  1. Martin Boothe

    all of these positive reviews. they must have a different tool. the flimsy fin holders do not hold the fins in the proper position! after several tries, the only good use for this tool is to hold the rocket for painting! it does not hold the rocket straight! it does not function as advertised!

    Good item- very useful

    Works with 3 or 4 fins. It takes just a little bit of practice to get the hang of it, but after that you’re good to go. Holds the body tube in place while you simply attach the fins. The clips then hold them in place on the guides. Works with many different fin shapes.

    Fast is Right!!!

    With this I am able to glue all the fins on at once and I know they are straight. I highly recommend it!

    Gotta have

    Really excellent building tool.

  5. Juliet

    Useful for aligning fins

    This makes it much easier to align fins than it would be by simply guessing- this makes sure that the fins are firmly attached to the rocket. The only thing I would mention is that you have to be careful with taking the rocket out of the alignment system after the glue sets- the fins can sometimes become glued to the alignment system.

    Where was this thing 30 years ago. Me and my friends used to struggle getting the fins just right and the Fin Alignment Guide takes all of the guess work out. I LOVE IT!!!!

    Easy to use

    This is a very helpful tool that’s easy to use and makes building a snap. Well worth having.

    Nice Concept

    Looks like a great idea. A bit faster and more versatile than the built in tool of the “Tube Marking Guide” set. It would be nice to know what size tubes it can accomodate.

    I tried several other ways to mount fins but this is by far the easiest. Straight fins and exact placement on your first try is possible.
