At least she is sea worthy! I still need to create a spray deck, inflatable floor, and some tie down points, but I couldn’t pass up the nice weather and the opportunity to take out the raft.
What an awesome raft, and fun project. Thanks a ton Matt! Also feel free to use these pictures elsewhere.

Logan replied to the topic Help & Questions re: DIY Packraft Construction in the forum DIY Packrafts 8 years, 4 months ago
Ok, packraft is complete! I’ll post up pictures in a bit. Short Answer, this error I made in construction caused no noticeable difference. I can’t even see any wrinkles on that seam. Turns out I had my iron a tad bit too hot which caused some wrinkling leading to the shorter piece. All I did to fix this was cut the floor to match where the tube…[Read more]

Added a few tie down points:
one inside on the floor with a paracord loop to clip a nalgene onto: It’s simply 2 – 2″ circles of 210D with a 1000D semicircle in between.

Then 4 on the bow for a grab line (using the improved tie-down method posted here on the board):



And then took it for a test drive in grandmas pool:

Feel free to use anything I post here 🙂 I’ll take some good measurements of things tonight and post up more information and details. The measurements you provided for the TIzip location worked out beautifully.

I say it’s finished… but I feel like a project like this is never done… it’ll continually change to meet my needs. But for now it holds air so I’m considering it finished enough until I actually get around to using it this summer and figuring out my first round of modifications.

Things I learned:
Don’t use the Coverite 21st Century Iron.…[Read more]

@lynsg
Lyn, I am curious as to how you pre weld your seams before you use a heat gun on the seams! Do you first. Weld them with a mini Iron over a curved surface then go over the whole tube seam again with the gun and roller?
Thanks.
-Maynard--
I weld them with a Jingda iron, but just by laying the tube pieces flat and facing together. Imagine that you’re sewing the pieces together, so you add a seam allowance of 7 mm or so to each end of each tube piece and then, instead of sewing, you weld them on that seam allowance. This is where Alpacka sew theirs. You end up with a hull that’s…[Read more]

Hi Matt,
Thanks for your reply, I didn’t think to check the MSDS.
The main glue listed in that forum is no longer available. I did check the local hardware store and found the product Sika Bond, Tech grip. This is a high strength Polyurethane adhesive and it contains …….4,4′-Mthylenediphenyl disocynate…Ta Da…

I’ve uploaded a new video showing the V3 DIY Packraft construction process for those who have purchased a kit. The video password is the same as the password for the rest of the instructions. Have a look!

Matt (Admin) replied to the topic Seamgrip vs Aquaseal in the forum DIY Packrafts 8 years, 4 months ago
Hi @stevoggo – I checked the MSDS for Aquaseal and it looks like the main ingredient is 4,4′-methylenediphenyl diisocyanate, with toluene as a solvent. Shoe Goo is tetrachloroethylene and styrene, 1,3-butadiene polymer. So, not the same thing, but that doesn’t necessarily mean it won’t work just as well – the only way to know for sure would be to…[Read more]

Hi all,
Wondering if anyone knows if these glues are available under any other brand names. I can source them in Australia, but its been my experience in the past, that products like this are often available under other names and are occasionally much cheaper.
I noticed a lot of the diving forums use “shoe-goo” available at Woolworths for fixing…[Read more]

Bruce replied to the topic Inflation bag – update in the forum DIY Packrafts 8 years, 5 months ago
I installed a schnozzel in the inflation bag that came with my latest V# kit. The idea was suggested by Lyn. It originates from Exped Schnozzel Pump, makers of sleeping air mattresses.
I find the corner installation to be fast and simple. I used 210D fabric for the schnozzel so it wouldn’t twist and shut off during inflation.
To dashion the…[Read more]

Hi Lyn, thanks for posting this report and especially the video – it’s very helpful seeing your technique in action!
