The internet galaxy & hydrofoils

Mahalo readers,
Not I am lazy, but simply no time on the running projects to be really accurate here and write
daily/weekly the news on the blog! Some of people are simply better on CAD and in workshops
at R&D, some of them are writers and good on social media pages.

Lets make some update on kitefoils under R&D.
It is true the post on Kite forum push me to write here again

Where the community found from Christmas card the Owing kite foil. Really happy to see some
of the people have really sharp eye on new products.

For me not new foil, the Owing was presented at TFW on Garda lake last summer
http://drlojz.blogspot.com/2014/07/the-foiling-week-garda-lake-2014.html
Where all the big minds of foiling world come together, to present and interchange the work, ideas etc.

At the moment the molds for "classic hydrofoil" are ready in production, I will post here the finished product!
The kitefoil is developed  for the www.ahcustoms.ch from Swiss!

 Main Crossover AH-foil wing mold


 Body mold finished
 Vertical half of the mold
 The negative V tail


Here some early comp graphic from last year! The Owing is under development and before summer is in plane to hit the water ;-)




Lets move the product to be simply as possible!

touch and go

  2. Agreed looks great, late to the comments I know. I use normal MDF for moulds and seal with Polyester resin. This looks really interesting and keen to try. What is did you bond the Corian to the Plywood with ? I also presume you first heat formed and then bonded it, 2 steps. I am also curious about the grooves around the shape you trying to make, whats the reason for putting those in ?

  3. Mahalo Kyle, same here, sorry to be late with the answer :-) MDF with polyester hmmm, a lot of shrinkage from this type of resin! Much better high temp epoxy and vacuum infusion ;-) for impregnation! what also work is the last cover with Formenharz /Mold resin and again on CNC for the finish path ==> grinding polishing :-(
    Corian or any other acrylic kitchen table material, yes first formed and then glued on wood base! I highly recommend to use Corian or original 2K glue, because epoxy bond only mechanical, take care!
    The groves/profiles around the shape, Ohhh yes! Basically shape for the rest of material at closing of the molds and to get perfect closing line! The trick/tip od good mold makers, because only this way your product come out in calculated dimensions! My heart is bleeding when I see the the non trimmed products, with the layers of CFK out to mold middle line! The result the product is for this dimension thicker!! If you like you can contact me direct on drlojz2@gmail.com, for more discussion :-)
