MAKE SURE CHIPOUT AND DRILL ARE ALIGNED PROPERLY!
ADJUSTING BACKSET TURRET BOLTS:
The drill and chipout block must align with the drill or the chipout block will
become egg shaped. In other words, the two short bolts may not be the same, but
they need to each be 3/8" shorter than their respective middle bolt, and 2 5/8"
shorter than their respective long bolt.
Extensions for the chipout shafts and the face drill bearing shafts are included for
drilling a 5" backset. The extensions are stored beneath the bolt drill. They can
be left in place on their respective shafts if you do not need the additional
clearance for machining narrow doors.
TWO STAGE FACE DRILLING
It is possible to drill two different diameter holes with the same cutting
tool. The drawing represents a 2 1/8" counter bore bit mounted on the
shank of a smaller diameter bit. Care must be taken that 2 1/8" be
maintained between the tip of the ring cutter teeth and the teeth on the
main cutter or door face tear out will result.
You may need to adjust the bit's depth position in the collet.
TO ADJUST:
(1) Slide the bit in or out, and relocate the collar so you will have a
reference for the next time you use this set up.
(2) Adjust the limit switch arms (REG and DEEP trigger points), or the actuating rod that trips the
arms. The limit switch actuating rod is threaded and drilled to accept a 1/4" shank stop pin. With a
3/16" stop pin installed the machine is properly adjusted for machining 1 3/8" thick doors or, with
no stop pin installed for machining 1 3/4" thick door. MAKE SURE THE CORRECT STOP PIN IS
INSTALLED FOR THE THICKNESS OF THE DOOR YOU ARE MACHINING.
Turning the selector switch to
REG allows the smaller bit to
drill through the door - but not
so deep that the counter bore
touches the door. "DEEP"
sends the counter bore all the
ay through the door until it
just etches a groove in the chip
out block.
