That's funny. I'm a pattern maker in the arrow space industry. I got laid off early 2009 and started doing side jobs. I started my own company about two months ago and started automating some machines for an air filter company. Your suggestion to turn the roll down to 1.9099 is what I came up with also to make it easier. The problem I had was that they hired me to retro fit the design they already made for that project. In the future they will consult me first then I can make the hardware to fit the software better. thank you for your reply.
