hello Andy, I thought I would add my points as a professional turner/demonstrator.
I do not make or sell DVD's but I am still reluctant to a certain extent for people to film me,my reasons are this: Sometimes even professional turners make mistakes when demoing and I for one would not like to see my mistakes put on you tube as this could affect whether I get bookings from other clubs. This would then impact on my earnings. Also, in these days of litigation, if someone injured themselves using a demonstrated technique it could cost me money.
As regards handouts, I used to do a handout but as Pete has already said sometimes you adapt your demo to the audience so the H/O is not pertinent. Also, after spending many hours producing a handout it is demoralising at the end of the evening to see them spread across the floor and yes it is time consuming and expensive when most clubs want cheap demonstrations and sometimes all they dowant is to be entertained.
As John has already said, if there is anything you need to know send an email, I for one do reply to the best of my ability.
What would be better is for the audience to get involved with the demonstration, ask questions and get the demonstrator to go over things again if you are not clear. It is not an easy thing to stand in front turning and wonder if there is anybody paying attention, especially when there is one or two people rudely talking when you are doing your bit.
The other thing is I am sure, like me, most demonstrators ask what you would like done,the reply should be more positive than "anything you like" because we can do most things but want to do what is of most use/interest.
Have to stop for now, thunderstorm.
