Watched that video, and although interesting the presenter doesn't really know what all the bits are either, so im still in the dark, and as for finding info on the net it's a slog, also im having snags uploading pictures I keep getting error-200 for every image I try to upload so im unable to show you each part that im having snags with identifying and finding the correct use for them.
So my first question is, whats a bell chuck and what's it used for?
