When should I replace my sewing machine needle?
Amazing Designs recommends inserting a new needle at the start of every project, or after about eight hours of sewing. Also, be sure to change your needle whenever it becomes bent, dull or develops a burr. Damaged or worn needles result in: Broken or shredded threads.
What happens if you use the wrong bobbin?
The short answer is YES! Filling a sewing machine bobbin too tightly can make a plastic bobbin bulge or stretch the thread if you are using a metal bobbin. This may be hard to see but can cause all kinds of problems. Plastic bobbins can become compressed in the center causing the bobbin to distort.
How much does it cost to fix the timing on a sewing machine?
To save yourself some money on buying the service manual you can take your machine to a qualified repairman and he should be able to repair the timing for about $50 to $80. That fee probably will change depending on where you live and the type of machine you need to have repaired.
How do I know if my sewing machine timing is off?
If your hook tip is passing through or below the needle eye, then the timing of the sewing machine is off. On the other hand, if the hook tip is passing above the needle eye, but extends past the needle more than a couple of millimeters when the needle eye meets the radius of the hook, then the timing is also off.
