Amazing! Thank you so much for sharing. Great length, music, narrattion, etc.
Thanks Nick👍
Don't forget to wear a dust mask when you sand that foam!
Great job!
Looking good
Great job and thank you for paving the way for a easy to understand method for cowl building! The reson we homebuilders lack understanding of traditional methods for designing is bc not many will show their process, in fear of being critisized! It takes care for the hobby and courage to know there will always be haters! Great job my friend and thank you for helping my build continue!
Thanks for the kind words sir! I’ve had to come to terms with the criticism over the years. It’s just part of it when you publicize a build like this.. All things considered, I’m happy with how my cowl turned out and i feel like most guys out there can get similar results. Thanks for watching!
Great video
Thanks Pat!
The cowling plug is turning out great!
Thanks guys👍
That looks great. I love that scoop.
Thanks Doc👍
Great how to video! Shape looks great!
Thanks!
Awesome tutorial! I will be doing this myself one of these days and will refer back to your videos.
Thanks Mike👍
ever try using a foam wire "knife"? Can be very useful in bulk convex cuts (I make mine out of conduit and a wood backbone - string some safety wire (or nichrome wire if you have) - and hook to a battery charger - or train transformer). Also - since you are a fan of gorilla glue (like who isn't!) - mix it with some vinyl spackle (1part GG to 10 part spackle) - and you will get expanding foam!!! Great for those finish dimples - and quite sandable and shapeable!. Great looking cowl!!!
I have never tried a hot knife before but I can imagine it would be a useful tool! Thanks for the tips👍
Good stuff. You made look doable. Enjoyed.
Thanks!
This is how i was thinkin i would make my cowl for my affordaplane build. Ive been at it for a couple years in my free time which isnt much. But watching this really made me more confident in doing it myself. Good work man.
Thanks man! Get on it and keep us posted👍
looking forward to your next cowling video. Hope you shoot some video of the fiberglass process.
Good Morning, Josh. Thank you for posting this. I'm building a Rans S20 and have several modifications to make on the bottom cowling. Your tutorial was very helpful!
If you can make two sets of cowlings you can or will have a use for them believe me don't let all your hard work go for only one cowling. Great job 👏
Thanks Keith👍
Looking great! What a time consuming, labour of love!😉
You have done a magnificent job with that....Its a good way of doing it too. But no matter which way you do it it will always take a huge amount of time. Another top 10 video Josh
Thanks Mark! Always enjoy hearing from you sir👍
Your work inspires me Josh, keep it coming. I'll be doing the same (some day!!) and will look to your well documented videos for guidance!
Thanks!
Really should be wearing a little PPE...at least a face mask. I want you to be flying this beautiful machine for a long time into the future!!!
nice job!!
Brother you seriously impress me
😎🎩♠️
Appreciate it & thanks for watching!
Magic stuff that foam! Project is looking real good, I subscribed.
Thanks!
Thank you sir. I had no idea how I would do my Murphy rebel Cowell thank you again
Beautiful work as usual, love it!
Thanks Keith👍
On the left side about 23.6" back I see a high spot. 😉
Lol.. noted
Awesome work here Josh.
I’m pretty sure your scoop intake is much larger than you need and will create more drag than necessary.
The inlet should be smaller than the outlet
I hear ya, I’m feeding the coolant radiator, intercooler, oil cooler and air intake all from this one scoop. Forced induction makes a lot of heat and the exit part of this cowl will be addressed later in the series👍 Thanks for watching and commenting! It’s a bit of an experiment so we shall see what happens when we get to testing it…
Good job
Thanks!
I bet you're wishing you masked off the rest of the plane to keep the dust out (and maybe the workshop too!).
Cowl shape is looking pretty good so far 👍
Would have saved me some clean up time for sure! Live and learn right?
look at project kitfox utube channel. he made his cowl same way you are with foam. might get some pointers
I watched his series. Great stuff!
Your off to a great start on the cowl Josh. I can see people wanting a firewall forward kit from you in the future. Especially once you have tested and worked out any bugs that might come up. It is sure going to look awesome when you get the cowl finished. Are you going to make this a mold to pull other cowls from?
I don’t plan to make a production style mold from this. It’s got some proving to do as far as airflows and such are concerned. Maybe later if it works out and the Yamaha proves to perform and last. Thanks for watching sir👍
No PPE? Are you nuts?
How long did it take you to get the expanding foam off your hands hahah! I get that stuff all over me when I use it, Its like anti seize haha! Great work, just found your channel. Really enjoying your videos. Keep up the good work!
It’s sticky stuff. Acetone takes it off pretty quick👍
So unique in so many ways. Nice! I know you're engine is liquid-cooled, will the inlet scoop allow enough air for both the radiator and turbocharger, or will have to add an intake?
The intake is sized to supply air for the radiator, intercooler, oil cooler and intake. (Hopefully).. lol it’s a bit like playing pin the tail on the donkey or black magic. More to come on all the ductwork inside the lower cowl to get it all to flow like I have planned. I’ve done all the reading I can do, took a somewhat educated guess and we shall see if it pans out. If not, I can do version 2 right🤷🏻♂️. That’s what “experimental” is all about in the end I suppose…
How many hours do you think you have in your cowl?
Way to many, that's for sure.. Its tough to gauge something like this when its my first time to do it on that scale. Id say 150 -200 hours on this one. Like all projects, there are things id try differently if i did it over again but i am super pleased with the result.
What’s in the spray bottle?
Just water.. humidity sets off the gorilla glue
