finfoil.io Designer software review

I recently got an opportunity to try this application from the designer Hans Robeers. Normally I design using openSCAD and although I have an infinite amount of control it's a somewhat laborious process involving setting maths formulae, some trial and error and making new formulae when I want to mak...

Re: Covid vaccine

23 now? Was 13 when I last saw that article a few days ago. Out of 30,000 or so vaccinations, so my math makes that 7/10,000 and doesn't that make it more deadly than the virus itself? Absolutely not. Covid-19 case fatality by age is approx 15% for over 80 year olds. Actuaral average expected remai...

Re: Covid vaccine

I think some anti-vaxers on here are paying more attention to Q Anon conspiracy theories about 5G, deep state, Trump "as a hero" and antifa as THE ENEMY than covid-19's promiscousity and clingy willingness to turn lungs into a pnumonia breeding ground and our blood vessels into sewerage systems. Mir...

Re: Building a super low aspect ratio high chord unifoil.

On call for a week with lots of wind! :x However on call is always a great time to catch up on projects. I bought a 30m roll of 4 ounce surfboard glass fibre.

Re: Obsession for beginners, is that bad?

I don't have that kite and I'm not a freeride style kiter but I do have one, a 5 line switchkites freeride one from a few years back. It's not my favorite because I can jump higher with the Nitro.

Re: Wing profile info for backyard hydrofoil builders

I have studied how to upgrade my Ender 3 to print polycarbonate, and this does not seem like too difficult of a task. Plus lots of success stories of others printing polycarbonate with, so I have good confidence that I can make it work. True, the structural integrity is an issue: the Javelin hydrof...

Re: Inflatable Boards for Winging

Those samples were part of a research project done by a Technical university and a dropstirch manufacturer (name was not disclosed). What dropstirch shape are you after... just shaped and stiffer rails? There are other ways to get it done at DIY level, but it's a hassle! I can add my own rails, no ...
