A sad spectacle of unskilled work.

That is one of the hardest and material intense methods of making CF ribs. There are many better ways. In this case, make one large flat sandwich panel and then do the flanges as a secondary bonding operation - no molds needed. The flange material can be made easily on a piece of angle aluminum.

Small point. Don't use bondo, ever, when making these quick 'n dirty molds. Just don't, never. Keep your materials in the same chemical family and use an epoxy+micro-balloon slurry instead of bondo. Release agents do not seem to work well over bondo, which is why Chris had a hard time popping that piece off the mold. (Yes, it would have been hard anyway because that shape always is a bear.) But apart from that small point, thanks for the great video and your talented work. Great work, Chris.

Are you going to do a video explaining how to build that Hotwire tool? 👍🏻

Hello ! There are no more videos, too bad it was really interesting

I'm very interested in using carbon to build my aircraft. Knowing little to nothing about it my question is do u use fasteners to install ribs to spar? Or glue?

I am deep into the calculations for my single seat design. I try to avoid complex production technology. Now I see you build plugs for a single airplane. Yes, this makes it lighter! Would do it again ir would you save work and use a simpler method?

Did you spary paint into the mold before layup?

Chris, what happened to you and the program?

Is this channel death.. Rip..

Would you say what epoxy resins you used (brand, type)?

Good pace, nice, accurate job. Why did you wet the foam at all? I think there is plenty of resin in the skins to do that. Instead, I would recommend less aggressive perforation of the release film, around 30-40mm pitch. You should have breather half-dry ideally. If it gets fully impregnated with the resin, the airpaths are blocked and vacuum does not work that well. Also, just a recommendation... To get stronger vacuum, use a long aluminium perforate tube instead of single port. At least 1m long for such a job. Plus add another port in the farthest corner and use it just for measurement. This will truly indicate how good is the vacuum. Regarding vacuum pump, get yourself a nice little pump from Easy Composites. It provides excellent abs. pressure, is very reliable and does not evaporate oil.

Leave a 1" diameter hole so you can use a press to push the plug out?

Well made, poorly explained. What kind of foam? How many layers of carbon? What is a "special epoxy mixture"? So many vague descriptions. Wish this had a voice over instead of music. But thanks for attempting to explain.

How you positioned the foams ?

I admire a man who can go public with something that isn't going perfectly to plan. Alright in the end, though...

Can this be used for 3D filament

if you spray your plug with something like PAM ... you will pull the stuff off easier btw

What type and who thick is your foam core?

Hi Chris great video. What kind of vacuum pump you using? That's a very big pump.Best Regards

Nice, reminds me of how we used to make motorcycle hugger fenders

Chris, can we get an update on your project?

Any updates?

Thank you Chris.

Good Stuff how's it going?

A trick I learned doing concrete forms is to cut your plug in half, then tape it with the release tape. After the part cures you can easily pull the plug out in two pieces rather than one.

Can you show a spar being built? Are you familiar with the Marske spar? He uses carbon fiber rods embedded with wraps of fiberglass in a mold.

How is everything going? Are you still doing the project

How to make a carbon flyer wings or whole mold

that is only one surface of wing, how about the other, and how to connect them together with enough strength?

very cool work with carbon fiber, could you tell which software you use to develop your projects and could give tips from books to buy, for those who want to learn how to use composites? osvaldosurf2@gmail.com

Is tis for a propeller driven aircraft or a jet powered aircraft?

👍🏼👍🏼👍🏼

How do you figure out the layout of the different layers and orientation of all the constituent components of the carbon fiber.

I would put some shape into the web i.e. the flat part of the rib. Beads, dimples, anything to increase the rigidity while hardly adding any weight. Just like they do with a stamped aluminum rib.

if you have a passion as you do, at least your Girl knows where she can find you !

thank you very much for such a cool demonstration. For your sick, however, I would like you to build a autoclave around that wooden tabletop where you brought the temperature up to whatever it is I guess a hundred fifty degrees. You have some potential to have droop in hot weather and you aren't too strong without autoclaving

Hi Chris , just found your videos awesome! Why dont you post anymore videos ?

wow, crazy precision by hand

He is not making any more videos, so we all know by know how strong that carbon fiber was...

Can u built wings for a cessna 210?

What the material?

So how long does it take to build everything?

You can melt that foam out with Acetone. Will save you a ton of time.

Try using compressed air to remove the plugs. :-)
