Don't expect to sew anything thicker than chaps with # 69 thread.They were made for sewing shirts,dresses & thinner material.

Also usually set up to run at 3000 stitches per minute (ie 50 per second) and harder to control at low speed.

can these be slowed down with a servo motor or a reducer pully and do they have a walking foot

1: Yes

2: No. It is just a very high speed straight stitch garment machine, with a static (but interchangeable) presser foot and bottom feed only.

Any machine can be slowed down by simply adding a Family Sew FS-550 servo, equipped with a 50mm pulley (sold by Toledo Industrial Sewing Machines). No need for a speed reducer on such a light duty machine.

The 591 contains an oil pan and has an oil pump. It must be run at high speeds (2500 to 3500 RPM) to distribute the oil to the extremities. It is meant to be run at several thousand stitches per minute (5,000). It will only sew about 1/4 inch (.26") of cloth material, with a maximum stitch length of just under 5 per inch. The bobbin is a standard Class 15 that snaps into a bobbin case on the left end, under a sliding cover. Thread handling stops at #92 (T90 bonded, or T80 heavy jeans thread). The pressure spring is purposed for holding down cloth, not leather.

FWIIW: I considered buying one of these from a drapery shop that used it for small jobs made with light material. I tested it on-sight and found that it couldn't sew 8 - 9 oz belt leather without skipping stitches, caused by the presser foot lifting with the needle on the upstroke. There is no future in spending any money on a machine like this unless it is going to make or repair cloth garments or pillow covers.

Hi Wiz,

Bobbins for this are the standard Rotary style which is slightly different to the 15/16 class

O. What letter or class of bobbin does it use?

I love this machine for denim seam sewing . Been using for a year, what a reliable go-to for random projects that don’t require walking foot or double needle. Parts easy to find. It’s a garment based machine and not well suited for heavy materials as stated above. I’d recommend to anyone looking for a simple reliable machine that can do a range of projects.
