After the doors comes the sliding hatch.

A 2ft square hole is cut in the roof.
Before I did this I felt it would be prudent to cut and half tie a tarpaulin in case it rained. In the end, it didn't.


The hole from the outside


40mm Equal angle makes up the runners and centre stop.
The straps help get it perfectly square, the angle at the front keeps the front at the correct width.


Welded up (still only tacked at the back), looking good.

The next job is to create a sliding cover for this. I have a temporary wooden one on there now for security, but I'm going to create a metal one shortly. Need to get some brass strips cut down too for the runners. All the welds need prettying up too.
