Because
I cannot weld aluminium we had to get somebody to do the welding
for us. We had some ridiculous quotes like R6,000 for the welding
only. Finally we had an arrangement with two gentlemen from Langebaan
that we will do the cutting and fitting and they will do the welding
for us for an undisclosed amount. They gave us a good discount
because they want to start building canopies but needed the experience.
So
we got Cobus and Charl to do all the Aluminium welding. (Click
here for their details.)
We
decided to use 38x38x3mm square tubing for the frame. We decided
on this purely for strength. Niel will be adding a roof top tent
to his canopy soon and he is a big guy and myself will be standing
on my canopy when taking photographs. That is why 38x38x3 seemed
like a good strong option.
First
we welded the bottom frame, the size of the load bin. We both
have 1998-onwards Hiluxes. Niel a 2004 KZ-TE and myself a 1999
2700i Hilux.
The load bins are the same size so we could build both canopies
at the same size.

The size of the base frame is: 1,410mm long
and 1,530mm wide
This is where we made our fist little mistake. We
built the base frame the same size as the loading bin. Only after
everything was finished we realized that it should be slightly
smaller. The reason for this is that if it is the same size there
will be very little space between the canopy and the cab at the
front. If you install a window, the window rubbers will touch
each other. In the picture below you will see that we moved it
backwards about 10mm in order to increase the gap.

Thus on the first canopy we had to cut the frame,
remove 10mm and re-weld it again. The measurements I gave above
is the correct size. It will be best to always measure your own
vehicle as the measurements might vary slightly between vehicles.
