I just put together this quick video tutorial on building spinners as well. It is a pretty big file so you dial up users may be in for a wait on the long download, sorry. I plan on updating this outdated pictorial on building spinners using rvrfshr componenets instead of the now defunct MorTac stuff soon.
And no complaining about the Dave Edmunds soundtrack, thats is some killer vintage stuff from Dave! If you don't like it you can turn your volume down.
