Preparing Your Sewing Machine for Threading
Before you begin threading, proper machine setup is essential. This initial stage lays the groundwork for a frustration-free threading process.
Ensuring the Needle is Correctly Inserted
The first step in preparing your machine is to correctly insert the needle. A properly seated needle is vital for good stitch formation.
- Remove the Old Needle: Always remove any existing needle.
- Select the Right Needle: Use a needle appropriate for your fabric type. A universal needle is a good starting point for most fabrics.
- Insert the Needle:
- Turn the handwheel towards you (counter-clockwise) until the needle is at its highest point.
- Loosen the needle clamp screw.
- Insert the new needle into the clamp, with the flat side of the needle shank facing away from you.
- Push the needle up as far as it will go into the clamp.
- Tighten the needle clamp screw securely. Ensure the needle is straight and firmly held.
Checking the Presser Foot Position
The presser foot needs to be in the correct position for threading. This ensures the thread can pass correctly through the presser foot mechanism.
- Lower the Presser Foot: Gently lower the presser foot onto the fabric plate. This engages the presser foot bar and allows the thread to pass through the tension discs correctly.
- Ensure it is Firmly Down: Make sure the presser foot is fully down. If it’s slightly raised, the upper thread tension will not engage properly, leading to skipped stitches or no stitches at all.
Basic Machine Setup Checklist
A quick check of these basics will prevent many common threading problems.
- Power Off: Ensure the machine is turned off or unplugged.
- Cleanliness: A clean machine sews better. Remove any lint or dust from around the needle, bobbin area, and feed dogs.
- Needle Plate: Ensure the needle plate is clean and correctly positioned.
- Handwheel Direction: Always turn the handwheel towards you (counter-clockwise) when adjusting needle position or completing stitches manually. This is a universal rule for most sewing machines.
Winding a Bobbin
A correctly wound bobbin is as crucial as the upper thread for successful sewing. Many older machines have a separate bobbin winder.
The Bobbin Winding Process
- Place the Bobbin: Put a bobbin onto the bobbin winder spindle. Some machines have a small clip to hold it in place.
- Thread the Winder:
- Find the thread guide for the bobbin winder. This is usually a small hook or eye near the spindle.
- Take the end of your thread and pass it through the winder thread guide.
- Bring the thread around the back of the bobbin, and then thread it through one of the small holes in the bobbin.
- Hold the thread tail securely.
- Engage the Winder:
- Push the bobbin winder spindle to the side, engaging it with the machine’s drive mechanism. This often disengages the main needle.
- You might need to push the spindle until it clicks or locks into place.
- Start Winding:
- Hold the thread tail firmly for the first few turns.
- Gently turn the handwheel towards you to start the bobbin winder. The machine will begin winding the thread onto the bobbin.
- Once you have a few wraps, trim the thread tail close to the bobbin.
- Even Winding: Allow the machine to wind the bobbin evenly. Many older machines have a small guide that moves back and forth to ensure even distribution.
- Stop Winding: Stop winding when the bobbin is full, or when the winding speed slows down significantly due to the bobbin filling up. Some machines have an automatic stop.
- Disengage and Trim: Push the bobbin winder spindle back to its original position to disengage it. Cut the thread to release the wound bobbin.
Troubleshooting Bobbin Winding Issues
- Uneven Winding: Check the thread guide on the winder and ensure the thread is passing through it. Make sure the bobbin is seated correctly on the spindle.
- Thread Snapping: Ensure you are using the correct thread and that the bobbin winding tension isn’t too tight. Check the bobbin itself for any nicks or rough edges.
- Bobbin Not Winding: Verify that the bobbin winder spindle is properly engaged and that the machine’s main drive is disengaged (usually by pushing the spindle).
Threading the Upper Thread
The upper thread path is the most complex part of threading an older sewing machine. Following the numbered guides on the machine itself is the best approach.
Following the Threading Path
Most older sewing machines have a clearly marked threading path, usually indicated by numbers or arrows on the machine’s casing. Always start with the presser foot up.
- Spool Pin: Place your spool of thread on the spool pin. Ensure the spool is oriented correctly; often, the thread should unwind from the front or top of the spool.
