One of the most challenging aspects of building precise model rockets is to get the fins aligned correctly. This fin alignment guide from Qualman Rocketry solves this problem by precisely holding the fins against the body tube as the glue dries. This laser cut guide is sized for a BT50 body tube model rocket that has 3/32 inch thick fins that are either 90 or 180 degrees apart. Can hold up to 4 fins at once and is also designed to hold the launch lug, so all of the gluing goes quickly.
