Pole support for hammock on open ground.

Simon I am embarrassed to say you were the first thing I thought of as I woke this morning..
Lets all put our heads together and sort it out for yer.
First I/we will need the length of the two poles yer want to use ( each max )
2 what height above floor do yer want yer bum
3 what is the length between the rings which gather your strings from end of yer hammock ( laid flat )
4 Do you have quite a lot of string/rope strong enough to carry your weight
5 how many pegs do yer want into the ground ( I would think at least 4)
6 lastly have you an expected height difference between lowest part ( yer bum ) and the head of the hammock
7 would yer prefer inches or silly metric and if metris cm or mm please
Thattle do for starters

I will provide drawing for yer (so may others I suspect)

So what angle do the poles need to be at in order to get them only in compression? This is the bit I am struggling with that all other uses have no problem with.

Vertical.

The compression (upward) force has to oppose gravity (the downward force).

The sideways forces will be balanced by your guy lines. If then are not, it will all fall over.

WELL, I didn't know you cared! :hug
I will try and keep in order of question:
Poles, ideally 5'6" to hanging/guying point... the poles might be a little longer to allow the tarp to be above the hammock - no stress supplied by the tarp as it only weighs a couple of ounces.
Bum height anything from 12" to 24" - whatever it needs to be to reduce the loadiging. I can wrap myself into different shapes!
t'hammock between poles (including the bit of string from the end of it to actually attached to the pole) 11' 6"
Plenty of guy line - not so much on the hammock hanging points, but I can always bend some extra on. Guy lines - 50m arrivng today of 450kg BS.
Pegs into ground - the system works with 4, being 2 at each end splayed out at 60 - 90 degrees. BUT, I can work with 6.
Head to bum height difference. The optimum angle of hang for a hammock is 30 degrees, apparently.

Hope that gets yur juices flowing.

I have another ride out planned after a breakfast. Hopefully one that will keep you engaged for the whole trip. :beerjug:

It has been interesting to ‘watch’ Simon’s experiments. At least he is having a go (y)

It got me wondering as to when the first man conceived of a hammock, and when a man first dreamed up the notion of suspending the hammock when there are no trees? The maths of the physics behind it are quite complicated, I guess. I wonder who, in the distant past, quantified them? Newton? Archimedes?

The shape of a hanging rope is called a catenary - it's a line through which the forces of gravity act.

The same shape when inverted forms the basis for a free-standing arch (like the St Louis Gateway Arch) and, thus, domes (such as St Paul's) and vaulted ceilings (such as King's College Chapel, Cambridge).

NB it isn't the same as a parabola.
 
How are you attaching the hammock and guys part way down the pole?

On my next attempt I will have stacking tubes.... they are telescopic tube blanks, standard 89 Aluminium (6062?) 2mm wall thickness, OD diameter goes up in 5mm stages from 10mm through to 80mm - all at 2mm wall thickness. I can get them in 500mm or 600mm lengths. I was going to go with 600mm x3 sections to give me the 6ft length (ish). The American commercial system is 5 sections of telescopic extrusions, they have a kidney shaped indentation at the back, as in an inward curved 'side' and are 5ft 6in long when extended. I could use more sections to make the packed size shorter. I was going to drill through the top end of each section about 50mm down to put a bolt through, just as a shelf for the next stage to sit on. and one at the top section to act as a peg for the lines to stop them sliding down - although there are jamming hitches that will also hold fast on a tube (the Rolling hitch, also known as a Midshipman's hitch).
 
All this faffing around... all very well in dry, sunny climes BUT you'll wish you had a tent when:
  1. It is windy
  2. It is cold
  3. It is raining
  4. Or there is fog
  5. When you need privacy
  6. When you need your kit in with you
  7. When you are tired or sick
  8. You don't have room for an insulating mat below you
  9. and so many other reasons.
Yes I carry a tarp - 4x4meters in the car and a 3x3M ultralight one on the bike plus an ultralight hammock for both- I have never not found somewhere with trees or attachment points. Having the right length of cordage is key, knowing knots helps.
Still I respect your choice but do remember this old gits' words when you're trying to set your camp up with your poles in adverse weather conditions...
Buena suerte

Some of the Scottish islands I plan on boating to have no trees, not even small thorns, not on the beach anyway.... the hammock takes up less than half the space of the tent and is half the weight. It is also MUCH more comfortable to sleep in than a tent with any kind of camping bed and mattress that I have found. I have an Exped Neotherm and a Helinox cot and an Army version with canvas bed on steel supports - the hammock trumps them all, especially in the winter. I have hammocked in that very cold spell we had about 12 or 15 years ago and was toasty warm, although I was younger, my sleeping bag was not as good as my current one, even with the fleece liner. I will still use a tent, but the hammock is a wonderful option on the bike and the boat.
 
I cannot believe I am the only person amongst the many following this, to have a sudden overwhelming urge to get out into the garden and have a go!

Tell you what, when you crack this, there will be a huge run on people buying tent poles, 'tis the GSer way.

I'm going to corner the market now.

As long as you all film your hammock mounting techniques and share them here
 
I have had a chap from Netflix in touch with me this morning Simon. More later...

To start with I recon the top of the hammock fixing rings needs keeping apart with another set of tubes, this would also act as a horizontal support for the cover sheet above yer head. whatever angle that is created with the ropes from hammock rings to top of support poles then down to floor needs to be equally spilt so to put same pressure both sides of the tubes.
That's it
Jobs a gud un
Over to the next expert
here's my drawing for reference
Next job please .......

You've made the hammock into a complex pendulum!

If you want a cross-pole, why not attach it to the top of the uprights?
 
So have we got this erection up yet or not?
Have you become a pole sitter by accident?
 
Yes that's right
Its a "complex pendulum 4 strung Hammock suspension set up"
The "erection without a crosspole"
