I spent some time today looking at the inner presser, and I found that the thumb screw over the inner presser bar was turned all the way in. I backed all the way out and then turned it in 2 turns. I then ran some stitches and found that the top tension had relaxed resulting in the loop moving to the bottom and the bobbin thread became a straight line. Not sure, way relaxing the tension on the inner presser foot would relax the top thread tension.

How are these connected?

You will have to play with a combination of adjusting the pressure springs for the inside and outside feet to find the magic spot that doesn't pucker the material or the thread.

Ok, I have the top thread tension, the bobbin thread tension, the inner presser foot spring and the outer presser foot spring at there lightest settings and the machine is able to sew the material and the material is staying flat after it is sewn, I am also able to achieve the correct stitch length now as well as the maximum stitch length that the machine is capable of in the material.

I also change the presser feet from 240517 and 240518 to 240148 and 240149 which help as well, so I now have a 2 toed outer presser instead of a left toe only outer presser foot.

I sewed some upholstery leather at these setting as well to see if it would sew at these setting and it does, but a little more top thread tension is needed to balance the stitch which I did not do since I need to work with the Spradling Dolce first.

Seems the previous owners of each of my machines have been running them at or near max tension on everything.  Now I have a better understanding of why I have been breaking the needle thread on all of my machines as well. I will have to go though each of them and relax everything and then balance them out.

Thank you.

 Note, that a tailoring machine can often be retrofitted with a roller presser foot. It requires raising the presser bar as high as it will go. There are 3 piece kits that replace the foot, feed dog and throat plate. A roller foot machine has a single row feed dog. They are available in different courseness of teeth, from light to heavy duty grip.

I found the kit you are referring to. I thought a roller foot was a high shank foot with rollers in it, not an arm with a wheel on the end.

I found one that has 2 different size wheel that I will try on my 95-10. Hopefully I can get the stitch length to 7 spi instead of 8spi in material.

I found that part of my problem was due to the needle pushing the material into the feed dog. After I purchased a feed dog with a needle that match my needle size the problem significantly improved.
