Apogee Payload Altitude Rocket Build, Part 2, Tube Cutting & Kevlar Tie

The tubes are almost completely pre-cut by a laser. Cut through the hold down ticks and separate the 18mm lower tube into three parts.

The upper shortest part is the nose cone shoulder. The middle section is the payload sleeve, the longest tube section is the lower rocket body.

After the tube sections are separated, sand the hold down ticks and body tube ends with a sanding block.







The braided Kevlar will unravel some.
To make the bulkhead tie easier, lay some glue on the end to stiffen it up. After it dries you'll be able to make the tie easily.

The red coupler joins the lower body and payload sections.

Tie the shock cord through the smaller outside holes in the bulkhead.
