Installing the 20mm Little Ball on 1 Inch Tube

Installing one or more 20mm "Little Ball for 1" Tube" onto a Vector Bar or other 1" tubing is straight forward. It will require some simple tools, some patience and a little time.

Follow these steps to install your JK Mount™ base. Allow 10-20 minutes.

Step 1 - Remove the Vector Bar

For optimal control of the drilling and tapping during installation, remove the Vector Bar from the dash so you can drill and tap carefully at a workbench in your garage, or shop. Use the instructions that came with the Vector Bar for guidance.  

Step 2 - Gather the items you need

It only takes a few simple tools to complete the installation of the Little Ball. This process requires only drilling one side of the tube and tapping a 6mm thread for the included fastener.




For this process, you will need the following items:

  • 1 x Vector Bar
  • 1 x 6mm tap
  • 1 x 5mm drill
  • 1 x Sharpie
  • 1 x Little Ball for 1" Tube (and included 6mm socket fastener)
  • 1 x 5mm socket wrench
  • 1 x Punch and hammer
  • 1 x Electric drill.
  • 1 x Eye protection/safety glasses

You may also wish to use:

  • Some blue or masking tape to protect the coating of the 1" tubing. (Photos show an a Vector Bar before coating)
  • 1 x 3mm drill to use for a pilot hole
  • 1 x a smidge of Loctite Red 277 thread-locker 

Step 3 - Mark the position of the hole to be drilled and tapped

 Mark the drill point

Using your best judgement based on the way you are supporting the Vector Bar, with the Sharpie mark the desired location. 

Optional: Use blue or masking tape over the coating for better contrast.

Step 4 - Using a punch and hammer for a clean start to the hole (recommended)



This is an optional step, but we do recommend using a punch to prevent drill bits wandering off the top of the tube in the area you marked. 

A good clean blow should be sufficient to create the indentation for the drill bit.


Step 5 - Pilot Hole (optional) 

Pilot hole

 This is an optional step of using a 3mm drill bit for a pilot hole. This can make drilling with the required 5mm drill bit easier and more accurate on the tube.


Step 6 - Drill the 5mm hole 


Carefully drill the 5mm hole required for the 6mm thread tap.

Be sure to wear safety glasses and be mindful of swarf.


Step 7 - Create the thread using a 6mm tap 

6mm tap

Creating a thread in the tube wall is very easy, but care and attention is required. Follow these steps:

  1. Gently position the tapered 6mm tap into the 5mm hole.
  2. Check for an accurate alignment and with both hands on the tap holder, gently turn until you feel the tap 'biting' the metal. Be gentle and do not go too heavy.
  3. When you feel the tap start to 'settle' and cut the thread, stop and back up a 3rd of a turn slowly.
  4. Now begin to rotate clockwise again and feel the tap bite in again. Mybe 1/3rd to 1/2 a turn. Back up 1/3rd of a turn to break the cut metal.
  5. Repeat step 4 until the tap is rotating cleanly without binding. At that stage the 6mm thread is ready.
  6. Very gently back out the tool being very careful to not accidentally create a cross thread as the tool tapers and comes out.
  7. Set the tap to one side. Avoid re-entering the hole as that can cause you to create a cross thread and the fastener will not hold.

Step 8 - Test fit the 6mm fastener included with the Little Ball for 1" Tube


It's always a good idea to test fit to make sure the 6mm thread is clean. This should work smoothly with fingers only.


Step 9 - Finish by installing the Little Ball with the 6mm fastener


Installing the Little Ball for 1" Tube is very straightforward. We do recommend the use of a strong thread-locker like Loctite Red 277, if available, to help prevent the 6mm fastener backing out over time.  


Summary - The Little Ball for 1" Tube and the Clamp

Comparing the options

The Little Ball for 1" Tube has advantages compared to the alternative Vector Bar/Handle Bar clamp. 


  • Smaller overall footprint when you know you want fixed positions
  • Lowest profile of any 20mm base
  • Curved base to prevent rotation
  • Quick installation
