In this case, I think I would heat seal them in place as best as possible and add Aquaseal where necessary, and then reinforce the joint with an additional strip of fabric heat sealed on the outside of the packraft (overlapping the joint between the tube and the floor). I’d add the reinforcing strip after the seam strips were in place joining the…[Read more]

Hello From Fairbanks AK, I just finished my raft!

The long seams were tricky trying to reach inside those tubes.  If I remember right, my floor is 84″ long.  I’d say think it through before you proceed so you are sure you’ll be able to effectively seal those long seams from the extended tubes.  I had some persistent leaks there that I finally sorted out.

Don’t mess with the 3m stuff, I just us…[Read more]

Hey Derek,

Great build. I’m actually just starting on building my own plus-size voyageur, but even larger to accommodate two kids (about 100″ long).

Any other general tips you want to share? It sounds like sealing that inside tube seam during construction might be a good approach. I have loads of Aquaseal but none of the 3M stuff you…[Read more]

I just made my first purchase and i am pumped!!

Hi!!!

I tried several different heat sealing tapes. Bonds to the PU coating was unsatisfactory so I gave up. I was also unable to determine if the film of tape chemically matched the TPU coating. My understanding is that plastic welding and bonding only works between two identical or compatible plastics.

Great to know the Big Agnes fits my Voyager. An interesting complaint packrafters made about using their camping pads for the floor of their packraft was sleeping on a wet pad. A solution is to put the pad under the tent floor!

I’m fascinated with your successful application of 3m 5200. I bought the slow sure version and had no luck getting it to cure. Great looking craft, love the photos!

Marcin, Yes, packraft inflation is limited to lung pressure, at or less than one psi. In contrast, I believe a full size NRS 18′ heavy duty raft is inflated to 2.5 psi, much higher pressure than any packraft should be inflated.

It is an interesting question, and I have just acquired a low pressure gauge to fit my NRS barrel pump so I can pressure…[Read more]

1. I estimate the air volume to ca 5-6 liters,  so around 50-60N boyancy. The straps are sewn on to a piece of 1000D tpu, sandwiched between the 210D main tpu fabric.

I am on holiday now, but I can find the plans when I come home.

Hi

I have two qustions, maybe three:

– What is buyonancy of that vest? Did you test is?

– How straps attached? Glues or sewed?

– Have you got any drawing? Plans?

Right now I try to make something similar. Have to reduce places in rucksack, and two standard PFD take about 10 liters of volume.
