Top Roller

The following details the assembly instructions for the Top Roller. This assembly can help control the spin of the game object, and can even help the shooter launch the object further than with just one roller.

Blue Loctite (McMaster P/N 1004A12) is recommended on all bolts that thread into a tapped hole.

Step 1

Press the 1/2” ThunderHex ID x 1-1/8” OD Flanged Bearing into the Roller Center Plate. Bolt the Roller Center Plate to the Top Roller Plate using two #10-32 x 1/2”L Bolts.

The other Top Roller Plate will be left open, since that is where the Falcon 500 motor will mount.

Step 2

Slide all the components on to the 1/2” ThunderHex Shaft in the order shown in the image below.

Two of the 1/2” Hex Clamping Collars will be used to constrain the Solid Roller Wheels in the center of the shooter, and the third one will be used to tighten the shaft around the falcon output shaft. Leave that third one loose.

Step 3

The components will be installed in the order shown in the image below. The Top Roller will be direct driven. For more information regarding direct driving a hex shaft with a falcon, see the page labeled Direct Drive Guide.

Once both Top Roller Plates are bolted in the correct position and the shaft is installed, slide the Solid Roller Wheels over to the center of the shooter. Use the two 1/2” Hex Clamping Collars to constrain the wheels.
