T-Belly Gen 2 Build...

This is the second post on the T-Belly G2 build. The blank was given a sealer coat of epoxy resin and cabosil. The sealer coat helps to fill in the tiny pock marks left in the EPS foam after shaping, helps to prevent air from escaping the core and causing delamination after glassing, and generally provides a good adhesive layer for the lamination. After sealing, the blank was air-sprayed a light grey color. At this point the blank weighs 2lbs 4oz. Since the blank is stringer-less, I decided to use a layer of "VectorNet" between the blank and the 6oz cloth on the bottom. VectorNet is Kevlar netting woven into some very fine nylon mesh.

I'm hoping that the netting will provide torsional strength without the stiffness that you  get with carbon fiber. Here's the VectorNet draped over the blank prior to trimming.

And now, trimmed, with a layer of 6oz E-cloth. Normally, I would use 4oz cloth, but the VectorNet causes ridges beneath the fine, 4oz cloth, which can lead to sand-throughs during the sanding process.

And, finally, laminated with epoxy resin and "pulled dry", eh?

The deck will also get a layer of VectorNet, but only in the back half of the board where the rider will be. I'm hoping this lamination process will yield a board that is strong and resilient, but also has a little flex.
