Where is the needle plate setting knob on Janome overlocker 134D so I can change from roll to serge. I have successfully threaded the machine I just need to find where the setting is to change from roll to serge on the needle plate please.

No you do not need the cutting blade to serge but you shouldn't have to remove the blade it you should be able to push the knob at base of blade inward or pull it outward to turn blade downward out of the way.

TUTORIAL - How to do a rolled hem on a serger - StitchCraft

http://stitchcraftonline.com/blog/?p=42 - 71k - similar pages Aug 5, 2009 ... One of my favorite uses for my serger is to do rolled hems. A rolled hem is were the machine folds the fabric under a tiny bit and then stitches it.

not exactly your serger model but technique will be very similar for rolled hem.

You need to set up a three thread overlock with the right hand needle, (take left needle out), and change the thread finger in the throat. Sometimes a switch to do this and sometimes it is a little piece on the foot that you change with a screwdriver.

Also, this solution http://www.fixya.com/support/t9280656-thread_janome_204d_serger is basic threading on 204D, it should be very similar to your model.

I have looked for a free download instruction manual for your machine without success. But you should be able to buy one from Janome or another of the online sewing sites like www.sewusa.com or www.sewingpartsonline.com.

]ve a manual you can somtimes find them on the Janome websit

Is this on a serger?

Rolled hemming on a serger is usually achieved by doing the following: thread up for three thread overlock using right hand needle. Move blade to the right to trim fabric wider (so it rolls inside the seam). Put woolly overlock thread through top looper (this gives a smooth finish to the rolled hem). Loosen off top looper and tighten up bottom looper so the bottom looper is up tight against the needle thread on the underside. Test serge to get the stitch right, then turn the stitch length down to 0.5 to close it up tight (this uses loads of thread so I usually get everything else right first, then make this final adjustment). On my Bernette 334D tensions are R-Needle - 5, Top looper 7-8 and bottom looper is 3-4. Stitch length 0.5, differential zero.

And usually you flick a small lever or change a little finger on the foot or plate where the stitch forms, there is some variation here between models. Early Elna L4 and L5 locks you had a little finger you changed with a screwdriver on the pressure foot. Bernette has a little slide mechanicism near the blade that you flick forward to engage.

Hope this is of assistance to you - I went for a 2 hour lesson on my serger when I bought it and then came home and repeated all the techniques shown and then made notes and stapled all the stitch samples into a notebook so I could remember how I did it.

Also there are some great books on Serging, Nancy Zieman is one name that springs to mind. Or try You-Tube, she has some videos up there too showing different techniques.

Typically, set all your tension knobs to 4

my overlocker is a janome and i use generic overlocker needles; these are all rounded, not flat on one side. i hope this helps

Stitch length should be set between 1 to 2.

• the factory default settings are 4,4,4,4 and M
• Change the needles
• use a can of air spray ( compressed air can sold in computer stores) to ensure there is no fabric or dust under the needle plate

make sure the needle is pushed in properly.

Set you differential at 1.0 and your loopers at about 3-4 the needle thread tensions are usually around 5 to 6.
 I would also suggest that you place four different color threads on machine to make it easier to adjust all. Now if you are using only 3 threads the same applies.
