Tonight I started on the SNARKY project. First I used 400 grit to sand the “Balsa” more like Basswood fin pieces before removing from their laser cut housing. Quality laser cutting here by the way! Then I layed out the left and right wing sections and top fin pieces making sure I had all the angles right. Then I used t pins and wood glue to create the sections. I will sand in airfoils to all fins and will cover with 3/4 oz fiberglass cloth and thin CA glue. Next I moved onto the motor mount. Since I’m using a motor retainer (Estes 24mm) I don’t need to use any hooks or blocks. I dry fit the entire mount to fit the retainer and also made the shock cord mount in a loop fashion dividing the strain to both sides of the rocket. Next I started by gluing the Aft CR in place and went ahead and glued in a green CR to add more strength to the joint. I moved to the front CRs using the same procedure. The front CRs each had notches cut for the shock cord to become captured. Then I knotted the shock cord down and secured with more wood glue. Finally, using JB Weld high heat epoxy I glued the engine retainer to the aft portion of the motor mount. I had to add about two wraps of regular masking tape around the MMT so the slightly larger retainer diameter would fit better on the MMT.
