With the Tormek EzyLock, which is both a nut and a washer, you need no tools for mounting and dismounting the stone. The special pitch on the left hand thread causes the rotation of the wheel to tighten the nut to the right torque.
When mounting the grindstone, turn by hand the Ezylock nut anticlockwise into position. It will automatically tighten to the right torque during the first sharpening.
If you need to change stone, turn the stone clockwise while fixating the leather honing wheel with the other hand and the EzyLock will easily loosen.
This construction makes it easy to work with different grindstones, from the Tormek Original Grindstone to the specialty stones Blackstone Silicon for High Speed Steel and the 4000 Grit Japanese Waterstone.
Holes for the drive pin
New drive wheels
New drive wheels have a deep groove for the drive pin. Use pre-drilled hole.
Older drive wheels
Older drive wheels have a shallower groove (5 mm or 3/16″) for the drive pin. You can either buy a new drive wheel (Art. No: R23) or drill a ∅ 4 mm hole. See the instruction for more information.
