Cuben Material Project Number 3: (This project was finished on Sept 23, 2005)

Part 1:
Cuben Water Bag Replacement for an - Amigo H2O Water Filter System:

I had a small piece of the Cuben fabric left over from my Pack Bag and decided to replace the Bag from my ULA H2O Amigo water filter with it. The ULA bag with the fittings removed weighed 1.96oz. The Cuben replacement bag weighed 0.57oz or a savings of 1.39oz. I will replace the ULA stuff sack with one made from the Cuben fabric as I have more scrap.

I will multi-use the tubing from the Amigo on my Platypus bottle and save another 0.23oz.








I wanted to use a piece of my "Yellow" AirCore Pro Ultralight Dyneema" shelter guyline from BMW for the water bag cord.

The yellow stuff is 3/4" grosgrain folded in half and pressed with a hot iron. I used the yellow so my colors would be the same. I then sewed around the outer edge of the Cuben material with the yellow grosgrain for reinforcement. Then I punched 16 holes in the grosgrain and strung the "yellow" AirCore Pro cord through the holes. I made the two Plastice Tube handles from two 4" pieces of the tubing from one of my feeding tube food bag sets and was done. Most any light weight plastic tubing could be used. As I said above the weight of the water bag went from 1.96oz to 0.57oz. A nice weight savings.

Part 2:
Filter Replacement:

There was a disscussion on the yahoo group - Backpacking Light about replacing the Amigo inline filter with a Katadyn Hiker Pro filter and put it inside the Amigo water bag. The Katadyn Hiker-Pro filter was said to filter water faster than the filter that comes with the Amigo. I had looked at the Hiker Pro filter but hadn't bought one to see if/how it could be used with the Amigo H2O Filter set-up.

I bought a Hiker Pro filter and it was really easy to covert the Katadyn Hiker Pro filter to my Amigo system. When the water bag has water in it and is held up or hung the filter seems to float upright and filters fine.

If you have an Amigo a look at the pictures should be enough to figure out what I did. If not ask.







Part 3:
Completely New - Home Made Water Filter:

Cuben Water Bag/Gravity Feed Water Filter- 5.61oz

Back to the Hiker Pro for a moment. I just weighed my filter. I had to wait till it dried out. It weighs 3.62oz on my gram scale.

But as I was looking at the filter I had to ask myself why do I needed all the extra plastic around the screw part (Out-end). Why not cut off the extra plastic. I also removed the O-ring.
