Just google a bit. I'm sure you will find some tutorials.
Tip: Modell aircraft hobyists often have a good knowledge of different techniques to build composite parts such as wings and aircraft fuselages. There are also some good books arround for sure.
The simplest way is to use the "positive" or "lost positive" technique (not sure about the term in english). You dont need a mould but you loose your positive (the foam core).
Prepare to make more than one wing until the result pleases you ;-)

Woo! I made a guide to cut out the foam and I just cut the outline of the first hydrofoil! Its getting too late and I don't want to re-injure my ankle so I'll cut the other half tomorrow. Then I need to make a hot wire to cut the curve. I also made guides to cut out the exact same curve on each side. I'll post pics of the guides tomorrow.
about curving its better to have the shape of the fish which is the best in water curved head and a tail but about other things i think u will have to try...

Hi Serafino,
Sorry for taking so long to reply... I am just now coming up for air on this lunocet project. I will send you a lunocet if you promise to finish yours and as soon as I fill some orders I have... keep your spirit strong bro, it's your most valuable asset.

I'm definitely going to finish this.Thanks for the support and I wish you the best of luck with your sub human project and the lunocet. What your doing is awesome and will greatly benefit research. If your even in California let me know.
I'm still waiting for someone to help with a hot wire at the moment. I should be able to cut the foam this Tuesday. If not I'll have to research some hot wire plans, make the wire on Tuesday and cut it Wednesday, then I can finally get some fiberglass wings made and keep this project moving. I'll post pics of the first part of the cut that I made with a knife to get the outline. Also some pics of the guides I made to cut the wings symmetrically and have the same hyrdofoil curve on each side of the wing.
Also does anyone have any good videos of a dolphin or whale tail in action?

My digital camera is broken I have to go get it fixed but in the mean time I used my phone's camera to take theses pictures. I used a hot "knife," actually a hot sawsall blade to cut out the foam using a metal guide. Then I put both forms on top of each other and scraped them with a putty knife to get them roughly symmetrical. Then I went over it again and refined them with rough sandpaper then finer sand paper. So now I have the shape of the wing without a hydrofoil my friend couldn't help me yesterday to make a hot wire so I'm gonna take apart a toaster to make one. Anyway enough talk here are some pictures of the wing the guides for the outline, the guides for the hydrofoil shape and at the end some of the projects I have previously taken on. I could only upload five so I'll add some links to other pictures
These are just my other projects
My recumbent bike I built.
The rocket that needs 400 dollars for a single launch
.
My bbq (this picture was taken before I finished it the reason why there is expanded metal on the bottom)
Below are the attached images of the foam that will be used as the mold.

Looks cool, Serafino! BTW, there is a new entry in the Lunocet Blog. It looks like you can throw away the metallic foot plates and use bicycle shoes with pedal locks instead:

I'm gonna stick with what I have for a few reasons
1. I dive off of northern California where its cold and I wear 5mm neoprene socks. I doubt those would fit in bike shoes and I doubt that if I didn't wear them I would be comfortable.
2. Bike shoes are expensive I have some bike pedals but buying a pair of bike shoes just for this would cost me way too much.
Don't get me wrong its a great idea I just don't think it fits my situation.
What I'm gonna do is buy a pair of shoes, cut out a piece of 12 gauge metal to fit inside then bolt the shoe to my plates that I have. That way I can tighten them up be, comfortable, and wear thermal protection underneath.
I actually welded together the aluminum foot plates last night I'll post pictures soon.

So sorry for not posting up in a while I've been drowned in another project called a Porsche lol. I bought myself a new car and its taking some work to get it reliable and fast. I did get a chance to work on the fin today though I'll post pictures when its light out tomorrow.
Sorry for the long delay I've been extremely busy these past few weeks with finals, and a few other projects. I just got the chance now to take some pictures.
Fresh out of the camera
The first one shows the shoes I bought I cut out a metal insert to hold the shoe down to the foot plate and pedal.
This one shows the footplate with the holes drilled. The bolt will go through this plate and into the pedal the shoe, plate and pedals will be held together with 8 bolts.
This one shows the arrangement of what I was just talking about.
Here is what it will sorta look like when its done except the pedals will be under the foot plate and a metal rod will extend into the fiberglassed wing. Woops! I put the shoe the wrong way in this photo its supposed to be upside down towards the top and have the pedal angle away from it,
This picture just shows the metal rod and probably how I'm going to position it inside the wing. I'm not sure yet though I may put it farther torwards the middle.
Again sorry for the delay I never expected to have so many. I'm gonna have to go buy some bolts and some nuts this week so I can get most of it assembled. Then get on the ****ing @$$ of my brother in law to finally help me make a hot wire so I can finally get a hydrofoil shape in the foam.

hey man well done so far waiting to be completed all... Is it aluminum welding there? did you do that?... Great job
All best man

Yup its aluminum. I used to be a whole lot better at it when I practiced it more often. It took a few practice welds on another piece to get my welds back in good enough shape to actually weld it together. I think I'll have some time today and tomorrow to work on it some more too.
