Model Rocket Builders Marking Guide

If you build lots of Estes rockets you need this! With these guides you will no longer have to cut out the tube marking guide from your instruction sheet and this is more accurate as well. Drawing a straight line on your body tube with the guide is much better than using a door jamb, just be sure to hold your tube carefully while you draw a line along the slot so it doesn't move. After purchasing and using these guides you will wonder how you ever assembled rockets without them!

Easy to use and accurate. Simplifies measuring and marking tubes for proper alignment and placement of lugs, fins, tube-to tube configurations, etc. Way easier than trying to wrap paper around a tube to mark it for fin placement, or to use the door-jam method for straight lines. The pencil marking guide to mark around the circumference of the tube is great for setting up a cut line, or other accessory placement.

This is extremely helpful in building. If you want a more sure way than your door frame, this is it.
