Nathan Johnson Report post Posted August 12, 2014 Hello glad to find this forum. I just bought a 241-2 from an estate sale. Need to know any information anyone has on this machine. Will this machine do good on leather. I am going to try to use it also on leather uphostery in automobile. Are parts hard to find for it since it is so old? It has a 203 volt 3 phase motor what is it going to take to change to single phase? Any help or comments. Thanks. Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted August 12, 2014 You can replace the motor with a new servo motor. That will give you a wide range of speeds. But, it has a sump pump and is built to be run at about 4,000 rpm, or stitches per minute. This works out to maybe 60 stitches per second, plus or minus 6. At its maximum stitch length it will move along at just under one foot per second. The thread handling capacity is perhaps #92 bonded, but more likely, #69. These machines normally sew with cotton or polycore thread, not bonded nylon. The presser foot lifts to about 5/16 inch and sews about 1/4 inch of material, or so. The needle system is made for garment sewing, using cotton, polyester and denim cloth. It will have trouble going over seams because of its basically flat foot.

Nathan Johnson Report post Posted August 12, 2014 So this machine may not be what I need ( to fast, no good for leather). What would it cost for a single phase motor? I may just fix and sell or part out. Thanks for your help. Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted August 12, 2014 Single phase 110 volt clutch motors go for about $100, or so, shipped. They are heavy. Servo motors are lighter and very easy to control over a wide range of speeds. They cost about $115 plus shipping. If the machine will be kept and used for any leather sewing, a modern servo motor is recommended. Clutch motors are usually off to the races, unless you learn to feather the clutch. Keep in mind that your machine is self oiling and must spin fast, often, to distribute the oil to the ends of the wicks. The oil pan must be filled to the etched level inside the pan and the pickup filter kept free of debris. By spin fast I mean well over 2500 rpm, or pedal down. Some folks do this to wind bobbins and before a day's work with the machine. Quote Share this post Link to post Share on other sites
Darren Brosowski Report post Posted August 16, 2014 The machine can only sew light leather. If you fit a servo motor and run at low speeds then the bearings designed for 3000 rpm will have negligible load on them and will run for another decade or so. As the machine cost very little it is a good return on investment if it will sew what you need. Quote Share this post Link to post Share on other sites
