Red River Rocketry Starliner DST, Part 4, Shroud Cutting and Forming

The engine mount is glued into the BT-50 tube.
It is slid in until the 20/55 centering ring butts up against the tube end.

The instructions say to apply glue inside the tube and around the lower 20/50 ring.
Slide the mount in place then twist it at the end of it's travel. This will even out the inside glue line into an even fillet.

The shroud was scanned and extras printed.
This will be a doubled or nested Super Shroud.

There is quite a bit of exposed shroud around the engine mount and I wanted it to be stronger.
A hard landing could dent a single layer shroud.

For a better fit around the launch lug the shroud was cut as shown in the picture.
This cut allows the open top slot to fit tighter around the back of the launch lug.

On the left is the single shroud cut on the black border lines.

On the right is the shroud cut as shown above.
Two stacked, nested shrouds are used. The inside shroud overhangs the bottom and will be cut off after the glue dries.
