The materials finally showed up, time to get shaping.

Looking through your pic, did you get Surfacing Agent for the sanding layer? It will be mess sanding without it and the board will not cure well. Sanding Agent will cut the smell down immensely, and everybody in the house will be grateful. What is the bottle next to the resin (rubbing compound)? Did you get Catalyst, (Methyl Ethyl Ketone Peroxide)? You can buy Catalyst, (Methyl Ethyl Ketone Peroxide) locally at hardware store. Did you get inserts for the foot straps that can be positioned an inch or two either way. As a first builder having foot strap position variably can help. I really do recommend the book, Maui Boardbuilding and Repair by Bill Walters (ISBN 0-9630623-0-1), it was for a windsurfer, but the step by step concepts are exactly what you need. I am not a good shaper, but I can glass well and learned quite a bit from other Gorge Shapers and working at Fiberglass Supply. Send me a message if you want to talk about glassing. When I kept up my web site I helped several young people over the phone and email with their projects from Chile to Namibia to Florida. Post more pics on how the project is going. I did not see the face mask and gloves in the pic!

I didn't get surfacing agent. I am not actually building the board inside the house, I just took the picture in there. I will be doing it outside to cut down on the mess/dangerous fumes. The bottle next to the resin was the MEKP.

I do have gloves/mask, and I will use them. I was mainly taking this picture to document my progress on the EA project, so the panel of judges can see that I didn't just buy a board and say I built it in January, when I present it.

Thanks for the offer of help, I will definately take you up on it when I get to the glassing stage.

This is what most shapers are using theses days. http://www.shape3d.com

Have fun!

I finished the project, and will make a post with pictures and my procedure in the next few days.

Sorry it took so long to find time to type this, I had a bunch of unit tests before finals week, and a bunch of finals this week. The project was pretty fun (albeit a little tedious at several moments). I believe that the board turned out alright, and I'm happy with the shape, although the paint job is really mediocre.

To start off, I would like to thank everyone who posted anything constructive on here initially. None of the local board designers/shapers/glassers were willing to help, and it would have been pretty difficult to find information without the help of some of you. You all saved me a lot of time. This project was fairly time consuming because of the lack of direction from someone who knew how to do it, though the videos were fairly helpful. Additionally, the cold weather (I was glassing late November through mid December, during the 5-32*F cold snap) made the glassing process take a whole lot longer. Despite a couple setbacks, I got it done in about two months of only working a few hours every weekend.

The shaping process was probably the most fun, I ordered a 6'2'' blank, and traced out the dimensions I wanted onto the blank, then added one inch to give myself a wide mistake margin. The cutting didn't look great, but I shaved a lot of material off. After that, I planed the board in order to set up the concave/convex. Sanding took a fair amount of time, though the rails turned out pretty nice.

_________________________________________________________________

The glassing was alright, it was just annoying due to it taking a very long time for each layer to dry, despite me using a very hot batch (2% MEKP). I chose to do one 4oz layer on the bottom, and two 6oz layers on the top. Due to using heat-lamps to try to bring up the temperatures, I had a couple of heat spots. The spray-painting was easy, and looked alright initially (questionable color choice though in retrospect). Applying the hot-coat was really easy, and sanding it didn't take all that long. The rails have a couple of small depressions in the coat, but according to my mentor (Mitch), it isn't enough to really affect performance. I also applied a layer of car-wax to the bottom, hoping to smooth it out a little.

I will be routing and installing fin boxes later, probably before April. If a thin layer of resin took 1-2 hours to dry, I can imagine the amount put into a fin box would take longer. I see no point in having a functioning board before I have a plan to use. My mentor, Mitch, looked at the board in person, and said the shape is pretty good, though the finish looks like shit. He said it should ride really fast, but be a little squirrely. I am pleased with the shape, but I wish I hadn't listened to the Ace hardware worker who said that my paint wasn't oil based. I should have done my own research on it, as a result, my paint cracked on the yellow portion. I had hoped one of the local board builders would have been willing to show me a couple tips and tricks for the various processes, but some didn't want to share "secrets of the trade," and others didn't want to take the time to explain each step as they were doing it. One again, thanks to everyone who gave me information on constructing a surfboard, without it, I may have had to do a different project that would have been considerably less interesting.

Hope to see you all on the water!

I will add the fin boxes and fins in later when it warms up a little. Right now, it is too cold outside for the resin to bind quickly enough.

I run the engineering class at school and could help you build a board. We have the CAD software and a CNC router in the wood shop that could make the job a little easier. I also glassed hundereds of boards for Shuler back in the day. Drop me an email jeffblackman@gmail.com
