This is a group buy for lightweight 20mm (18g/m) and/or 25mm (24g/m) olive green polyester webbing for hammock (or other) use:
Available from this Finnish supplier: http://www.shelby.fi/catalog/product...oducts_id=1127
This is the lightest polyester webbing I've come across; most polyester webbing is tubular and therefore weighs twice as much. Note that polyester doesn't absorb water (and stretch) like nylon and is more durable than polypropylene. A useful comparison of PE vs. PP is here: http://www.haywoodproducts.com/webbingstrapping.
Static hammock tape tensions in kN are given by the formula (W * 9.8 / 1000) / (2 sin α) where W is your weight in kg and α is the angle of the tape drop from horizontal. For a 100kg load, the static tape tensions are approximately:
When tapes are 10° from horizontal = 2.9kN
When tapes are 20° from horizontal = 1.5kN
When tapes are 30° from horizontal = 1.0kN
The 25mm tape has a breaking strain of 5.2kN. The 20mm tape should have a breaking strain of about 80% of this (4kN). Either tape should have a good margin of safety in normal hammock hanging scenarios and use (i.e. you don't bounce on the hammock or string it close to the horizontal).
Group buy details:
This group buy is at cost. €0.85/meter (20mm) and €0.95/meter (25mm). The supplier gives a 25% discount on a complete 50m roll. Shipping costs from Finland are a fixed €16.90 (http://www.shelby.fi/catalog/shipping.php) and are obviously smaller on a per metre basis the more that is ordered.
I want 10m of the 20mm tape so, ideally, I'm looking for takers for the remaining 40m of a 50m roll. Obviously I can order more than 50m and per metre shipping costs will be even lower. I can also order 25mm webbing, but would prefer that the purchase of a whole 50m roll of 20mm is covered.
Black is also a possibility, but only if there are enough olive green takers.
Orders in 1m multiples please.
Jiffy bags at cost.
UK delivery will be Royal Mail 1st Class:
