Refer back to the Complete Kit and Individual Components pages to ensure that all necessary parts are located before starting assembly steps.
These tools are required for the assembly of the GreyT Turret (11in ID).
7/16” Wrench
SAE/Inch Allen Set
The following covers the basic assembly instructions for the GreyT Turret (11” ID).
Blue Loctite (McMaster P/N 1004A12) is recommended on all bolts that thread into a tapped hole.

Install the 1/4” ID x 3/4” OD Radial Bearings and 0.03” thick Steel Washers as shown in the image below. They will be installed on all eight bearing stack ups marked in green in the image below.
Install the Turret Gear (140T) sections as shown in the image below. The c-bores on the gear sections should slot together making the gear a single, flat 1/8” thick plate when bolted down.
Once the gear sections are fully seated, tighten the nuts until there is no wiggle in the bolts.
Make sure not to overtighten the 1/4”-20 Nuts as this may cause the bearings to clamp the Turret Ring plate, creating unnecessary friction in the assembly.
Slide the 10T Steel Spur Gear and Clamping Shaft Collar onto the VersaPlanetary with Falcon 500. Then bolt the VersaPlanetary to the assembly from Step 6 using the 3/8” OD x 1-1/4”L Spacers and #10-32 x 1-3/4”L Bolts.
Slide the Clamping Shaft collar and 10T Steel Spur Gear up until the spur gear is resting against the ThunderHex bearing installed in Step 2. Tighten the Clamping Shaft Collar to keep the gear in place.
The 10T Steel Spur Gear must mesh with the gear sections installed in Step 6.
If you did not do so previously, bolt the Turret to the mounting tubes or other support structure you will be using.

Bolt the GreyT Turret Ring and the GreyT Base plates together. The plates can be bolted to whatever tubes the turret is mounted to, if desired.
The Turret Ring plate has a smaller turret hole then the Turret Base. Make sure that the turret is assembled with the plates oriented correctly.
Press the 1/2” ThunderHex ID x 1-1/8” OD Flanged Bearing in to the assembly from Step 1. For this turret, the bearing must be pressed in from the bottom of the assembly.
If you plan on using the turret with a compatible thin section 12.5” OD bearing (SA120XPO), the Turret Base and Ring plates will have to be tapped together. This will allow you to use #10-32 x 3/8”L Bolts (WCP-0252) to constrain the thin section bearing.
Slide the 1/4”-20 x 1-1/4”L Bolts through the holes marked in green below. Slide all components on to the bolt as shown in the image below. Make sure there is one 0.03” thick Steel Washer between the plate and each 1/4” ID x 3/4” OD Radial Bearing.
Repeat this step for the remaining seven bearing bolt holes.
While assembling the parts in this step, use a piece of tape to hold the head of the bolt in place so that the bolt does not fall out. This will also help in future steps.
Failure to install the washers will greatly increase the friction in the system and may result in the turret not being able to rotate.
Rest the assembly from Step 2 on top of the 1/4” ID x 3/4” OD Radial Bearings installed in Step 3. This step is assembled upside down, meaning that the Turret Ring plate will be the plate that rests on the 1/4” ID x 3/4” OD Radial Bearings.
