Still having same problem please help

Did the sewing mechanic get it sewing right?

Does it sew well with 92 weight thread too and bottom?  

Is that white thread the same stuff you were having trouble with?

Sometimes when troubleshooting a machine problem, the best thing I have done is ditch problem thread.  Sun Guard thread never worked for me at all, for instance.  I tossed it in the trash and my problem went away.

I agree. I would:

i) try a new spool of top thread and if you change the size of the top thread change the needle size according.

ii) reload bobbin thread with fresh thread as if it has been wound for more then a couple of days it may have developed a "coil memory". This may or may not be a problem it will depend on a) color (black is the worst), size of spool it comes off (8 oz or 1lb spool), winding tension and whether it is a brand name thread (like A&E and others) or a poor quality clone thread from China.

If you are using 8 oz spools of thread change to 1lb and use a brand name thread. The 8 oz spools, in my experience, are the worst for developing " coil memory " and " spring back " tension problems. The difference in quality and consistency of a brand name thread to that of the cheap China thread can be like the difference between night and day.

Selecting good quality thread and needles are just as important as selecting a machine. Good machine with poor needles or thread will give you either problems or a poorer quality finished product.

Yes the cost will be greater for a brand name thread but when you have to throw out thread because of poor quality / consistency what did you really save?

Any chance of posting a photo of how you got your top thread setup?

It also may come down to the machine may not being able to handle V138 thread in what you are sewing because of needle to hook clearance.

I don't know if you have a manual for your machine so I found a link to the consew 225 ( www.consew.com/Files/112347/InstructionManuals/225.pdf  ) which maybe of some help. Also there is a repair manual that you can download from ( http://prod2.wikifab.org/cgi/viewcontent.php?article=consew.repair.manual&context=libpubs  ) but you have to signup for an account.

I stuck with thread cause machine guy said the timing issue was causing pinching the thread and that was causing thread issue but I’ll try something different and see. I know uwe has a thread with a 225 using 207 top and bottom and looking great. I was trying to adjust one thing at a time since it seems that every change triggers a domino effect of other things. Also I was trying to use different color top from bottom so I could tell which side wasn’t acting right. 
 

I’ll try 92 top and bottom and different needle and see

Which size needle with the 92 thread?

[kgg]

I would try either a 22 or 23.

I use a #19 or #20 needle with #92 thread, top and bottom. The #19 gives a tighter lay in soft to medium temper materials. The #20 lets me sew through double-sided tape without gumming up the eye of the needle. I recommend titanium coated needles to help sew difficult and dry materials.

If you are having trouble pulling the knots up from the bottom and are using the correct needle size, increase the top tension, and/or decrease the bobbin tension. If that doesn't do it, buy a magnetic lube jar and a quart of liquid silicon and run your top thread through it. The jar I bought comes with a plastic regulator screw that can be set to just get the thread moist as it feeds through the base. It makes it easier to pull up the knots and can breathe some life back into old, dry thread.

If adjusting the top or bottom tension doesn't allow the knots to come up inside the leather, pull off the right sliding cover and watch the top thread as it goes around the shuttle. Does it hang up on the way in or out? Is there a click as the thread lets goes of the bobbin race and comes up? If so, there are further adjustments needed.

If the same thing happens with V92 thread. I would have a tendency to check the tension that you have set your bobbin thread to. Too much bobbin tension can also cause the bobbin thread from not being drawn up into the material.

Ive continued to adjust. This is 92 top and bottom with a 22 needle.  White is top thread black is bobbin. Finally looking a little better.
