Overview

Projection Jig for the TTS-100

I made these pieces using my 3D printer to make it easy for quick-and-dirty resharpening of my chisels when using the Tormek SE-77 jig. The concept is that the distance from the USB to the grindstone is set using the B hole in the Tormek TTS-100, and the tool projection is set using this jig.

Settings for projection when using the SVD-186 are also available so that this can be used for both jigs.

Special thanks are due to Jan H (jvh on the Tormek Forum, and developer of TormekCalc²) for calculating the projections necessary for the SE-77 using parametric CAD.

Usage Notes

Using the SE-77 Jig

The steps for using this jig to sharpen a tool are:

1. Set the distance between the USB and the grindstone using the TTS-100 Turning Tool Setter. The B setting gets used.
2. Set the skew on the SE-77 at the desired angle. If you want it to be a straight grind, the Alignment Jig for the SE-77 may be useful.
3. Set the tool’s projection from the SE-77 using the desired angle. The three pre-defined angles are on the left side of this jig.
4. Sharpen the tool as needed. If you remove more than a small bit of the tool (e.g., from squaring up the end of a chisel), you may need to repeat step 3 and re-set the tool’s projection.

The video referenced below, Jigs for the Tormek SE-77, shows the steps for this jig is used.

Using the SVD-18x Jig

For the SVD-18x* jig, the right side of this jig has the same projection distances as the TTS-100. It is repeated here for convenience.

The steps for using this jig to sharpen a tool are outlined below. The jig setting and projection are based on your desired grind, and are outlined in the user manual for your SVD-18x jig.

1. Set the distance between the USB and the grindstone using the TTS-100 Turning Tool Setter. Either the A or the B setting gets used, depending on desired grind.
2. Set the SVD-18x’s jig setting at the desired value.
3. Set the tool’s projection from the SVD-18x using one of the values on the right side of this jig.
4. Sharpen the tool as needed. If you remove more than a small bit of the tool, you may need to repeat step 3 and re-set the tool’s projection.

Sources for Buying One

You can purchase one from Colvin Tools.

Notes on Making One

This file is available for printing as a single piece or two.

Two-Piece Design

The jig I originally made is two pieces as that is easier to 3-D print on my older, Creality Ender 3 printer.

One-Piece Design

If you would prefer to print a single file, this one is available. It also includes the text as objects so multiple filament printers can print the text as a different color.

The Fusion 360 file (f3d) is also supplied in case you would like to modify this design for different uses.

• Jigs for the Tormek SE-77 (YouTube video). This video covers two jigs which I 3D print which make using the SE-77 easier. The first jig is this one. The second jig is the Alignment Jig for the SE-77, and is used to ensure the alignment screws on the SE-77 are set correctly to ensure the chisel does not have a skewed edge.

  This video also reviews how to use this jig.
