Surprisingly that’s not it – this is the one:

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

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.

I’m still building my packraft -…[Read more]

The windows aren’t the real problem – you can close them with your fingers in a pinch.

The problem is that the pins on the end don’t allow for a mating with the other valve. The location of the holes in the Boston valve determine the inner and outer diameter of the adapter. It’s too big to fit inside the other valve and too small to fit…[Read more]

Are you talking about the backrest/seat tube-style valves or the little red tab-open valves that you see on camping pillows?

This doesn’t work with the tube-style valves because the pins get in the way; I haven’t tried the other ones, but I suspect it might work if you don’t mind where the pins end up on the other side. The one caveat is that the…[Read more]

Tested and it works well!

The pump is definitely not strong enough, and this makes it go faster I think – so both. Feel free to make a new forum post with the link!

Emails went to my spam folder :facepalm:

@UncleFred, I did print out a prototype and test it – it fits perfectly into the pump and is a tight fit on the valve as well. I messed up on the pins by heating the whole adapter at once  with a hair dryer, which caused a couple of the holes to close up. This messed up the insertion of the rest of the pins. See photos.

I fixed the design to…[Read more]

My first useful contribution here: I designed a 3d-printed adapter for the Flextail tiny pump 2x to the boston valve that can open up the check valve part and let air flow through freely. Print it with the narrow part down and the wide part up (upside down). If the flextail pumps have the same diameter output (which I suspect is true) it should…[Read more]

Placed the order for the Atlin! Thanks @BobDep for your help!

Thanks! Two more questions for you (I don’t know if you’ve tried the Skeena, but you said you’ve used other kayaks, so…) – which of these would you say is better playing the “as a” role?

a. The Atlin as a general-purpose packraft (mostly lake paddling and possibly occasional class 1-2 WW in the future, <50% bikerafting)

b. The Skeena as a…[Read more]

Thanks for the response! Do you do mostly flatwater (lakes) or rivers?

Also, do you think it works well as a general-purpose packraft? Say bikepacking < 50% of the time, future class 1/2 rapids possibly. I’m looking to use it as a raft on lakes mostly though, with or without bikes.
