Squirrel Works - Space Ranger
Contributed by John Lee
Construction: I started off noticing how thin the balsa for the fins is. The instruction says that all but the root edges should be rounded. With me and my aggressive clumsiness, that means trouble. I decided to try and seal/strengthen the fins with CA. I drizzled thin CA onto the fins and swished it around with some card stock. I did this over wax paper, thinking that I had read that is a good idea. It wasn't. CA will stick to wax paper along with everything else. My fins now have little star tattoos since it was Christmas wax paper. I have the same tattoos. The fins are stronger now, though. Sanding improved things but I decided to go ahead and seal the fins with Elmers before going any farther. Assembly of the rocket itself was not too difficult. It began with the motor mount. A thrust ring was to be installed with the aid of a provided engine space. Before installing the thrust ring, I cut a little notch in it so that I could provide a Kevlar® shock cord mount attached to the motor mount instead of the provided trifold. After the notch was cut, I tied the Kevlar® around the ring and then inserted it as per the instructions The next step was to cut out the wrap around fin guide. It matched perfectly and the fin lines and lug lines were marked. The fins were attached with CA but I added a step. Using a safety pin, I perforated the root edges of the fins and the BT along the fin lines in order to form "rivets". Then CA was used to mount the fins and the launch lug. When the fins were dry, they were filleted in the standard manner with yellow glue. I had some trepidation about the canopy but it turned out to be fairly easy. Its simply a matter of cutting it out with a razor knife and then gluing a single tab. That part did not bother me. Mounting it and getting it faired did. It turned out to be not much of a problem. I used yellow glue and stuck it in place. It seemed to follow the contours of the BT fairly well. The one thing I am unhappy with is my alignment. I could have gotten it a tad straighter if I had noticed in time. While the glue joints were setting up, I tied the elastic shock cord to the Kevlar® and installed the eye screw in the balsa nose cone. The screw is held in place with a bit of yellow glue. The rocket was then ready for finishing. Finishing: The rocket was given 2 coats of white primer and was then wet sanded with #600. After that, I began spraying on thin coats of gloss white. I used a total of three coats. Some of the other reviews have made mention of the difficulty of applying the decals. Long and skinny decals are always more difficult that ones with more unitary aspect ratios but I had no real trouble with these. I don't credit this to my skill. Instead, I think it is a testament to the high quality of the decals provided. There was no tendency to tear and they went on great. I wish all decals were like this! I think this is one of the best looking rockets I have constructed to date. Construction Rating: 5 out of 5
