Board # 26

Shape time including template creation: 3 hours

Glassing /Sanding time including fin boxes: 4 hours



Special thanks to Sean Puckett for drinking beers while making sure the shape was straight!

Extra special thanks to Probox-Larry!

These boxes went in pretty smooth, I need to get some sort of squeeze bottle next time to top off the route after the box is in place, but that’s on me.

Thanks again.

5/8" Deck Channel

Made W/ 1" PVC pipe section, Super77, 100 Grit Sandpaper and a homemade perimeter guide.

I shaped the Channel after the board was completely shaped.

I then lammed the bottom of the board onto a tapeline, cut the line w/ a razorblade when the glass had kicked and sanded everything smooth.

Before the deck lamination I brushed a thin layer of lamination resin into the channels and waited for it to kick and become tacky.

When I layed my cloth out on the deck I carefully pushed the cloth into the tacky lamination resin carefully making sure the glass between the channels was flat and tight.

To save weight on this board I made a deck patch just inside the Channel so only one layer of cloth is in the channel and lapped around the rail.

My thought was that since the Channel itself provides additional strength to the rail, I can get away w/ having only one layer of glass on the deck lap.

I tried to pull out excess lamination resin from the channel by running my finger down the channel just before wrapping the rails onto the bottom tape line (I tape lapped this board for consistant strength).

After that I hotcoated both sides as I would normally do.

Then I sanded as I would normally do.

Finally I took the same sanding jig I made to shape the deck channel in the first place, wrapped it in 150, and sanded the excess hotcoat resin from the channel.

This was the first time I have ever glassed a channel and it all worked out great. It took alot of planning and carefull application of the pre-tack, cloth, and hotcoat.

The End.

like it. like it a lot. We’re going to need a full report after your test drive.

I’m pretty much sold on the quad thing. All the drive of a thruster with the loosiness of the twin. And with probox, you can adjust fore and aft for just the right feel.

But the board is white. Can’t you do something about that? ha.

Love the board! It should do well for a guy of your weight. Can’t wait to hear how it went!

dane, Very clean board! REALLY like the channel deck, glade to see your ProBox experience was a enjoyable one. Mahalo,Larry

The quad seemed to work very well. On rail through a bottom turn the board picks up speed and is very fluid. I rode the quad all weekend in heavy overhead surf @ Baja Malibu. The grip was just as good if not better than a thruster and because the board is 20" wide I was able to get into waves early. One nice thing is that I was able to bottom turn around sections really easy. All in all I would have to say the quads are really cool. As for the all white board?..everything I own has some sort of art work I have done on it. I thought that a stark white board would really show off the shape and attention to detail. I am sure I will draw all over it soon, I will post photos when I do. In the meantime please enjoy this drawing I did between sessions at Baja Malibu this weekend. -dane
