In 1970, we had to hand cut 36 pieces of balsa to assemble an Orbital Transport!
If you ever have to cut balsa from a cardstock template, be sure your (sharp) blade is at a 90 degree angle to the balsa sheet. The illustration is from the yellow pages in the 1971 Estes catalog.
After gang sanding -
Check the corners being sure everything is even and square.
The root edges of the wings were glued together on a sheet of glass.
Weights were set on the top while the glue dried.
I do remember tracing out the fins onto the balsa sheet and cutting out the parts on my first two model rockets (Astron Alpha and Astron X-Ray) back around the mid-to-late 1970s.
ReplyDeleteHi Naoto,
DeleteWhen I received my first kit (The Centuri Javelin) in 1969, all the kits had balsa sheet with trace and cut templates. I didn't start seeing die-crushed balsa until the early 1970s.
