This small dowel holds the thread. Some machines come with several spool pins for various types of thread spools and for decorative or twin-needle sewing. Spool pins can be horizontal or vertical, but horizontal ones provide smoother thread feed.
Why do spool pins make locks harder to pick than regular pins? Because the narrow waist of the pin will get stuck at the shear line binding the lock so it can't turn any further. you're almost there once the spool pin gets bound. You can feel this happening because the lock plug will rotate slightly when it happens.
A spool cap holds the spool of thread in place to give your machine an even feed of thread. Without this component, your spool will jump around and may come completely off of your machine. The spool cap is an important part of a sewing machine and many machines will not function properly without this piece.

A spool never unlocks, they all handle the same as a welded diff. Both wheels turn at exactly the same speed all the time. A locker unlocks with a certain amount of turning force if it's an auto locker, or when selected if it's some kind of manual locker.
When an incorrect key is inserted into the lock, the key pins (red) and driver pins (blue) do not align with the shear line; therefore, it does not allow the plug (yellow) to rotate.
The spool thread comes from the top of the machine and goes through the upper thread guide, while the bobbin thread is under the needle and goes through the bobbin thread guide. Many novice sewists don't realize that there are two pieces of thread that go into sewing, the spool thread and the bobbin thread.
All it takes is practice. There are many advantages to sewing without pins. You won't break machine needles sewing over them, your overlock cutter will never dull, and you won't step on them when they inevitably fall to the floor. Here, Carol shares some exercises to build your skills.
Glass-head pins
Look for labels that say “fine,” “extra-fine,” or “silk” pins. They are easy to see and to pick up, and the heads don't melt when touched with an iron. They come with various colored heads. For most garment-construction tasks these pins are well-suited.
A backstitch is one of the strongest hand sewing stitches. The backstitch gets its name because the needle goes into the fabric behind the previous stitch. On the contrary, with a running stitch, the needle simply passes through the fabric an even distance in front of the previous stitch.
