bottom platen, the dome was lowered and clamped into place via the pneumatics, the vacuum was turned on as the dome was pressurized to 35 psi. A 50 hp Ingersoll Rand compressor supplied the air to the dome from a 450 gallon tank operating at 125 psi. Interior temp of the dome was 130 degrees.
We were manufacturing our own complex shaped plywood which was then burl veneered for automotive and aircraft applications. We were contacted by Rolls Royce and Metal Crafters to fabricate 12 dashboards for a customer financed "Sport Car". Rolls assured the customer that he would own these only Rolls Royce models and then they released same car as a Bentley for production. Ouch!
Carry on your fine workmanship and engineering.
I am a simple man, I see that Mike Patey has a new video, I click and watch.
My boys (3 & 4 yr olds) and I LOVE your channel. Thanks for keeping it clean so I don’t have to worry about them watching alone. They ask me every night if “scrappy has a new video”! Also, thanks for all you do for general aviation.
17:30 that making extra parts with the (planned) off cuts is brilliant.
There is no social distancing with Scrapy the work must go on there are a lot of people waiting for your videos.
I can relate to the time penalty. As a novice to fiberglass, I committed to making a custom air filter tray for the snorkel of my RV-8 along with a new intake and flanges for intake and snorkel. No vacuum bagging; not worried about appearance; just make it functional. Fabricate, modify, refab, smooth, fix, etc. Finally finished components that will work together, and assembled them. Total time invested: 115 hours. Wow.
LOOOOOOOOOOOOVE IT!!!
we need you to set up a live cam so we can 24/7 it. . LOL
Now, when it comes to shop hours /$ per hour, I think there's gotta be a comparison with real world rates V Patey rates. Mike does twice/three time the amount of production on his hour. Love seeing the steps involved here in Build it, botch it, fix it & learn. For what was possibly an easy looking part to produce and there were easy ways out, you really drove home the level of perfection you chase Mike. Wish there was more of it out there in the world.
don't normally add comments but Mike you are an inspiration!!! i love all aircraft especially older craft pre 1960's but what draws me to your channel is the engineering side of things that we get to see only through you, truly gifted engineer!! love your work ethic ( i bet your wife misses you at times ) LO L keep up the fantastic content. Life long viewer and Fan
Watching this guy always makes me want to go and DO stuff, build stuff, invent, create. Inspirational!
Neat seeing the cost analysis for these, I had always been curious of that aspect. Thanks Mike!
I’m so glad to see you’re using Kaiser aluminum, keep it American! Being a millwright for 25 years for Kaiser Aluminum here in Spokane it always warms my heart to see our products on you tube channels. Thank you!!
Randy Walker #spokanedoesn’tsuck
Your content is awesome Mike. For me personally I don't care how long the video is, just like seeing the beginning an end of something is a single video. Great work Mike, your inspiring.
I've never met you but Mike, your are one awesome dude. Thank you for being you and sharing your knowledge and positive/hard working values with us. Your truly a value to the community. Keep it up.
Multiple scrappy videos in one week? SCORE!!!
You're videos are filled with joy, passion and positivity!!!. It is amazing to get a fraction of your excitement in such hard times! Props to admitting your mistakes and explaining how to avoid them. Thank you Mike Patey.
lol, props, geddit
@@roryblake3232 that was not intentional!
Cant wait to see scrappy completed .These educational videos are my fix for the day.
Makes you appreciate the work that goes into making Konigsegg wheels!
I’ve been re-watching all these while “social distancing”. Quality YT videos make life easier so thank you.
Stay safe, back to work! 💪👍
I could watch your videos all day, not a great thing because I should be studying for Aerodynamics and Turbine's tests!
Love your Sponge Bob time breaks, awesome...
Love your thought process, mistakes, corrections, pure art, pure science, pure engineering brilliance..
Really like how you showed the price difference and comparison. Can’t wait to see scrappy fly!
Just love what you are doing.......not about cost, but pushing the envelope
Unbelievable passion and a building package of aviation equals experience. That magic word created by time v trial v error. Wow I'm exhausted.
The plug rules and the front and back match are just right! Love your methods!
For anyone who knows a thing about fluids, it LOOKS good the way it’s going on. I love it!
Mike great series on scrappy. your enthusiasm for using CF is great , but maybe others that follow you would like a video on the finer points on using CF like the type of resins, weight and weave of cloth, and what you use for peel-ply . Back to work.
Great shop. I always suggest a separate room for dusty tasks, put your wood shop tools, a downdraft table, hanging dust collector all together in a room with french doors to get in and out. This cuts down on so much unnecessary dust buildup in the rest of the shop it's amazing.
After watching your videos I fall back onto my recliner exhausted. Way to much energy. 🙂
Sometimes Mike Patey shows us a time-lapse, but it’s hard to tell.
😂
Yeah I’m definitely loving the shorter but closer together videos
You just made my day, thanks Mike!
Tips for splashing molds. The positive plug was good, using a sandable primer like duracoat or a gel coat to give an even color will help reveal imperfections, but it looks like you made it work.
For the splash again a gel coat first will make the surface much smoother. Buy the unwaxed gel coat and the surface won't cure when exposed to oxygen allowing a good bond to the rest of the splash. Then use a layer of glass veil to build up behind the tool surface and help with pinholing. Then a layer of glass fabric +-45, 0/90, Matt glass to build up thickness, 0/90, +-45. Now here is the secret. If it's a room temp mold it doesn't need to be carbon and it doesn't need to be vacuum bagged, if it's elevated cure mold use vinylester resin, carbon fabric after the veil and post cure to at least cure temp of the prepreg it should be ok for 250f resin systems at 230f soak for a few hours longer at soak temp.
