(IMG:style_emoticons/default/blink.gif) The smaller, the more difficult for this kind of stuff...... Have a look on my blog (in signature). There is a page for models, and you'll find in the middle of these albums a part where you can see the method I use to build the skeleton and the shell of RC boats. Simple, but you must be very careful with all alignement and symetry aspects !!! Good luck |

(IMG:style_emoticons/default/blink.gif) try carving the hull shape out of foam and laminating the balsa over the foam. you can either use a mold release wax or just carve the foam out after the resin has cured. |

There were 2 canting keel models at Hamo this year.
One was a scale of Wild Joe and the other a scale of Wild Oats 10. Both were fully functional. |

I hope it is clear enough to understand the right process Good luck

So for an un-cored carbon skin hull, you shouldn't need as many bulkheads as pictured, right?

Oh, I didn't know those would come out. Makes me worry quite a bit less. Thanks.

all the frames (correct terminology) that are removed after the hull is built are called mould frames, the rest are frames, and generally a frame will have a beam across the top as well so that it is stronger

Next step : buidling of the mold
On the wooden hull, I made a complete finish with gloss paint, then several layers of wax, and then epoxy/glass lamination. Once it's hard, you split it, and you have a mould ready for production. With this model, I kept the wooden model as sailing hull, so I took off most of the frames to save weight and I kept the ones necessary for keel and rigging reinforcements. Pictures will talk by themselves

Here is the wooden hull after lightening a little bit.
You will see also a GRP/Carbon hull laminated "classic" way in the mold, for leisure VRC. At the end, you'll see my racing boat, done with vacuum bag and epoxy/carbon lamination. 300 gr. for the bare hull. This post has been edited by sylkill: Sep 3 2007, 06:19 AM
