There are several hazards you need to be aware of when using a sewing machine.

  • Keep your fingers away from moving parts.
  • Never place your finger under the needle.



Description

There are currently four Janome 3160 QDC sewing machines available for use in the Maker Hub. These machines feature 60 different stitch patterns. It has automatic fabric feeding, one hand needle threader and easy to follow instructions, making it an ideal machine for first time sewers. Some of its more advanced features include buttons for lock stitch, needle up or down and automatic thread cutting. It has a add on platform that can be attached to make sewing larger materials a breeze.


Here is an example of this piece of equipment being used.

Terminology

  • Spool - Holder used for thread.
  • Bobbin - Cylinder or spindle holder in which thread is wound thread that comes from the bottom
  • Presser foot - piece of metal that keeps fabric in place when sewing.

Training

All information on these specific machines can be found in the User Manual and on the Product Home Page

How to set up the machine. This video shows a similar set up process to our machines, but be sure to compare to the manual.

YouTube is a great resource for learning new things. If you are new to sewing, try watching a few videos to get a general understanding before jumping into sewing.

Operation

Winding the bobbin

  • Once you picked the type/color of thread spool, first get some of it loose and out and secondly place it on the large spool holder (skinny tub). Then, add the spool cap. It's side will depend on the type/ style of thread spool you picked.
  • As you follow the guide images, put the thread around the metal knob (upper thread guide). Then slide the thread through one of the holes in the bobbin and place it in the bobbin winder spindle (small metal tube) that its on the right top of the machine. Slide the bobbin winder shaft over to lock it.
  • Hold the thread for couple seconds at the beginning as you press the foot pedal gently and slowly. Once it becomes even or uniform, you can let go of the thread and go faster with the foot pedal.
  • Cut the thread once you are done and place the bobbin in the bobbin case. The drop in bobbin is covered by a plastic cover that you can remove by gently pulling the hook cover release button. Drop the bobbin and wrap the thread around a the clip under the plastic cover. Then, put the cover on.

Threading the machine

  • Grab onto the thread from the thread spool and run the thread through the knob and going down then up, following the image guide around and make sure it is catching all parts. At the end thread the needle.

Demonstration

The demonstration will include several steps. Demonstrate you can safely setup the sewing machine, which includes winding the bobbin, threading the machine, and removing/replacing the needle. Finally, sew a mini pillow.

General Procedure

  1. Wind the bobbin and thread the machine
  2. Pick two pieces of fabric and turn them right sides together (flip them) because the raw edges will be inside the pillow which will protect them from fraying. Line the two pieces up.
  3. Sew three sides using a straight stitch.
  4. As you approach the corner, it's better to shorten the stitch length at the end of each side and stitch off the edge of the fabric. It makes a more durable corner--the bulk can be trimmed out of the corner, too, which makes a cleaner (pointy-er) corner. Press stop and wait until the machine stops. Make sure the needle is down and put the kickstand up. Rotate the piece and then put the kickstand down again and continue. Do the same thing to do the last side and press stop. Wait until the machine stops and you are done. Lift the presser foot to remove the work. Break the thread tails on the thread cutter, or clip with scissors.
  5. Press seams flat. Turn and press. Turn raw edges to the inside 1/4", and press.
  6. Stuff. Sew open side shut by stitching with straight stitch close to pressed edges.

(Note: you can use pins to hold things in place, but you need to remove the pins as you stitch. Never sew over pins. It breaks or bends needles, and can mess up the rotation/timing of the bobbin's oscillations.)

Troubleshooting

There are many different types of problems you can have while using a sewing machine, but here are a few basic problems.

  1. The needle thread breaks: Check the threading of the needle as it may not be threaded properly. It is also possible that the needle needs to be changed. Learn this skill from one of the sewing volunteers or aces so that you can perform a needle change when needed.
  2. The needle breaks: Make sure the needle is installed correctly and is tight. Verify you are using the correct pressure foot.
  3. Machine does not run smoothly: Verify the hook race and bobbin holder are free from lint.
  4. Clearing a thread jam: Because the rotation of the bobbin in the bobbin case is pretty sloppy, thread jams can happen fairly frequently. Use the screwdriver keys that came with the sewing machines to open the needle plate (a.k.a. the throat plate) and access the bobbin case.

Maintenance
