Cutting Out Fins when Building Model Rockets

"Next in preparation of model rocket is fin preparation. When you prepare fins they come in on a balsa wood, sometimes balsa wood; pieces of planks if you will and they are precut outs for you to score out the fin. As you can see the fin design here is basically kind of a rectangle and with a, with a triangle appearance. To cut out the fin you simply take your Exacto knife, carefully scoring out the fin breaking tabs in the balsa wood to be able to pull; separate the fin from the balsa wood easily, like I am doing now. You'll thong each side of the fin being very careful not to cut into the fin and cause an error. After you cut the fin; and by the way using a piece of wood or, or; or something to cut on is good so you don't ruin surfaces that you may want, you might care about. You then break the fin out of the pattern; sometimes you have to re-cut because you didn't get it the first time, like this. This is thick balsa wood by the way; which is good because it makes the fin last longer for a rocket. And you break the fin out like so; and after doing this you get a fin. Now do that three more times."
