    I received an assortment of adapters with a new Flextail pump I got through Aliexpress. I took apart another boston valve and just attached it so I can screw this in to my raft when it’s time to inflate. Need to be a bit fast when it’s done to swap out the valve insert, but it allows for no hands inflation.

    I finished up my Skeena build much more quickly than the Atlin. Probably about 20 hours or so. Second time through was much easier. I went for a simple, small boat this time and omitted the TZip. I really like the color!

    I figured having a second boat would be helpful if I wanted to bring a friend with. Also I joked with some canoe friends of…[Read more]

    Simple new project for today. Used 250GSM fabric to make a phone pouch for an Anfibio inflatable lifejacket.

     

    Sits inside the chest area, velcro closure with webbing pull handles.

    Above is a new roll of that UHMWPE thread I like.

    Nice. Have you tried to see if your adapter will friction fit tight enough to leave it until it’s full? How pressured can you get the boat?

    Yup, that adapter that tapers right? lol

    Maybe I need to take the rubber off. I find that it stays in for a little bit, but once the pressure becomes higher, it pops out. I still have to fill it for another 30 seconds by breathing into it.

      That’s really cool. I need to come up with an adapter that functions the same way for my pump but also supports the top-up valve.

      Dwayne replied 1 year, 7 months ago

      I found this 3d printed adapter posted on Printables.com. It is a perfect fit for the boston valve and, with a slight internal diameter adjustment, will fit snugly over the top-up inflation stems for the backrest and seat.

      Derrick replied 1 year, 6 months ago

      If I understand correctly, cutting the Boston valve isn’t necessary. You just need a flange on the inflation bag and put a valve piece between the inflation bag flange and the packraft flange. This should work because I think flanges can be screwed to both ends of the value (with the cap open obviously). You can use a valve with the rubber bit removed to quickly inflate the packraft then switch to a valve with the rubber bit still there to top up the with the inflation bag (no longer needing to top off with your lungs). Is this correct? Is that how you have been using it? I’m considering getting another Boston valve for my inflation bag to try it out. Does it work well?

      • Profile picture of Matt (Admin)
        Matt (Admin) replied 1 year, 6 months ago

        Haha, I never thought of that, but you’re absolutely right – you could just iron the flange to the bag.

        You might be able to screw the inflation bag flange onto the boat’s check valve after it’s screwed in for the final top-up… yes, I do think that would work. The downside is that screwing the bag on and off would almost certainly take longer than using your mouth for those last five or six breaths. It’s possible you could get a higher air pressure in the packraft using the bag, but because the threads aren’t a perfect match between the flange and the top side of the check valve, I’d be careful to avoid damaging them by trying to force a lot of air in.

        I actually haven’t tried the valve-in-the-bag method myself, so if you test this before I get to it, please let us know how it works out!

    I’m kind of new to the inflatables world, but just finished a Telkwa recently. It was a fun experience, but I decided I probably won’t build another kit anytime soon due to the time it takes and attention away from my wife and kids. I recently discovered online, however, that NRS used to build a whitewater inflatable kayak out of TPU in the Bandit…[Read more]

    krafter replied to the topic DIY Accessories in the forum DIY Packrafts 1 year, 8 months ago

    That’s the solution I proposed in my previous post, but that’s what I’m saying – if you split this into two pieces you might as well carry the adapter that came with the pump, which will be lighter in total

  • Profile picture of krafter

    krafter replied to the topic DIY Accessories in the forum DIY Packrafts 1 year, 8 months ago

    I see this, but the tightness of the fit should already work for hands free operation. I based the dimensions off the flextail adapter for Boston valves, which is the one with the the little rubber attachment – if you pull that off you’ll find that the little plastic piece left over fits perfectly onto the valve.

    Hey Krafter, have you seen the screw-on adapter shown here? Merging your design with the Boston Valve screw-on on threads would allow hands-free operation.

    I was initially thinking about trying to figure this out, but I was a little DIYed out and just bought one from MRS. Not sure how well it’ll work, but I’ll report back. I’ve found almost all of my leaks and fixed them but I’m still finding I need about 5-10 breaths per hour. If something like this ends up on the store, I bet it’d be pretty…[Read more]
