Need Help With Presser Foot Timing

Need help with vibrating presser foot

Hi everyone! I was hoping that someone could help me with the proper adjustment of my presser foot.

I have a Consew 226 with reverse (I think this is called a 226 R 1 ) that I bought about 2 weeks ago and with the help of Bob at Toledo Industrial Sewing Machines LTD in Toledo, Ohio over the phone we have fixed most of the problems that the machine had. The problem now is that it is skipping stitches. I believe the timing with the hook and needle is right, but I could be wrong.

I’m thinking that the problem is in the adjustment of the presser foot. The only thing I have to go by to try and adjust it is a users manual I downloaded from the internet and it is not very informative and the photograph are not very good ether.

The manual says how to set the foot for the timing by loosening two screws on the back side but I can not find these screws so I’m thinking maybe my machine is an earlier are later model year.

The manual is also confusing in that it says to ( “loosen the two screws U, fig. 6” ) and adjust the rotating position of the cam (“ V, fig. 6” ) faster or slower as may be desired. And tighten ” the screw”. So I don’t know if I’m looking for one screw or two.

I also don’t really know what they mean by “set the lift of the alternating presser feet equal”

Any help would be very helpful to me, like I said I’ve had this machine for two weeks now and have not been able to use it. Sure would like to make something with it.

Thanks in advance

Mick

Hi Mick,

Seem like the hook is out of timing, if it is skipping stitches. I do not know your type of machine, but the height of the alternating pressers is set for the thickness of material you are going to sew. I think your problem is related to the hook timing. The vibrating presser should hold the material down when the other presser and the needle moves forward. Are you sure you got the hook timing right?

Cefalo is an auto trimmer who has some informative videos about adjusting sewing machines on youtube. The machine he is adjusting has only drop feed, but it will help you understand the principals on hook timing. (He also has other very good videos about automotive upholstery). http://www.youtube.com/user/Cechaflo#p/u/3/lHhlHbUYwV8

Try to find a service manual for your machine, there is so many bad copies of manuals out there with wrong information. I believe your machine is a very common type in the US, maybe some of our member have a service manual they will share with you.

If I did this right you should be able to download the manual.

Mickt,

If your machine is skipping stitches, you really should be looking at the hook timing, needle bar height, and distance from hook to needle. That's much more likely the issue.

THAT said, you are talking about presser foot adjustments; one is to time the vibrating presser foot and needle in relation to the feed timing. On the 226R if I'm not mistaken, this is 'fixed' with a screw falling onto a a slot on the top shaft. May be wrong on that, but again not likely the issue here. This adjustment is on the two flat head screws that ride on the eccentric cam off off of the top shaft that 'drives' the walking foot shaft on the back of the arm, for lack of better description. The other adjustment you are referring to is the screw (some have a flat screw head in conjunction with a 10mm hex socket head) off the crank that adjusts the lift of the feet, that should be equal lift, favoring the outside if you have to use your judgment and not exact tools. This way both inside and outside feet rise equal. This is also found on the rock shaft bar that stick out the back of the machine. Again, I very much doubt either of these setting are what are making your Consew 226R skip stitches, and I would inspect a good number of things including worn or broken parts before even checking these settings on the machine, if it were skipping stitches.

Hi Gregg,

Thanks for replying!

It appears from your's, Trox's and Busted's replies that the problem is with the timing. My thought on the presser foot was maybe the materal was not feeding right.

Ok, so can anyone tell me how to time it in simple words ( I under stand this may not be simple) and a step by step way to time it? I'm up for trying if I could understand how. Some times the names of the parts are confusing so that makes working on it a litte harder not knowing just what they do and me not wanting to mess it up any more then it might be.

When I look at the neddle and hook, it looks to me that when the needle is all the way down, the needle starts to rise just a little bit maybe a 16/th of an inch and at that time the tip of the hook is at about the midde of the needle and just above the needle thread and is picking up the bobbin thread.

Questions about timing:

#1

It's my understanding that the needle is to be all the way down and then bought up about 3/16 of an inch before starting. Is this right or wrong?

If i bring my needle up that high then the hook will be past the needle. The other day while timing it we moved the hook back but I can't remember how I did it. I remember taking one or two screws loose and tapping something?

#2

At what point should the hook make contact with the needle?

#3

How close should the hook be to the needle?

Should this be done with a feeler gauge?

#4

In my case should I use the needle bar to lower the needle all the way down, rase it the 3/16th, place the hook next to the needle, loosen the needle bar and lower it to the position it at the scarf area and retighten the needle bar? Or something else. In any case it appears that the hook needs to be ajusted back I think.

Bob from Toledo sewing machines LTD in Toledo has been a big help, helping me walk through the problems with the machine and I thought I had the timing right but may not have got it just right and it may need some small adjustment to keep it from skipping.

Thanks in advance for any help

Hi Busted,

Yep the link worked this time. However it is the same users manual that I have and the only one I have been able to find on the internet. I have found 4 or 5 different sites for a 226 manual but they are all the same one.

I would think that there is a repair manual out there somewhere, as service repair people had to work and repair these machines at some point. You would think that Consew would have these in a dusty back room on a shelf.

Thanks again for the help and your time

Mick,

The needle bar is supposed to go up 3/32" then the point of the hook is sup[posed to be @ the needle,you set this first then make sure the eye of the needle is approx 1/8" below the point of the hook as it crosses the needle,the hook point needs to be as close as it can be w/o hitting.

Bob

To change the hook timing you loosen the screw on the big gear & move it left or right as needed.

Thanks Bob,

Took me a few trys but worked out fine, not skipping now. I think it just took the curage to dig into it.

Thanks Bob,

These links are great just what I was looking for. Like I said on the phone today I am trying to put together a pamplet on just the singer 111 W 155 since a lot of machines are clones of it. I'm hoping to make it advalable to others here on this site thinking it would be useful when working on thier own machines.

Thanks again

I would like to continue the thread of timing the vibrator presser foot. Same machine, Consew 226. Mine is completely out of whack compared to the owners manual. When the needle is in the lowest position, the vibrating presser foot is in the HIGHEST position, so they are not helping the machine to stitch. So when I stitch slowly I get a decent stitch, but when I speed up the thread is gobbed on the bottom. I am also frequently getting thread wrapped around the hook.

I found where the eccentric cam is, loosened the two set screws, but I can't get the cam to turn. Am I being too gentle? I even disengaged the cam arm at the big thumb screw, but that didn't change things. What am I missing?

Thanks in advance.

Hi all. On all of these types of machines, ( Consew 225, 226 255, Juki 562, 563, Singer 111W, and so on), the belt timing is critical. On the bottom of these machines there are timing marks. Bob at Toledo has the pictures. This timing adjustment is the FIRST thing that you check. If the belt timing is off, then it doesn't matter about any other timing, (hook timing or feed timing), it will not sew correctly. Please make sure the the belt timing is correct before you proceed with any other adjustments. Steve
