Hi, seeing the graphs first thing that shot through my mind was that it prooved what I read before, that plane surffaces on a wing are super ineffciant.I always wondered if that flat surf fins are just because fo the cheapness of shaper and industry ...anyway. What stroke me, too, is how close the p...

Hi, Does the printed core will have in your calculation take any statical load? I wonder what you want to use for the print, since all the for mortal accessable filaments seems to me too week. Also the bond between composite and print is a thing that, from what I know, none of them do realy do that....

Hi, this is not from me. i basically had that in my mind for the same reason you opened this here. Got an Alpine Access but the mast is already to wobbly, the fuse a bit too lethal and bigger wing sizes more tailored for tiny french (want a Wing&pumpfoil on the same rig for 90kg). So same thoughts o...

Very nice. Why did you mill away some foam round the insert bases? What I many time did wrong was to be too tight with resin and to aply too much pressure with the squee gee. It happend than that the cloth lost contact to the blan at uneven places (esp with handshaped surfboards) and it kind of rebo...

>>>The vac bag should have quite big "foldings" to compensate for bridging etc.<<< I agree with that. The evenly streched bag caused for me in the past quite a lot of bubbles of trapped air because the surface had slight dents. I also agree that its excess resin. Peelply helps to a certain part but ...

I fully agree with JF I bought a year ago out of curiosity a Ender 3D. 185.- does not hurt. Voice said its still good quality for low price, good comunity, lots of mods.. Since I was not sure if it really makes sence, so I did not want to jump into serious investment of a Prousa. I have no engineeri...

Hi, I guess in a day might be a bit tight. But ther are some resins that cure very fast and are, at least thats what they say, not stick anymore after 4-5 h. Check Resin Research eg at Greenlight Surfsuply or Sicomin Superfast . Prof. Surfboard builders like to have shor processes and dont want to w...

As most said, I am also convinced that it is not necessary. I think tha even the layer setup of most is exagertated if you put patches wisely. See the Gong Flint setup - Sandwich with 80gr glass inside and 200gr Carbon outside. The power distribution from the Mast is essential. I guess a broad conne...

Hi Gunnar

with the posted range of 44L, 71l, 103L, 144L and 157L I wonder where the 120 somthing L is.
With 90kg naked, 103 seems tight and 144 almost to much. It does not seem to be very even.
Are there any changes in wight ?

Cheers Dirk
