The 87740 motor is the driving force behind some of the most popular pipe threaders in the industry, including the RIDGID® 300 and 535. The Steel Dragon Tools version of the 87740 motor powers the Steel Dragon Tools 300 and 7090i. The 87740 motor is a versatile work horse and can be used across a variety of platforms thanks to interchangeable gearboxes. This motor is reliable, durable, and easy to service should the need ever arise.
The 87740 motor has three main components; the field, the armature, and brushes.
The brushes are the item most likely to wear out first. The brushes are designed to make constant contact with the commutator of the armature. While the brushes are considered a wear item to be replaced on occasion, it is also important to inspect the armature and especially the commutator. After many years of use, the commutator can be worn away due to the constant contact with the motor brushes. This wear will result in a slight indentation in the commutator (fig. 1). New brushes will not be able to make solid, constant contact with the commutator, resulting in sparking, higher current draw, and loss of power. If the commutator shows this type of wear, it is easier and more cost effective to replace the entire armature.
The motor field is not a wear piece and will rarely need to be replaced unless it is damaged. Damage is most likely to occur during operation or maintenance. The field can be damaged by an electrical surge or if an internal wire is pinched.
Steel Dragon Tools offers replacement parts that will fit any 87740 model. Steel Dragon Tools is also a full-service repair shop specializing in reconditioning pipe threading machines. Steel Dragon Tools technicians have decades of experience and can quickly diagnose and repair most 87740 motors.

Steel Dragon Tools offers several different models of wire strippers. The two entry level options are the WRA10 and the WRA15. Both models can be operated manually with a hand crank or automatically with a drill. The WRA10 and WRA15 are an ideal entry point for anyone looking to strip wire and increase recycling payouts on scrap metal.
The WRA10 is small, at 6-inches in height it is almost pocket size. But behind the diminutive size is an easy to operate machine that will quickly and cleanly strip up to 450 inches of wire per minute when connected to a drill. The WRA10 will strip wire up to roughly 1/2-inch in diameter.
The WRA15 is the more traditional benchtop model. It boasts a larger size and wire-stripping capability. Standing at 12-1/2-inches in height it will also strip up to 450 inches of wire per minute when connected to a drill. The WRA15 will strip wire up to roughly 1-inch in diameter.
Set Up is Key
Set up is the most important step to successfully strip wire. Following these tips will help make the wire stripping process quick and easy. These tips apply to both the WRA10 and WRA15.

A die head (or two) is a requirement for most industry-standard pipe threading machines. Using a Steel Dragon Tools 300, 300C, 7090-PRO, 7090i, 7090e, or a RIDGID® 300, 300A, 500A, 535, 535A, 800, 801, 802, or 1822 pipe threading machine will require a die head. Pipe threading professionals can choose between the 811- or the 815-style die head. (Most 811- and 815-style die heads are now being manufactured with automatic oiling operation, designated by the letter A — more on this next week.)
The main difference between the 811 and the 815 comes in operation. The 815 die head has a trigger mechanism that will automatically open the die head and stop the threading process once a certain number of threads have been cut. The 811 die head has a quick open lever that must be opened manually to stop the pipe threading process. Both die heads can be used to thread pipe and bolts, both thread in the right-hand direction, and both have the same threading capacities.
Seems like an easy choice, right? However, the 811 die head allows for a flexibility in threading that the 815 cannot accommodate. The 815 die head will always cut the same number of threads per pipe size before the pipe hits the trigger and stops the threading process. The 811 die head can thread further down the pipe should the need arise.
The 811 die head will also be more reliable in the long run since there are no extra mechanical pieces to break or malfunction. Price-wise, the 815 will be slightly more expensive than the 811 but not by much.
Steel Dragon Tools manufactures an 811A and 815A die head that will fit most industry standard pipe threading machines including Steel Dragon Tools and RIDGID® machines. Steel Dragon Tools 811A and 815A die heads are offered with an automatic oiling feature for use on pipe threading machines that have a pipe threading oil reservoir.

