Cheers Hood, I have a e/stop button on the front of the machine so will use that, It's in a position which is easy to get too. indeed everytime something falls of the machine table it catches the stop button on the way down. Once again thanks for the advice, much appreciated. I know its not good for the UK but don't know how they do it, the total cost of the unit from Hong Kong was £25 which included air mail, It arrived 11 days after I purchase it on ebay. Mind you the warranty is only 1 month. Jim
