I really like to option that you give us to see the process, for those of us interested in what and how you are doing it, it is very appreciated. Very good work done on the cowl and on the video, it was very nice to watch
I’m currently in the process of modifying fiberglass cowlings to fit an engine upgrade from Jabiru 4-cylinder to the new 6-cylinder Gen-4. It’s not easy, although it seems to be for you. I have spent days laying up cloth, only to cut it all back off and start over because something wasn’t right. IMO your composite design and fabrication work are very good. Thanks again for sharing your methods.
I’m with ya man, this hasn’t been an “easy” undertaking be any stretch. What progress you see in the video is a little over 3 weeks of time, granted I can only work a few days a week on it. Thanks for watching and commenting sir👍
Two things I saw which may make your life easier. 1. Put a soft cushion (old pillow or something similar) under the cowl when you're working on it and that will support it and stop it moving around so much when you are doing your layup on it. 2. Use Peel Ply on all your layups - that way you won't have to do any sanding afterwards. It also has the added benefit of wicking away any excess resin giving a lighter layup. Great work and innovation otherwise - keep at it!
Thanks for the tips! I’ve been trying to incorporate more peel ply usage but find it difficult to get it to conform to anything other than a flat surface. Maybe it’s just the kind I have so I’ll have to look for other versions.
@@Project2Aero With Peel Ply you can cut it on the 45 so it conforms better and also use multiple smaller pieces overlapping rather than one large piece.
If I can benefit from your experience on this, how many layers of cloth would you say is necessary to lay up on the plug, before the uncut cowl-set can be removed? I have 2 layers of 5~6 ounce CF built and would like to mount it on a rotating jig/stand if possible. How many layers (average) thickness did you decide to stay with before adding the hexagonal stiffeners. I have watched this whole cowl build series at least 6 times, while doing my own. Thanks brother 😎🎩♠️
Thanks for following along! This is a bit of a loaded question that really depends on lots of different variables but for me, I found that 4 layers of 6oz 2x2 twill was sufficient prior to adding the interior structure. I think at only 2 layers, you’d run the risk of it not holding its shape on its own well enough to hold its shape off the mold , especially after being split in half. If you’ve got more compound shapes than I have you could get away with less I’m sure. Keep us posted👍
I suppose it could happen. I wont be doing much faster than some high performance cars would go so id bet it'll be ok. If not, we can all learn from it here together right?!
This is cool! This approach got the gears turning for me now…🤔🤓
I can only imagine what spin the DA team could do with it! Thanks for always watching and commenting👍
Josh that is bloody awesome...I have never seen that done before.....Mike Patey would be proud :)
Thanks mark!
Outstanding work and that soundtrack is 🔥
Hexagon shape! Great idea! It looks awesome!!
Thanks👍
Just got through the cowling series. GREAT solutions for producing an extremely complex part. Love the hex stiffeners!
Great to hear from you! The Hex did turn out really cool looking! Thanks for stopping by.
I really love the style and the approach
The hexagon make it look way more better
Most importantly it's rigged
Thanks!
Experimental aviation at its' best! Great work.
Thanks!

Thanks Jim! I really appreciate the feedback👍
I'm impressed Sr.!
very smart and ingenious
Thanks!
Great work and the techniques you are using are inspiring me for some custom layups for a car hood design. Keep on going with your project!
Thanks!
I love the included logo. Crazy cool design and never seen before.
Thanks Doc!
Great work. Cant wait to see more!
Thanks man!
looks great!
Thanks Pete!

Great job. Kudos to your process and hat's off to you.
Appreciate that Steve!

Looks great! One suggestion is adding chapters in the video so people can skip the speed up footage if they desire
Thanks! I’ll look into how they do that, never tried. 👍
Looking forward to the next episode. Have a Happy Thanksgiving
Thanks for watching!
That’s really cool.
Thanks!
Great work as usual!!
Thanks man!
I love it man, the process is fantastic! Excellent work!
Thanks Keith!
Smart!
So cool!
Thanks!
How would I have done it differently? By consulting you! Looks great, and I too like the logo.

@@Project2Aero you are a true fellow. Thank you man 😎🎩♠️
Is there a reason you haven’t reinforced the lower cowl, as you did the upper?
I do suspect some of the lower half will get the same treatment. Working through a few other details before I make the decision on that.
Have you considered if it is possible to over speed wind milling the electric fan when flying ? Just a thought and I am in awe of your work !!

what is the thickness of the walls
What resin system did you choose to use ?
@@theroman21 I used west system 105 epoxy👍
