After becoming disillusioned with my broken down sealing tools, I sat and watched youtube videos on hot air welding guns and then went and bought
 this one from ebay.

I’ve only had it a couple of days and only played briefly with it, but I’m very impressed. It comes with various bits including a 20mm flat nozzle and a silicone roller, is nicely…[Read more]

My packraft has a lot of leaks from incompletely sealed seams.
Probably I think that the form of the bowl when heat seal iron does a curve was bad.
Therefore the seems of the curve is not beautiful. Air seems to leak from there.
When you made PACKRAFT for the first time, were there a lot of leaks from incompletely sealed seams? Will such a th…[Read more]

Hi @hiroshi – well done! It looks good, but still a bit soft.

Another method of finding leaks is to put some air into the packraft and submerge it in a bathtub or lake and then squeeze it – air bubbles will escape anywhere there is a leak.

If you are experiencing lots of leaks from incompletely sealed seams (not punctures), it might be a good…[Read more]

Yep, you can definitely add a layer of fabric anywhere with my design, which would double the strength. I’m working on getting heavier fabrics, but can’t promise a release date yet.

It was completed.

However, there are many punctures.
I must solve this puncture.
I attach soapy water and find the place of the puncture and intend to heat-seal it.
Because there are very many punctures, is there the method that, besides, is good?

If you create a Packraft with the T-zipper you can insert airtight chambers with your gear then you have a multi chamber Packraft…

The only way to create a rigged 2 persons Packraft is using the High-pressure Drop Stitch Floor or aluminum Poles (construction)… 😉

The tubes folding up was an issue even in flat water, and I imagine that in broken water it might well get swamped. Part of the trouble with the MRS X2 is that it doesn’t have a top-up valve usable while paddling – you have to pull up on the bank to top up the pressure. If I were to keep the boat I would definitely add one and that would partly,…[Read more]

Welcome to the forum, Jeb!

I’ve been working on a two-person packraft design for a while now, but I’d like to avoid the floppy side-tube syndrome that people complain about in the manufactured two-person packrafts. How much of an issue was this for you, @lynsg? I know you found the length an issue for comfort as well (it not really being long…[Read more]

Haha yeah – nothing is actually copied and pasted, but so far it doesn’t look like this Nick Kowalski character has anything new to offer, aside from his location.

As far as I can tell he hasn’t even built a packraft yet, which makes his “Iron Raft” venture quite a bold move… unless he’s selling someone else’s proven design.

A two person boat plan and/or kit would be phenomenal.  Something similar to the Explorer 42 perhaps..  I think the boat plans are probably the most helpful for folks, once one learns how to assemble them, they can come up with their own accessories.  Getting the patterns for a new boat design would be a lot harder.

Inflatable PFD would be pr…[Read more]

Rather more than imitation, it looks almost like a straight rip-off. A whois shows the site was registered on 5.01.2017 by a Nick Kowalski in Somerset. The videos and instructions are “available after purchase of a kit” – why are these not public??? He will sell you a sample pack of red, blue and black fabrics, but only sells the kit in green.…[Read more]

They say imitation is the sincerest form of flattery… check out this copycat DIY Packraft shop – they even call their product a DIY Packraft Kit 😀

“iron raft“

What I really would like to see would be a multi chamber one with a spray skirt for whitewater and an inflatable backrest. Another thing that would be nice would be a self bailing one that you don’t have to sit in a few inches of water.

I heated up again.
I was able to tear it off.
Thank you.
