Model Rocket Builders Marking Guide

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.

I've been away from model rocketry for many years. It was always a challenge to get fins spaced right and straight. I've used the door frame for years. Pencil marks all over the wall and not being sure the door frame is even straight. This is an awesome tool. It is easy to use and does a bunch cool things for the rocket builder. Many who review it say it is a must for builders of custom rockets. I say yes it is a necessity for that but it is needed for ALL rocket building; kits, modifications and customs. It is a no-brainer...get one now before you start on your next rocket!

This works fine, especially for smaller tube sizes. For larger and longer tubes I prefer to a piece of aluminum angle from Home Depot.
