Hi Tom.TomW wrote:Hi Grant,
I'm also building a strut, 70 cm long. So far, I've built a 7 layer Abachi veneer Core and shaped it, with compensation for a 3mm wall thickness of CF.
I've already purchased biax in 300 gsm and twill 450 gsm. I also have some 15mm wide Cf tow tape I could add. Sounds like I should of purchased Uni d too.
My plan was to vbag on 4 layers of biax and 3 strips of Cf tow each side, clean it up and then bag on 2 -3 layers twill.
Then I will attach strut to a plate and v-Bag on more twill.
Any recommendations welcome

If we go with 70/30% are the numbers right? Coz Uni 300g is 1/2 of Biax 600g, hence 3x300=900, 2x600=1200
Maybe swapping 300g uni for 600g, that sounds better?
But with 300/600g we need to remember that 5 layers of 200g makes it about 1mm thickness. The weight variations significantly change the profile thinness, as we know.
Tom, to answer "5kg, 80cm out test" - the core is very fragile atm, I do not want to break it
