My main problem with the processor build has been being here during the day, as the grinder is really very very noisy and the neighbours would not be happy! I have to do it in the garden as welding in the shed would result in large amounts of fire (pretty much every time I use the MIG, something catches fire).
Plus I've been working on the extension as priority for winter (needed everything ripping out an insulating, which is done, just needs wiring and plasterboarding!)
Actually, when the missus isn't here... I could do the welding in the extension... currently has a plain concrete floor - hmmmm
