paulownia + polyester+ fiberglass: rocker and flex

Unread postby asier esnal » Thu Nov 29, 2018 4:51 pm

First paipo prototype made in paulowia polyester and fiberglass. It has been much better than expected
I want to thank Sergi Flama Galanó and Patxi Navarro for their great help and all of you from the forum that make it so great

the paipo is a 44x21.5x18mm of paulowia on a single board, I put it on top of a board with a block on the end, 90mm rocker. I have refined it I have not done any previous treatment, neither heat nor wet, I have counted it to contrabeta is the most important of this idea

I have enfibrado with a cloth on each side of 6 oz and uv polyester. After the release, there is a 60mm rocker with an elastic bed flex, very noble, not bamboo type. when putting fiber and resin has picked up weight, it has remained in 3.2kg

I leave you a video of flex, I do not know how I can do it so that you see it directly in the forum

it's already finished, I'm a little afraid of the weight, it's been 4kg counting the fins and everything. Will it float enough? I have to find a way to lighten

You can remove the fiberglass and resin and paste a thin sheet of melamine, synthetic wood imitation veneer and many colors to make furniture

Treat it as an experiment. Try it without fins. It may be too heavy as you don't need to even glass pauwlonia. Oiling them can give a good finish.

Without fins and fibreglass these are low flotation boards - they will have their place. You won't be outpaddling SUPs.

to get the rocker and that flex I have to cut the wood in contraction direction to the feed, if I do not give fiberglass part by just touching it,

I do not like the paipos without fins, nor the bodyboard, I hate the lateral displacements and skids

Do you use google translate? I'm not sure what you mean by: "if I do not give fiberglass part by just touching it,"

You'll find these thin wood boards don't spin out like foam boards or boogie might. They are a different craft and sit in the water more.

The real test is in the water.

Do you use google translate? yes, unfortunately I have no ability to learn English, I have tried . I have dyslexia, this gives me a very restless mind with a lot of creativity, but it prevents me from writing and reading. I can not have everything in life, I'm happy as I am

I'm not sure what you mean by: "if I do not give fiberglass part by just touching it," the wood is terribly weak,

They are a different craft and sit in the water more.: I'm very happy to hear this. I'm going to give the paipo a few hours in the water to draw conclusions, maybe with only 2 keels and smaller make the function, I always have time to put another 2 plugs in the middle of the 4 that I have put.

the paulowia costs me 20e per paipo, it allows me to make a few paipos

Thank you very much for the recommendations

Ok, if I understand you correctly, you are saying you needed to glass the board, because the wood is too weak. It is a light wood but shouldn't be too soft (you shouldn't be able to squeeze it and make a dent).

Try the board - you'll soon know if it works or not. If it doesn't paddle too well, it may be a shorebreak board.

Enjoy the ride.

Bob, I think he meant that it needed glass because he cut it out so that the grain runs across the width of the board to increase flex; but that weakens it considerably so--glass. I really like the look of the flex in the video/FB link. Nice and springy.

Asier esnal, thin wood board like that one, the edges can act as fin if you properly use your hips and hands to push them into the water/wave face. It is a different style or method of controlling the board than for one with fins. And no fins is faster! ;)

I spent a bunch of time in Ecuador. Though I knew a little Spanish and was studying it, I had to use google translate a couple times for critical banking issues and it would have been hilarious if there hadn't been so much of my life's savings on the line! Total slap stick comedy with officious, Kafkaesque, bank prigs and regulations.

perfect, that's what I wanted to say, I feel the confusion, I do not know how to solve my writings in English, I'm really sorry
