PML Lunar Express Build, Part 3, Engine Mount
Compared to a LPR rocket, in MPR the engine mount uses beefed up parts. Plywood centering rings and a heavy engine tube.
The centering rings are epoxied onto the motor tube with the shock cord strap slots lined up.
The black shock cord strap is epoxied flat against the engine tube. I pencil traced around the strap before applying any glue. This gives me an accurate outline of the glue areas.
I look at the interior assemblies as good practice for the outside surfaces. Using Epoxy is like assembling a rocket with running honey. It goes everywhere! Gluing the strap and centering ring fillets gives you a chance to see how epoxy flows and runs.
