Thanks both of you for the tips. Now I see which side of the skewer is going to possibly stick out I can why it's important to get it trimmed down enough so it's at least protected by the nut from a thief with a cordless Dremel (had to look it up to see what that is!).

Fingers crossed there won't be anything to cut off AND that it doesn't turn out to be too small for my wheels. Going to give it a try tomorrow. Hopefully I can pull this off properly.
