Do you find that using your plane's adjusting knob is a bit difficult? Well we did and decided to fix that by creating our Plane AdjuSTAR 2.0 adjusting knob to replace the original adjusting knob on most WoodRiver & Luban bench planes.

Our Plane AdjuSTAR 2.0 is larger and much easier to use than the original adjusting knob allowing you to make adjustments to your blade depth setting easily.  Our design makes it easier for you to reach and turn the adjuster with your fingers and easier for you to reach the frog adjustment screw with a screwdriver. We know you will love our Plane AdjuSTAR 2.0.


  • Made of forged brass.
  • Designed to fit WoodRiver and Luban brand bench planes numbers 4-1/2, 5, 5-1/2, 6, 7, and 8.  Requires removal of handle to install (see installation video).
  • WIll Not Fit the WoodRiver or Luban bench planes number 1, 3, 4 and 62. 
  • Diameter: 1-7/8 inch outside diameter.

Adjustar for Quangsheng (Luban) No. 5 1/2

Brilliant innovation. Easy to fit. Works a treat. Only (very minor nit-picking) criticism/improvement: if you could slightly reduce the clearance on the fitting where the yoke drops into the flange to reduce play on the adjustment by a few thousandths it would be even better.

All Planes Should Come With These!

Added this to my new WR 5 1/2 jack plane. Big improvement in usability. Easy and precise depth adjustments with a flick of your finger.

At $45, it is not cheap, but if you use your plane a lot, you will be very glad to have it.

This has got to be the best “fix” since sliced bread. I have minor arthritis, making my 6-1:2” Wood River bench plane adjuster virtually impossible to turn without putting it down, adjusting and putting it back to work. This Adjustar was easy to install and it works flawlessly. It’s also machined beautifully. I couldn’t be more pleased.

Adjustar for Woodriver 5 &1/2 Jack

An excellent product! Woodriver should have made this part of the original design!.

Adjuster 2 Great upgrade

I recently purchased the adjuster 2 for my wood river 5 1/2, and I love it. I will be getting another one for my 4 1/2 and my jointer wood river planes. Rob Cosman sells a wonderful product and I will be getting all my dove tail supplies from him as well.
