• Why are you using a foam core instead of a honeycomb core? Impact resistance? Or easier to bond in the hub? Or simply what's left over? Should be a fair bit heavier than honeycomb, right?

  • It’s easier to cut (main reason) and it’s better in compression and shear than Nomex. You’d usually use Nomex on thinner gaps. I shaved a thicker bit down to the correct thickness. Bonding it in is no different as I’ve used what I believe is the strongest 2-part epoxy adhesive available. We’ve got stronger adhesive films which are lighter, but I’d have to tape it all up and vac bag it, whereas with this I can just spread it on and weight it down on the surface table overnight. I forgot to take a pic before I put it together!
