Nick,
Cat amongst the pigeons
The ones I've got from M&P have been coated with some sort of protective goop, but it's not really a lubricant
per se. I wrap it up with a strong bag, wear gloves and cut the binding wire off.
Boingg!
The spring can then be cleaned with IPA and lubricated both sides and wound into the barrel, keeping goggles and gloves on.
I've never needed a winder except on the wide springs on fusees.
A sharp tap onto the bench will settle the spring into the barrel so the arbor and cover can be fitted.
For this size of movement, car engine oil is as good as anything on the spring, arbor and ratchet.
