Step 3: 1. Assemble The Engine Mount

The following steps detail how to assemble the engine mount.  The engine mount is what attaches the rocket motor to the body tube of the rocket.

1.1. Mark three lines on the engine tube at ½ in, 1 ¼ in, and 2 ½ from either end of the tube (This end will be the bottom).

1.2. At the 2 ½ in mark, make a 1/8th in slit in the Engine Mount Tube with a modeling knife along the circumference of the tube.

1.3. Apply glue all the way around the Engine Mount Tube on the measured 1 1/4th in mark.

1.4. Insert the right angle end of the Engine Hook into the slit made in (1.2), lay the hook flat against the tube and glue.

1.5. Slide the Mylar Ring over the Engine Mount Tube and Engine Hook and onto the glue line.

1.6. Apply glue to the inside of the Engine Mount Tube on the side opposite of the Engine Hook and insert the Green Engine Block, open end into the tube.

1.7. Cut out the Centering rings.

1.8. Slide the Centering Rings over the Engine Mount Tube and align the ring with the notch at the ½ in line, and the ring without the notch at the very top of the tube.

1.9. Apply glue to both sides of both Centering Rings at their aligned positions.
<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!
