Aerotech Mantis Launch Pad, Part 4, Rod Adapter Disk & Support Arms

Here's the two sides of the Adapter Disk.

Notice the round slots for a 1/8", 3/16" and 1/4" launch rods.

There are two pins. With the pins aligned, all launch rod slots will correctly align.

Do not glue the Adapter Disks together.

Here's the outside surface of the disk assembly, slid into the top of one side of the Swing Arm.

Align the 1/4" hole with the round slot running through the top of the swing arm. 

The two sides of the Swing Arms are screwed together using the two 1 75" long bolts, small washers and wing nuts.

Slide the large Support Arms into the side flange  of the Swivel Head. The instructions say to use some plastic cement on the bottom of the Support Arm.

The Arms are screwed into the Swivel Head using the two 1/2" long Screws.
