Square Edge Jig SE-77 (SE-76)
SE-77 is a further development of SE-76. The jig now has an adjustable side.
Positioning of Machine
Design
See illustration on the next page. The jig comprises an upper base with a lower clamp
and two locking knobs for fixing the tool. The jig slides on the Universal Support on nylon
bushings across the grinding wheel. The edge angle is set with the Micro Adjust (3) on the
Universal Support (4).
There are two safety stops to prevent the tool from slipping off the wheel when grinding.
One inner stop (1) to be positioned according to the width of the tool and one outer stop (2)
mounted on the end of the Universal Support.
The jig lines up the chisel to its upper flat side, making it easier to mount it correctly (not
twisted). Conventional jigs need manual alignment.
The lower clamp has a ridge in the centre enabling shorter tools with a tapered shank to be
firmly mounted, e.g. Japanese chisels. The upper base, which lines up the tool, is designed
so the clamping pressure is distributed to the ends and the tool mounts firmly without a
heavy tightening of the knobs.

- Page 4 The height of the Universal Support determines the edge angle. This can be set in two ways. Either you can exactly replicate the existing angle using the Marker Method or you set to a new angle according to your choice using the Tormek AngleMaster WM‑200. Sharpening an existing edge angle Colour the bevel with a marker.

- Page 7 Finer Surface with the Stone Grader You can refine the tool surface by grading the Tormek Original Grindstone with the fine side of the Tormek Stone Grader SP‑650. Pressing the Stone Grader firmly towards the grind‑ stone refines the grindstone surface so it acts like a 1000 grit stone. If you are replicating an established edge angle, you can go directly to this finer surface of the stone.
- Page 8 Since the grinding and honing of the entire bevel with the Tormek method is an easy and fast operation, there is no need for a secondary bevel. With a single bevel, you can set exactly the angle that you want and easily maintain it at every grinding and honing.
