A correction to the list, it's not connector, rather converter.
Also, the Rocket Doctor has written and reviewed many instructions, including those of the Interceptor (unless they have been edited).

The original Deluxe Super Shot Screw Machine was originally in Wal-Mart as a starter set, then, discontinued, now, it's a bagged kit and is now called the Converter.

There were four more designs scheduled to be produced, but, dropped, when the Forum was dropped.

These were going to be the "good things to come" as the RD stated !!!!
