Lawn Dart Rocketry SLAT/S Build, Part 8, Parts Fitting

The fin fairing pieces had the balsa grain filled with CWF and sanded smooth.
I wanted to shoot the pieces with filler/primer before gluing the fins in the slots.

A strip of masking tape was cut a little wider than the slot widths. This was pressed into place, the overhand kept the filler/primer off the sides of the slot.




The Starlight nose cones are now available from Apogee. The shoulder lip is a hair wider than normal, but fits the BT-50H (heavy wall BT-50) tubes perfectly.
Sometimes you find a slight flare at the lip. This was sanded down slightly to fit the body tube diameter even better.

The intake tube was slid over the bottom of the main tube. Lines were drawn along the sides.
The primer was scraped along the line for a better glue bond.

Sandpaper was wrapped around an engine casing and the bottom curve sanded. As I mentioned before, I use a smaller diameter piece to wrap the sandpaper around.





And, here's the fit.
Set against the intake, it didn't go as planned -
