"Highly recommended tool"
Eric F. (Arizona)
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!

"A Must-Have tool for all Estes Rocket builders"
jayjuice7 (Arlington, TX)
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!

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

"Works OK"

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