Thanks to Tudor being in town I've been a little bit more active on the project.
We started out by reinforcing the lifting handles as they were making very bad sounds if you started to lift by only one.
We added a poplar plate around the handle to try to distribute the load.
Then we returned to the engine and fan mount. We finished assembling everything and fit checked the fan. After which we glued and screwed down the base parts.
Part 1:
Part 2:
One thing to note is that of the 9 toggle bolts we used 2 failed to twist the toggle correctly. So we had to reverse course and remove the whole assembly to replace the toggles.
