I've played with making fins with 24lb paper in the past when down-scaling carded rockets below BT5. Using 24lb paper I could see the cereal box images through the paper on the fins. I then started using white mailing envelopes and painting the inside, which was brown, with white primer; I would then rough up both sides. I can make several rockets with that one piece of painted mailing envelope. <br /><br />Measuring carded fin thickness, using a light touch with a caliper, 100lb paper fins are about 1.2mm thick and 24lb paper fins are about 1mm thick. <br /><br />I’m also finding out, measuring just now, that while cereal boxes are about .5mm thick my mailing envelop is .73mm thick. I’m feeling much better about using just one sheet of 24lb paper for my fins. This saves on ink too, which I print using the highest quality settings. <br />Anonymoushttps://www.blogger.com/profile/02743996762777645095noreply@blogger.com
