1 Bondstrand Taper Tool II For 8-16 Bondstrand 3000 Series Product Lines General Taper-Tool II: Fixed Motor Model Taper-Tool II is a precisely engineered tapering machine designed to accurately grind a taper which will mate with the other system components for 8-16 pipe, Bondstrand Series 3000/3000A, 3200/32000A and 3300/3300A. The original model Taper-Tool II has the motor mounted on the grinding drum while the newer Taper-Tool II has the motor separate from the grinding drum. The high speed motor (120V AC/DC) and diamond surfaced grinding drum assure a smooth and uniform taper for maximum bond strength. Taper-Tool II: Remote Motor Model As with all precision equipment, care during use and proper storage are very important in order to maintain the equipment in good working order. The Taper-Tool II is designed to give many years of service when maintained properly. Preparation In the process of field fabrication, proper cutting and tapering is essential for correct installation and performance. 1. For all cutting and tapering, the pipe must be held securely with a strap wrench, saw guide/clamp assembly or a chain vise. When a chain vise is used to hold the pipe, always wrap the pipe with protective material (rubber) to prevent damage to the outer surface. 2. Cutting 8-16 pipe should be done with a power driven circular abrasive cut-off wheel. Note: Reference Safety Recommendations on the back of this brochure. 3. The cut made on a pipe must be as straight as possible to ensure a proper tapering. Saw guides are recommended, but when not available, a wrap-around may be used to scribe or mark a cutting guideline. See Table 1, page 4. fgspipe@nov.com

in the two Spiders (1 &10). There are pins for each of the pipe sizes, 8, 10, 12, 14 and 16.

The 8 pins are slotted to be tightened or loosened with a coin, not a screwdriver.

Check that the mating surfaces of the pins and spiders are clean prior to installing different pins.

Adjustment is made by loosening the Allen Screw (54) and sliding Sleeve (55) and Housing (48) down the shaft.

Loosen bolts (44) to adjust taper angle, and then retighten.

2 Pipe Protected In Chain Vise Saw Guide Used for Square Cut Wrap Around Used for Marking Tape Taper Tool Set-Up The tool comes packaged with nine 8 Extension Pins (Refer to numerical identification key Figure 1, Part 9) installed in the two Spiders (1 &10). There are pins for each of the pipe sizes, 8, 10, 12, 14 and 16. The tool will not fit into the storage case with any size pins larger than 8 installed. The 8 pins are slotted to be tightened or loosened with a coin, not a screwdriver. The other sizes are knurled to be hand tightened only. Install appropriate size extension pins into the spiders. Check that the mating surfaces of the pins and spiders are clean prior to installing different pins. It may be necessary to reposition the grinding drum to install different sized pins. Adjustment is made by loosening the Allen Screw (54) and sliding Sleeve (55) and Housing (48) down the shaft. The pointer, on the Degree Plate (59) must be set at 2 degrees for standard pipe tapers. Loosen bolts (44) to adjust taper angle, and then retighten. Dropping the tool will result in knocking the set angle off or damaging the tool. Do not drop. Set rear spider at the end of the Extension Tube (3). Loosen screw (2) if necessary to move spider. Next, retract the extension pins fully by turning the Extension Pin Adjusting Knob (22) counterclockwise until it stops. 2

Insert the female end of the drive shaft over the male end of the motor shaft. 5.

Screw the outer flexible drive shaft housing to motor Grinding Drum Connection Insert hexagonal end of drive shaft

After insertion has been completed, screw on the outer casing of the drive shaft.

Screw (54) sliding sleeve and Housing (48) away from the spiders. Temporarily lock sleeve on shaft.

The tolerance is shown in Table 1 on the next page.

