It went well, with little or no drama.
Here is a view from starboard of the roof glued in place and firmly buttoned down with plenty of temporary screws.
You can see that the roof is quite considerably oversized at the front, almost as if the original design had a longer cabin but the roof panel was left unchanged!
It's no matter - it is actually very reassuring to know that there is plenty of waste material around the perimeter.
The temporary screws into the carlins in the hatchway were insufficient by themselves to hold the roof down tightly, so I added some spring clamps to assist. As here.
When all the screws and clamps were in place I cleaned up the squeezed out epoxy on the outside, and then hopped into the cabin to do the same inside.
Lastly, I pulled out all the blue tape which was protecting the interior of the roof and the Dorade boxes from squeeze out. It worked really well, as this pic of the port roof shows.
Luckily I took photos before the glue had cured, when I noticed that a strip of blue tape was still in place. So I quickly peeled it off.
This is a view of the starboard roof inside the cabin.
Next job is the seatback tops ...
