Re: Who uses a cnc for their builds

Have a look at EstlCam. It´s easy to use and quite cheap. There is a lot of online support on forums/facebook groups for it. link: www.estlcam.de There are also some free CNC-controllers like GRBL which also works with an Arduino. Micha Hi Mica, some cuts from your original post but just giving a d...

Re: Cabrinha X2 wing

<cut> Yes, I work for Cabrinha, but all our feedback has been about how locked in the draft is and amount of low end power this generates all due to the exclusive stacked double boom tech we are using. The great thing is that together with our extra long handles, you can get the stiffness of an act...

Re: Open Fuse

<cut> For big wings and rider wight I would also opt more for 3mm through out the fuse and solid around the cup. I have been trying arround with carbon tubes for that that had 2mm wall thinckness. The might seem stiff enough but seem still very fragile. If you have unwanted ground contact tha cause...

Re: recomendations impact vest (with a bit of a rant)

I've got a jetpilot X1 series. About 4 years old now and Looking like that, I kite through winter too when I get the chance. Now learning wing foiling and I put my key on a fishing clip/swivel around the shoulder strap, it guarantees I put the vest on! Also, I can bend sideways and operate the key i...

Re: Winging is half-assed kite foiling - discuss

I'm right at that very early learning stage. For me it's the joy of a new challenge, solving new problems I've never dealt with before. Building new muscle memory, new physics understandings. Incentive to loose weight and something new to keep me motivated to do it. That said, I fully understand on ...

Re: Open Fuse

Update: added the first free design CNC wing with cutout for Gong or open fuse. Needs the fuse to be wrapped with packing tape, several layers of braid fitted around and then inserted into the cutout and aligned while composites are fitted, infused and cured. This is a massive learner and/or low win...

Re: wing sup surf - without foil

You need height to lift the wingtip from the water and you need to be up on the foil to reduce the drag and lessen the effort of holding the wing. But a small wing on a SUP with a centreboard just to minimise paddling is do-able. Or for downwind.

Re: Mast position - explain like I am 5

I haven't been down your learning path but how fast is the boat towing you? I think you want it moving only just fast enough that you can press down with your back foot and start climbing out of the water. With a big foil this is barely jogging speed.

Re: Open Fuse

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...

Re: Open Fuse

12mm fibreflass rod... Thats gonna be a pretty wobbly ride I think. And the glass rod is usually pultruded, so only unidirectional fibres, very very flexible tortionally. That stab is gonna be wobling around a lot. Might be a good idea if make a low effort prototype first, like chop a aluminium fus...