3 Motor Connection Motor assembly of the remote motor model Taper-Tool II should be performed as follows: 1. Remove dust covers from Flexible Drive Shaft Ends (57). 2. Push on the male hexagonal end of the drive shaft to extend the female end beyond the drive shaft housing. 3. Rotate motor shaft so the flat side is facing up. 4. Insert the female end of the drive shaft over the male end of the motor shaft. 5. Through hole in motor housing, lock the set screw very tightly on the flat of the motor shaft. 6. Screw the outer flexible drive shaft housing to motor Grinding Drum Connection Insert hexagonal end of drive shaft into the Female Hexagonal Drum Opening (38). After insertion has been completed, screw on the outer casing of the drive shaft. Tighten to a snug fit In order to insert the tool into the pipe, loosen Locking Sleeve (55) by unscrewing Allen Screw (54) sliding sleeve and Housing (48) away from the spiders. Temporarily lock sleeve on shaft. Turn adjusting knob until all threads disappear into housing. It is important that the pipe end be cut square. The tolerance is shown in Table 1 on the next page. Slide Rear Spider (1) into pipe with Extension Tube (3) in a cocked position. Push rear spider into pipe until Front Spider (10) is against pipe. Raise the tool so front spider enters and fits snugly into pipe. Slide the tool until the pipe and the grinding drum are in the proper position. For the original model Taper-Tool II, set pipe within 1 /4 of fully depressed brake button. In the case of the newer Taper-Tool II, set the pipe 1 /4 from the bottom lip of the Grinding Drum Guard (23). 3

If there are six high (or low) spots, this is an indication that the extension pins are too tight and are deforming the pipe.

4 Turn Extension Pin Adjusting Knob (22) clockwise by hand until the tool cannot slip or turn in the pipe. Do Not Overtighten! The pipe can be deformed and an improper taper, or damage to the tool can result. Taper Tool II Operation Plug the electric cord into either a 115 volt AC power source. Test the tool for smooth operation. There should be no vibration. Caution: The motor turns at 20,000 RPM and tapering pipe causes large volumes of dust. Wear a dust mask and goggles. Turn on motor switch. Carefully turn Taper Depth Adjusting Knob (53) counterclockwise until the grinding drum comes in contact with the pipe. Note: Use caution in keeping hands away from the motor, blades and any of the moving pieces. Taper Lengths & Angles The following are the approximate taper lengths for the nominal pipe sizes.

(A oneway internal clutch prevents turning the wrong way). Caution should be exercised to avoid twisting of electric cord. The preferred method of accomplishing this is to use pipe rollers and keep tool stationary. A two man crew, one to turn the pipe and one to operate the tool, would be necessary. For the remote motor model Taper-Tool II, grasp the drive shaft and rotate the tool clockwise around the pipe taking care not to twist the grinding drum thereby changing the taper angle. Rotation should be continuous and uniform. After one complete turn of the tool, repeat procedure of turning taper depth adjusting knob and rotating tool until proper taper length is obtained. Avoid heavy cuts that slow motor down drastically. Be sure tool vibration does not loosen the extension pin adjusting knob. Observe the taper while it is being ground. If there are six high (or low) spots, this is an indication that the extension pins are too tight and are deforming the pipe. Loosen the extension pins until a smooth taper is being ground. Rotate the pipe during tapering to eliminate the effects of high and low grinding. 10 3½ 2 ¼ ¼ 14 4¼ 2 ¼ 16 5¼ 2 5 /16 To stop the tool after proper taper length has been obtained, turn the taper depth adjusting knob three complete turns clockwise to clear the grinding drum from the pipe.

Maintenance Keep your Taper-Tool II clean. Keep all motor passage ways free of dust. The motor must have adequate ventilation during operation or overheating will result. Remove the filter on back of motor to blow or wash clean (fixed motor model). Be sure it is dry before replacing. Do not let any dust get into pistons when changing extension pins. Keep shafts lightly oiled and wiped dry to prevent rust. Periodically the flexible drive shaft should be lubricated with Lubri plate type 807 grease. Keep the tool in the case when not in use. Do not attempt to disassemble the tool except as stated in these instructions. If necessary to contact manufacturer regarding this tool, be sure to refer to the motor serial number. Do s Keep it clean Keep in case when not in use Keep shafts lightly oiled and wiped Keep motor free of dust Keep bolts and screws tight Don ts Use a pipe wrench or hammer on tool Stand directly in front of grinding drum Use any voltage but 115 volt AC/DC Over tighten adjusting knobs. Leave extension pins out Run motor with excess vibration Run motor with no load or over load Lubricate anything but shafts Manufacture of Close Nipples The rear spider should remain at the end of the extension tube except for nipples shorter than 26. For nipples shorter than 26, loosen screw and slide the rear spider into position and retighten screw. An alternate grinding procedure for close nipples is to hold the tapering tool stationary and rotate each nipple by hand or with a strap wrench. Reversing the Grinding Drum The grinding drum is diamond coated and should be turned end for end to extend service life after it becomes dull. This will re-sharpen the drum by exposing new diamonds to the cutting surface. A dull grinding drum can cause overheating of the drum and/or motor. To turn it around, remove guard first and place a strap wrench around the drum. Remove cap and use a socket wrench to remove nut. Note that this is a left hand thread. Pull the drum off the shaft, turn drum and replace. Tighten nut and replace cap and guard. 5

