Hello all! If you are like me, you find enjoyment out of making your own items, otherwise you probably wouldn't be on this website!

After recently purchasing a couple of hammocks, I went back to look at purchasing some straps to assist with fastening to a tree. Was shocked that the strapping materials in a kit cost way more than the 2 hammocks I bought put together. So, I set in to make my own!

1st you need to find your local outdoors store that sells climbing ropes and strapping material. As you see in my materials list, I purchased some hollow strapping 1" width. It will be your judgement on the length you wish to purchase, but as I bought, 2ft is sufficient for each end, and enough to go around the back side of each tree to protect its bark and/or trunk from damage.

Materials:
Hollow strapping material (2ft per end = 4ft Total)
Paracord (however much you need) I am using approximately 11-12ft as explained further in instructions.
Lighter
Scissors
Carabiner x 2 (durable to withstand weight limit; NOT the cheap $ store kind)
* Hammock
* Lastly, two trees


Next step!
1. Cut your strapping as mentioned above, into approx. 2ft pieces. If you pinch strap together you can see how this material is hollow. Once separated, lightly singe with lighter to prevent further fraying.
2. Paracord: First double the cord in half to aid in strengthening. After doubling, cut to desired length. I used a piece about 11 to 12ft in length.
3. Once doubled, slide paracord thru strap until you can grab on other end of strap. This can be a little tricky to slide thru, but if you maintain pinching strap in half it will help.
4. Now that you have the strap slid thru, take the loose end and tie together in a quick knot.
5. Next step will be to go down end of cord and tie several knots, which will help when securing hammock to strap. Depending on the distance between your two trees, you can adjust tension by moving to the next knotted area as seen in photo with carbiner.

That seems to be about it. Will try to show photos of strap in use, but currently hammock is hanging around down in basement until further use!

Also made a carry bag to keep straps in for carrying in your backpack, which I can show in separate Instructable.
 
Good Instructable. I look forward to the pics. Just to let you know, you might want to double the amount of paracord you are using. The math works out as a rule of thumb to divide minimum breaking strength by 10 to obtain safe working load. Also knots will diminish the minimum breaking strength by around 15%-20%. So for a 200 pound man you would need 4 strands of 550 paracord. (550+550+550+(550 * .80))/10=2090/10=209lb safe working load. This is only to account for sudden load shock. Such as if a big boy jumped into the hammock, it can briefly overload the paracord and cause it to break. It took me a lot of digging on the net to find the math. It was on a firemans training manuel (PDF) for emergency rescue of people trapped on cliffs and what nots. I used this math on my 8 strand emergency rope I made out of paracord plus de-rated it by an extra 25% for my personal peace of mind. Keep up the good work. Way to make my friend!

I know this is an old post but here's a formula to determine the number of strands you will need for any particular weight. #strands= (weight+11)/55 round your result up to the nearest whole number.

so, I need 5 strands to hold my weight (230 + 11)...I use 250 to keep it simple...but you are saying 50' of 5 strands will hold the same as 10' of the same?
What I am getting at, is, do we not take into account the length?

I guess the length and number of strands depends upon the person. I am only 175, and I have two strands going around the tree. Doesn't sag in the least bit.

yeah, sorry about basically "thread-jacking" this...I was referring to Loki_Thor and his 8 strand emergency rope...I should have been more specific. I am going to make my hammock straps out of a single piece of paracord, doubled and strung through the hollow webbing (one for the head and one for the foot of the hammock).

Firstly, Sorry for the loooong post

@Firehiker-the formula I got is an absolute never break under any humanly possible conditions designed for life or death situations. And your set up to double and string through the tubing is awesome and generally works with the formula because you will end up with four total strands of paracord(two strands at each end) to support the weight which factors to 209 lbs of safe working load. Working load is only a calculated number based on max breaking strength ( i.e. the 550lb rating on Milspec Paracord) So over rating the material would still give a massive safety margin for your setup by almost 1500lbs! The formula is compensating for Shock loads when you involve mass in motion which creates kinetic energy. Such as how a tiny bullet that only weighs 55 grains can hit with 400 lbs of force. You would have to drop into that hammock from 10 feet up to break the cords.(although, I wouldn't try it)

550lb paracord would be commercially marketed as 55lb working load cord in a store. It all just depends on the advertising. This formula is most definitely overkill for basic camping needs and hammock setups. But my emergency rope I have used for rappelling which falls into my life or death situation so I am very very pessimistic about calculations when I'm 30 feet from the ground. I would make a loud thud if I fell :-)

Again your setup is way awesome and well above the needs of any hammock setup.

Thank you for the advice. I wasn't thinking about doubling any breaking point due to our hammocks themselves are not rated for higher load. But hopefully all will read your subsequent post to understand strengthening the rope.
