Could I kindly request that this link be made a sticky please? Tony asked a while back if he could make it available for download via BCUK with the other pdf's but I don't know whats happened to the main site and if/when it would be available for folk.
Thanks in advance.
Updated links for white background version available here (http://www.louisecainphotography.co.u k/bushblade/downloads.html)

Very very helpful!!!!! Should 100% be a sticky:)
Made it a sticky, though a pitty the info isn't in the thread - though until the front end is sorted and we can put it up in a tutorial section, I think it'll fit here nicely.

FYI, this maybe of interest to fellow Hammock-ers. :hammock:
Can't remember where I found it but it explains the different forces involved on the rope/tapes and the trees, depending on the load (how fat you are) and the strength of the ropes/tapes you use to attach to the trees. In relation to the angle you like to hang your hammock.
The most interesting section is 'the tensile force on ropes'
It looks like if you want to get close to the rated value of your tapes/ropes you need to have an angle of 30 deg... :confused: That don't sound to comfy for sleeping.
But non of this makes any allowance that when you tie knots in your tapes/ropes this drastically reduces the tensile strength, quite often by a factor of 60%.

So bottom line, make sure you don't use 550 paracord tied together and try to sleep as flat as possible unless you weight about 4.5 stone. Cos' your ass will end up on the floor... :stretcher:
(I know people will have lots of stories about putting a family size car in a hammock with only a bit of paracord... but I'm only sharing the maths so don't shoot the messenger :D)

Good work.
Any chance this could be changed to black text on white background for easier printing??

Those numbers seem to be wrong (Yes, I'm the sort of person who checks them).

LMAO...
I be disappointed if we didn't have someone here that would check.
Don't forget I did say that I had just come across this and was just sharing the find.
So is all a load of pony???
Is the theory sound?
Do enlighten us.

Sorry FreddyFish i meant the original hammock and tarp guide

The theory is sound, the formulas are correct. It's just that the numbers in the table are not as accurate as the two decimals suggest.
Example with two decimals accuracy:
For a weight of 250 lbs and an angle of 5 degrees, the tensile force should be 1434.21 lbs and not 1434.48 lbs, a shocking difference of 0.27 lbs!
Edit: also, the 200 lbs 5 degrees example (above the S vector) is wrong - about 100 lbs off.

We do plan on making a white background version as quite a few people have asked for it. I'll make it available for free download from my site when its done, so please check back. It may be a while though as its just me and my girlfriend and we've got quite a lot on lately.

Excellent thanks
What format was it originally in?

It was an executeable file done in photoshop, like a slideshow. I have jpegs of all the images too. You're certainly welcome to try, I'd hapily send you the images on cd if you pm or email me your address.

On saturday night 'in the field' I managed to remember the two main knots from a couple of reads through and one practice in the garden at home.
So i could probably get away without printing it now, but if you've sent it i will take a look and see what i can do still

Thanks for the tutorial, it will help a lot when I go away next month.
I am also removing the plastic adjusters fom my tent as I no longer need them thanks to your advice.
Should save myself a few grams?

Hi, glad it worked for you. No I haven't sent it yet, do you still want it?

I've just made this available for free download from my site too. There's been quite a few requests to make a printer friendly version with a white background, we do plan on doing this soon and will make it available for download when its completed.

I'm not desperate. If you think it might be a while before you convert it i'll give it a go for the benefit of others.

I`m interested in this as i have just made a prototype strap that can be adjusted from both ends for length but also has a lot of other tension questions that i could do with some help on if there is a willing member who could be trusted not to run off with my idea, lol. ( no smilies on my comp` showing, sorry)
Hi All!
I have a DD Travel hammock. I`m thinking to get an under blanket as well. How is that works? Can I sleep with this at winter only use my summer sleeping bag? Thanks

Which under blanket are you thinking about getting ? If you go for the Snugpak one you'll be toasty underneath but you might feel a chill on top with just a summer bag. I use a full length down UB from the states along with a -10 Aplkit down bag for winter hammocking.
Have a look at hammockforums.net if you've not seen it before, there's some great vids on there
With an underblanket, the sleeping bag doesnt need to be used underneath you and can be just used as a quilt with a footbox-this gives more loft and warmth to it in a hammock. Using them like this will leave you with a cold head end though.
I have slept in the snow at -5 with no bag and 3 foam mats and was properly warm, but then I am a bag of lard and by all accounts, a bit strange. :)
It all depends on the user, but if your an average warmth/cold sleeper, you will need something warmer.
I`ll checkthe hammockforum than. Thanx!

Hi guys, due to many requests to do so, we have now made a more printer friendly version with a white background.
I'll update my OP with the links also but here it is

Thanks again for all the kind comments and I'm glad people are finding it useful.

where do you buy your tapes from and how much are they?
where do you buy your tapes from and how much are they?
I've always recommended Walkhigh but they seem to be having a few issues (http://www.bushcraftuk.com/forum/showthread.php?t=61902&highlight=walkhigh) at the moment
I think I had the same stuff as Will which is the 18mm tubular stuff here (http://walkhigh.co.uk/acatalog/Cord_and_Tape.html)
Any polyester climbing tape will do you as long as it's rated
DD sell some hammock tape (http://www.ddhammocks.com/products/cordage/strong-webbing) but I'm not sure how good it is, I know the old stuff used to stretch something rotten but I think Nicks got better stuff nowadays.
excellent guide, but me being me I'm having a little problem with the first knot. when I put tension on the line the knot flips over the line and seems to partially undo. it still holds very well,but I'm not certain I'm tying it correctly. does this knot have a name? if so I could look it up and try with different instructions etc
Many thanks roy

Is that the tarp ridgeline ? Which page of the tutorial is the knot on which you're talking about ?

Not sure of which page No, but the first knot on tarp line.

Do you mean the evenk hitch like this, about 30 secs in ....

Yes, yes I do.
It would appear that I was tensioning the knot incorrectly and it looks a bit more obvious in the video.
Many thanks for your help :)
Yep after having another go once I got home from work, I can confirm it works just fine thanks for the help again and for a great post
