to use the supplied T-bolts and hold-down clamps.
Note: The T1243 can be vertically mounted direct-
ly to a machine table, but its table rotation will be
limited. For full 360° rotation, place two parallel
step blocks (not included) at least 1" tall under the
T1243 before mounting to the machine table.
Make sure cross-slide rotary table is secured
to milling table. Check T-bolts and clamps
for tightness before each cutting operation.
If cross-slide rotary table is not secured,
serious personal injury and damage to your
mill and cross-slide rotary table could result.

To mount T1243 vertically:
1. DISCONNECT MACHINE FROM POWER!
2. Rotate T1243 Y-axis forward so rotating table
clears milling machine table.
3. Place T1243 on milling machine table with
T-slot key in middle T-slot.
Note: For full 360° table rotation, place
T1243 on (2) parallel blocks at least 1" tall.
4. Insert (1) M10-1.5 x 60 T-bolt in each milling
machine table T-slot.
5. Install (1) hold-down clamp (or (1) accessory
step clamp), (1) 10mm flat washer, and (1)
M10-1.5 hex nut on each T-bolt (see
