Juki DDL-8700-H Industrial Straight Stitch Sewing Machine, K.D table & Servo Motor DIY

1 hour or less assembly instructions,br>First, make sure you have a drill, hammer, and wrenchbr>In the drawer, you'll find all the necessary hardware,br>14 bolts for the legs,br>2 small bolts for the pedal,br>Set of 2 long brackets for the 2 legs,br>Set of 2 small brackets for the bottom brace,br>Set of 2 L brackets for the pedal,br>4 pcs The table may have been pre-drilled for the motor depending on your machine. If that's the case, simply align the motor mount with the table's holes. If your table was not pre-drilled for the motor, simply mark the mounting holes and use a 3/8′′ drill to drill three mounting holes. Before drilling the mounting holes, make sure your belt pulley is centered with the cutout on the table. Tighten down the motor mount to the table using the long bolts that came with your motor. br>Step 2: Connecting the On/Off Switch Boxbr>If you're using a servo motor, you might not need to do this step! The switch could be incorporated into the motor's front. br>Take measurements over a 10-minute period. Place the on/off switch box 1/2′′ from the front right corner of the table and screw it to the table. br>Fasten the wire from the switch box to the motor in the same manner as shown in the diagram. br>Step 3 Leg Assemblybr>To assemble the legs for the stand, measure 29 inches from the top of the leg to the bottom. 1/4" tall (7 lines from the top)br>When you're done putting the stand together, you'll have a table that's about 31 inches tall. This is the standard height at which we construct all of our stands. Attach the bottom (smaller) brace to the legs and the cross (wider) brace to the back of the legs. br>Step 4: Attaching Legs to Table Topbr>Assemble the legs and place them on top of the table as shown. br>After that, attach the legs to the table top, making sure they are centered front to back in the stand.br>Lastly, attach the treadle (motor pedal) to the bottom cross brace, centered over the motor, as shown in the picture below. br>Connect the treadle rod to the motor's arm with the treadle rod. br>Some stands may or may not include a plastic drawer where extra bobbins, needles, scissors, or tools can be stored. To attach the drawer to the table top, center it on the longer side opposite the motor and use the included side mounting rails. br>Assemble the stand by connecting the two thread stand posts with the coupling, then adding the thread stand arms and attaching the thread stand cone platforms to the arms. br>Step 7: Installing Your Machine in the Stand.br>Depending on your machine, you may need to use small finishing nails to attach small rubber or felt cushions to the table. Attach the machine's metal head hinges to the back of the machine and wrap the belt around the machine's belt. Place the machine in the cutout and tilt it back to wrap the belt around the motor pulley. When the belt is pressed in on itself, there should be about an inch of space between the belt and itself to properly adjust the tension. If the belt is too tight, adjust the motor bracket to raise the height of the motor; if the belt is too loose, adjust the motor bracket to lower the height of the motor.

It does a decent job. I've sewn silk and superlight poly with no problems, but if you're going to sew a lot of delicates, I'd recommend switching to nylon feed dogs. If you aren't careful, the factory ones will eat your fabric.

Without a doubt. This is an 8700H with a servo motor (servo motors allow for variable speeds). It has a more powerful motor that's designed to work with multiple layers of leather. The 8700 model is for lighter leather and has a less powerful motor than the 8700H.