These are guidelines please do your own tests for structural parts everybody.
For room temp molds though unwaxed gel coat a layer of glass veil then fabric then mat and no vacuum bag will produce a much cleaner tool surface than trying to get carbon fabric with no pinholes in tight curves and a vacuum bag, that stuff doesn't like to wet out like glass does. The gel coat will help identify any weave printing as well once the splash is demolded. For the materials, any boatyard supplier should have them.
The drive the hard work the flawless perfection absolute untouchable notch of knowledge...mike patey your an amazing human being..some day just to shake your hand would be an amazing day...👍
Mike you are the Telsa Of Aircraft. You are amazing Aircraft builder for sure. Outstanding!!
If you look up the word “persistence” in a good dictionary you’ll see a picture of Mike Patey. Another great video.
Awesome video showing the process to make custom carbon fiber parts. I know it’s a time very consuming process which makes the parts expensive but never realized the materials themselves were that expensive. Awesome and educational video as always!
Thanks mate very useful molding lesson. Glad to see more scrappy
Mike, that was truly one of your best videos. Super instructional, step by step, loved it.
mike patey you are the definition of knowledge and know how holy heck man! Phenomenal videos of the Scrappy build
Great video Mike 👏
This is the sort of content that will attract young people to our industry who have the right stuff 👍 ... those with a desire for perfection and a willingness to stick with it until it not only is done, but is done right 😉
Really appreciate your tremendous effort In bringing us all of this insight. Our thanks also to the team behind the scenes. I’m sure they’re playing a very important role in helping you produce such quality viewing for your followers.
Looking forward to seeing and enjoying more 😎
Mike, Cool Vid. I never get tired of You making the carbon fiber parts for Scrappy.
I did not mind the lengthy vids but the shorter (like this one) are Excellent. You should
present it as You like. I happy no matter how or how long, I usually learn a good bit from
each video, Thanks Man.............
this guy is the most fascinating guy in aviation currently.
Just Plane Silly , your completely online biannual flight review for life certificate course, I'd say, is even more interesting, especially given the current circumstances ;-)
Payment is in prepaid and gift cards, right? 😉
Happy flying!
Stunning work, Mike!
Thanks for all the videos Mike (and crew)!!
Absolutely Amazing job!
I love the details and commentary. Thanks!
Excellent vid Mike thanks for sharing!
Awesome, AS ALWAYS! Thanks, Mike! Be blessed!
Ding! There's the update.
From what mods I'm seeing (vs. my lack of knowledge of how much carbon is in a Carbon Cub), you're making a true Carbon Cub. Love the updates! Thanks for sharing!
Wow you are truly amazing craftsman in everything you do.Love watching your builds. For the fist pumps, less is more please.
Thanks for two videos in a week. I love em!
Good work Mike, nice fabricating!
I rarely have time to watch an hour video so yes I’d love to see 15-30 minute videos. We love you guys! Thanks for taking the time enrich our lives!
Beautiful job Mike!!! 💙
Thanks for adding the weight and cost comparison. The benefits seem worth it to me.
I can’t wait to see this plane fly, Thanks for the virtual ride Mike❤️
We'll need men like you to rebuild the world when the crisis is over. This comes from an intensive care resident that lives in Paris, France (and a pilot). Keep up the good work your channel is a blast!
Thank you for sharing the cost difference and comparison on Al vs Carbon. I’m slowly catching up on your scrappy build. Already planning on AirVenture 2023. See ya on the next one.
Always educational and entertaining. Thanks!
Keep it up Mike! I love all the videos and if these shorter ones are easier I’m on board, nothing more exciting is a man with a plan that wants to share with everyone!! Your an inspiration to all who are lucky enough to view
What a worker!! An example to all of us.
That was so awesome Mr. Patey
Love your videos, and knowledge, I hope you never stop posting videos! You really inspire me to work more and try new things on my projects. Thanks for the entertainment!!
You brightened my week significantly. Thanks for another great video!
Great video, as ever!
Have a look at the stuff called Epopast for making the negative moulds. It's a fibre-filled, two-component almost clay-like substance that you can make half-inch thick moulds with. You wax your positive plug with release agent, then apply a thick layer of (hybrid) gel coat and while still sticky, mix up a batch of Epopast and clay it over the gelcoated plug.
Once dry, it is incredibly stiff, has near zero shrinkage, is as smooth as your plug was, so no need for more wet sending. Works extremely well and is certainly less work than your current method (which I am sure will appeal to you ;-) )
Now back to work!
Great video Mike stay Healthy
Absolutely love the make do efforts and attitude. ❤️ heat box!
It totally makes my day watching you make parts awesome
love the new video format, even one video or so per week is fantastic
Love each and EVERY video!!!! Thank you Mike!!!!!
Honestly your videos and craftsmanship are amazing. I can't wait for your videos to be uploaded. 🤙
Ingenious engineering, that's all I can say!!! Looking forward to the next episode!
Thank you for all the details you share, one of the ultimate channel to follow for every engineering Friendly Guy. Positivity and motivation seem to animate your person. Awesome!!!
Outstanding craftsmanship and attention to detail Mr. Patey.
Totally Awesome. I'm starting to experiment with composite layup in my garage thanks to these videos.
Your videos sparked an aviation flame inside of me I couldn’t put out! I’m taking my written test tomorrow and hopefully I’ll be sharing the skies with you soon!
Seeing another scrappy video so close to the last one, totally made my week! Thank you for this insanely positive uplift during such times.
So enthusiastic Sir...................love that style !
