Thats a great piece of info Adrian. That will be an immence help when making cuts! If you should choose to thread cut, just take a length of thread, wrap around a piece of stick or something similar, do the same to the other end, then just start pulling back and forth, allowing the friction to cut through the plastic. You'll fast learn how fast and how much pull preasure to put on it to keep cutting smoothly. As I said befor, it will likely break a number of times, (always does) but it should give you a good clean cut in the end. Good Luck! Can't wait to see the end results. I'll be starting mine soon... I hope. Take care!
