Testing a tube on a drizzly, grey overcast, September
afternoon.
(This is England! And isn't it typical.. This is the coldest day
(15/9/99) since I starting that temperature logging project in May, and,
yes, I do know, winter's on its way, and it will get colder, but it's still
bloody typical.)
|
 |
Seems to work! |
 |
Make up a temperature probe carrier... |
 |
.. that will sit in the manifold. (Not fouling the end evacuated
tube!) |
 |
Manifold and tube. |
 |
Checking the delivery... |

Site of The Final Destination. (Roof faces SSE, picture

Removal of tiles. This is the Planning and seeing what's
there stage. Battens are lifted and the flexible stays are sited over
a rafter. This sites the right-hand runner over a ridge in the tiles.
We will not be so lucky with the left-hand runner. The intended rafter sits
under a tile trough - so a 2" sleeper will placed next to that rafter, and
the left-hand stays attached to the sleeper.
|
 |
Grinding a slot. The stay will now protrude between the
tiles without making the tiles sit unevenly. |

& "Nice Nick". (I'm the one in the blue top sitting on the rug.) |
 |
Probe in situ. (Note the deliberate error! - The probe should
be entering the manifold, not the pipe.) |
 |
Stop talking and get on with it! |
 |
The frame bolted down! - After 10 hours work! The right-hand
sits over a rafter and a line of tile ridges - that was easy to line up!
The left-hand rail was more of a problem. This sat over a rafter that
did not line up with the tiles' ridge. A cheek extension - a 2" by 3" timber
- was attached to the rafter - and the rail attached to the extension. (This
involved a morning's time hacking out a noggin, opening up the felt to slide
in the new timber, bolting it in, replacing felt....)

 |
And on the sunniest day in three weeks, the tubes go in!

Andrew tries an Arty Shot.. (Whatever, the rafter and rail
alignment can be seen. ) |

The first morning's results! The sun hit the panel at 7.30
GMT. Peaked at 11:15 GMT. Rain PM!
