Re: wrapping female ferrules
You just need to wrap the female portion of the ferrule like you were putting on a guide. Get the thread as close to the end as you can. Rule of thumb is the wrap should be 2 times the diameter of the ferrule, but you should check with the manufacturer to see if they have requirement to keep the warranty valid. There is one manufacturer who doesn't require ferrule wraps, but I like to see them just to be safe.
Better to be an active environmentalist than and environmental activist.
