Description

These laser cut centering rings are made from 1/8 inch birch plywood, and sized to mount a 29mm motor tube in a 56mm (BT-70) airframe tube. Rocketry Works' unique perforation pattern allows users to knock out holes for shock cord or for an eye hook, and also a space to slide the forward centering ring past a rail button anchor inside the airframe tube.  If you don't need the cutouts, you can simply fill the laser cut perforations with glue or epoxy. Some light sanding may be needed to fit the motor tube or airframe tube. Sold as a set of 2 centering rings.
