Hi Lee, try Martin Taylor oop t'north
How Do,
I have not programed the machine to case clearance, as i only get asked about it once in a blue moon!, so when i have to do it i usualy do it by hand.
May be now cases are getting more expensive i should set the machine up to do it.
Its not a dificult job, just time consuming.
you can give me a call at the workshop if you like, the numbers on the web site.
