Out of the planned hold, for about a week now. Minor diversion to get a new rocket designed and built in time for this Saturday’s LUNAR launch at Moffett Federal Airfield.

Despite the diversion, work continues on the Saturn V. The primary structure of the lower section of the rocket is completed. Along the way, I learned a nice technique for making tube couplers for arbitrary tubes (assuming you have enough extra from a spare tube): section a piece of the tube so it just fits inside “itself,” retaining the tab that’s extra, and use the tab as the bonding surface for the two pieces.

Filleting the forward centering ring of the motor mount proved a challenge: it’s very far down in the body tube, and tough to reach. There’s likely more glue on it than really needed, but I’d rather lost 10′ of flight altitude and keep the rocket together.
