Lawn Dart Rocketry SLAT/S Build, Part 6, Fitting the Ramjet Pieces

I didn't use the PDF pattern to cut the ramjet tube. I just guessed the angle, drew a line and cut off a wedge. The angle was smoothed with a sanding block.

Down the length of the the tube, a 3/4" width strip was cut out using the aluminum angle.
The inside edge was sanded smooth and flat.

The ramjet half nose cone was taken from my Odd'l Rockets F-104 kit parts.

Wrap some 220 grit around a smaller tube (than it will fit) and sand the concave curve on the underside.
The picture on the right shows a good fit on the BT-50H main tube.
