Excellent solution for Fin Alignment.
By dvmanning October 18, 2012
I have used this alignment guide for several years and find this tool an envaluable addition to my model rocket took box. Fins can be attached to the tubes with ease. You will need to apply your glue to the fin surface being attached to the tube and on the fin line itself, allow the glue to get tackybefore attaching the fin. The time frame for getting tacky will depend on the type of glue you are using. This alignment tool works everytime with the 3 and 4 fin alignments. It is very important to read and understand the instructions for use of the tool. The tool is easy to use. Since the alignment tool has both the 3 and 4 fin configurations, it would really be nice if Estes rockets would design a fin alignment tool for the 5 fin configuration. I work with a group of boys that are building their first rocket and this fin alignment tool has been very useful and timely. David

Quick and easy and fairly sturdy
By kgladstone October 21, 2012
I had the old Estes metal fin alignment guide about 30 years ago. That one was rock solid -- more sturdy and precise than this one. However, this one does have some advantages, such as the included engine spacer for centering your rocket. And it is a *lot* easier and more accurate than doing fins manually. I did four stars because it's not quite as solid as the old metal one. But it still extremely useful, and recommended for anyone who plans on building more than a couple rockets.

Nice product for fin alignment
By kristian October 15, 2012
i ordered this unit after making some rockets by marking them with a doorframe. This makes the job very easy. you dont need to mark them at all. just place the tube on the guide and atatch the fins. very easy. it can be smart to attatch the launch lug before you do the fins.

Simplifies attaching fins to rocket tubes
By Fud91 February 12, 2014
The Fin Alignment Guide by Estes gives you great quality fin-alignment very easily. Make sure you read the enclosed instructions. If you've ever used the fin-marking guide and a door jam or some other straight-edge, you know that lining up fins and getting them to stay in place can be a bit frustrating. This tool gets it right the first time; just apply glue as you would normally, attach the fin to the tube, clip the fin to the guides and walk away. Wish I had this 30 years ago when I was building rockets as a kid!
