was looking at Russian collision repairs and found this after a half dozen videos.

Nice video

my dream car

Did you watch carefully how they vacuum bagged the inside of the intake manifold?

It hit me that you can bag the inside of a tube by making the bar a tube and feeding it through the middle and then joining the ends of the tubes together on the outside of the hollow mold. I am building a tube mold as I speak to test this and will share pictures if it works. This opens up a whole lot of possiblities if it works.

I encourage everyone to look this video over carefully. This is the highest end of carbon in my opinion.

Fred I also was "what" - How he did this??????? Waiting for your pictures.....

Fred i was all over those split molds they have on the table. mind bending and i love seeing new ways to do things.
for chevy trucks the frames are formed by water under pressure in a tube and mold to give it the final shape.there is very little we can do to repair them when the frame is damaged.
now--
tube that fits your need-- use a modified bicycle inner tube and the usual prep and let the inner tube press the cf where it needs to go to make a tube. use

Braided Carbon Biaxial Sleeve

to make a seamless tube. if you have access to any mandrel bent tubes you can make a two piece mold and have mandrel bent constant diameter bends if say you were making turbo or supercharger ducting.

i wonder if the inner tube idea will work with square or rectangular tubes as well?

Yes this is interesting, in my current project I will have to do a tube and I am right now thinking about a latex bicycle innertube and infusion,
but the problem would be the same as stretch bag and infusion I guess, the bag would stop the flow in the flow media.
How fix this?
A layer of un-perforated in between the flow and bag maybe?

Or maybe not a bicycle tube at all, regular nylon bag made to fit, the wrinkles might not be a problem.

Hi Scott
No need for the inner tube just the vacuum bag. At least I hope so. I have my mold made and am about to attempt to do this with the EC prepreg I just received. Just like you saw on the video you posted. re: the manifold clip where he is seen pulling the vacuum bag through the inside. I will show step by step pictures if it works for me.
Fred

very cool!!
