01. Frame Assembly

The following tools are required for this section of the guide:

Allen key / hex wrenches in the following sizes: 4mm & 5mm

Avoid using ball end hex wrenches on the Quick Connectors as they are more prone to damaging the heads of the Set Screws

Spanners / wrenches in the following size: 13mm

A pair of scissors

The following tools are recommended for this guide:

A tape measure

An Engineer Square

The following steps show how the aluminium extrusion Quick Connectors are prepared and installed. The V-Core 4.0 frame assembly begins on step 7

The Quick Connectors are supplied in two parts:

Quick Connector T-Nut Pin with the O-Ring pre-installed

Quick Connector Housing with the Set Screw pre-installed

Before trying to install a Quick Connector Housing into an extrusion, check that the Set Screw is not blocking the hole in the Quick Connector Housing

If the Set Screw is blocking the hole in the Quick Connector Housing, slightly unscrew it to achieve the necessary clearance

Example extrusion

Quick Connector Housing

Insert the Quick Connector Housing into the hole in the aluminium extrusion

Please note: If the Quick Connector Housing is difficult to insert into the aluminium extrusion, try inserting it from the opposite side

Make sure that the Quick Connector Housings all face the same direction

Make sure that the hole in the Quick Connector Housing is aligned with the central hole on the aluminium extrusion as shown

Insert the Quick Connector T-Nut Pin into the central hole on the extrusion slot

Make sure the "notch" in the pin is facing towards the Set Screw

Quick Connector Set Screw

Using a 4mm hex key, tighten the Set Screw just enough to hold the Quick Connector T-Nut Pin inside the extrusion

If correctly tightened, the Quick Connector T-Nut Pin should still move slightly backwards and forwards, but should not come loose

Slide the second aluminium extrusion into position, aligning the Quick Connector T-Nut Pin into the slot of the second aluminium extrusion

Be careful not to scratch the aluminium extrusions when assembling them

Quick Connector Housing Set Screw

Fully tighten the Set Screw to secure the extrusions together

The Set Screw will cause the Quick Connector T-Nut Pin to pull tight against the second extrusion, securing them together

If the extrusion connection is loose after fully tightening the Set Screw, loosen the Set Screw and check that the Quick Connector T-Nut Pin was properly positioned. The connection will not tighten if the "notch" on the pin is not aligned with the Set Screw

Set Screw

Quick Connector Housing

Quick Connector T-Nut Pin

The Set Screw within the Quick Connector Housing engages with the "notch" in the Quick Connector T-Nut Pin

As the Set Screw is fastened, the T-Nut Pin is pulled inwards, causing the extrusions to lock together

All of the extrusions for the V-Core 4.0 are provided packed in the same box. The SKU varies depending on the size being assembled:

V-Core 4.0 - 300: Rat Rig V-Core 4.0 - CNC Milled Profile Pack v1.0 - 300 (SKU: HW3984MK)

V-Core 4.0 - 400: Rat Rig V-Core 4.0 - CNC Milled Profile Pack v1.0 - 400 (SKU: HW3985MK)

V-Core 4.0 - 500: Rat Rig V-Core 4.0 - CNC Milled Profile Pack v1.0 - 500 (SKU: HW3986MK)

Be careful when opening the package. Do not use a long blade to cut the box open as you can damage the extrusions

Unpack each layer carefully, placing the extrusions to the side for now

There are four layers of extrusions to unpack

The 2020 V-Slot extrusion will be used in a later guide. All others are used in the construction of the frame
