Anyone made their own gear from Dyneema?
« on: July 28, 2020, 10:02:38 pm »
I'm tempted - looks like fun. Sewing not needed - glue and tape do the job. Apparently the hard part is cutting it. You need a hot wire gadget  or serrated shears.

There's a chap sells pouches and other bits and bobs made of dyneema on eBay but I think they are sewn.
Where did you find the glue and tape information?

Reading around on the mfr's site and those of the 4 official suppliers of DCF: https://www.dsm.com/dyneema/en_GB/where-to-buy.html

I'm not that excited by 3 grams saved on stuff sacs. And stuff sacs tend to get abraded, so they're not suitable for the lightest grade of Dyneema, 0.34 ounce per sq yard. That stuff is better suited to tarps and tent bodies. If i used the .34 to copy my silnylon tent, which is 800g excluding poles, the weight would come down to 130g. 
An  expensive project. $32 per sq yd for the Dyneema, so about $350 all in I reckon. But a 670g reduction is attractive.

Also thinking about lightening my Thermarest cot base and getting it to double as a chair. And swapping the ally struts for carbon.

And perhaps making some stupidly light street clothes. Not necessarily out of Dyneema. Maybe polyester membrane https://ripstopbytheroll.com/collections/ultralight-nylon-fabric/products/0-9-oz-membrane-15-ripstop-polyester-hexcam?variant=12408510939184  or taffeta https://ripstopbytheroll.com/collections/ultralight-polyester-fabric/products/0-9-oz-membrane-15-poly-taffeta?variant=21575967553

Good ideas.

When my new bivi bag arrives I may be making a tarp. When I traded my Thermarest self inflator for the small Neoair I modified my seat cover with a bit of nylon that I had. I hadn't thought of altering the poles and I can see if I did it it with Dyneema and carbon there would a weight saving. Thanks.

The cot is so comfy there's no need for a mat. No more inflating and deflating and wrestling it into the stuff sac. If I can savagely reduce the weight of the cot and get it to double as a chair I'll be mucho contento. I'm going to experiment with carbon tubes and/or rods from here https://www.easycomposites.co.uk/#!/cured-carbon-fibre-products

Thanks for the links. The carbon tube is reasonable prices.

I'm going to try rod instead of tube for the tent poles. They are 8mm Fibraplex, about 25g per metre, so I can't complain about them. They've lasted brilliantly. But what if I tried 3mm rod instead? It's about a quarter of the weight, and bendy enough. I don't see why it should snap, it doesn't really do very much. Might as well try. I think the best thing about making your own stuff is you can risk very fragile constructions which the manufacturers daren't try.
