• Hi all,

    I’m planning to add a zip to my Yak, and wondering what everyone else is using for inner gear bags?

    My head at the moment is tending towards 2 cheap lightweight pack liner drybags, and gluing a tiedown/clip to each of them to secure inside the tubes like the real ones. The bags will be way fatter than necessary, but not sure if that’s a…[Read more]

    Some time ago I posted a page about making your own inflation bag*, and since then several people have asked me to supply parts so they won’t have to spend time and money sourcing them elsewhere.

    In response, […]

      I am especially interested in your connector that fits the fine Boston Valves. They are great valves, but an odd thread I have not been able to successfully fashion on my lathe. Worth the price of a kit, though I made my bag out of silnyl not TPU.

      • Hi Bruce – the connector is unthreaded silicone hose, which is soft enough to screw into the Boston valve’s unusual threads without damaging them, and there’s no risk of cross-threading. The size fits the larger (drain) part of the valve, which makes inflation muchfaster than forcing air through the check valve part of the Boston valve. Once the packraft is full, I pop off the inflation bag, screw in the check valve, and top off the air pressure through the check valve by mouth. The whole process takes under three minutes.

        I’m a fan of silnylon too, but keeping with my no-sewing promise I’m sticking with TPU (though Cuben fiber/Dyneema would also work well).

          Great, I can find silicone tubing online. Did you use 20mm ID x 25mm OD size tubing? (The next size smaller is 16mm ID x 20mm OD, while other suppliers offer fractional inch measurements up to 7/8 inch but I think that’s too small.

    I’ve just finished writing up instructions for the new seat kits, and they’re posted here!

    Awesome! Thanks for posting, Dave! It looks great 😀

  • Dave replied to the topic DIY Packraft Photos in the forum DIY Packrafts 9 years ago

    Very happy to show off the newly completed packraft, as you can see using the new green fabric! I tested it out yesterday and it worked very well. It’s impressive how lightweight yet rugged these craft are.

    I still plan to install a top-up valve, and multiple tie downs for a packtach system.

    My only issue now is in trying to fix a slow leak.…[Read more]

  • Hello! I’m Torgil from Sweden, just registered to the forum but I’ve been lurking this fantastic site pretty much since it went up.

    I’m planning to do a build this coming winter so I thought I’d register so I can tap the resources here.

    Bottle top valve installed in a seat. Some bottle tops (like this one from a Badoit sparkling water bottle) have a slightly lower profile. The valve is absolutely airtight without the screw top on, but deflates easily when the flap is pushed in with a finger tip. Works better than I thought. No going back now – I prefer this to the Boston valves…[Read more]

    Hopefully I didn’t cause too much alarm with my question.  In my tests the minor stuff didn’t seem to leak, but a couple of the more majorly damaged areas did. When I say “leak”, the area appeared damp on the outside after a couple of minutes and then a bead slowly formed.

    Probably I should explain how I did my tests. I took some scrap material…[Read more]

    Hi Matt,

    Thanks for the reply.

    I think Dave meant (correct me if I’m wrong Dave) that only the TPU coating was damaged i.e. the fabric and underlying PU coating were in tact.

    I’m using a temperature controlled iron, so I don’t have any issues with melting the fabric itself. Only the TPU coating melts when I place my iron on it, and this is…[Read more]

  • Matt (Admin) replied to the topic What paddles? in the forum DIY Packrafts 9 years, 1 month ago

    I’m currently using a very light two piece carbon kayak paddle made by Werner, which was a very generous gift; if you’re making or purchasing a paddle, I recommend choosing a four piece design because it’s easier to pack.

    When it comes to paddles, spending more money generally gets you a lighter, stiffer paddle. Depending on the type of paddling…[Read more]

    Same thing happened to me as Chris Chitty above with the Clover II from Amazon US — Mine was hot enough but after a few uses the heating element broke off from the handle because of the poor construction of the mount. I’m looking into modifying my soldering iron now.

  • Jamie replied to the topic Valve hack in the forum DIY Packrafts 9 years, 1 month ago

    Also a  good light weight valve for the seat or inflatable floor, with the added benefit of the inflation bag adapter (mentioned earlier) fitting all valves.

  • Jamie started the topic Valve hack in the forum DIY Packrafts 9 years, 1 month ago

    Here’s an alternative to a Boston valve. Works well with the inflation bag adapter (see my earlier post). Good airflow, and the valve creates an airtight seal. Only weighs 11g.

    Cut the top off a carbonated drinks bottle, just below the flange. Sand the bottom flat.

     

    Sandwich between a couple of discs of nylon with TPU coating on both sides,…[Read more]