Local exhaust ventilation should be provided at areas of cutting and/or tapering to remove airborne dust and fibers. General dilution ventilation should be provided as necessary to keep airborne dust and fibers below the applicable exposure limits and guidelines. The need for ventilation systems should be evaluated by a professional industrial hygienist. Work area should be kept clean, including floor or other horizontal surfaces. Rinsing with water or sweeping with brushes or brooms (using floor sweep) is recommended. Never use compressed air to clean area or to remove dust for personal cleaning. Brushes should be used to remove residue from shaved surfaces. Personal Protection: Always refer to the Material Safety Data Sheet (MSDS) prior to working with unfamiliar materials or if there are questions concerning the contents of the fiberglass pipe. OSHA regulates glass wool (fiberglass) under the Hazard Communication Standard and as a chemical hazard in laboratories. OSHA classifies glass wool fiber as a Particulate Not Otherwise Regulated, with a workplace permissible exposure limit (PEL) of 5.0 mg/m3 for respirable dust and 15.0 mg/m3 for total dust. These limits are identical to those OSHA requires for construction workers exposed to fibrous glass, which were adopted from the 1970 Threshold Limit Values (TLVs) of the American Conference of Governmental Industrial Hygienists (ACGIH). Barrier creme should be applied to the skin in areas which may be exposed to shavings prior to beginning work. Clean clothes should be worn each day. Do not wear clothing that has not been laundered to begin a work shift. More frequent changing may be required by conditions. Long sleeved shirts or work suits should be used. Tape should be used at sleeve opening. Cotton or flannel shirts under work shirts may be worn to prevent rubbing of skin at opening of work suit. Gloves with elastic cuffs should be worn at all times. Replace worn or contaminated gloves as necessary. Gloves with flared, stiff cuffs act as a gathering funnel for shavings. Pant legs should be worn outside work boots. If necessary for safety purposes, the pant legs can be taped to fit closely to the boot. Over-the-calf socks can be used to prevent chafing of the boot on the skin. Wristbands and watches should be removed to prevent rubbing or accumulation of particles on skin underneath the band. 7

A respirator should be used if ventilation is unavailable, or is inadequate for keeping dust and fiber levels below the applicable exposure limits.

8 A respirator should be used if ventilation is unavailable, or is inadequate for keeping dust and fiber levels below the applicable exposure limits. To protect against dust and fibers, use a NIOSH-certified disposable or reusable particulate respirator with an efficiency rating of N95 or higher (42 CFR 84) when working with this product. For exposures up to five times the established exposure limits use a quarter-mask respirator, rated N95 or higher; and for exposures up to ten times the established exposure limits use a half-mask respirator (e.g., MSA s DM-11, Racal s Delta N95, 3M s 8210), rated N95 or higher. Operations such as sawing, blowing, tear out and spraying may generate airborne fiber concentrations requiring a higher level of respiratory protection. For exposures up to 50 times the established exposure limits use a full-face respirator, rated N99 or higher. Personal Hygiene: Wash exposed skin with soap solution (liquid soap preferred) and cool water. Use washcloth with brushing motion to remove dust or fibers. Do not scrub the skin. This could result in the fibers being imbedded into the skin. Rinse thoroughly with clean, cold water. Apply lotion or creme to skin (non-detergent formulas such as baby lotion) to soothe irritation or prevent further immediate irritation.
