This isn't much of a news item and is only included for completeness.
You might recall that the butt strap that joins the two halves of the cabin roof turned out to be a few inches too short.
I made it that way, and until now I couldn't understand why. The manual clearly states what to do.
However, I remembered that I followed the photos in the manual when making the roof. And the photos show that the builder made the same mistake!
So I of course did the same thing ...
Anyway, here is a lump of lead holding down the missing piece of butt strap while it cures.