- Thread Guide at the Top: Take the thread and bring it up to the first thread guide, usually a small hook or eye near the spool pin.
- Thread Up to the Tension Discs:
- Guide the thread downwards and then back up, ensuring it passes between the upper thread tension discs. This is a critical step for upper thread tension control.
- Make sure the thread is seated firmly in the groove of the tension discs.
- Thread Take-Up Lever:
- Bring the thread downwards again and loop it around the thread take-up lever.
- Ensure the thread passes through the eye of the take-up lever from the outside to the inside, or as indicated by your machine’s guides. This lever’s movement is crucial for stitch formation.
- Second Thread Guide: Guide the thread downwards to the next thread guide, usually located below the take-up lever.
- Needle Clamp Thread Guide: Follow the path to the final thread guide, typically located on the needle clamp itself, just above the needle eye.
- Threading the Needle:
- Lower the presser foot.
- Thread the needle from front to back, or side to side, depending on your machine’s design. Many older machines prefer threading from front to back.
- Leave a tail of about 4-6 inches.
Essential Checks for the Upper Thread
- Presser Foot Up: Always ensure the presser foot is up when threading the tension discs and take-up lever. This opens the discs, allowing the thread to seat properly.
- Thread in Tension Discs: Double-check that the thread is firmly between the tension discs. If it slips out, you won’t have proper upper thread tension.
- Take-Up Lever Engagement: Confirm the thread is correctly threaded through the eye of the take-up lever.
Inserting and Threading the Bobbin
Once the upper thread is in place, it’s time to insert the bobbin and bring up the lower thread. The bobbin case mechanism varies between machines, but the principle is the same.
Inserting the Bobbin
- Locate the Bobbin Case: Open the bobbin cover (either at the front or bottom of the machine). Locate the bobbin case.
- Place the Bobbin: Hold the wound bobbin with the thread unwinding counter-clockwise. Insert it into the bobbin case.
- Thread the Bobbin Case:
- Find the small slot in the bobbin case.
- Guide the thread from the bobbin through this slot.
- Pull the thread under a small metal finger or spring within the bobbin case. This provides the lower thread tension.
- Leave a tail of about 4-6 inches.
Bringing Up the Bobbin Thread
- Hold the Upper Thread: With one hand, gently hold the tail of the upper thread.
- Turn the Handwheel: With your other hand, turn the handwheel towards you (counter-clockwise). This action will pull the needle down, catch the bobbin thread, and bring the bobbin thread loop up through the needle plate.
- Retrieve the Bobbin Thread: Use your fingers or tweezers to pull the bobbin thread loop completely through the needle plate. You should now have two thread tails hanging from the needle area.
- Place Threads: Place both the upper thread tail and the bobbin thread tail under the presser foot and towards the back of the machine.
Adjusting Lower Thread Tension
The lower thread tension is primarily controlled by a small screw on the bobbin case.
- If Bobbin Thread is Too Tight: The screw on the bobbin case needs to be loosened slightly (turn it counter-clockwise).
- If Bobbin Thread is Too Loose: The screw needs to be tightened slightly (turn it clockwise).
A good starting point is to have the bobbin case hang from the thread tail when you hold it up, and the bobbin should unwind with a slight resistance.
Fine-Tuning for Perfect Stitch Formation
Once threaded, a few adjustments will ensure your machine is ready to sew beautifully.
Adjusting Upper Thread Tension
The upper thread tension is controlled by the tension dial on the front of the machine.
- Higher Numbers = Tighter Tension: Most machines have numbers on the dial. Higher numbers mean more tension (thread is pulled tighter).
- Lower Numbers = Looser Tension: Lower numbers mean less tension (thread is looser).
The goal is to have the upper and lower threads meet evenly in the middle of the fabric layers.
- Too Tight Upper Thread: If the upper thread is breaking or digging into the fabric, or if you see loops of the lower thread on the top of the fabric, the upper tension is too high. Turn the dial to a lower number.
- Too Loose Upper Thread: If you see loops of the upper thread on the underside of the fabric, the upper tension is too low. Turn the dial to a higher number.
Testing Your Stitch Formation
Before sewing your project, always test your stitch on a scrap piece of the same fabric.
- Place Fabric: Put a piece of fabric under the presser foot.
