The Woodpeckers router plane has blades which are removable from the blade holder shaft. These blades can then be sharpened on the Tormek grinder using a blade holder sharpening jig held in the Tormek SE-77 Square Edge jig or SE-76 Square Edge Jig.

Pictures of this approach are to the right. The blade holder sharpening jig is shown as the red part.

These blade holder sharpening jigs are designed for quick setup of the Tormek using the Tormek TTS-100 Turning Tool Setter. That means the process is fast, and the craftsman can get back to work sooner. (The sharpening workflow is outlined below.)

There are two versions of the blade holder sharpening jigs:

1. one for the straight blade, and
2. one for the spear point blade.

The two blade holder sharpening jigs are designed to be 3D-printed, and the designs are provided below.

You can click on any of the pictures to see a larger version.

Notes:

1. SE-77 Jig: The Alignment Jig for the SE-77 may be helpful to ensure this jig works as expected, especially for the straight blade.
2. SE-76 Jig: The alignment jig is not needed if you are using the SE-76 Square Edge Jig as there is no camber adjustment on the SE-76.
3. SVH-60 Jig: The SVH-60 Straight Edge Jig can also be used; however it will need to be setup differently. The dimensions on this jig are different from the SE-77 or SE-76, so the TTS-100 cannot be used for setting up the universal support bar (USB).

   The alignment of the blade holder sharpening jig to the SVH-60 jig is the same however.

Usage Notes

The blades supplied by Woodpeckers should only need to be honed periodically. If re-sharpening is required, then this tool holder should work, but the grinding should not be aggressive.

The sharpening workflow steps are:

1. Set the Tormek’s Universal Support Bar (USB) using the B setting on the Tormek TTS-100 jig.

   The horizontal, edge-trailing position is necessary for use on honing wheels, and is recommended when using the Japanese waterstone (SJ).

2. Remove the blade from the Woodpeckers router plane’s blade holder shaft.
3. Attach the blade to the blade holder sharpening jig (the red part). Be sure to use the appropriate jig for the blade you are sharpening.
4. Insert the blade holder sharpening jig into SE-77 jig.
   1. The blade should be on the bottom, towards the grindstone. That is the position shown in the pictures to the right.
   2. Ensure the registration face is flush against the bottom bar on the SE-77 jig. The pictures at the top of this page show that placement.

      Do note that the spear point blade holder has two registration faces: one for each side of the blade’s edge. You will need to hone one side, and then reposition the blade holder sharpening jig for the other side and hone it.

5. Use particular care when polishing the back side of the blade to remove the burr. This side was polished at the factory, and you do not want to alter the blade’s geometry.
6. Once the blade is honed, remove it from the blade holder sharpening jig, and then it can be re-attached to the Woodpeckers router plane’s blade holder shaft.

Notes on Making an Alternate Design

An alternate design was created which does not require the SE-77. This design works well for the straight blade; however adapting it to the spear point blade will require a bit more effort.
