Today we headed to Cambridge Precision, our local machining sponsors. They are making all of the coupling rings for the 3-stage Martlet 1 rocket. We visited their R&D department today, to see the first version of the parts. After the anodisation process, some of the parts were no longer a sliding fit, so sadly we had to remove the anodising layer in some places.
Tomorrow we’re heading back to Cambridge Precision to finish the match-drilling and match-tapping operations on the coupling assembly and bulkhead assembly, which links the motor and parachute sections (as shown below).
More photos will come in the next few days, as the parts are completed. Many thanks to Colin, Pete and Steve over at Cambridge Precision R&D, who have put these parts together so accurately for us.
