Chains or Not

Just bringing the pieces together temporally to see how it all looks. Just realised that these chain should be taught as the platform would have been raised from inside the building. I think. As you can see from the photo I have a problem with the two parts not being level, looks like some jiggling is called for.

(comment welcome)  

Change of plan. No balcony but individual platforms each with its own chain hoist. ( I hope)
