Just Zigzaging Along

This week I was asked what the best zigzag sewing machine was.

As with most questions, it's not as easy as just spouting out an answer, so here are some guidelines on choosing the best Zigzag machine for you.

Zigzag machines (as opposed to straight stitch machines) come in three styles.
We'll name these categories by their bobbin designations:  Class 15,  Class 15 Front Load, and Drop-In.

Class 15
Picture
Originally, most zigzag sewing machines were in the Class 15 style.

The Class 15 bobbin case is located at the end of the sewing machine.

This style functions very well, due to the the timing being pinned (rather than screwed) in place.
In 27 years I have never had to reset the timing on a Class 15 machine.
In addition, the entire bobbin case moves with the needle as it zigzags, making sure each stitch is consistent.
Picture
The difficulty with this style, however, is removing and replacing the bobbin through the small opening.

Class 15 Front Load
Picture
To fix this problem, Class 15 Front Load machines were created.
Picture
Using a snap-in bobbin case at the front of the machine, is easier to load.
Unlike the Class 15, the bobbin case is static, meaning that the stitch is more likely to lose timing.
Picture
Drop-In
Picture
Drop-In sewing machines are the most commonly made today.

Quick and easy to load, the bobbin is placed horizontal in the bobbin case.
Picture
Just like Class 15 Front Loads however, the bobbin case remains static during zigzaging.
This may result in skipped stitches where only one side  --Left or Right -- is actually sewn.
The final decision comes down to how much effort you want to spend replacing the bobbin:
  • Class 15s are the most precise, stitch-wise, but are also the most difficult to load.
  • Class 15 Front Loads and Drop-Ins easier to load, but will also occasionally lose timing during a project.
Have any feedback or questions?  Please leave a comment, we'd love to hear from you!

When Things Go Screw

When Things Go Screwy
Several times a month a customer comes in missing a tension screw. The story goes, " I was just loosening the screw and BONG!! it was gone." The sad part is that the screw did not need to be messed with in the first place. Usually when the tensions in a sewing machine are not working, the problem is with the top tension not the bottom. This is hard to believe when the thread is all balled up under the machine.  If it happens to you, here is a hint to help solve the problem of the missing screw.

Put a magnet in a plastic bag and slide it around on the floor and around table and chair legs. (Screws love to hide around these places.) You might just find the screw to be replaced into the bobbin case.
