Ed,
In answer to your question - getting too many fraying thread breaks thinking
it's a bur on the needle as the needle does not feel as "sharp" as a new
one. Can't tell with a magnifier if it actually has one. So it's more of
hunch. I think I need to get a microscope :) (I have progressive lenses
and close up stuff is not good) Any way to check for burs other than sight.
Needle plate seems to be free of burrs
Presser foot all the way down
Needle rotation correct
Needle pushed all the way up
Fabric taut
Thread frays - pretty much every needle
One broken needle in the life of the machine about a year ago
No caught garments
Take up lever cam lubricated in awhile but will try
No hoops hit
My amaya is 2.5 years old, but with very limited use. (z run time
286:07:42) I'm sewing on sample material - broadcloth with 2 oz cutaway
and/or 2 layers of 2 oz cutaway. In a perfect world, sewing on this type of
material, a design free of defects, using only 1 needle, how long (# of
stitches) should this needle last. Titanium vs. non?
Off to grease the take up lever.
Thanks for your help,
Terri

Hey Terri,
Traditionally, needle burs are generated in one of two ways: either the
needle is being deflected ( by something) and then rubbing against something
hard like the needle plate, presser foot, edge of hoop, and even things like
zippers on garments. ...Or something is hitting the needle in the process
of making a stitch - like the machine's very own rotary hook.
Chances of the first are slim however the latter is more likely. During a
normal stitch, the spacing between the needle and the spinning rotary hook
is only about the thickness of a single thread. If the needle is encouraged
to bend towards the rear of the machine or the hook position is set a little
too forward, then the rotary hook strikes the back of the needle and burrs
can happen.
Also know that a needle installed backwards is an excellent way to get burrs
on your needle. Because the scarf of the needle is now in the wrong place.
I'm assuming you are feeling burrs on your needles with your finger or can
see them with a magnifying glass????
If this is not the case, and you are guessing that burrs are your problem
causing fraying and thread breaks, then we might want to consider some other
issues.
Let's look at these possibilities a little closer:
- is your presser foot position all the way down?
- is your needle rotation correct.. the groove down the shaft of the needle
facing forward?
- is your needle pushed all the way up into the needle clamp before
tightening?
- is the fabric in the hoop taught and not loose?
- do you get these thread frays and breaks on every needle?
- have you broken any needles lately? if so how many?
- have you caught any garments, or other items, in the rotary hook recently?
- have you lubricated your take up lever cam on a regular basis? (How old
is your machine?)
- have you hit a hoop recently?
These are just a few questions I would ask myself if I were going to
troubleshoot your machine.
After that it's a process of elimination. Let me know how you would answer
these questions and I'll try to offer up some possibilities.

Subject: [amayausers] Needle bur ??
I'm looking for some possible causes of needle burs? I believe I'm getting
needle burs, at least it feels that way. This happens with needles that
have less than 1000 stitches. A brand new out of the box titanium needle is
put in (feels ok), after sewing lettering on knit (bookman, .3 ", centerwalk
underlay, density 5 pt., stitch length 20 pt) using 2 oz. cutaway backing
and solvy topping, after about 500 stitches get fraying thread breaks, and
the needles feels like it was a bur. Tried using autoactifeed and it sews
at MT of 1. Use manual MT of 2-3. Any thoughts at what might be causing
this?