One of the common complaints from users of the Steel Dragon Tools Reconditioned RIDGID® 535 is that the chuck or the pipe wobbles, resulting in unusable threads.
If the machine is not threading properly, check the dies first. A good set of dies should last a very long time. Unless the die teeth are chipped or otherwise damaged, the dies should work without issue. Next, check the installation. Dies will fit into the die head only one way but should be installed securely and in the proper order. If the dies are installed properly, check the rear centering chuck. The rear centering chuck simply keeps the pipe centered in the machine. Do not over tighten the rear chuck. Only hand tighten the rear chuck, do not use tools.
The front chuck does most of the work when threading pipe. The front chuck should only be hand tightened. Do not use tools to tighten the front chucks.
To tighten front and rear chuck, spin chuck forcefully in a counter clockwise motion. The chuck will tighten around the pipe. Do this several times to ensure a snug fit. The sound the that the chuck makes will change as it tightens. Once the sound changes, the chuck is tight. A tightened chuck will give off a short, dull sound as the chuck has already tightened around the pipe.
Other Tips to Remember:
The guide marks on the die head are not exact. Always run a simple threading test before threading the actual work piece. Use a properly-sized fitting to test the threads. A properly threaded pipe will allow the fitting to turn one and a half to two turns before meeting any resistance. If the fitting continues to turn easily or does not turn at all, the die head settings will need to be adjusted.
Threads should only be cut to the width of the die head. Cutting threads too far down the pipe may result in unusable threads. Some dies are designed to cut tapered threads. Cutting beyond the width of the die head will result in straight threads instead of the desired tapered threads.

The Steel Dragon Tools 819 is a nipple chuck adapter used to create pipe nipples on 1/2-inch to 2-inch pipe. The Steel Dragon Tools 819 can be used with both RIDGID® and Steel Dragon Tools pipe threading machines, including model numbers 300, both power drive and compact, as well as 535, 1882, and 1224.
The Steel Dragon Tools 819 package includes a nipple chuck wrench, adapter hanger for storage, standard insert and five adapters: 1/2 in., 3/4 in., 1 in., 1-1/4 in., and 1-1/2 in. The base itself serves as the 2-inch adapter.
To create a pipe nipple, install pipe into the threading machine and thread pipe as normal. Cut the pipe to the desired length. Install the Steel Dragon Tools 819 nipple adapter into the pipe threading machine and screw the threaded end of pipe into the adapter. Do not over-tighten the pipe into the nipple adapter. Hand tight will be sufficient. Once the pipe is secure in the adapter, thread it as normal.
It is important to make sure the initial thread is the correct dimensions. If the threads are over-sized or under-sized, the pipe may become lodged in the adapter. Removing a lodged pipe will require a pipe wrench and considerable force. Test the threads with a thread gauge or corresponding fitting to ensure the threads are dimensionally correct. A fitting should turn 1-1/2 to 2 turns on a properly threaded pipe.
Insert the plug end of the nipple chuck wrench into the holes in the adapter to release the tension spring inside the adapter. Unscrew the pipe from the adapter while relieving the tension. A pipe wrench may be required to unscrew the pipe from the adapter. The pipe can become lodged in the adapter if the threads are not dimensionally correct. The pipe will tighten by itself in the adapter during the threading process.

Steel Dragon Tools manufactures high speed steel and alloy dies to meet or exceed industry specifications. These dies are compatible with Steel Dragon Tools pipe threading machines and can be used in compatible dies heads with other machine brands.
Dies are an essential part of the pipe threading process. Sharp, well-made dies will ensure consistent, useable threads. Dies with dull or chipped teeth will result in poorly threaded pipe that will not seal properly. Replacing dies as they wear or chip is a necessity but it doesn’t have to break the bank.
Steel Dragon Tools dies are compatible with the specified Steel Dragon Tools pipe threaders and will fit certain other brands. Steel Dragon Tools dies will match the quality of comparable dies but for a fraction of the price. Steel Dragon Tools can offer dies for far less since there is no middle man. Steel Dragon Tools manufacturers the dies and then sells them directly to the customer. Buy an extra set of dies and never worry about chipping a tooth while on the job site.
Steel Dragon Tools manufactures dies for powered and manual pipe threading machines. Many of these dies can be used in compatible die heads from Wheeler Rex® and RIDGID® machines.
