Sharpening procedure
Set all the work head scales to zero. Fit
the slitting saw and have the setting plate
on top, loosely clamp in place. Loosen the
universal base plate clamp and slide it all
forward until the setting plate is in contact
with both sides on the grinding wheel;
I fi nd moving the spindle forward is the
easiest way of achieving this. Rotate the
slitting saw until a tooth lines up with the
radial edge of the window. Concentrate on
the point of the saw tooth especially if the
gullet is angled then lock it all tight with the
top clamping screw. Move the base plate
away from the wheel to avoid any possible
damage to it, fi t and adjust the detent
assembly and get it located in a convenient
saw tooth gullet, photo 15. Now remove
the setting plate, rotate the whole work
head to get the required tooth clearance
angle. Bring the saw close to the wheel and
set the stop if needed to avoid catching
the next tooth with the wheel; this will be
easier when you have made the penguin
stop which is to follow later. Switch on, add
cut and grind the fi rst tooth, keeping a
constant pressure with your hand to ensure

‘Universal’ Tool
and Cutter Grinder
Graham Sadler modifi es an engraving cutter grinder to be more versatile.
Setting a slitting saw, note the position of the cutter edge in the setting window and the
pressure on the detent causing it to bend.The start of the grinding process, an
obviously blunt and sad 10mm slot drill Use a mini disc to enlarge the gash if needed
