When the desired shape is achieved, check that the protrusion
has not decreased during the shaping. If so, re-position the
tool to the correct protrusion and then make the final shaping.
By doing so, you will ensure that you exactly replicate the edge
geometry at future sharpenings.
Rounding Off the Heel
Some turners round off the heel of the bevel on bowl gouges and spindle gouges. The jig
is designed so that you can move the tool towards the stone and grind the heel. The heel
can be ground either as a flat secondary bevel or rounded off by sliding the jig back and
forth during grinding. If you want a more pronounced rounding off, you move the Universal
Support a little towards the grindstone.
You can round off the heel by
moving the stop ring (4) and
the sleeve (2) backwards.
Press the jig towards the grind-
stone so that the stop ring (4) is
in touch with the sleeve (2).
Moving the Universal Support
closer towards the grindstone
gives you a more pronounced
rounding off.
Full swing.
Limited swing.
Length of the Wings
The length of the wings depends on how
wide you swing the tool from side to side.
Shape of the Wings
Watch that you grind on the right spots
on the bevel so the wings become sym-
metrical and slightly convex or straight.
They must never be concave.
Convex.
Concave. Not suitable!
Note
You decide how much grinding takes place on any
one spot and hence the final shape. If the wings tend to
be concave, then grind more on the centre of the edge.
