Purchasing the GreyT Shooter (9.5") has been simplified to buying a "Complete Kit" or "Individual Components".

The "Complete Kits" will have all the necessary parts to assemble the Shooter minus motors and the Limelight.

"Individual Components" is an option for teams if:

• They already have some of the parts on hand, such as gears, bearings, or raw material

• Want to purchase spare parts

• Upgrading from one version to another version

Assembly Prep

Refer back to the Complete Kit and Individual Components pages to ensure that all necessary parts are located before starting assembly steps.

Tools Required For Assembly

These tools are required for the assembly of the GreyT Shooter (9.5")

• 3/8” Wrench

• SAE/Inch Allen Set

• Drill and Drill Bit Set

Key Assembly Instructions

The following instructions detail how to assemble the basic frame for the GreyT Shooter (9.5”).

Base Assemblies

Drive Assemblies

Shaft Cut Guide

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. However, cutting to length and then using a lathe to clean up both ends is the recommended method.

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. This is so the clamping collar can properly compress the shaft.

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 7.5”, 8”, 8.5”, 9”, and 9.5” distances from a 4” wheel to the hood.

The holes have a 10 degree spacing, with the maximum angle being 70 degrees. The holes marked in green in the image below are for the wheel guard. They protect the wheel, provide the shooter with extra support, and provide the limelight with a spot to mount.

Direct Drive Guide

The image below shows a section view of a shaft being direct driven by a Falcon 500. The Falcon output shaft is outlined in green. The hole for the shaft must be drilled deep enough for the falcon shaft. The split must be cut from one corner of the hex to the opposite one. This allows the shaft collar to clamp the shaft around the Falcon spline.

The following details the assembly instructions for the Limelight. The Limelight provides the shooter with vision tracking, and can be used in tandem with the GreyT Turret (11” ID) to greatly increase the accuracy of the overall system.

Step 1

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 2

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

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.

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.

The following details the assembly instructions for the Direct Drive configuration. This configuration provides the shooter with a 1:1 ratio from the Falcon 500 motor.

Step 1

Install the Falcon 500 using #10-32 x 3/8”L Bolts.

Step 2

Install the components in the order shown in the image below. They will be concentric with the bearing hole marked in green in the image below.

Slide the 1/2” ThunderHex Shaft on to the Falcon 500 output shaft. Then slide the 1/2” Hex Clamping Collar over the Falcon shaft and tighten it down.

For more information regarding direct driving a shaft using a Falcon 500, see the page with the Direct Drive Guide.

GreyT Shooter (9.5") (WCP-0499)

Hardware

The GreyT Shooter (9.5”) is the next iteration of the GreyT Shooter. Originally designed for the 2020 FRC Game: Infinite Recharge, the GreyT Shooter is perfect for the most recent FRC Game: Rapid React when sized up appropriately. The new GreyT Shooter accepts 7.5”, 8”, 8.5”, 9”, and 9.5” distances from a 4” wheel to the hood.

Notable Features

• Easy adjustability of compression

• Compatible with Falcon 500, VersaPlanetaries

• Option for Direct Drive, Belt Drive, or Gear Drive

• Gear Drive option allows teams to really fine tune RPM during testing

• Compatible with GreyT Turret

• New Top Roller plate allows teams to alter the spin of the game piece and shoot further

Common Questions

Q: What wheels are recommended?

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

Q: What size game objects does the shooter support?

A: This GreyT Shooter was designed with a 9.5” 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:

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

2. 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.

3. If both of the previous suggestions do not work, then you may have to either gear the shooter faster, or add the top roller.

Product Updates

The following instructions detail how to assemble the basic frame for the GreyT Shooter (9.5”).

Step 1

Press the 1/2” ThunderHex ID x 1-1/8” OD Flanged bearing into the Shooter Side Plates. The bearing will be installed from the opposite side for the other Shooter Side Plate.

Step 2

It is recommended not to skip any standoffs between the first and last holes used on the plate.

Bolt all four standoffs into the holes for the wheel guard at the front of the shooter.

Step 3

Use the remaining #10-32 x 2-1/4”L Bolts and 3/8” OD x 1-3/4”L Spacers to attach the other Shooter Side Plate.

Step 4

Cut a piece of 1/16” Polycarbonate Plastic for the backing of the shooter hood. It is recommended to cut this piece of plastic roughly 1” longer so you can wrap the plastic underneath the lowest 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 your way up. Drill one set of holes and then secure with the zip tie before moving on to the next standoff.

Step 5

Install the Aluminum Nutstrips to the bottom of the shooter. The Nutstrip that comes with the shooter can be cut into four 1-1/2” long pieces for the shooter. These pieces can be installed with #10-32 x 1/2”L Bolts.

The following details the assembly instructions for the Belt Drive configuration. This configuration provides the shooter with a 1:1 ratio from the Falcon 500 motor.

Step 1

Slide the components on to the Falcon Spline to 1/2” Hex Adapter in the order shown in the image below. Use the two 1/2” Snaprings to secure the Pulley and Spacers on the Falcon Spline to 1/2” Hex Adapter.

Step 2

Install the components in the order shown in the image below. They will be cocentric with the bearing hole marked in green in the image below. The 70T GT2 Belt must be installed during this step.

Constrain the 1/2” ThunderHex Shaft with two 1/2” Hex Clamping Collars. The Collars should be flat with the ThunderHex Bearing flanges.

Step 3

Install the Falcon 500 using #10-32 x 3/8”L Bolts. The Solid Roller Wheels can be shifted to the other side of the Shooter to help with this step. When the motor is installed, slide the Solid Roller Wheels back to the center of the shooter. Use the 1/2” Hex Clamping Collars to constrain the wheels.
