Apogee Payload Altitude Rocket Build, Part 4, Nose Cone Sleeve, Smoothing The Edges

The short section of BT-20 is glued into the thin vacu-form plastic nose cone with some medium super glue.

The fit seemed loose so I added some white glue to to the shoulder to increase the outside diameter.





Here's the slip fit of the nose cone into the upper payload tube.

The nose cone is held in place with a wrap of thin tape for flight.

This is the back end of the low body section.

You can see the laser cut fin gluing lines. The cross line towards the bottom is the placement of the trailing edge of the fin.

The engine is also held in place with a wrap of tape. An engine block is provided but won't be used to keep the weight down.

With the back end getting a wrap of tape, I like to add a wipe of CA glue to strengthen the tube. The inside of the tube also got some CA applied with a Q-tip.

There is a tube edge "step" where the payload section joins the coupler sleeve. To smooth it out, CA was applied to the edge and smooth sanding with 400 grit.
