Ptolemy Class Transport/Tug An end cap disk was turned on a lathe. . .

. . . and test fitted on a kit tube.

The end cap had 6 small holes tapped into the outter perimeter at every 120º. A styrene plate was made with an indented gangway hatch and glued to the center of the end cap.

.08" thick styrene was clamped into an aluminum frame and slowly heated in an oven.

The heated styrene was draped over a kit tube and rolled around it.

The formed styrene was cut into a rectangular shape and sanded smooth. Two small holes were drilled into the pad. These will act as locator holes for the neck part.

Castings of the container cap are made. Small sections of square tubing are cut and glued to the backs of the caps. Putty is applied around the base of the tubing. These squares will act as alignment keys for attaching them to the tube.

Part of the heat formed styrene was cut to a width equalling the space between the pylons on the Polar kit. This shape was cut to a trapazoid and Apoxie putty was packed onto the top of it. While the Polar pylons were held in place, the styrene/putty shape was mashed onto the final kit part location. When removed and dried, the excess putty was trimmed away and sanded smooth. One of the neck castings were then rough cut to shape and held in place.

The pylons were set into place and additional putty was applied to adjust the final fit.

The neck was aligned and glued.

The pylons were snapped into the completed neck part and the tow pad was then snapped on. This assembly was fit onto the saucer.
