    just cut my large neoair and resealed it. couldn't have been easier.

    now for step 2…

    where do i get a valve to make the short piece a custom neoair seat/inflatable pack frame?

    anyone know where i can get one or two? anyone have any advice? i know people have done it, but can't find any threads spelling it out and i'm a very novice myog'er (although prolific gearswaper :-)

    thanks in advance.

    Thermarest sells a Valve Repair kit. "It includes HotBond™ adhesive and a high-flow replacement valve that installs in a snap." REI sometimes carries it, but most likely you'll have to buy one from their website.

    If you do, also order their Fast & Light Repair kit for punctures at the same time. You're already paying for shipping. "Trail-ready kit makes speedy repairs easier than ever before. Self-adhesive patches make for quick and neat work without messy glues or long cure times. For use on all Therm-a-Rest mattresses except for Luxury Map™, Luxury Camper and LE mattresses.

    Kit includes: (3) Alcohol Prep Pads, (6) Glue Dots™, and (3) Cover Patches"

    Not readily available in small quantities sadly (I've done a ton of searching with not results yet). Still you may be able to to craft your own out of some kind of plastic, like a blank nylon block. Worth looking into at least.

    "this is just the male adapter. anyone know where i can get a full replacement valve?"

    There is a female component? I don't have a thermarest pad to look at, by my understanding was that the male component was just bonded ("potted") into the seam. I've used these replacement valves to make MYOG inflatable sleeping pads, and I just bonded them into the seam. Bender (of now-defunct Kookabay) made all of his early pads this way, I think.

    I'm actually stuck at the valve-selection stage of a MYOG inflatable sleeping pad project right now. More recently I've used Airtime kite bladder valves instead of Thermarest replacement valves because the kite valves are soft (less strain on surrounding fabric) and seem more durable. But the kite valves are bulky. I haven't found a commercially available alternative that is any better, though. So I'm making plans to fabricate my own valve. It will be time consuming, but I don't know any other way.

    I once found an old inflatable sleeping pad from the 1980s at a garage sale that had two valves that were just like Exped's valves: flat and rubbery. They were perfect. I bought the pad for $1, cut the valves out, and used them for an MYOG pad that I later gave to a friend. I wish I could find more like those.

    I have a bunch of valves like these (the ones I have are not Halkey Roberts but they look the same)that I would be willing to sell. They are PU valves so they work with TPU coated heat sealable fabric.

    http://www.halkeyroberts.com/products/inflation/inflation-closures/closure-and-flow-check-valve.aspx

    The problem for most folks with either the seam mounted or even flat mounted sleeping pad valves is that they require dies to ensure a solid secure seal to the fabric. I used the flat mounted style on the inflatable floor for a boat project we have been working on.

    Marc, I would be interested in buying 4-5 of your TPU valves. I'll send you a PM.

    Also, the panel/seam design of that boat in the facebook photo in the link you posted is clever. I've never seen one like that.

    Whoa…I just noticed the caption in that photo. The boat weighs 11 ounces? I don't want to drive this thread off topic, but I would love to know how the boat achieves that weight (ie, is it a balloon-in-envelope design?).

    My suggestion is to post a new thread in the gear forum just updating the BPL community about your recent projects and prototypes. I'm impressed with the innovative ideas that seem to be stirring in your shop. An update thread would be a good way to get people interested in Flyweight Designs.

    Thanks for the comments Colin. It is a new project that we are finalizing.

    I also have to apologize. The red valves that I have are actually PVC, however, I was able to mount them to heat sealable TPU fabric as they are incorporated into our AirLyte drybags. I apologize for the confusion, I was mixing them up with the mattress valves we have.

    For anyone that wants them I could probably sell the red valves for $1 a piece plus $2.50 in shipping. The shipping would probably be static for up to 10, but I would have to double check the weight before I fully commit to that.

    Colin,

    The inflatable floor weighs approximately 11 oz. The boat w/o the inflatable floor weighs 3.5lbs.

    Hey, I saw this older thread and was wondering if anybody has had any luck with using the short end of a cut neoair xlite? I have one I want to cut down and thought I might use the short end for my dog if I could install a valve. I actually have a valve from another trashed neoair which I bought on craigslist that wont hold air. I could cut the valve out but I'm not sure how to seal it into the newer xlite short end. Thanks for any ideas / suggestions!
