Step 5

Cut a piece of 1/16” polycarbonate for the backing of the shooter hood. It is recommended to cut the piece slightly longer, about 1”, so that this extra length can be wrapped under the first standoff. This prevents the game object from being caught on the plastic as it feeds through the shooter.

Zip ties are the recommended means of attaching the plastic backing. Start from the first standoff and work up. Drill one set of holes and then secure with the zip tie before moving on to the next standoff.

Step 6

Attach 1” x 1” VersaFrame Aluminum Angle to either side of the shooter with bolts or rivets.

Step 7

Center the Limelight Mount between the Shooter Side Plates. Secure the Limelight Mount to the two top most standoffs using four #10-32 x 1”L bolts and nuts.

Step 8

Attach the Limelight to the Limelight mount using four #10-32 x 2”L bolts and nuts.

The following instructions detail how to assemble the 775pro Belt Drive configuration.

Step 1

Slide ThunderHex through bearing on one side of shooter assembly. Install remaining components as the shaft is slid through to the other side.

Step 2

Press the 12t pinion onto the 775pro motor before installation.

The 775pro aligns with the hole further from the bearing hole.

Use two M4 bolts to secure motor. Install motor on opposite side as well.

Center the solid roller wheels and tighten all shaft collars.

Step 3

Install the Hex Bore Mag Encoder Housing on the ThunderHex shaft and secure with a 1/2” hex collar.

The following instructions detail how to assemble the 775pro VersaPlanetary Drive configuration.

Step 1

Install VersaPlanetary with the desired gear ratio using two #10-32 x 1/2”L bolts.

Install motor and gearbox on the opposite side as well.

Step 2

Slide the hex couplers onto the VersaPlanetary Output shafts before installing the ThunderHex shaft.

Install ThunderHex shaft and solid roller wheel. Center the solid roller wheel and tighten the shaft couplers.

Assembly Prep

Tools Required For Assembly

These tools are required for the assembly of the GreyT Shooter (7").

• SAE/Inch Allen Set

• 3/8” Hex Wrench

• Drill w/ Drill Bit Set

Key Assembly Instructions

The following pages cover the basic assembly instructions for the GreyT Shooter (7").

Shooter Side Plate Guide

The GreyT Shooter is designed to support multiple object sizes and multiple compression values for a certain diameter. The side plates have hole patterns for 5”, 6”, and 7” distances from a 4” wheel to the hood.

The GreyT Shooter also supports various motor and motor mounting options.

Hex Shaft Cut Lengths

The overall length for the hex shafts does not need to be precise. Cutting to length with a hacksaw is acceptable if that is the only available option. Cutting to length and then using a lathe to clean up both ends is the recommended method though.

When cutting the slit on the Falcon Direct Drive Shaft, the slit needs to be cut from one point of the hex to the point on the opposite side.

The 2020 WCP CC utilized the Greyt shooter for scoring in the outer and inner ports the target in the 2020 FRC game Infinite Recharge. The shooter was used in combination with the Greyt Turret and the Limelight 2+. This combination is simple to use and combine for a robust scoring system. The shooter can also be used as a stand alone assembly.

Common Questions

Q: What wheels are recommended?

A: The WCP Solid Roller Wheels or 4” Flex Wheels are the recommended wheel to use.

Q: What size game objects does the shooter support?

A: This GreyT Shooter was designed with a 7” game object in mind. Other sizes may be used but the performance may vary as smaller or larger game objects were not taken into consideration.

Common Issue

Issue: Not shooting far enough

Possible Solutions:

• The RPM may not be high enough. Try increasing the RPM to gain for distance.

• The compression on the game object is not enough. Try increasing the compression by moving the standoffs that support the plastic hood backing forward to the next set of holes.

Step 1

Press ThunderHex Bearing into the shooter side plate. Repeat this step for the other side. Be sure to press the bearing in from the opposite side so that the bearing flanges are on opposite sides of the plates.

Step 2

Repeat the step for the desired amount of holes to achieve the exit angle wanted.

It is recommended to not skip any holes between the first and last standoff used.

Step 3

Install the spacer and standoffs in the front guard set of holes.

Step 4

Use the remaining spacers and bolts to attach the other side plate.

The following instructions detail how to assemble the Falcon 500 VersaPlanetary Drive configuration.

Step 1

Install VersaPlanetary with the desired gear ratio using two #10-32 x 1/2”L bolts.

Install motor and gearbox on the opposite side as well.

Step 2

Slide the hex couplers onto the VersaPlanetary Output shafts before installing the ThunderHex shaft.

Install ThunderHex shaft and solid roller wheel. Center the solid roller wheel and tighten the shaft couplers.
