Hi you guys.
Live in denmark, copenhagen. Used Matts kitt’s. And the fabrics are great. Great quality and easy bonding (at the right tp)
But i have had problems with the heat sealing. But that is due to the soldering iron..
First used the Clover, but it does lack power, with some of the alterations and improvements alread described in the…[Read more]

For the maiden voyage of the V3 DIY Packraft, Nikki and I spent the weekend visiting some glaciers!

My favorite seat back, and the easiest, is a Crazy Creek folding camp chair. Not exactly a back packing item, but I can set a 2″ thick square boating flotation seat pad into the raft, top it with the crazy Creek chair and my daughter is up above the water and happy. Commercial versions that support the back and wrap around the hips are not popular among the hardcore here in Fairbanks. I bet Matt can develop something much better! The whitewater hardcore I know prefer a good kayak back band, supported with attachment loops or D-rings high on the inside of the raft. If using D-rings, they also attach their thigh braces to the same point. (I’m still looking for nice 1″ (25mm) aluminum D-rings, chrome rust, and the Titanium ones are a bit rough edged (DutchGear.com)). If using webbing one has to think through the connection so knees and back straps are connected and pulling against each other, not both building pressure on the side attachment patches in opposite directions.
Can’t wait to get my V3 built! Lets see, 1000D or 420D, that’s the question?

First Pictures of the new V3 DIY Packraft
Here are some pictures of the new V3 DIY Packraft. This one is the 120 size, and has a 420D floor (TPU on both sides) and 210D tubes. As it is now, […]-
Yes indeed!

Thanks, Rob! Yeah, the inflatable floor will be a removable insert instead of integrated into the boat – it’s just easier that way.
-
Awesome – it should be within the next week or two. Thanks!

Looks great! Wider seams, appear to be almost 40 cm wide?

Very, very nice.. Have to get me one of those..

Hi Hugh – I’ve updated the post to include the main differences. Thanks!

Thanks, Eliot!

They are heat sealed together 🙂

I’ve posted written instructions for assembling the inflation bag kit here. They are text-only, at the moment, but I will add photos and a video soon!

Got this in the mail today. Seems to be working just perfect. Test sealed 40D fabric and started with 150 C or aprox. 300 F, perfect! Now waiting for the diy-kit from Matt.

Re the leather iron from Aliexpress mentioned in Comments.
I’ve just used mine in earnest (though not on a boat, alas) and have to change my opinion. The shoe is a solid lump of alloy, yet after a few hours it bubbled! See the photo. It looked like a chrome plating with bubbles, but after taking it all apart it is actually solid. The bottom of…[Read more]

I also recommend putting a piece of teflon, parchment paper, or tape between the wire and the red guard. It helps ensure the wire doesn’t melt through the guard. Here is a picture of a teflon guard over the top screw. Yes, if it gets too close the masking tape scorches.

It is easy to adjust the temperature on a Top Flight model aircraft heat sealing iron. I suspect the other brand irons can be adjusted too, if needed.
When I got mine, it heated to about 198 degrees C (according to my innexpensive infrared thermometer – an oven meat thermometer works just as well). It was not hot hot enough to seal TPU fabric, a…[Read more]

I recommend everyone reinforce their Clover Iron before first use! I loved Chris Christy’s solution, above, but couldn’t find a 1/2″x 13 “Tee” nut. I bought some aluminum round stock to toss onto the lathe to make a supply for our classes, but after thinking about how much work was involved, I “discovered” 4 inches of thin steel wire proved to be…[Read more]

Yes, that could work for the V2 plans if you extend the tube pieces slightly (so the ends overlap enough to bond them together).

Would not say that the textile was the easiest fabric to work with, but doable. I recommend other fabric supplier if you have another choice of supplier. Have not tested Matt’s fabric so cant say much about it more than what others have written/said.
