Great video! 👏 I really enjoyed watching the DIY barrel pontoon boat part 1. It would be awesome to see a follow-up or update video. I'm curious if there are any new improvements or changes. Looking forward to more content! Keep up the fantastic work! 🚤🔧
Excellent build although I think you need to get a motor controller that can pull from both battery and solar Maybe a vawt turbine I plan to make a similar boat but I'm going with 3 hulls. 2 hulls like yours but bit further apart then a central hull that's half a foot deeper into the water than the other 2 to help add stability. Probably will either use plywood and fibregass to make walls or use bedsheets/blankets and coat them with LineX. Make a little cockpit/sleeping area. I've got two 200w flexi panels for the roof and will definitely look at vawt turbine options
you got another subscriber bro. This was an amazing video and as you were going through the design its 1/1 idea of something that ive been brewing on paper but havnt tried. Thank you for sharing! if i had the means i would donate but i work with recycled materials and do everything without charge.
UV rotted the ropes off my 7’ x 14’ raft with 10/ 30 gal. drums in 3 years. Next time I’d use galvanized pallet strapping. Our drums don’t have a groove at the bottom to locate (house v.)the ties.
Lucky you. No groves makes it more hydrodynamic. These plastic ropes are being used everywhere here on Sumatra. UV will kill them but I am sure I get minimum 6 years out of it.
Can't hide my German accent it seems :) But thanks. I hope that answers some questions for some newcomer barrel boat builders :) Bist du gerade am planen eines zu bauen?
Before you put the steel on the joined sides of the bow part, did you fully heat seal all of the plastic seam? The inside PU foam is for adding flotation, approximately what percent of the volume does the foam and the bottles take up and does the foam take a semipermanent bond to the inside or can we expect that it will eventually work free? Nice informative video.
Heat sealing would be the best option (instead of my foam sandwich solution) but I did not do any heat sealing. If you want to heat seal HDPE (High density polyurethane) you need a big hot iron and heat up both sides simultaneously which i don't have. Blow torch doesn't work. But the foam seems to be waterproof till now. I put the bottles inside just incase water will enter the drum. The PU foam is mainly there to keep the bottles together. So in case the drum fills with water. The bottles won't float on top. If something works free or how long all that will last needs to be found out. The boat is in the water since a few weeks without issues. But let's see what the future brings :)
@@bgradediy5267 Thanks for the reply. I see your points. I've seen other videos where people are using repurposed electric ovens, heat guns, etc. to achieve heat sealing. Keep posting your results and progress. The PU foam seems to do what you expect with far less hassle. The tipping point of using heat seems to be a fine line between sealing and destruction of the material, indicating that it's more of a "laboratory controlled conditions" sort of thing. Thanks again and good luck! ⭕
Was outside the country for a while. But going back soon and start building within the next month or so. With another quick video if i am not too lazy :)
FYI: I learned later on that you can melt it together with a big hot iron. Instead of using the black foam. Never tried yet. But might be a better option. Haven't even realized i was barefoot till now. :)
@@0xKruzr These drums are made from HDPE. Which can't be glued and very difficult to "melt" together. You need a big hot iron between the sides. Heating it up with a gas torch won't do the job. I tried.
@@0xKruzr They use these things for HDPE pipes: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ul0nub5m8lQ.html I guess two irons (for cloths) can do it somehow? I am just thinking out loud here :)
This is PU Foam. Normally sold in sprays used in construction sights. But you can also just buy the ingrediencies and mix it yourself. 1Kg cost here in Indonesia around 7 USD. Like this one: www.tokopedia.com/berkahutamashop-1/polyurethane-foam-a-b-pu-cair-rigid-500-gram
Magnetic fields are static. So as long the magnet stands still and doesn't move around the electronics there should be no interference. And after years of using this sensor. I can't recall any problems so far :)
