Recently you wondered if one of those cheapie Singer Ebay Heavy Duty sewing machines could sew a ratchet strap. The answer is yes but of course a true Industrial machine would be better. Below are the pictures. I am using T70 (#69) bonded nylon thread. The thickness of the two straps is 1/4" which is the maximum the foot on the machine will lift. My heavy duty needles haven't arrived yet so I used a regular needle but it didn't present a challenge to the machine (heavy leather might be a different story). The stitch length is set to 4, which is the max, but the stitches are still pretty close together. I'm sure an industrial machine would allow a greater range as long stitches are desirable for some leather an upholstery work. Also the thread holder post on the Singer works with regular consumer thread spools, not large industrial types so I had to improvise.
