Self stretching bug net II
- Second chapter on the self stretching bug net...
I also did some thinking about why my bug net stretches from one end
of the hammock to the other without a ridge line... I discovered a
neat little piece of geometry which may help some you as hammock
For this thought experiment, your home-made hammock long edge is 10
feet long during construction. You build a bug net which you hope
will cover the kayak shaped top opening of the hammock so that there
is a curved edge. The long curve is bowed out 14-18 inches at its
center, and the curve is 10 feet long. You sew the two ten foot
lengths together on one edge of the hammock. Now you knot the ends
of the hammock material and leave most of the bug net free.
When you stretch out the hammock, the bug net will keep you from
stretching the hammock out along its 10 foot (shortened by the knots)
edges... They will be hung in a proper hammock shape, but the top
ridge of the bug net will be nice and tight, from one end of the
hammock to the other... Voila! an improved bug net system. Then
either use velcro to close the open side or a weighted stuff sack to
hold it closed. This decreases the weight of the hammock by the
weight of ~19 feet of velcro and gets rid of those nasty sharp edges
of the velcro strip which seem ready to cut the hammock material or
It also makes the hammock cheaper by 20 feet of velcro.
