You're taking Cardboard-Aided Design to an entirely new level. This is amazing.

[@mad-cyantist3159]

Just seeing how focused and how you problem solve before hand is amazing.

[@richardsmith9509]

Perhaps, but there is a lot of incorrect products and techniques mixed in here...

[@jamesburnett7085]

I keep trying to believe that you really do know all this stuff, but it has to be impossible. Yet, there you are, proving that the impossible is true: you know exactly what you are doing. For all I can tell, you are an expert at each different job. OMG! What is your background? You didn't get your knowledge and skill working at the drugstore!

[@BuilderCreator]

Half is knowing what you are doing. The other half, is just jumping in and committing yourself to figure it out. Ha!

Amazing build

[@BuilderCreator]

Getting to the "amazing" stage. Used to be just parts, now coming together as a real car. Yeah! Thanks for following the build

[@eulerizeit]

I worked on Syntactic foams in grad school, never really seen one used until now.

I was waiting for this.

[@BuilderCreator]

I hate making others wait. Glad to oblige. Anything else your waiting to see?

[@DavidG2P]

Whoa, that A-pillar looks sleek -- and all that in "only" glass fiber! Will it have enough strength to contribute to the closed profile that you need for torsional and bending rigidity of the monocoque?

[@BuilderCreator]

Very little load is transferred through the "roof" structure. Most of the loads are all through the floor, tunnel and side seals. Still much more structure being built into the tube that you will see in future videos.

Packaging tape layers work great as a seperation layer for composites. Mike Patey might not fly without it.

You should link the tools above to your Amazon store. At least then, if we want one we can give you the credit.

[@lennym1273]

Ever time I tried expanding foam the heat from the fiberglass or even body filler would softin the foam and it would cave in, I tried covering it with 3-M tape and it was better but still have the cave in.

[@BuilderCreator]

Are you using Expanding foam insulation out of an aerosol can or two part mix pour foam? The aerosol foam is very inconsistent and soft.

[@lennym1273]

@@BuilderCreator I tried 2 part and I tried foam boards from home depot.

[@Nevertrustalawyer]

I’ve worked with fiberglass and I would have to agree the vibrating saw looks like it works great. It also appears that the dust in minimal?

[@BuilderCreator]

For sure, much less dust!

[@aarondcmedia9585]

Could you do this in reverse and have a mould for the door sills that is upside down and therefore the right shape, fill it with expanding foam, then once cured attach it somehow to the frame? Or is the adhesion of the expanding foam necessary at pour time to attach it properly to the fibre? Loving this series, just outstanding, thank you.

[@bobdavis3389]

Have you ever used the expanding foam out of a can ? I've read where it holds moisture , T or F ?

[@BuilderCreator]

I have. only for bonding foam together. The pour stuff is cured in 10 minutes ready to be cut/formed.

[@bubbasattler4531]

What is the blue slurry made of? Epoxy & ?

[@BuilderCreator]

Epoxy and microsheres (or Q-cells) Mix your epoxy and hardener then add micro to the desired thickness. Wa-La!

[@BuilderCreator]

Thank you! Cheers!

[@daemonsoul1989]

Are the foam core/fillings structural? Or are they just used to form the fiberglass around?

[@pashakdescilly7517]

The foam cores are non-structural, and serve as a base for forming the fibreglass.

[@SETHalpine]

If you have 2 layers of fiberglass+ 10cm foam(or nida)+3layers of fiberglass is much more rigid and stronger than just 5 layers of fiberglass, It can increase the value of rigidity/stiffness by 5, by 10...with only increasing the total weight of 10% by adding foam

[@BuilderCreator]

SETHalpine is correct in that the foam adds to the structure, however the two part pour foam I used in the door seals is not particularly designed to be a structural material. It could be removed and the box structure it helped create would stand on its own. Even though I am trying keep a reduced weight the weight of the foam is not worth my effort and time to chemically remove it.

[@tomtheplummer7322]

Plus the foam dampens vibrations and sound deadens.

[@eddjordan2399]

roll over bar?

[@BuilderCreator]

coming.

[@richardsmith9509]

This two part foam is used to make custom drivers seats in Formula race cars. It is NOT a structural foam although structural foam is available. Did you look into that product???

[@BuilderCreator]

I'll probably use the two part urethane foam as it so fast. Don't have time for sittin around! Ha!

[@richardsmith9509]

@@BuilderCreator I think that structural foam is vastly superior to the two part stuff. You are betting your life on its strength and its just not the right product for that
