I print off the instructions for reference for each pen which has basic information to start. I highlight the bushing number and bit size plus I add the replacement tube number and the length of the tube. I check the tube length while trimming to length. All this saves looking at the chart every whip stitch. Not a computer expert but stumbled on the setting to print both sides. I keep the instructions in a hanging file in alphabetical order.
