9. After test cut has been completed and desired results are
achieved, ensure both 10-32 SHSS are secured in place.
10. It is important to note to not remove too much material, i.e.,
do not force the cutters into the cartridge case as this will
generate an excessive amount of material being removed
and will damage the cartridge case. Use small adjustments
and when slight resistance is felt, i.e., cutter is in contact with
case, secure cutter and conduct a test cut.
11. If the desired results are not being achieved using this process,
and more of deburr or chamfer is desired, this can be done by
simply lifting the case off of the cutting face slightly before
advancing the cutters, then advance cutter until cutting edge is
in contact with case
(see Fig. 14 & 15)
. This will allow the cutter
to be positioned to remove more material. If using this method
perform a test cut by hand, if unable to rotate cutter and produce
cut, then too much material is trying to be removed so the cutters
will need to be repositioned to take less material. Remember
small rotational adjustments are all that is required; 1/16-1/8 of
a turn.
12. After cutter has been set correctly and desired results have
been achieved it is time to place your VLD 3-Way Cutter on your
Case Trimmer. Follow your case trimmer instructions for proper
removal and installation of cutters.
13. Once cutter has been installed on the trimmer, and before desired
trim to length is set, insert the same case previously tested by
hand and run a test cut on trimmer, at low RPM. Inspect case and
ensure cutter is producing the desired cut, if not readjust cutter
as needed, following instructions above.
14. When all adjustments have been made and cutter is producing
the desired results, loosen the 8-32 SHSS securing the pilot
and lower pilot onto the top post of the Facing/Deburr cutter.
Tighten the 8-32 SHSS to secure the pilot. Next, adjust your
trimmer to the appropriate cartridge case trim to length and
begin trimming your cases.

7. Test cutter on case to ensure all cutting edges are making contact
and brass is being removed on the face and on the inside and
outside of case mouth, to the desired amount.
DO THIS BY HAND
TO ENSURE THE CUTTERS ARE SET PROPERLY AND TO PREVENT
DAMAGING BRASS IF CUTTERS WERE SET INCORRECTLY
.
Excessive chamfer and deburr will produce an undesirable sharp
edge, if this happens readjustment of cutter is required
(see Fig. 11
& 12)
.
8. Slight adjustments may be necessary to increase/decrease
chamfer on outside of case mouth or increase/decrease deburr
on inside of case mouth. To do this simply loosen the 10-32
SHSS securing cutter and rotate drive screw in or out using small
increments (1/16-1/8 of a turn) to reposition cutter, using the 3/32”
hex wrench. The drive screw has a thread pitch of 48, meaning one
complete revolution will advance the cutter in or out by .020”, thus
a quarter turn of the drive screw will yield .005” of inch of travel
inward or outward
(see Fig. 13)
.
Note
: before the 10-32 SHSS screw is loosened, remove the
backlash in the thread by leaving the 10-32 setscrew tightened
against cutter and rotate the drive screw in desired direction.
Example: If there is still a burr on the inside of the case mouth the
cutter would need to moved outward to remove more material
from inside case mouth
. Leaving the 10-32 setscrew secured
in place, rotate the drive screw counterclockwise taking up
any backlash in thread.
DO NOT FORCE
as soon as you feel
resistance stop, all backlash is removed. Loosen the 10-32
SHSS screw and rotate drive screw 1/16 of a complete rotation.
Secure the 10-32 SHSS and repeat

3. Using a 3/32” hex wrench, rotate the two
Drive Screws to position the cutters as
shown, in
Fig. 5-7
. Clockwise rotation
advances cutter towards pilot and
counterclockwise rotation advances cutter
away from pilot. This initial adjustment is
to move the cutters into a position that
will allow for the cutter to be set for the
desired case to be trimmed.
4. Using a sized and expanded cartridge case, place over the pilot
and onto the Facing/Deburr Cutter as shown in
Fig. 8
. This case
will be used to adjust cutters.
5. Using a 3/32” hex wrench rotate Drive Screw to position Chamfer
cutter to where it is just making contact with the outside of
the cartridge case, this will aid in supporting the case.
Once cutter is positioned properly secure cutter in place with the
10-32 SHSS
(see Fig. 9)
.
6. Using a 3/32” hex wrench rotate Drive Screw moving the Facing/
Deburr Cutter outward to where the cutter just makes contact
with the inside of the case mouth,
DO NOT EXCEED
.
Once cutter is positioned properly secure cutter in place with the
10-32 SHSS
(see Fig. 10)
