I just wanted to update this thread and say that the wicks arrived very fast and they were perfect. I measured for my Necchi wheel and cut it with a single edge razor blade and it was a perfect fit. I wasn't sure how much oil to add to it but remember someone saying about 12 drops along the whole wick so I did and now the hand wheel turns great.
The woman that takes the phone orders ( because I had questions before buying) was very nice and they do not have a minimum. If you need wool felt I totally ( yes I am Californian ) give my stamp of approval for McMaster-Carr.
