Cuben Sawyer Squeeze Bag on 03/20/2012 08:13:17 MDT Print View

I put this together this morning and have not tested it yet but I think it is going to work great. I used a piece of scrap cuben so the lines are from a older project.

It does not register on my postal scale!

I used the top from a sawyer bag and glued it in with Hysol U-09LV.

I put a piece of printing paper next to it for scale. It will be bit over 2 liters.

I glued two strips of plastic on the outsides of the top edge for support when filling and to help when rolling the top for squeezing.

Looks nice. Are there any health side effects from ingesting possible fibers from the material?

No, that would not be a problem. The filter is rated at 0.1 microns so if it were they would be filtered out.

If the glue around the top holds well, they are so light I can carry a back up.

They will also easily tape up with tenacious tape if damaged.

Well ... working on it.

I am trying out a different adhesive and better way to seal the bottom to take much more pressure.

I have tried a few adhesives but they are not strong enough for the pressure when squeezing.

So ... I have a new cuban bag for my filter set up ... or a stake bag ... one cuben gaiter ... one rain mitt.

A thought about reinforcing... on 03/22/2012 16:37:42 MDT Print View

Would it be worth sewing a reinforcing material around the edges of the bag? Such as grosgrain or something similar? With the reinforcing material sewn to itself through the edge of the bag, then seam sealed with adhesive on the inside of the cuben, would it offer enough reinforcement against pressure for this?

It would add a (small) amount of cost and weight, but if it works...

Anyway, just a random thought.

Craig, is this working out for you or have you abandoned this idea?

gravity filter? on 04/10/2013 19:16:37 MDT Print View

I see that your setup didn't handle the pressures of using it with a squeeze filter, that's unfortunate. How long do you think it would hold water simply hanging? I see this as a great starting point for a gravity system. you've already reinforced the top, you could simply punch a couple of holes through the cuben/plastic and add some cordage to hang it.

Maybe someone has done this before, but I bet with a cuben dirty water bag, you could shave a decent amount of weight off of most gravity filter setups.

Does it work if you roll the bag rather than squeeze?

John abela on hikelighter noted that by rolling he was able to avoid failure of the stock sawyer bags that failed when people squeezed too agressively

Wow - this is still getting interest.

I have an idea that I have not tried yet but would definitely work for a hanging bag and would most likely work for a squeeze bag.

I am getting ready for a three day trip in the Smokies and I will make it when I get back and post the results.
