foot lift ?

Ron Anderson probably has more information on this beast. I've only seen one. It appeared to be the same as most of the low-end Singers. One of the kids in one of our classes a couple of years ago had one. It apparently was nothing but trouble and she had a different machine for the next class.

It is no different than any of the low end Singer machines. Basically the same machine with a tank body that will do nothing for the sewing. To put a figure on it 5-7 mm before the tension release engages. Sewing over the hump in jeans hems is more technique than machine. Most home machine and even many industrials choke on going from 2 layers to 8 all of a sudden.

With an assist from my handy dandy "Jean-a-ma-jig" I hemmed two pairs of jeans yesterday. At the inside leg seam (at the flat-felled seam) the thickness of the hem was 9 layers of denim. My 1960 Singer 401A didn't miss a beat. I start just before the seam with the hump-jumper *behind* the presser foot, sew over the seams, then place the hump-jumper in front of the foot, with the slot centered where the stitching will go and sew until the presser foot passes over the hump. The idea is to keep the presser foot level going over the thick fabric. Works perfectly. Before I bought a commercially made device, I always saved the scrap of cut-off hem and used it behind and in front of the presser foot when hemming thick jeans. I also steam and hammer the combined thickness.

product is the "Hump Jumper":

Can't tell you about the machine, but do you know about sewing hammers? No, I'm not kidding.

use a plastic-faced deadblow mallet for jeans.http://www.rockler.com/product.cfm?Offerings_ID=11069Kay
