Thanks for that Steve. Ask any question regards of how to do a certain job and you'll get different answers proportional to the number of people asked. I was lucky in the respect that the toolroom I started my hingineering career as the youngest of five in the department, next youngest was 55. Boy, did they know their onions. In seeing you do something "Dodgy", first warning would be a shout. Second offence would be a kick up the posterior and third a piece of 4 x 2 on the back of the head. I never achieved the "Honour" of stage two or three and they managed to make sure I didn't suffer from some of their "Battle scars". Learned more under their collective wings than the "Book" ways and Tech.
As a true Yorkshireman, the words "It only cost a pound" means you WASTED 66.6 pence!
