Editing Sewing

= Overview =

We have five mostly functional sewing machines:

Industrial style machines:
* Single Needle Lock Stitch (Juki DDL 227)
*Straight Stitch Walking Foot (Juki LU-563)
*Five-thread Overlock Serger (Juki MO-2416)

Home-style machines:
*Brother SE400 Combination Computerized Sewing and 4x4 Embroidery Machine
*130-Stitch Computerized Sewing and Quilting (Brother XR1355)

All sewing machines have QR codes on them that link to their entries on this page. Please use them.

We also have these sewing amenities:
* Giant ass table with cutting mat surface (50 inches x ? inches )

* Irons and Ironing board

* Big donation bins of extra thread and fabric you can use for projects

* lots of odds and ends

* 2 dress forms

- Full length mirror

= Tips =
* Please DO NOT unthread the sewing machines unless you must. (e.g. to remove a spool of thread, simply cut it close to the spool so that the next person can simply tie a knot with the next thread and pull it all the way through to the needle). This is most important for the serger. 

* Needles, bobbins, and other parts  are located in labeled drawers underneath the pegboard (PLEASE KEEP IT ORGANIZED). Also check the drawers attached to each sewing machine table.
** The closest place to get parts is at Apparel City, on Howard between 11th & 12th.  
** Needles may differ between machines and come in sizes (10, 11, 12, 14, 16, etc.). The higher numbers are heavier gauge needles suitable for thicker fabrics.
** Needles also come in different types, including (this is an abridged list; look to other sites for more complete lists):
***Jersey: Has a ball point, for knitted fabrics (including T-shirt fabric).
***“Universal”: Moderately sharp, for most woven fabrics. Denim needles are the same but more rigid, for tighter weaves of thick yarns (like denim or canvas).
***Microtex needles are the sharpest, for tight weaves of thin yarns, like microsuede or nylon.
***Leather needles have a tiny blade at the tip, for cutting holes in leather and vinyl. Don't use a leather needle for woven or knitted fabrics: The blade will cut the threads rather than squeezing between them, leaving holes that may start rips.
**Needles for the straight stitch machines must be inserted with the scarf facing right. Please check the respective manuals.

* If you've never operated a sewing machine before, ask some people at Noisebridge (Kyle or Ely). Sewing machines are not self-explanatory and this page does assume a certain amount of prior general knowledge.
**Read the manual and do some research online. 
**Printed manuals for the two Juki Machines and the Thompson are located in a grey binder on the bookshelf

*Use scraps for testing to determine thread tension and sewing speed.

==Winding a Bobbin==

=== Juki DDL-227 & Juki LU-563 ===
*To wind a bobbin, place the empty bobbin on the horizontal spindle to the right of the machine body (near the hand wheel).  Run a second thread through the upper holder, down to the tensioner at the back of the right side of the machine, in line with the spindle.  Thread the end through one of the holes in the bobbin side, from the inside to the outside.  Press the lever to push the spindle down in contact with the sewing machine belt.  While holding the thread end so it doesn't just whip out of the bobbin, press the pedal to run a couple of inches (if there were fabric in the machine).  Soon enough you can let go of the thread end as it will have been caught by windings on top of it.  If you are doing a lot of sewing, you can start a new bobbin before the current one is empty, and let it wind up as you sew.  When the bobbin is full, the lever will automatically snap out away from the belt and stop winding thread.

=== Most home sewing machines ===
The bobbin winder is usually on the top of the machine near the right corner (right being the side with the handwheel). It should look like a short spindle that can't be removed and sticks up about half an inch (the thickness of a bobbin) from a flat round surface.

Place a bobbin on the spindle, then:

* On some machines, the handwheel can be pulled out to switch from sewing to bobbin-winding. (Push it back in when you're done winding bobbins.)
* On the big Singer machine, the handwheel has a part that flips up to engage the bobbin-winder.
* On the Brother machines, the bobbin spindle can be slid between the left (sewing) and right (winding). In the latter position, a brake slightly intersects the bobbin and will stop it from getting over-wound.

Once the machine is in winding mode and is powered on, press the pedal slightly and make sure thread is going onto the bobbin properly. Once it's winding properly, floor the pedal until the bobbin is fully wound (some machines will stop the bobbin automatically; others may require you to pay attention).

Remember to switch the machine back to sewing mode when you're done winding bobbins!!!

== Repairing a Sewing Machine ==
* If a sewing machine is actually broken and non functional, as opposed to just you can't figure out how to make it work, please call Billy from Apparel City at 415-816-8645 (mobile) and schedule an appointment for him to come fix it.  
** He usually charges around $80 per hour, plus parts.  
** Email the [https://www.noisebridge.net/mailman/listinfo/sewing/|sewing list] and people will chip in to cover this.  If you can't manage this process, email the sewing list and find someone else who can.  Also, please put a note on the machine so people know what is going on with it.

== Straight Stitch Walking Foot (Juki LU-563) ==

*This is a high tension machine. You must press the knee lifter to pull thread through. This will release the tension.
**Conversely, DO NOT run into the knee lifter at all while sewing. This will release the tension and your stitches will be too loose.
*Pressing back or letting go of the pedal will engage the brake. Slightly depress the pedal to release the brake. You must do this to use the hand wheel

=== Overview ===
* Medium weight and heavy weight materials, leather and vinyl 
** Not for light-weight materials!
* Clutch Motor
** This machine is VERY fast
*Horizontal Bobbin
*Recommended thread size Tex-70 in the walking foot

== Five-thread Overlock Serger (Juki MO-2416) ==

'''Does Not Work''' as of 2019-03-09: The machine sews but does not cut well. This machine will be serviced professionally.

