I see, well then I’m afraid I can’t hep you 
I’m sure somebody is here in this forum who can help 
Or do you know a prog that can “clean” all the triangles 
As far as cleaning up surfaces, I have heard good things about MeshLab, but never used it myself. Its is free to download and use.
You want to “clean” the triangle on the surface ? Bad idea I think. That’s why there are different file format like step.
You may find an online file converter for ur file extension to .step. Pretty sure someone did it already.
I was mostly curious because I got some aluminum scraps and was going to mill a slingshot mast base for fun 
Maybe a prop next!

which cnc you will use for this, could share some info/pics maybe?
Had the build go against me so I have it on hold. Id say mast will flex!

Did you put in the tubes?
The gong mount hole pattern isn’t correct. The inner pairs of holes is in reality placed slightly inwards compared to the other 4 holes
Gong 2020 plate, supposed to be 90x165mm screw spacing and no fancy holes in the middle like the previous model.

I got mine in july 2020, probably old stock 2019 still delivered (if that’s 2020 model)
Hi, new in this forum. I need to adapt a F-One hybrid mast to a Nobile Zen fuselage. The Nobile fuselage has a pocket for the mast. Its dimensions are: L 110 mm, W 15.5mm. Starting from the leading edge, the first M8 bolt is at 20mm and the second at 70mm (50mm spacing). Hope this data contributes to the database
I need to know the position of the 2 M6 bolts on the f-one mast please.
Thanks
F-One gear has a solid reputation in any foil activity (kite, wind, surf, sup, wing, wake) but pretty rare on this forum (price reason probably) : there is @blocoloco using a F-One alu mast here and it is not necessarily the mast you’re after.
Unless sbdy here is already using this alu mast and would like to post a couple of picts with caliper measurements, you’ll have to find one by yourself and provide your own displays.
Then for the adaptor design strictly speaking, there are a few existing threads like this one not dedicated to the Gong fuselage:
Thank you very much. I already have the mast but don’t like to cut it to see inside. in case there is no match between bolts placement… Do you think it’s going to be strong enough just cutting the carbon part of the fuselage where the mast begins and drilling and tapering plus adding stainless steel threaded inserts? sorry for my bad english
Unless it is a minor mod, a carbon fuselage shouldn’t be cut/milled because you’re altering its mechanical properties.
It would be much safer to design an aluminium piece to insert between mast and fuselage. Usually, a new Gong mast is cheaper than this part … 
Are you sure the Nobile fuselage is made of carbon ? I thought Nobile only used aluminium in which case it could be milled like here:
You’ll have to create a new thread.
Post pics of the mast and fuselage please.
I couldn’t find a dxf of the slingshot mast profile, so here is a quick version I drew up if anyone needs it.

Did someone have CAD Data from a 90cm Zeeko mast?
Thanxs
Does anyone have an opinion about NAISH TRUST ( 2019 ) foil in size L with matt 70?
Is it a good model for electric foil?
And is there CAD data for the mast?
Thanks
