Build log 2014-12-17 : Locking tabs

No big progress. Simple locking tabs were printed and "acetone-welded" to the main hatch/wheelhouse floor in order to lock the hole superstructure to hatch coaming.

Those tabs work surprisingly well (first attempt!) and positively lock the main hatch in place while still keeping everything easily (no tools) removable to change the battery.

Push knees were also "welded" in place.
