A Couple of Earlier Boards

Heres a few links to some earlier boards which I did build threads for on Tree to Sea.
They explain in more detail the building methods I've tried.

Heres a youtube of the oiling process





This is the last coat of oil on my hollow wooden mini mal. There were 3 previous coats .
The 1st coat was    35% tung oil + 15% orange oil + 50% citrus turpentine. I used about 200ml on the 1st coat - the raw timber really soaked it up.

The second coat which I did 24 hours later , was the same 70/30 oil mix with only 33% citrus turps. This coat soaked up about 70 ml.

The 3rd coat I did about 5 days later [ each coat takes longer to dry - depending on weather conditions]. This coat was 70% tung oil + 30% orange oil, no turps. It soaked up 50 ml.

The 4th & final coat I did 8 days after the 3rd. For this coat I used 50% tung oil + 50% orange oil. I used more orange oil as it is supposed to help the tung oil harden.

As you can see by the photo below the water beads really well on the oiled surface



Third Wooden Board - 7 ft x 20 1/2 inch mini - mal

Heya - Craig here -  I live in the Caldera region of northern NSW overlooking Mt Warning (Wollumbin).  Been dabblin' with hollow wooden boards for the past few years now - learning the skills required - & feeling the buzz of making my own wooden surfsticks.  This one posted here is my most recent one a 7 ft mini mal which has a tung/orange oil finish.It has a 6mm marine ply spine & 6mm paulownia ribs . The deck skin is 7mm paulownia & the bottom skin is 6mm paulownia. The ribs are spaced 150 mm apart- plus on the deck I added small intermediate ribs between the main ribs for extra strength & on the bottom I added thin 2mm balsa sheets- it feels more than strong enough. The tail & nose blocks are made of black wattle & huon pine. The fins are made of camphour laurel & red cedar & are glassed with fibreglass. The inside is sealed with varnish & the airvent plug  is 10 mm stainless steel. It took me over 200 hours to complete which is a lot - but I'm real happy with the quality of the final board.
