New D4 Delta2p Portaledge
2019 Announcement: New D4 Delta2p ledge
Just want to let you know the past year I have been working on a radical new portaledge design for two people, where both people can have their head to the wall. There are a lot of advantages in comfort in this design, one of the best is that you always have a solid backrest (the wall) to lean if you want to sit up in your sleeping position. It's also really easy for each person to exit the ledge without a lot of weight shift or crawling over a partner.This new style of portaledge has been a dream of mine for many years, around 20 years ago I made a folding prototype, but it still needed work in the way the frame and suspension work together.
I am happy to announce that my new design, which I call the Delta2p (Delta shape, 2 person--I also plan a 3p version) has exceeded all expectation in terms of ease of setup and stability, thanks to many new portaledge design aspects I have learned with my other D4 design innovations during the past 3 years. It is also light and strong, with a six-piece curved-corner, hybrid diameterf rame wth the D4 patent pending bullet joiners, which packs to 36" and is taco-proof by design.
I am looking for product testers--folks who will use the ledge in the coming months, spend time playing around with it even if not on a wall, and can send photos and feedback.I plan to build a small batch of 8-10 "pre-production" Delta2p's for such folk to get more feedback for the final production version.
Size is 79" x 56"/33", and weight is less than 8kilos--very similar in usable space and weight as the D4 Alpine Double ledge. Note that this design does not have the A5 divider fins--the delta shape allows the bed to be tightly tensioned, and although there will be some "friendliness" with two people, it is suitable for people who are happy with simplicity (less straps and tangles).
If you have been following D4, you will note that I live in Australia, and usually around this time, the end of the year, is when I start offering new designs. This is for two reasons--1. it's summertime here! and the shop is warm (winters are too cold to make stuff), and 2. I work as a teacher during the Australian school year (Feb-Dec), so have less time during the main northern hemisphere bigwall seasons.
If you would like to see some of the Delta2p development, check out my instagram (bigwalldeuce) and facebook (bigwallgear).Also please follow my twitter (also bigwalldeuce) as I often seem to delete my Facebook and Instagram accounts, especially around election time, but plan to keep using twitter to keep up with events of the world. I also plan to continue publishing open source info at the BigWallsForum.
You can see this new ledge's stability in Steve Pearce's video. (note this was thefirst 80% scale version, the current version is much bigger): https://www.youtube.com/watch?v=apR678UpA8E You can also see the instantframe setup here (with fabric, there is always a bit more guiding of the assembly):https://youtu.be/sS31FEQ8TiE
