Step 4: 2. Preparing the Fins

The fins are what help stabilize the rocket in flight.  The following steps show how to cut and sand the fins to prepare them to be attached to the rocket.

2.1.Carefully cut the Model Rocket Fins out of the Laser-Cut Balsa Sheet.

2.2. Sand the rough edges of the fins to remove any burrs.

2.3. Align the sides of all four fins, hold them together and sand the base of the fins (This just ensures that the fins are flat where they attach to the rocket).
<p>please tell me , i can do it in my stem fair</p>
<p>is it gonna fly</p>

I remember making a model rocket when I was in Beginner Shop in Jr High, we made the tubes by wrapping Gummed Paper Tape, it worked very well. We made all the components in the shop and then went out to the field next to the school and fired them off, most of the rockets that the class made worked great, a few had some issues with flying straight. It was a learning experience that I really appreciated when I played with some of the Estes rockets later in life.
Cool! <br>I like the colors of the chute :) <br> <br>Also even as a non-rocketeer, i understood the basics and think i would be able to pull off a feat like this without too many fails in the process. <br>--&gt; Good 'ible! :)
GREAT job on this buddy...however, here are some tips...if you take the body tube, and place it in a smooth corner of say...a door frame or window frame, you can draw one line, and then standard common sense kicks in after one glues in the first stab fin. for thes stab's i have found superglue works wonders...3-5 coats will ensure the fins dont go anywhere... you can also sand than and make a lovely and fluid &quot;fairing&quot; joint. you can do the same with wood glue (which in my opinion works better as you are glueing 2 wood materials together, it will create a super bond) but the tradeoff is that you will have to wait for the glue to dry and cure...superglue is quicker, but its easy to make a mistake that could be potentially detramental to the FULL performance of the end product... <br> <br>as far as these kits are concerned, its hard to mess them up though. the real hazard which is agreeable is fire upon takeoff, but this is unlikely anyways. and even if it desintegrated upon t/o, it would end up sommersaulting in mid air safely from spectators as these are NOT high poweres rockets...it would be more of a concern if it was powered by anything bigger than an E motor. <br> <br>Overall though, lovely project!! i enjoyed working on it!
