# Internal String

{% hint style="success" %}
Vibra-TITE VC-3 Threadmate ([Vibra-TITE](https://wcproducts.com/products/threadlocker)) is recommended on all bolts that thread into a tapped hole.
{% endhint %}

## Mounting Pattern

This hole pattern is for the standard mounting style of the Non-Flipped GreyT Telescopes. The table below shows the dimensions that change between the different base tube sizes. Unless otherwise specified, all other dimensions are the same across all Non-Flipped GreyT Telescopes.

| **Base Tube Size** | **Dimension A** |
| ------------------ | --------------- |
| 1-1/2"             | 1"              |
| 2"                 | 1-1/2"          |
| 2-1/2"             | 2"              |
| 3"                 | 2-1/2"          |

## Mounting Example

The hole patterns for the individual nutstrips will line up with the scores on the VersaFrame Tube. The distance between the holes will be the same as indicated in the previous section labeled Mounting Pattern. Drill the holes using a #9 drill bit.

Bolt the Non-Flipped GreyT Telescope to the two tubes using four #10-32 x 1-1/2"L bolts.

{% hint style="info" %}
The installation of the nutstrips is discussed in Step 3 of the Gearbox Assembly Instructions.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wcproducts.com/welcome/greyt/greyt-telescope/applications/mounting/internal-string.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
