# Multi-Stack Assembly

## Step 1

Align the pin on the Single slice with the matching pocket on the Double slice. Install the desired amount of #2-28 screws to hold the pulley slices together. Be sure to tighten the screws fully. There should be no gap between the pulleys when they are assembled.

A piece of 1/2" OD Hex can be used to line up the parts during assembly.
{% endhint %}

## Step 2

Repeat the process from the previous step with a Double slice. This process can be repeated for as many Double slices as desired.

{% hint style="info" %}
For multi stack assemblies, the screws will all be facing the same direction if screws are used. Screws can be omitted if the slices are constrained by collars or snap rings.
{% endhint %}

## Step 3

After adding as many Double slices as desired, add the final Single slice to the outside. Install the final set of screws, if screws are to be used.

{% hint style="info" %}
For multi stack assemblies, the screws will all be facing the same direction if screws are used. Screws are not included and can be omitted if the slices are constrained by collars or snap rings.
{% endhint %}