- Lower Presser Foot: Lower the presser foot.
- Sew a Few Stitches: Sew a short seam, keeping the fabric steady.
- Examine the Stitch:
- Balanced Stitch: The stitches should look even on both sides, with no loops or puckering.
- Upper Thread Loops on Bottom: Upper tension too loose. Increase upper tension.
- Lower Thread Loops on Top: Upper tension too tight. Decrease upper tension.
- Fabric Puckering: Tension may be too high overall, or you might need a different needle or presser foot pressure.
Threading Multiple Colors
If you’re using different colored threads for the upper and lower thread, the tension balance becomes even more visually apparent.
- Ideal Scenario: The colors should not show through on the opposite side of the fabric.
- If Top Thread Shows on Bottom: Increase upper tension or decrease lower tension.
- If Bottom Thread Shows on Top: Decrease upper tension or increase lower tension.
Common Troubleshooting Scenarios
Even with careful threading, issues can arise. Here are some common problems and their solutions.
Thread Breaking
- Upper Thread Breaking:
- Check needle insertion (is it straight and fully seated?).
- Is the needle blunt or bent? Replace it.
- Is the thread snagged on the spool or winding around the spool cap?
- Is the upper thread tension too high?
- Is the thread passing correctly through the tension discs and take-up lever?
- Is the presser foot down when sewing?
- Bobbin Thread Breaking:
- Is the bobbin wound evenly?
- Is the thread catching on the bobbin casing or the bobbin itself?
- Is the bobbin case tension too tight?
Skipped Stitches
- Needle Issue: The most common cause. Ensure the needle is the correct type for your fabric, sharp, and not bent. Re-seat the needle.
- Incorrect Needle Insertion: Double-check the flat side of the needle shank.
- Thread Path: Make sure the thread is correctly threaded through all guides, especially the tension discs and take-up lever.
- Presser Foot: Ensure the presser foot is fully down.
- Timing Issue: If all else fails, the machine might have a timing issue (the needle and bobbin hook are out of sync), which requires a service technician.
Machine Not Stitching
- Threading Errors: Re-thread the entire machine, paying close attention to the upper thread path and bobbin insertion.
- Presser Foot: Is the presser foot up? The machine won’t stitch with the presser foot up.
- Bobbin Winder Engaged: Ensure the bobbin winder is disengaged and the machine is set to sew with the needle.
- Needle: Is the needle inserted correctly and securely?
Maintenance Tips for Older Machines
Regular maintenance ensures your older sewing machine continues to thread and sew reliably.
Cleaning and Oiling
- Remove Lint: Regularly clean lint from around the needle, feed dogs, bobbin area, and tension discs. A small brush and a vacuum cleaner are helpful.
- Oiling: Consult your machine’s manual (if available) or a general sewing machine manual for oiling points. Most older machines benefit from a drop of sewing machine oil in designated spots periodically. Oiling the bobbin race area is particularly important.
Needle Replacement Schedule
- Change Frequently: Needles are consumables. Change your needle every 8-10 sewing hours or after completing a large project. A dull needle can cause skipped stitches and fabric damage.
Frequently Asked Questions (FAQ)
Q: What is the most critical step in threading an older sewing machine?
A: The most critical step is ensuring the thread is properly seated between the upper thread tension discs. If the thread isn’t in the discs, you won’t have any upper thread tension, and stitching will fail.
Q: Can I use any type of thread on my older machine?
A: While most modern all-purpose polyester threads are suitable, very thick or very fine threads might require adjustments or different needle sizes. It’s best to start with standard 100% polyester or cotton thread.
Q: My machine is making a lot of noise when I sew. What could it be?
A: Noise often indicates a need for cleaning and oiling. Lint buildup and lack of lubrication can cause friction and noise. Ensure the bobbin area is clean and that all moving parts are properly oiled.
Q: Why does my thread keep breaking?
A: Thread breaking is usually due to a needle issue (dull, bent, or incorrectly inserted), incorrect threading path (especially around the tension discs), or the upper thread tension being too high.
Q: Is manual threading really necessary for older machines?
A: Yes, older machines do not have automatic threaders, so manual threading is the only way to get them ready to sew.
