Forged Carbon Mast Adapter

Hi All,

Forged carbon fiber mast adapter:

I was looking to make a foil tuttle adapter for a custom carbon foil to my gong v2 mast and thankfully came across this file from a previous post:

I thought it might be interesting to try to make that part using the forged carbon fiber process outlined here: Forged Carbon Fibre Mould Design and Strength Optimisation - Easy Composites

After a month of learning Freecad, coming from Fusion-360, the mold came out great!

I used bolts(not shown) and stainless shafts(x3) to hold the mold together and create the through holes during the forging process.


I then applied PVA, carefully measured my carbon and epoxy ratios from the guide above and clamped everything up with aluminum backing plates.

The results:



The final adapter part weighs ~100g compared to the original part which weighed ~200g and the adapter has caused no signs of corrosion on my mast because I sanded/coated with epoxy.
I’ve tested this part for 2 months so far without any failures or further notes on performance.

Contact me if you’d like access to the files!

It looks really nice!
Did the adapter fit, or did you need to do a lot of sanding?

It was probably 5 minutes with a de-burring tool and an hour with some sandpaper, not too bad. I made it fit a little tighter than the stock version and now I just pop off my fuselage from the tuttle mount when I’m done foiling to fit it in the car.

It’s important to stick to the high infill on the 3d printed mold to avoid warping on the part when final shaping. It’s a repeatable process though, I made a 2nd one for a friend who was kind enough to give me a new front wing.
