My personal view is tool technique really counts,it saves so much time,you spend less on abrasives and always end up with a better finished product,I was turning at home for about 8yrs before I joined a club and thought I could turn,I got a shock,I couldn`t after all,the first club I belonged to the members their showed me tool technique and I advanced in leaps and bounds,we all ave bad days at times but it gives us a chance to review our technique and make it better.When it comes to showing people,I don`t think we should say they are wrong,but just suggest a better way of handling the tools to get a better finish,just my view,regards,
Eric.
