Servo Motor For Old Singer 111

No. It means you might have as much as 35 yards of thread wound on a bobbin. In actual use the bobbin winder might stop well before than amount has been loaded.

Every stitch pulls the bobbin thread up into the leather, around the top thread in a knot, then back down. This takes up as much length as the actual stitches, if not more. So, if you are sewing a 4 foot long belt, that makes about 8 feet (2 sides) x 2 for the knots = ~16 feet of bobbin thread. This amount gets worse as the thickness increases, because the threads are pulled in even farther.

Basically, considering that you lose thread each time you finish one piece and start another one, and that the actual amount of thread needed is twice the length being sewn (for each side), you might get 9 to 10 yards of two sided 8 ounce belts sewn per G bobbin load, using #69 thread. That would be cut in half for #138 thread. If the leather is thinner, you could sew farther on a bobbin load.

Thanks Wiz, Thats the answer I was looking for, I see now why they call you Wiz. Do you know if their is anyway to modify the bobbin assembly to get a larger M bobbin in there?

I think not. Ask Bob Kovar, he may know if that is doable.

Yes,it can be changed for around $375.00 for the parts,machine work & labor,shipping is extra.It can be done for less if you can take the hook saddle off & send to us for the machine work.

Dont mind the smaller bobbin, unless u doing production work.....keep extra filled bobbins and keep the size in 138 top or 207 top...bottom is 138......all the time in mine...works great!!,..u be ok,,,but u will be falling in love

with a DC servo motor....this thing is great...u will absolutely be amazed what u can do with what a slower/slow/extra slow servo motor can do!!

Dont mind the age of the Singer 111.....it will seve u well...I had one and now have a stone old well oiled Singer 211 with sevo...love it!!!

These old Singers have soul, and the servo will put spirit in it...lets sew something...!!

I really should finish that automatic, stand-alone bobbin winder in production for patchers!

Don't let me get started on patchers, the bobbins are so small you have a hard time getting two jobs done.
