Here is 4 frames per minute video of this build out. This board is 23.5" wide, 3.25" thick, at nose is 18.5" and tail is 16", and has our Evo rail foils. It will have 2+1 fin array but will probably be surfed with a Bing 10" Hatchet fin only.
I started to sand with new 5" Dewalt disc sander but too much noise and did not like the results. Seems in talking with other HWS builders, there is a point where you are tired of noise and just do it by hand. Actually hand sanding is rather rewarding. You can see your work as it changes from gobs of glue and hunks of wood into something that has a bit of your soul forever in it.
