Well,thats it up. Took about 4 hours to complete, but not a reflection on Asgard, the construction took about an hour and half and went together quite easily.
The rest was making it long enough to get the longtail cargo bike in, involving cutting hole big enough to get the back of the bike through. Was going to get a metal extension fabricated to fit around the hole/bike but discovered an old plastic box that has been sitting in the garden was the perfect size for the job once bolted in place.

really pleased with how good it looks.
