| Construction 8 - Installing the Roof |
|
Putting the metal roof panels on to the roof frame was only
possible by raising the frame off the floor on some old milk crates.
Whilst much of the roof panels are held on with self tapping screws, many of the
fixings were nuts and bolts. This required one above and one below the
roof. Thus putting the metal roof panels on to the roof frame was only
possible by raising the frame off the floor on some old milk crates. I had
a really sore back for days after doing this as I was the muggins under the
roof. The resulting roof is quite rigid but pretty heavy. Still,
it's a lot lighter than a wooden roof would be.

After installing the roof, I quickly realised that the
wood used for the roof carriage was not really thick enough for the job, evident
by the roof sagging in the middle. I thus had to put in a strengthening
piece of wood across the front of the roof (A). By my calculations, there
won't be enough clearance on the back rail to add a strenghtener and still clear
the scope when opening and closing the roof; so I had to come up
with another solution for the back rail (see later). This picture also shows one of
the roof carriage lockdown mounting blocks (B) and part of the roof lockdown
system (C).

I mounted a simple handle mounted on the back rail of the
roof carriage to make it easier to open the roof.
