Sorry can't remember Paul's definition. I know demos range from good to bad, all demonstrators at some time have an off day/evening when everything goes wrong, the trick is to overcome your mistakes and put them behind you and carry on with the demo.
I agree about working with the cameraman, but when you are stood out the front demonstrating and being paid for it you are acutely aware that you are being paid for every minute and sometimes the camera gets forgotten.
I also agree about having a wider audience, luckily I don't have a problem there as I am quite loud naturally.
Finally Tony, cringing when a hand is applied to rotating wood? woodturners have worked like that for 100's of years, touch is part of the arsenal of tools at my disposal and anyone that has seen me turn will tell you that I am constantly touching the wood and I know I am the H&S guy who should be telling you to stop the lathe and saw your work off but that doesn't happen in my workshop, I part off completely with the piece cradled in my hand so I have to touch it then aswell. During a demonstration I demonstrate how Iwork and howImake various bits and pieces, it should not be a sterile demo where every aspect is perfectly carried out, if it was you would only have to see one demo to learn how every one does it and then there would be no individualism left in turning.
