Hmmmmm. When I raised this question I thought that with a bit of luck I might get a response or two that could save me a bit of reinventing the wheel. Instead I got a complete set of blueprints for a mission to Mars. Thanks, guys.
About the only suggestion I can make comes from my experience in the woodworking shop. If you use toggles or marlinspike hitches, don't give up on wood if you have access (such as a woodworking friend) to small scraps of exotic woods. Two in particular would be well suited by reason of surface hardness and extreme strength. They are bloodwood and ipe. Bloodwood is sometimes used for bows for stringed instruments. Ipe is the most common name for a wood sold under several names (all are Tabebuia seratifolia) and commonly used for docks, wharves, and flooring for boxcars. Lacking a lathe, chuck small sticks in a drill press and shape with a wood rasp and abrasives. Leaving a small ridge on the ends should address the concern raised by FishinFinn of having a toggle drop out when not under tension. To keep a small toggle or 'spike from getting lost, leave a long tail when tying the loop on the end of the line. Drill a suitable hole in the end of the toggle and glue the long tail into the hole with a dab of super glue.
I did also (just for the heck of it) try the same thing w/ a hollow, aluminum, afghan needle (knitting needle?) from wal-mart. It bent, but the hollow Easton brand stake showed no signs of trouble. I used it for quite a few nights sleeping, mostly at home & a few on trail.
don`t leave the CREATOR out of the creation!
For some time I have used a stake-pin to join the webbing from the tree to the line from the hammock. I use two 5-inch lengths cut from a Swifter dust mop with an aluminum handle. The tubing is about Ĺ inch in diameter and the two rods together weigh little over an ounce. The webbing is doubled and inserted through a bowline loop from the hammock line and tensioned as much as wanted. Then it is brought over and secured with the rod in a marlin-spike type hitch. As a mental security blanket I also tie a slip knot although Iíve never had it slip. It acts as an effective drip line as well. What I like is when youíre ready to break camp you only need to pull the pin out and the whole ensemble comes apart. Also it doesnít crumple up your webbing from knots. Iíve used it many times and the rods havenít bent at all. Theyíre as straight as when they were first cut. The slickness of the aluminum helps on a smooth extraction when youíre ready to break camp. Would welcome other comments.
