Towards the end of 2021, I decided to build a 3rd efoil.
This time shouldn’t be based on an inflatable, but on a wingfoil board.
I quickly found what I was looking for at Gong and bought an almost new Gong Lethal 4.10 80l at a good price.
This time I decided to use an FR motor.
For the engine control I take a A200S V3 VESC.
In my first and second project, I have had good experiences with Gong foils. That’s why I’m sticking with this system.
As mast i will this time the V2 85cm CFK.
For the batteries i will use LG-Chem Li-Ion Zelle 3.65V / 51Ah / 180Wh.
At moment i had maximum less time, so i think my build will not finish this year.
No, not was so easy but in some hours possible.
Inside the CFK mast is a foam core but interspersed with some longitudinal ribs.
I bought the Wingfoilboard used for less money
Next steps are done.
I thought about using the original Mastclamp from FR or construct / build an own one.
I decide me for DIY.
I constructed in Fusion 360 my Mastclamps.
Is the SLS material you chose nylon 12 or nylon 11? I ask since LS nylon 12 prints with some porosity and may not be water-tight straight off the printer. Regardless I would suggest sealing it.
I not will print theme with an FDM printer.
It is only a prototype for playing.
My plan is to print the side with the pins in my SLA printer and use a strong and flexible resin.
The other side I will print in Strong X resin.
After a long time, I took some time today to get on with my project.
I sandblasted the aluminum mast clamps first, then cleaned them and prepared them in anodizing activator.
After rinsing, I immediately placed them in an anodizing electrolyte bath and anodized them for about an hour.
After rinsing again, they are dyed.
I’m looking forward to the result.
And now the result. It’s ok for my first try. Unfortunately, when I fixed and closed the pores, the water evaporated too quickly. That’s why you see this small island on the mast clamp.
I’d like to try some anodising.
