George,
You've hit it on the head, he wants to wind on 3 different colours, the upright is not yet glued in to allow it to be more easily wound. He's a fisherman so knows how to load a spool.
As for the electrics, I'm easy either way, me or him can wire it. We are both exREME. Yes I'm aware of the electrical regs that require PAT testing. That is something we can sort out through work, we have the technology, and can get it tested.
