Rocketarium Hydra Sandhawk Build Part 2, Sustainer Engine Mount
I sanded off the brown from the flat surfaces of the centering rings.
Don't sand the edges! The fit in the BT-60 tubes is pretty good.
There's a small "gotcha" in the instructions.
Wait to do the tape wrap until the rear ring is 1 1/2" from the rear.
The tape moves from the center of the tube to the forward end in the same step.
TIP: If your ruler markings are flush with the end -
Use it to check the ring placement length from the tube edge. Here I'm checking the 1 1/2" distance.
The square end of the ruler will help square up the centering ring so it is 90 degrees to the line of the tube.
Place your ruler end at a few locations around the centering ring as the glue is setting up.
