KFm 1 and 2
First, find the wing chord you want and make a dot on both sides. Now go up by half that and make a dot. Cut that piece out. Draw a line a quarter of an inch above and below the five inch mark. Score through the paper on those lines and peel it off.
Put your yardstick on the five inch mark and start bending up the shorter side.
Once you can bend it all the way down, apply glue and hold it down until the glue is dry.
Put a bead down the back part of the step and squeegee it off with scrap foam.
That is it for the KFm 1. Just flip it over for a KFm 2.
KFm 3
Do the same thing as the KFm 1 exept go up half an inch instead of a quarter. You still go down a quarter though. Peel the paper up and fold the shorter side again.
Cut a piece 75% of the wing chord and apply glue to it.
Line the front up with where the paper starts on the larger side. Then, apply glue to the paper of the shorter side and hold both pieces until they dry. You can put a bead of glue down both of the steps and squeegee the excess off with a piece of scrap foam.
That is all for the KFm 3.
KFm 4
Cut two pieces the length of your chord. Mark half way on one of them. Draw a line half an inch above and below that point. Score the paper on those lines.
Put your yard stick on the middle point and bend the foam all the way down.
Put hot glue on both halves of that piece where the paper is. Line the larger piece up with where the paper starts and fold the other piece over.
Put a bead of glue down the back part of the step and squeegee off the excess. Once it is dry, you can do that to the other part too.
Now your done!
