First, construction of the Forte rocket by LOC |
|
|
The LOC Forte, my first LOC rocket and my
first epoxy rocket. I choose it because its 3" diameter allows for a range of cameras
to fit into the payload section which was purchased separately and not shown in this pic. |
Top end of the motor mount tube. The tube is
22" long and uses plywood centering rings. My first plywood ring and fin rocket. |
|
|
The aft centering rings uses "T"
nuts to hold the # 6 screws which hold the clips which retain the motor (top view). |
Looking down from the nose cone end of the
body tube, you can see the top of the motor mount/ring assembly. The ring was 16"
down. How do you get epoxy 16" deep into a tube without making a mess? See below. |
|
|
Notice that now you see 4 screw posts. The
reason is I mistakenly epoxied the "T" nuts while the screws were in. The screws
ended up being epoxied and actually broke when I tried to take them out. Didn't know epoxy
was that strong! |
Here is what I used to epoxy deep inside the
tube, a paint stirrer. Mix epoxy on the flat side, put inside the tube, turn over and
presto, epoxy right where you want it without wasting alot of it. |

|
First fin gets epoxied on. I love these
pre-slotted tubes! |
All four fins on but no fillets let. |
|
|
Closer view showing fins without fillets. |
Epoxy fillets added. I got card stock, mixed
epoxy on it and then place card along root edge and let epoxy flow down along the joint. I
then tilted the body tube back and forth to let the epoxy smooth out. Didn't have to use
my fingers. |
|
|
Next the launch lug is epoxied. |
The cord that ties to the shock cord is
epoxied deep enough into the tube so the nose cone still fits. As you may see, I got a
little too much near the top and it needs to be sanded away before the nose cone goes all
the way down. |

The finished,
painted Forte. Now on to the payload section. |