*Pulling fabric out of the machine may cause thread breaks. It is best to feed thread with the pedal when removing your workpiece.
*DO NOT UNTHREAD THE SERGER. It takes about 30 minutes and a lot of patience to thread this machine.  However, if you are an experience user of industrial sergers you will be able to thread this machine quickly.  Using tweezers helps.  Also, using the correct thread for the correct machine is essential.  Good Luck and happy sewing.

=== Overview ===
This machine is not made for knits.  It is made for wovens.  It is a five spool.  It has a clutch motor and this is the reason that it goes so very rapidly.  The overlock sews to prevent fray.  However, the machine make a chain stitch at the same time.  For example, if you were to look inside of your jeans, you can  observe these methods.  A chain stitch and overlock.  This type of machines is used for medium weight fabric.



*This machine has a knife placed to cut the fabric as you sew, and it *is possible* to cut your finger badly on this knife if you are not careful. BE CAREFUL. This machine also can go extremely, sometimes startlingly, fast.

== Singer Ultralock 14U64A serger ==

'''Works''' as of 2019-03-10

This is a four-thread overlock machine. It's evidently meant for knitted fabrics, as a silkscreened note on the upper-left of the front of the machine notes that it requires a Singer 2045 needle, which is a ball point.

The thread guides above the machine are on a pole that telescopes out. Make sure to raise it before using the machine; it works better that way.

*Parts list: http://parts.singerco.com/CPpartCharts/14U00/14U64A.pdf

= Scissors =

The sewing station includes a variety of scissors, including straight scissors/shears, a pair of pinking shears, and a couple other specialty scissors.

'''DO NOT USE FABRIC SCISSORS FOR ANYTHING THAT ISN'T FABRIC.''' Paper and other non-fabric things will rapidly dull blades to the point where we need to sharpen them again to use them on fabric.

There are some “paper only” (i.e., pre-ruined) scissors on the tools wall since we know people will look in the sewing section for scissors. There are also some “fabric only” (i.e., not yet ruined) scissors that should only ever be used for fabric.

Also related: There is a sharpening stone on the tools wall in the sewing station.

= Thread snips =

Thread snips are the small scissor-like tools used for cutting the thread sticking out of a work so you can remove the work from the machine.

Thread snips shouldn't be used to cut fabric—use the fabric shears (scissors) or rotary cutters for that. Neither should they be used on non-fabric things like paper or tape.

There are three pairs of thread snips hanging from the tools wall in the sewing section.

= Rotary cutters =

These look similar to pizza cutters but are '''NOT FOR FOOD USE''' (both because it trashes the blade and because the blades are not food-safe: new blades are coated in machine oil).

All of our rotary cutters are 45mm, except for one, which is 60mm but has no blade. It's unclear whether we'll keep that one, since we would need to keep 60mm blades in stock and that would mean figuring out where to keep them and what to use them for.

== How to use ==

Each rotary cutter has a cutting (blade extended) position and a safe (blade retracted) position. The Olfa ergonomic cutters will also spring back to retracted automatically, and can't be extended unless the safety button is pushed to the unlocked side.

Rotary cutters should be used on a cutting mat such as the one on the main sewing station table. Usually you want a straight cut, so you should use an acrylic ruler to guide the blade.

Rotary cutters are EXTREMELY sharp, so be careful. Please keep the cutter blade-side-up so it's less likely to come into accidental contact with the table or anything on it—if you can see the blade, you can avoid contact with it.

=== Safety tips ===

*Follow an acrylic ruler.
*Keep your body (including fingers) out of the path of the blade.
*Only use a sharp blade. Don't use a rotary cutter with a dull or trashed blade. Change out the blade if you have to.
*Don't force it to cut if it's not cutting.

== Maintenance ==

Rotary cutters are mostly pretty foolproof. As long as you don't cut yourself, your ruler, wood, another rotary cutter, a 1973 Oldsmobile, or anything else that isn't fabric, the blade should enjoy a good, long life.

But, every blade wears down eventually. Blade sharpeners exist but we don't currently have one.

If a blade can't be sharpened, there are new 45mm blades in the storage drawers along the wall.

=== Changing the blade ===

Here are the parts of a rotary cutter, from one side to the other:

*Hub/screw
*Rotary cutter
*Spring (in one of our cutters)
*Blade
*Plastic stabilizer disc
*Washer with a keyed hole
*Nut

No tools are needed.

#Remove the nut by hand, keeping your thumb on the hub/screw on the other side.
#Gently turn the cutter over and let the blade fall out onto your fingers, and the other parts onto the table.
#Sharpen or replace the blade.
#Put the blade onto the screw.
#Put the screw (with blade) into the cutter, and put the spring (on the cutter that has one), disc, washer, and nut onto the other side.

= Parts Needed =

Some of the parts (especially pedals and/or cords) for the sewing machines have, shall we say, installed a walking foot. Here's what we're currently missing:

* The two Brothers and possibly the Kenmore share one working pedal. There's a second pedal but its connector has been ground down and it no longer works.
**It looks like a 3.5mm mono plug, so it may be possible for an electronics hacker to fix this by swapping out with an undamaged plug.
* The two Brothers share one bobbin case cover. (Fortunately, it is possible—if somewhat risky—to sew without a bobbin case cover.)
* The Kenmore also needs a 6V 1.2A negative-outer power supply. We have a wall-wart in the wall-warts bin that's *almost* right, except it's 1.5A, and the Kenmore just runs full-bore with that supply plugged in, regardless of any pedal that may or may not be plugged in.
* The White E-6354 is missing a power cord. (This one may be a challenge…)
