Regarding the shelving, there is enough in the space now to make a 2m run, and a 1m run. I think the 2m run could fit very well to the left of where the Hammond organ is living, between the two supporting props.
The 1m could go in the dark corner where some mops are. The 1m run would need some fasteners (holes need drilling for nuts and bolts) to hold the bottoms of two of the legs to the base.
If no one has problems with the 2m run, I'll assemble it between the posts Wednesday night.
Then I suggest we throw out / weigh in for scrap some of the other stuff that is now surplus to our requirements.
Then we can have a list of storage locations, to be used in the asset database (Airtable, see other thread).
