Posted: Fri Sep 09, 2011 6:31 pm Post subject: Nose Rocker |
|
|
I am making another board right now. It is 50" long by 20" width parallel rails and I am using 1/2" marine plywood. This is going to be for bigger juicier waves.
1) Nose Rocker - Is it necessary? The rest of the board will be flat. If it will help, what is the best way to put it into the board?
2) Finish - I want it to be as maintenance free once it is done. What are best choices?
Thanks in advance, Spudnut |

I don't think nose rocker is necessary, although a little doesn't hurt. Most of my boards have been flat. I had good results applying marine epoxy for a finish(no glass). Not cheap, but quick to apply and dry. It does add extra stiffness to the board, but it's very durable. |

Use of nose rocker is largely a function of whether you ride forward or aft on your board -- which part is planning on the wave. If you ride forward you don't want much rocker or the board will be pushing water. _________________ rodNDtube

Scarf a double thicknes of the same plywood onto the nose, and you'll be able to put a little sanded kick in the nose. You also get a nose handle.
On this cubit board I shaped the inside (thumb side) of the handle before I glued it onto the nose. Some people like to grind a taper on the deck side of their nose blocks. I like an abrupt edge that my thumb can firmly grip.

i did an experiment a month or so back, i bent a board with a very abrupt nose then surfed it back to back with a flatter rocker version. the steep nose was horrible, harder to catch waves (i believe it pushes water more) and harder to flex.
finish wise i do all my boards in boiled linseed oil. it gives a lovely natural finish, super easy to apply, you get grip (unlike a varnish board) and with use gets a lovely patina. _________________ www.traditionalsurfing.co.uk |

Thanks for all of the great replies. I now have it shaped and sanded. I have some polyester resin. Would that be a decent choice? |

IMIO (the second "I" is for ignorant) gradual entry rocker is far superior to abrupt as far as pushing water.
I do believe that the amount (and type stiff vs soft) of flex has large effect on how much rocker helps or hurts the ride... |

The board is done! I made it with no nose rocker, dead flat throughout. The more I thought about it, I decided against resin. Woodcraft had tung oil on sale, so I picked up a quart and put on 4 coats at 1:1 with thinner. |
