<h1>Bivi Riggin Guide</h1>
|
|
|
|
<p>Every year some poor bugger who has probably never done it before it
|
|
gets to rig the tarps and be responsible for any soggy miserable
|
|
nights that might result if it's not done well enough. Starting from
|
|
the bare space it's really quite hard to know where to start if you've
|
|
not done it before, so this doc attempts to provide some advice.</p>
|
|
|
|
<p>Note that this was written after Wookey+Joe's rigging effort in
|
|
2014. It is not necessarily optimum, but did seem to more-or-less
|
|
work. Feel free to imporve it over time.</p>
|
|
|
|
<p>There are two essentially-separate jobs:
|
|
<ol>
|
|
<li>set up the
|
|
water-collecting tarp</li>, and
|
|
<li>set up the main tarps</li>
|
|
</ol></p>
|
|
|
|
<p>If there is any chance of it raining soon, start with the water
|
|
tarp, as you <strong>really</strong> don't want to miss it, and
|
|
setting up in the rain is rubbish.</p>
|
|
|
|
<h2>Terminology</h2>
|
|
|
|
<p>I will describe things as if standing at the bottom entrance looking
|
|
up, because that works for all three sections. So the
|
|
<strong>left</strong> wall is the
|
|
gear/stove/animal-hole wall. The 'back' is the top end of the bridge.
|
|
The 'front' is the main entrance.</p>
|
|
|
|
<h2>Water tarp</h2>
|
|
|
|
<h2>Main roof tarp</h2>
|
|
|
|
<p>This is one large tarp covering more than half of the internal
|
|
roof. There are two main cross-ropes to hold it up, ties at the back
|
|
edge and 'knitting' to reduce sagging in the almost-flat central area.
|
|
The objective is to get it taut enough and square enough that almost
|
|
all the water runs down the top and out the front not collecting in
|
|
'buckets', which then drip. That means that it has to be fitted quite
|
|
'flat'. </p>
|
|
|
|
<p>Start with the big green 10x10m tarp. It seems to be near-enough
|
|
square so don't worry which way round you start. The basic position is
|
|
that it goes all the way to the right wall, partly 'underneath', and
|
|
the left hand edge is about in line with the steps up the middle. The back
|
|
edge lines up with where the roof rises at the back entrance.</p>
|
|
|
|
<p>Start by rigging
|
|
|
|
<p>So start by opening it out to full width on the wide central
|
|
bed-shelf. and pulling the RH edge </p>
|
