Tapping & Drilling Machines
G. Place chain hooks and swivels into slots on both sides of the
chamber.
H. Connect the chain to one of the chain hooks, bring chain under
the pipe and connect on the other side to the nearest link.
Do not twist or create kinks in the chain.
I. Hand tighten nuts.
NOTE:
Use additional chain extensions and clevis for diameters over 16".
3.
Position chamber at desired angle.
Tighten down chain nuts evenly, using REED CW12 adjustable
wrench.
A. Ensure the gaskets make good contact.
B. Verify chain holds the machine securely on the pipe and
saddle.
4.
Insert tool into Boring Bar.
A. Push knockout pin in Boring Bar to its holding position.
(Toward flat side of bearing)
B. Insert shank end of drill tap and align pin with slots in bar end.
C. Make sure tool is securely seated and lightly tighten the tool
retaining screw.
D. Retract tool end of Boring Bar all the way into the top cap.
E. Generously coat tap with REED #98425 Tapping Compound.
5.
Assemble top and bottom halves
A. Verify:
a. Swing valve open.
b. Upper ball valve shut.
c. Needle valve (with star knob) shut.
B. Screw Boring Bar top cap hand tight onto the top chamber
(1 3/4 Turns).
C. Push down Boring Bar slowly until bit touches the pipe.
D. Install the thrust bearing.
E. Place the Yoke over the bearing. Adjust the Star Feed as
necessary. Ensure Boring Bar rests in a position past the
detent pins. This will ensure the Yoke fully engages the
Bearing.
F. Put ratchet wrench on top of Boring Bar.
6.
Drilling and Tapping
A. Preparing to Drill
a. Manually: Adjust the ratchet wrench to turn clockwise.
b. Power Drive: Reed 98427 Power Drive Adapter (#98427)
will fit onto RIDGID® brand 700 or the Collins® power
drives. When using this adapter, the operator can control the
feed rate for drilling.
B. Drill through the pipe by pulling the ratchet wrench clockwise
and turning the star feed clockwise in a smooth and
consistent manner. An easily turning Boring Bar and star
feed indicates one has completed drilling through the
pipe wall.
C. If appropriate, open the ball valve to allow flushing of chips
while drilling.
D. Feed drill tap down until feeling resistance. One will feel
resistance when the tapping threads contact the pipe wall.
E. Begin tapping by rotating the ratchet wrench.
F. Continuously turn the feed housing. Rotate in a smooth and
constant manner. DO NOT FORCE the star feed. Forcing
the star feed will strip off the threads.
G. Continue tapping until start of the 3/32" wide groove in the
Boring Bar sits flush with the Main Body. This depth should
result in a satisfactory tap. Resharpened drill taps may
require two additional turns. Other manufacturer's drill taps
may vary. Consult drill tap manufacturer's instructions.
1110-59300
Consider conducting dry taps to determine a depth that
works best for you.
7.
Tool Removal
A. Reverse the ratchet detent lever (or Power Drive Switch) and
carefully back the tool out of the tapped hole using a
counterclockwise rotation.
B. Once the tap is free of the pipe, retract the Boring Bar to its
uppermost position.
C. Close the swing valve by pushing down on the handle and
turning it 90 degrees counterclockwise.
D. Open the pressure relief valve on the top chamber to
release pressure, then close it again.
E. Unscrew the top cap assembly from the valve chamber.
F. Loosen the tool retaining screw and strike the end of the
knockout pin to release the drill tap.
8.
Attaching Corporation Stop to Boring Bar
A. Verify the selected corp stop matches the size intended and
the drill tap size.
B. Shut the corp stop.
C. Screw the corp stop and corp adapter together. Screw the
adapter shank to the corp adapter.
B. Push knockout pin in Boring Bar to its holding position.
(Toward flat side of bearing sleeve.)
C. Insert tapered end of the adapter shank into the Boring Bar
and align the pin with the slots in the bar end. Tighten the
tool retaining screw.
D. Make sure the Boring Bar retracts all the way into the top
cap. Apply non-toxic pipe dope to corp inlet threads.
E. Screw assembly into the valve chamber.
9.
Inserting the Corp Stop
A. Attach the ratchet wrench onto the Boring Bar and set it for
clockwise rotation.
B. Turn the star knob counterclockwise 1 turn to balance the
pressure.
C. Push down on the swing valve handle and turn 90 degrees
clockwise.
D. Push the Boring Bar down until the corp stop threads touch t
he pipe.
E. If not already done, swing Yoke over the Boring Bar to
engage the bearing. Feed the bar as needed.
F. To start the engagement, rotate the Boring Bar clockwise
while carefully turning the feed housing clockwise. Once the
threads are engaged, disen- gage the Yoke. Continue
rotating until the corporation stop feels solid. Do not attempt
to permanently tighten the corporation stop with the
machine
10. Releasing the Corporation Adapter
A. Reverse the ratchet to turn counterclockwise.
B. Remove play from the ratchet wrench with one hand, and
strike the wrench handle with the other hand to disengage
the corporation adapter from the adapter shank.
D. Rotate the ratchet wrench counterclockwise until the adapter
shank is completely free.
E. Verify quality of corp stop seal by opening the chip flush
valve and attempting to release pressure in the chamber. If
pressure does not drop and water continues to flow,
re-engage to corp stop with the boring bar and attempt to
tighten the corp stop further.
