Dan Kubin Needle Bar Tensioner

The most significant update to the V3/24 Sidewinder is the added (and optional) Needle Bar Tensioner. This added Tensioner eliminates the need to use a Rubber Band, improving all around machine performance and results. Tensioner reduces spitting and increases power. 

The V3/24 Tensioner can be used on all versions of Dan Kubin V3Rs, 2019 to 2024. 

Needle Bar Tensioner Specifications:

• Lightweight Aerospace Aluminum Arm with precision made custom bearing
• Creates necessary needle bar tension for stability, eliminating the need to use a Rubber Band
• Moves forward and backwards, in and out of position easily by loosening and tightening the thumbscrew
• When setting up your needle and tube, position Needle Tensioner in desired position depending on the amount of tension you want to add to the needle bar. 
• Adjust position by loosening the thumbscrew, pull arm back and then tighten when you reach desired tension. 

Upgrade Step by Step: 

1. Loosen and remove the thumbscrew
2. Insert thumbscrew into hole in Needle Bar Tensioner
3. Re-insert thumbscrew into frame with Tensioner bearing facing inwards (see picture)
4. Ensure Vise Slide is in correct position, so the thumbscrew easily threads into Slide
5. Tighten with Needle Bar Tensioner in desired position

**OG V3R and V3/23 SPECIAL NOTE - Use of this Tensioner instead of Rubber Bands will noticeably increase the strength of your machine. If it is hitting too hard using the Needle Bar Tensioner, simply adjust your voltage and turn the machine down and adjust stroke wheel setting as needed to accomplish desired speed / hit.
