Step 1: Step 1: Get Your Boards Ready & Do Some Drawing
* 2 Paulownia wood planks (about 220cm x50cm x1.5cm) you can use any other wood, but Paulownia is nice and light and still robust
* paper and pencil
* sandpaper 80 120 280 300
* eccentric grinder/sander (or you just use the sandpaper manually, it only takes longer)
* electric jigsaw (or hand powered...)
* wood glue
* Sealer (linseed oil or ship paint/varnish)
* clamps to secure board on your workbench
First make sure to glue your wood planks together, this will take about 48hrs to dry, make sure to clamp the planks together properly. Best is to draw the shape of your board you want on a paper, then pencil a grid onto your planks and then re-calculate from your small scale to the big board scale.
Put the measurements on the board. You can see the rough outline of your board now.
Step 3: Step 2: Cut 'n Shape
Now make sure to clamp your plank to a workbench properly.
Get the jugsaw ready and cut along the outline you have drawn. Now you have a very rough cut of your board.
Step 4: Step 3: First Sand
Depending on your wood, you might want to go to step 4 straight away.
In my case, the wood was a bit rough , so I gave it a first nice sand with 80paper.
NOTE: use a respirator mask, when sanding, the fine dust can cause lung problems.
Voila, already looking a bit more like a board ;)
Step 5: Step 4: Shaping
Clamp your board to your workbench save and secure. Now it is time to get the edges softer as well as adding a rocker to the bottom. Get your favorite slicer/plane and work on all the edges, making them smoother and rounder. Once you are happy with your out line, you need to add a rocker to he bottom of your board.
Step 6: Step 5: Adding Rocker
For your rocker, it is best to draw an outline again how wide and long you want it. Usually the rocker is about 2/3 along the bottom of the board. Get rid of all the wood with a good slicer, till you get to your desired depth and width.
Step 7: Step 6: Sanding, Sanding, Sanding
This step is all about sanding down your board from rough to fine. Start with the 80 paper, make all edges nice and smooth, as well as the bottom and the rocker. You can also sand away some wood from the nose at the bottom, to get a slight curve. Work your way around your board, changing the paper to 120, then to 280.
I used the electric sander, because it is a lot faster and easier! Although, the last very fine tuning, I did by hand.
You will see how nice the wood feels the more you sand it. MAKE SURE to use a respirator mask while sanding, the wood dust is very fine and cause lung problems!
Step 8: Step 8: Oil It or Paint It
Voila, now you have an ancient Alaia Surfboard. Traditionally you should oil it with linseed oil and rub it all in really well. The wood will turn darker and get a nice glow! It will also protect it from water.
The other option is to use ship paint, this will also protect it from scratches more than oil only. Since Paulownia is quite soft and I found that my board does get dents easily, I use clear ship paint.
Happy shaping ;) hope you will have as much fun as I had!
