How to build your own (rotomoulded) whitewater kayak

[@tylertucker2608]

This is a very interesting project! Please show us more on the roto moulding process. Nice work, it turned out great!

[@KayakBrothers]

i try to make some videos next time

[@Senders]

This is so epic!

[@williamlowry4099]

This is the coolest thing I've seen

[@shanebenedict3204]

Super cool guys! Nice work!

[@KayakBrothers]

Thanks ! We have already the next prototype on the water . this one go in the same direction like your RMX.... but we didnt steal your idea... ;)

Wenn sich das Kajak so gut fahren lässt, wie man aussieht... Echt der Hammer 🤙

[@KayakBrothers]

Wir sehen schon ziemlich gut aus, stimmt. Aber das Boot lässt noch ein mikrobisschen besser fahren.

@@KayakBrothers This is awesome, I love the hardwork you showed. How many times can you use the mold versus a steel mold, did you need a special resin to withstand the heat, not ignite. awesome job 👏

just goes to show how the big companys are ripping us off excellent work nice looking boat

[@sadder9531]

there is always a huge work in the background ... video is just nice to see but when you get your hands dirty and find out that your first try should be thrown away and to repeat to avoid mistakes you did before ... which we name experience ....

[@icast.2388]

Ekselent job!!!!! Do you mind if you share FIBERGLASS name and RESIN name? THANKS

Awesome, what kind of filler did you use to shape your design ?

[@guachingman]

Do you fill the void inside with foam? Would it make a difference, float more? Amazing craftmanship btw.

[@martini7454]

Air floats. Foam only traps air bubbles, and thus floats less than air given it's weight. So adding foam would only add weight. However, if a kayaker swims out of their kayak and the boat fills with water, having something to displace water helps keep the kayak floating. This brings us to float bags. Some kayakers will add 'float bags' which are just plastic/rubber bags of air that *displace* water if the kayaker swims out of the boat. You can google 'kayak float bag' for images. Cheers! :)

[@RonnGarris]

what kind of filler did you use to shape your design? Also, do you know what temperature your furnace was at when you molded it?

[@RonnGarris]

@@KayakBrothers very interesting! I’m actually in the middle of designing and molding a kayak of my own. I have a ton of questions. Mainly, how difficult was it to remove the top mold from the cockpit rim? Did you have to cut the mold to free the boat?

[@stephenburden8947]

Currently working with my brother on designing and building a rotomold and designing a new boat. Glad to see your video and know that other people are doing this too!

[@manimanason2094]

how much plastic did you use for one boat

[@KayakBrothers]

15-17kg of plastic. how you like

[@777PLove]

thank you for inspiration

[@KayakBrothers]

Thanka. Watch our leatest video ;)

@@KayakBrothersI have been checking out your channel good stuff that's coming from a video kayaker if your ever round the Gauley River look me up be good too meet youons

[@simonsimon405]

how does the top part mold is removed with the negative angle around the skirt groove?

[@KayakBrothers]

We have 3 Parts of the mould, but you have to destroy the foam shape. For the PE kayaks you haven't any problem when it's warm enough.

[@agamtea82]

@@KayakBrothers What type of resin do you use for the concrete you use, is it FRP? Thanks

[@KayakBrothers]

@@agamtea82 Sorry but that's a little secret.. but you can use different types of resin.

[@FrankensteinDIYkayak]

yeh you can do it thatway but there are others as well and much less time consuming. with the huge number of cracked and wornout whitewater kayaks around you are better off getting a hot air plastic welder and going the frankenstein method.

[@kayakcroatia]

Awesome. I want to make my own kayak but out of kevlar or carbon... neber occured to me that i could rotomold it. Hmmm can you really heat up the mould made from glass fibers and epoxi resin? What did you use for plastic ? Seems like a lot of work. Good job guys. And how many kayaks can you make out of that mould ?

[@kayakcroatia]

@@KayakBrothers thanks for response. I meant to ask where did you get plastic from ?
