3D-Printed Projection Jig
for the SE-76 or SE-77 with 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-76 or SE-77 jigs. 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.

David Bedrosian of Bedrosian Woodworks designed a variation of this which uses magnets to hold parts in place. It is a really innovative approach.

He sells the jig or plans for the jig, and you can get them by contacting him at his eMail: bedrosianwoodworks at gmail dot com (not a link; just blue to highlight it) or DM him on Instagram @BedrosianWoodworks.

There is link to his YouTube video below which shows how he uses this jig.

Usage Notes

Using the SE-76 or 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. If using the SE-77 jig, set the camber 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-76 or SE-77 using the desired angle.
  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.
* SVD-180, SVD-185, SVD-186, or SVD-186-R

Sources for Buying One

You can purchase one of the 3D-printed from Colvin Tools.

You will need to contact David Bedrosian to purchase his (or the plans for making it).

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.

Part 2 - Bottom Hook TTS-100 ProjJig - Part 2.stl

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.
