Description and Specifications

Description

REED RGCOMBO2 Roll Groover is designed to form standard rolled grooves in steel, stainless steel and aluminum pipe, from 1 1/4” to 6”, in both Schedule 10 and Schedule 40 pipe. The groove is formed by the groove roll which is fed into the pipe wall. The pipe is supported on the inside by a drive roll, which is relieved to permit pipe wall deformation. The formed grooves comply with the specifications required for mechanical coupling systems. The only adjustment required is for the depth of the groove.
Designed for portability, the RGCOMBO2 Roll Groover is an economical solution to the job-site grooving requirements in mechanical piping system installations. Although the RGCOMBO2 design has many improvements over similar competitors’ models, it is not intended for production work in the fab shop.

Adjusting Groove Depth

Note: To insure the proper groove diameter, a trial groove should be performed.
Note: The Adjusting Screw must be set for each diameter of pipe.

1. Loosen Adjusting Screw (counterclockwise) enough to permit advancing of the Groove Roll down to the pipe.

2. Advance Feed Screw (clockwise) until Groove Roll is snug against top of pipe. Be sure Groove Roll contacts pipe and Adjusting Screw head does not bottom out.
   Note: Trial groove pipe should be deburred for best results. Burr on inside of pipe will raise pipe away from drive shaft, causing inaccurate set- up adjustment. After proper groove depth has been verified by trial groove, deburring of following pipes is not required.

3. Using the Depth Gauge labeled with the pipe size being grooved, place Depth Gauge under head of Adjusting Screw using the flat gauge slot.

4. Advance Adjusting Screw downward until underside of head touches Depth Gauge.

5. Remove Depth Gauge.
   Note: It may be necessary to readjust Adjusting Screw after trial groove is made. Each 1/4 turn of Adjusting Screw will produce a .02” change in diameter of rolled groove. Tightening Adjusting Screw will increase groove diameter. Loosening Adjusting Screw will decrease groove diameter.

Forming the Groove

1. Place the power drive switch in the reverse (REV) position for counterclockwise rotation of the drive shaft and pipe.

2. Step on power drive footswitch and apply light pressure on pipe by advancing Feed Screw with the Straight Ratchet Wrench.
   Warning: If pipe tends to “walk off” the tool.

   • Verify the pipe sits level, if not level then correct.
   • Verify the pipe rotates in the direction shown by the sticker on the tool.
   • Offset the far end of the pipe toward the operator’s side (the side with the power drive REV/OFF/FOR Switch). A pipe offset of 1 inch per 10 ft. should work.
     Caution: Keep hands clear of the Power Drive Hand Wheel/Chuck and Roll Groove Handle area while the tool is in operation.

3. With pipe tracking properly and end of pipe against cover plate, step on footswitch and begin advancing Feed Screw with Ratchet Wrench, allowing one complete rotation of pipe between strokes of Ratchet Wrench.
   Caution: Do not over-feed. Allow one complete rotation of pipe between advances. See Table 2 for details.

4. Continue feeding until Adjusting Screw makes contact with the top surface of the Roll Groover. Allow pipe to make two complete rotations in bottomed position to insure uniform groove depth.
   Warning: Do not tighten Feed Screw after Adjusting Screw bottoms out. Damage to the Adjusting Screw may result.

5. Release footswitch to stop machine, and begin retracting Feed Screw by turning Ratchet Wrench counterclockwise. Retract Feed Screw enough to remove pipe from machine.

6. Measure groove diameter at two places 90° apart. Both measurements should be within the listed tolerance of the dimension.

7. To increase groove diameter tighten Adjusting Screw. To decrease groove diameter loosen Adjusting Screw. Each 1/4 turn of Adjusting Screw will change groove diameter by approximately .02”.
   Note: Once groove depth has been set, following grooves will be same depth.

8. Periodically check groove depth with a mechanical coupling. The coupling should fully seat in the groove without binding or excessive play.

Roll Grooving Tips

1. If pipe tends to “walk off” drive shaft, increase lateral offset of pipe.
2. If Cover Plate shaves end of pipe, decrease lateral offset of pipe.
3. If pipe end flare is excessive, lower pipe end to level with roll groover.
4. If pipe wobbles and/or “walks off” Drive Shaft, raise pipe end to level with roll groover.
5. Short lengths of pipe (under three feet) may require slight hand pressure to maintain the lateral offset.

Manual Grooving Instructions

1. Situation:

   • Pipe secured to vise: Securely mount pipe vise (chain type) on a secure stand or workbench. Allow the pipe to overhange the vise 5 to 12″ so the tool will rotate freely and not contact the vise.
   • Pipe installed (grooving in place): Verify the pipe hangers can accommodate the weight of the RGCOMBO2 plus the manual effort required to operate the tool.

2. Mounting the Tool

   • Retract the upper roller by turning the Feed Screw counterclockwise.
   • Insert the Drive Shaft into the pipe with the Groove Roll on the outside.
   • Draw the rolls closer together by turning the Feed Screw clockwise until the Driveshaft and Groove Roll contact the pipe lightly.
   • Notice the “Pipe Direction” arrow etched on the tool slide block.

3. Set Groove Depth
   Note: To insure the proper groove diameter, a trial groove should be performed.
   Note: The Adjusting Screw must be set for each diameter of pipe.

   • Loosen Adjusting Screw (counterclockwise) enough to permit advancing of Groove Roll down to pipe.

   • Advance Feed Screw (clockwise) until Groove Roll is snug against top of pipe. Be sure Groove Roll contacts pipe and Adjusting Screw head does not bottom out.
     Note: Trial groove pipe should be deburred for best results. Burr on inside of pipe will raise pipe away from drive shaft, causing inaccurate set- up adjustment. After proper groove depth has been verified by trial groove, deburring of follow-ing pipes is not required. See Step 1 of “Pipe Preparation”.

   • Using the Depth Gauge labeled with the pipe size being grooved, place Depth Gauge under head of Adjusting Screw using the flat gauge slot.

   • Advance Adjusting Screw downward until underside of head touches Depth Gauge.

   • Remove Depth Gauge.

   • Note: It may be necessary to readjust Adjusting Screw after trial groove is made. Each 1/4 turn of Adjusting Screw will produce a .02” change in diameter of rolled groove. Tightening Adjusting Screw will increase groove diameter. Loosening Adjusting Screw will decrease groove diameter.

4. Forming the Groove

   • Advance the Feed Screw the amount specified.
   • Using the Socket Extension and Bent Handle Ratchet, turn the Crankshaft so the pipe feeds into the tool as indicated by the arrow.
   • Make one complete revolution of the tool around the pipe before advancing the Feed Screw again.
   • Continue grooving until you reach the desired depth. (The Adjusting Screw can limit Feed Screw advance see the section on Adjusting Groove Depth for details).

5. Dismount the tool, retract the Feed Screw fully, lift and remove the tool from the pipe.
