Janome Mylock 634D Serger Review

If you think this serger would be a good fit for you’re sewing projects we will go through the features, and you can judge for yourself.

Stitches

The machine will do rolled hemming, picot edging, narrow hemming, decorative overedging, pin tucking, and you can find in the manual a chart recommending the thread, needle, stitch length, and differential feed for the type of fabric you are sewing.

The maximum stitch length is 5 mm and can be easily be adjusted with a dial on the right end of the machine, and the stitch width is 7 mm maximum and also can be adjusted with a dial under the sewing end side cover.

This machine is able to sew up to 1300 stitches per minute, and the speed is controlled by the foot pedal which you might want to practice with first before sewing, and have the presser foot up when practicing at this.

Also when stitching there are guide lines on the looper cover that shows the distance from the needles.

Threading The Janome Mylock 634D Serger

This serger has the color coded thread guides, and the lower looper is self threading plus a threading chart is on the body of the Machine under the looper cover.

It is recommended to thread the lower looper first then upper looper, then needle on the right followed by the left needle.

Also when threading raise the presser foot which makes it easier to insert the thread between the tension disc, and with a little practice threading this serger will take no time at all.

Once you have the machine all threaded and set up we recommend trying out the machine on some spare fabrics first.

Presser Feet

There is a Standard serger foot that comes with this machine, and you can buy optional feet such as the blind stitch foot, taping foot, cording foot, and piping foot.

The feet are easy to change by pressing the lever behind the foot and it drops off, then snap a new one in place by lowering the foot holder onto it.

There is a foot pressure adjusting screw on top of the machine which for normal sewing it is not necessary to be adjusted, but if needed can be adjusted for heavy or light fabrics.

Feed Dogs

The differential feed for the feed dogs can be adjusted by a dial on the right end of the machine, so that if the fabric you’re sewing is stretched, just adjust dial counter clockwise, and if fabric is shrinking, turn dial clockwise.

Knives

The knives can be adjusted for width with a knob under the end cover, and the upper knife can also be set out of the way if you prefer not to use it.

Buttons For Operating and Adjustments

First on the list are the 4 tension dials, upper and lower loopers and right and left hand needles dials.

Under the end side cover is the cutting width adjustment dial, and the upper knife release knob, plus the needle plate setting knob.

Presser foot adjustment is on the top of the machine.

Stitch length, and differential dials are on the right end of the machine, above the balance wheel.

Lighting

This machine has a 15 watts light bulb just above the sewing area for illumination, and if it ever needs to be replaced just remove the face plate to take it out.

  1. Great review Alex,

    I’ve heard about sewin machines but never knew about the overlocker, simply amazing how easy it makes sewing look! I wouldn’t mind pricey if it can last for years, my grandmother has this very old traditional sewing machine which uses pedals and it’s still functioning. 

    Janome Mylock would definitely be a great Christmas gift for her, do you think they do international shipping since it’s on Amazon?

    • Hi Riaz,

      As Amazon works in many countries you can check if there is one in your country and you can take a look to see if Janome has a dealer in your country, if not, you can visit the sewing machine dealer in your city and ask him for this serger.
