This is all sounding great, but I need to see this idea in action and motion.

The allen screw and small washer are not shown. >>> >>> [image: Connecting Rod Hardware] >>> >>> The connecting rod is attached to the slider with the threaded locking >>> tab inside the groove of the slider, and the connecting rod bushing on the >>> outside of the slider. The connecting rod should move freely on the >>> bushing. The opposite end of the connecting rod has a pvc block with a >>> split pin and a magnet installed in the face. The pin fits inside a hole in >>> the index plate, and the magnet holds the connecting rod in place. >>> >>> The slider assembly should look like this when completed. The duplex >>> gear is not shown: >>> >>> [image: Connecting Rod Details] >>> >>> The connecting rod should now be hanging down from the slider assembly. >>> >>> Installation is now complete. >>> Basic Setting: >>> >>> In this section I will cover basic settings for using the Wave >>> Attachment. >>> Setting the Pitch of the wave: >>> >>> Start by setting the pitch of the X-axis screw by choosing the >>> appropriate Legacy spiral gear. 4"-6" of pitch is a good starting point. >>> >>> See the notes at the end of the page for more information. >>> Setting the offset: >>> >>> Loosen the allen screw and slide the bushing and connecting rod to the >>> desired offset. You can choose either side of the center of the duplex >>> gear. Lock down the allen screw. Do not over tighten the screw. A little >>> offset adjustment goes a long ways.

Please check your installation for any problems. *** >>> Adjusting the Duplex Arm: >>> >>> Now, adjust the duplex gear arm so that the X-axis gear is engaged with >>> the directional gear, and the large outside duplex gear is engaged with the >>> directional gear. Adjust the duplex gear arm so that the inner smaller gear >>> of the duplex gear is DISENGAGED from the main drive gear. As with all >>> things Legacy, the gear train should be loose enough to freely turn, but >>> not so loose that the gears will disengage during machining. The duplex >>> gear may be adjusted nearer or farther from the main gear depending on the >>> amount of offset on the slider. Check for binding when the bushing on the >>> slider is in the 8:40 position and the connecting rod is located on the >>> index plate. It should be obvious once you install the connecting rod for >>> the first time. >>> >>> [image: Duplex Gear Adjustment] >>> >>> NOTE ***As a final check, the gear train when activated should now make >>> the spindle rock back and forth.

The cause is the duplex gear is allowing the gear to flop around a >>> bit under the strain of changing directions. This causes the duplex gear to >>> rub the main drive gear occasionally. A future design includes the proper >>> support of the duplex gear on the duplex adjusting arm with an additional >>> bearing, or possibly a bearing included in the slider spacer.
