Well, I'm trying to start up again with my laptop. The art program just isn't as good as the one I lost, but I managed to cobble together a SHADOWTRAK profile. I may try and do a few more, but in the meantime...

The wheels are rubbish I know, but again I blame my 'tools' for not allowing me to do concentic circles. Everything has to be done 'by eye' so that explains why they aren't as round I'd like (and the hubs are a bit off centre too!). I also had to reduce the size a bit to fit it on this forum. Things are a bit clearer on the full-size version.
