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.
i dont mean to be so offtopic but does someone know of a tool to get back into an instagram account?? I was dumb forgot the password. I love any assistance you can give me.
@Oscar Angelo Thanks so much for your reply. I got to the site thru google and im waiting for the hacking stuff atm. Looks like it's gonna take a while so I will get back to you later with my results.
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?
Check out Stretchlon 200 from Airtech. This is a thin elastomeric vacuum bag, which isn't so much more expensive than the usual nylon. You will save time and wrinkles ! Keep on !
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.
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.
Sorry about that, it was just a knee jerk reaction to even the word 'bondo', I see the evil bondo was only in used in the templates. @@chrischristiansen5260
Thanks for watching! Ok once I had a good template, I traced it onto the foam sheet. I used a jigsaw to cut up to the line. I then used a drum sander to sand carefully to the line. This also ensured that the flange was 90 degrees to the rib face. A round over bit in a router finished off the corners.
I admire a man who can go public with something that isn't going perfectly to plan. Alright in the end, though...

@Oscar Angelo it worked and I now got access to my account again. Im so happy!
Thanks so much, you really help me out !
@Torin Karter Happy to help =)
Hello ! There are no more videos, too bad it was really interesting

Nice, reminds me of how we used to make motorcycle hugger fenders
Hey Chris. How did you know how thick to make the CF part for your aircraft? I always make things thicker because I don't know for sure.
Thanks
Hi Chris , just found your videos awesome! Why dont you post anymore videos ?
Hi.I gone this way, it so hevi.
God lak Chris.
Love your videos, please keep making them... Best of luck on your dream machine, I know you got this 👍
Thanks man!
I say the same!
Try using compressed air to remove the plugs. :-)

Chris, can we get an update on your project?

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

There's no bondo in that foam plug. Hard to release cause there's zero draft.

How did you make the plugs using a hot wire cutter, cnc machine?

Leave a 1" diameter hole so you can use a press to push the plug out?
if you spray your plug with something like PAM ... you will pull the stuff off easier btw
Is tis for a propeller driven aircraft or a jet powered aircraft?
Good Stuff how's it going?
Would you care to share the type and kind of aircraft you are building?
How to make a carbon flyer wings or whole mold
👍🏼👍🏼👍🏼
Any updates?
Chris, what happened to you and the program?
Still alive
He is not making any more videos, so we all know by know how strong that carbon fiber was...
because carbon fiber strength is directly related to video posts.
Is this channel death.. Rip..
