Glove sewing machine advice

[Angiemarie]

Hi

I sew 0.3mm kangaroo skin gloves. I use a home sewing machine which has plenty of punching power but would love a walking foot machine. The issue I have is the underside / inside of the leather hide sticking on both the presser foot and bed. I have tried Teflon and roller feet, magic tape on the bed, talc on the flat side of the leather or to try and resist drag.

I have also purchased a vintage Singer 66k sewing machine and added an industrial roller wheel foot which works well for the drag issue. The issue now is the motor can’t sew very slowly - it humms and stalls at slow speed so I press the pedal harder then the machine takes off too fast - no good for sewing around tight small curves such as the top of the fingers. I have tried adjusting the belt tension, servicing motor etc.

Can anyone recommend a good machine that is capable of slow speed, good feeding and doesn’t use thick heavy duty thread please? I sew with a Schmetz 90 leather needle. thanks
