Jamie started the topic Inflation bag – update in the forum DIY Packrafts 8 years, 7 months ago
I’ve been playing around with different materials for a way to secure the inflation bag to a Boston valve. The best material I have found is some plastic from a spiral bound folder. It is flexible but fairly rigid, and virtually in breakable. With the hole cut to the right diameter, it just pushes over the thread of the Boston valve without…[Read more] -

Several people have asked for details about the new ultralight 40D ripstop heat sealable fabric available in the shop. At 100 grams per square meter (3 ounces per square yard), it’s very lightweight and packs down […]

Matt: Thank you! I am one of those awaiting your input on this. I look forward to the video.
How does it compare to the red 40D taffeta? I will know soon enough as I ordered some a week ago but I would like your take on it as well. As always, I appreciate your efforts. Ron Samber-
Hi Ron – the older high threadcount 40D taffeta was about twice as heavy as this new stuff, but it wasn’t twice as strong, so as far as weight vs. strength goes, I think this is a better option for ultralight applications.

Yes, that’s right 🙂

Interesting… Yeah, I know of a couple of people who have tried using Cuben fiber and tape for inflatables, and the problem with the tape is that it migrates over time under pressure and eventually the seams pull apart (in a packraft, anyway – it seems to work fine for other applications where there’s less tension on the seams). It’s also prone to punctures, as you mentioned. The Porcher fabric sounds interesting, but I guess it would have to be sewn and taped.

I’m not sure, but regardless, I always recommend purchasing a fabric sample pack so you can compare fabrics directly.

Thanks to Steven S. for sending a link to this inexpensive rheostat. It might be helpful for those using a regular (non-adjustable) soldering iron as their heat-sealing iron because it would allow them to dial in the perfect temperature.
Due to the solid state electronics in mini irons like the Clover, I’m not sure if it would work with them, but…[Read more]

I have just added two new fabrics to the DIY Packraft Shop – 420D with TPU coatings on both sides, and 1000D with extra thick TPU coatings on both sides.
These are relatively expensive, heavier fabrics, and […]
-
It will be combined with single-sided fabrics.
-
There will be two different versions – one with a 1000D floor, and another with partial 1000D tubes as well. The price for the former will likely be similar to the current kits with double layer floors or a bit more, and the latter will be a bit more than that. The exact amounts will depend on how efficiently I can utilize the fabric. As I’ve said from the beginning, the point of the DIY Packraft project is to make packrafting more affordable.
-
What do you think about adding a layer of the new thick fabric on the inside floor of an existing packraft? Would it bond ok?
-
As long as it’s a TPU-to-TPU bond, it will work fine. Cheers

I bought my MRS from the German store and got their Anfibio paddles too. For the new DIY rafts I have paddles from celticpaddles.com in Anglesey – they make a series specifically for packrafts, and these look the cat’s whiskers.

Just wondering what paddles are recommended for the DIY packrafts?
thanks.

I was thinking of using plastic D-rings instead of a loop made of webbing. These could be secured to the packraft in a similar way to the above.

Matt (Admin) replied to the topic Self-bailing floor? in the forum DIY Packrafts 8 years, 7 months ago
Hi Jim,
My recommendation is to install a couple of these valves in the floor, at the sides near the rear, where they won’t be covered by your seat. When the valves are open, the packraft is self-bailing, and when they’re closed (on flat water) it’s dryer and lighter (because you’re not hauling water in the boat).
You could also model a…[Read more]

Matt (Admin) replied to the topic Inflation bag in the forum DIY Packrafts 8 years, 7 months ago
This is a great idea!
I’ll tinker with it a bit myself using 40D ripstop instead of Cuben.
Thanks, Jamie!

Hi
Here’s a suggestion for an inflation bag that I’m working on. The bag is made out of cuben fibre (this stuff is expensive but super light and strong; I had a rectangular scrap left over from a previous project). The valve solution I have come up with is this: a rubber disc/washer about 2mm thick, with the diameter of the hole roughly 20mm, and…[Read more]

New guy here, no robot.
Just looking through the site and like the design. Years back I used to pack cheap store bought heavy one man rafts into the Windriver mountains and now my older back needs to go as light as possible.

Hi,
Just purchased my first packraft from this site and was wondering if anyone had any recommendations for an iron in the UK.
Thanks in advance

Jim Yeo started the topic Self-bailing floor? in the forum DIY Packrafts 8 years, 7 months ago
Has anybody thought up a self-bailing floor design? I got to thinking about it after reading about the inflatable floor option. Obviously it increases the potential for a wet butt, and perhaps more weight, but I’m curious about the possibilities.
