Recently Chris finished a model called Orbital Transport Laboratory. Here the link to his building blog: https://modelrocketbuilding.blogspot.com/search/label/E Orbital Transport Laboratory
It was first introduced as a Design of the Month winner in June of ’71.
The rocket was also on the cover of the 1972 Estes catalog:
I thought this would be a nice and easy project for a partial 3D printed version.
First step was to design and print the engine nozzle:
A centering ring and an engine block was also designed and 3D printed. Here the parts:
Next step was to cut a BT-60 body tube to 5 inches in length. I then glued the centering ring in the body tube. When the epoxy was cured I drilled the holes that hold the fins in place.
I also glued the engine block in the engine tube:
Then the engine tube was glued to the centering ring:
Next part will be the balsa fins....
