Latest update.
Have sanded the deck, removed the 4 rods left by cnc process, begun tidying up the tail and nose and removed the seam around the rail left by the cnc process.
The rods were difficult to remove accurately. I took a lot of time to get that right so I didn't take away to much foam.
Whilst the cnc process is very accurate on the bottom contours and deck it can't get the rails to the same resolution as the 3d file so they will need to be hand shaped to get the tuck and roll working as designed. Basically the rails come out of the cnc process Harder than designed. So that means I need a proper shaping stand to be able to rest the board on its side to get the rails accurate. I've got an idea for an attachment to my horses made from scrap in the garage.
Been trying different sanding mediums. Love the 150 grit plasterers mesh.
Still need to smooth out the rail/deck transition, plus nose and tail and finish the bottom but the blank is getting there.
The thing that has surprised me is how small the board looks. Thats the first win. Not sure how that will translate to the waves yet.
Photos or it didn't happen.
