Mark started the topic Finished my V3! in the forum DIY Packrafts 8 years, 6 months ago
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]

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’m still squirrelling my…[Read more]

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, 6 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]

Stevoggo replied to the topic Seamgrip vs Aquaseal in the forum DIY Packrafts 8 years, 6 months ago
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, 6 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!

I tried using a larger pistol-style hot air gun, myself, and quickly gave up on it…[Read more]

Hi Lewis, thanks for your interest in the packrafts!
I’m not aware of anyone making a traditional multi-chamber inflatable from one of my designs yet, but it shouldn’t be too difficult. It’s a bit more work to seal off different sections of the tubes, but it can be done. If you cut the side tube in half and add an extra-wide seam there, you’ll…[Read more]

Hi there,
Looking forward to ordering my V3 kit in the next day or 2. I was wondering if there was a way to make the raft into a multi-chamber (2) raft. Has anyone done that? Is it possible?
Thanks

Veets replied to the topic Other Inflatable Projects in the forum DIY Packrafts 8 years, 6 months ago
Thanks for the feedback.
I did some more reading, and it seems like maybe the thing for this idea is the “drop stitch” internal structure, for high pressure and rigidity. I don’t see anywhere that the internals can be bought online, for a DIY project, so perhaps it will just have to remain a future plan for now.
