How to build a hydrofoil: Fibreglassing the Bottom Of Wings (Video 5/15)

An in-depth video series for how to build a hydrofoil from home that actually works. There are several ways to build a hydrofoil, this is simply how I like to do it. - Free Hydrofoil plans here: flukeskitesurfing.com/hydrofo...

This video:
It's time to add fibreglass and carbon fibre to the underside of the hydrofoil wings! In this video, we cover preparing the wings for fibreglass. We start by re-drilling the screw holes in the wings for later filling with resin, and then by sanding the foil wings smooth. The fibreglass layup for this hydrofoil wing starts on the underside of the wing. We laminate layers of fibreglass cloth and carbon fibre in a particular layup to support the screw connection points to the fuselage, making the wing stiff while also keeping it light. This layup of fibreglass I have done in previous hydrofoil wings and works great, providing you use a timber core as explained in the videos.

Can you make your own hydrofoil?
In my opinion, this is one of the best ways to make a hydrofoil from home. By design, the foil construction helps remove critical mistakes that people can make, leaving them with a hydrofoil that won't fly. The free hydrofoil plans are there to help you end up with a hydrofoil that works! So, If you're wondering if you can build a hydrofoil yourself DIY? You can!

This step wasn't horrible for someone with ZERO experience with fiberglass. After having to measure my epoxy by volume as opposed to weight, I regretted not spending the extra money on the Entropy resin. Luke also makes fiberglassing look sooo easy. Experience definitely helps. Also, take your time sanding so you don't burn through you sealer coat, it can be hard to tell how thick it is.

[@FlukesKitesurfing]

Yeah does take some practise :) Good points for other viewers though. Very common to oversand the sealer coat when learning :)

And don't wear your beautiful Ocean Rodeo jacket wear the worst clothing you own

My friend you must invest in a high end HEPA air purification system when doing this kind of work. Samsung AX90 would be my recommendation.

[@FlukesKitesurfing]

For sure, important to do this is a highly ventilated area.

[@ahmedehab4937]

it seems from all the vids I watched that everyone adds fiberglass and carbon fiber, why are the fiberglass and carbon fiber added, wouldn't it work fine if u just used it without adding anything? iam completely new to this btw so I may not know obvious stuff

[@FlukesKitesurfing]

You could, but eventually with wings and most importantly any connection point would fail. The foil comes under a lot of stress and force so glass is used for added strength (with a high strength to weight ratio)

[@TristramBudelcom]

Did you know you can cut carbon and also glass fiber cloth on a cheap CO2 laser in really complex shapes without any fraying

[@FlukesKitesurfing]

Yeah nice! For a project this small probably not needed though :)

[@mikenuke]

carbon is not possible i have tried. fiberglass is easy and convinient because it bonds the edge and you dont loose shape. but carbon and my 100W laser is not possible to cut through fibers.
