Hi Tom. I saw your article in Sport Aviation March 2023. You inspired me to think about pitching a 1/2 scale B-25 EAA Chapter project based 100% on your experiences. You are a craftsman of the highest order and a genius.
Very inspirational project! I enjoyed your clever construction technique and hearing your thought process. Thank you for sharing! Hope to see her fly one day.
Spreading with a stick is a great technique! Another idea that helps reduce the over saturation of the carbon is to place another layer of clear plastic over the laminate after applying the resin and then use a squeegee to squeeze out the excess resin. To maintain the inner diameter of your ring rib you could mark a circle on the plastic as a guide instead of eyeballing it.
Still knew in the process of making carbon fiber for Aircraft parts. Thank you for sharing some of your techniques. I hope you can share more coz I really want to widen my knowledge about this kind of passion.
From the most recent question, it appears that you may not be answering, but I'll ask anyway. I like your approach to your mold design with the circle that you can tighten, the shape of the key block, and the screw in each block to help remove it. How did you come up with this approach? What "mistakes" did you make along the way that got you to that approach?
no stress to reply re tooling material Tom your video showed with ply, like all things should have waited to the end and all would be clear Great video many thanks
I understand it's a bulkhead (frame!) Are there descending size arrays of bulkhead forward or...to the rear empinage? What's the skinning plan like...?
Infusion will always provide a more accurate ratio of material to resin. That's why production manufacturing where Finite element analysis can be used to calculate material strength. Typically brushing it in will result in a higher resin to material ratio which isn't necessarily bad for strength but weight per piece and resistance to fracture may be affected.
You can get decent composite by wet lay-up BUT you need a vacuum bag. Many German aircraft manufacturers still use this method with automatic resin dispensing which makes it a wet-preg.
Is this your experimental B-29? If so, where will the pilot sit? I notice the nose section doesn't have ribs and another video of yours shows you making that out of carbon fiber. Will the pilot sit in the nose looking forward? Yet another video shows a large dome on the top of the fuselage - will the pilot's head be up there?
Lol... us older folks don't really like these Damn computers but I'd love to be this guys shop boy for awhile so I can build a new experimental amphibious airplane, your uncle Rules!!!
it's like winter outside ... so not winter just looks like it feels like it and is about the right time for it ... lol ok so what s it if it isnt winter ... lol walks like a duck talks like a duck barks like a duck ... must be a duck lol ... ok couldnt resist . ok enough of the valley girl speech lets get on with a video lol
Do you think it’s safe the way carbon fiber airplanes are not held to the frames by rivets? To me it seems like a bad idea given the constant pressure and temperature changes. To me, it seems like a bad idea, and wouldn’t it tear or breakdown sooner with UV or Infrared rays? The skin of the planes are held in by aluminum brackets glued to the aluminum frame……..hopefully you can do some research and tell Boeing because as it seems right now, I just don’t understand how a 787 airplane can hold 33 Thousand gallons of fuel. That is like the truck that refills gas stations.
Also if planes burn little fuel when up high in the sky wouldn’t that mean there’s more oxygen the higher you go? That is why planes burn little kerosene the higher you fly because more oxygen ignites fuel at a lower temperature and burns hotter…..Also in space is pure oxygen. That is how they are able to operate the thrusters. Please let me know your thoughts.

Nice video - very informative, methodical and efficient. Looking forward to watching all of your other clips

Hi Tom just found your channel many thanks for sharing

Really nice technique with the stick... fast and you can see if you have adequate wet out.
I understand it's a bulkhead (frame!)
Are there descending size arrays of bulkhead forward or...to the rear empinage? What's the skinning plan like...?
Do you have film on that fuselage...?
Also how do you test carbon fiber and resin for any contaminates?

incredible craftsmanship
weighting Epoxy is the only safe way to epoxy, Ask me why I say this. I have used over 20 gallon of resin. in 40+ years of doing modeling
Tom is that tooling board used in your lay up tooling?
Fascinated while watching you build this. Great detail and content. May I ask what exactly "The Project" is??
He's building a 35% scale B-29. I think it's meant to be flown
@@GreggGermain-lk8if Check out EAA Magazine Sport Aviation volume # 72 No. 3 dated March 2023. It's amazing!
Yes...what is the project, and that “tube”.
Where can information be found?
If you are referring to the circular mold, I believe that is a fuselage bulkhead.
Is this your experimental B-29? If so, where will the pilot sit? I notice the nose section doesn't have ribs and another video of yours shows you making that out of carbon fiber. Will the pilot sit in the nose looking forward? Yet another video shows a large dome on the top of the fuselage - will the pilot's head be up there?
Are you sure you're not building a hypersonic misisile
Great information and technique, just keep doing things your way, great stuff.
Can you help me with my project
The fact is your working area does not meet the standard cleaness room that required by FAA or EASA
UNCLE...!

ok enough of the valley girl speech lets get on with a video lol
Once again...a bulkhead.
U have film on skinning said bulheads?...or is this just tutorials to mfg. Bulkheads with C fiber.?

@jeremeyhowlett6773 less drag up high because of reduced air density
