Hey guys
I'm quite excited Hence opening a new thread with a final product!
At this stage it is a prototype. But, a promising one!
First, some triax 700g/m^2 cut into this shape. It is extremely important to cut it for your mold.
See this gaps? Orange color is a rubber swimming hat. Will keep it for a better seal.
After positioning I am after no gap at all and a second cut will fix this.
Than goes carbon kevlar wrap (sorry no photos, stressed out 100%).
Vac this baby! Using ziplock bag and one way valve. Keeping vac for hours!
I'm always exited after taking it off a vac bag!
Cutting off the mold! Yes, cutting with carbide bit is not for a faint hearted:
Happy days! 183g !!!! Not finished yet, and there is a space for some weight reduction (KC only?)
Nice hey?
Curved back side reinforcement:
Now a few epoxy coats and with a PU varnish, some EVA inside or even neoprene, strap and that is it! Hoping for less than 220g. Light as feather!
Btw, it is hard as a rock! It can't even be compared with a Gath (sorry Gath!). I recon there is no way to smash it with a hammer, but if I'm super keen will destroy one for sure:)
Already planning a next one! Same KC + FG but one layer only. This has got two. The mold is fine, can be reused number of times. Just some more plaster to fix the cuts after demolding.
My ultimate goal is less than 200g!
Hope you like it!

PS
Cost? About Au$35.
