The closed seat has been developed for the precision sharpening of turning skew chisels with
an oval or square section and with curved or straight edges. Since the chisel is mounted in
the centre of the seat, the bevels are ground to exactly the same shape. The turning skew
chisel is mounted with a side screw (4). Tool size 13 mm (½") to 35 mm (1
⅜
"). It is also suit-
able for carving skew chisels longer than approx 110 mm (4¾").
The open seat, where the tool is fixed with a top screw (5), is used for tools which have the
edge ground square across the shank, such as parting tools, roughing gouges and wide carv-
ing gouges. Both seats are mounted with a bottom screw (6), which also locks the chosen
skew angle. A scale on each seat shows the skew angle.
The closed seat (2) is for skew
chisels. The tool is fixed with
the side screw (4). The top
screw (5) is not used.
The open seat is designed for tools which have the edge square
across the shank. The tool is fixed with the top screw in the hous-
ing (5). As the seat can be turned, it can also be used for short
skew chisels.
Grinding Direction
Grinding away from the edge with Universal Support placed horizontally is recommended.
This gives you following advantages:
• With the lighter grinding pressure you can more easily control the operation.
Especially advantageous when grinding small tools.
• As no water flows over the edge, it is easier to see where the grinding takes place.
• The rotation of the wheel pulls the jig towards the Universal Support.
• No risk of vibration.
