A comment on the addition of a motor to the Singer patcher. I just recently purchased an Adler 30-1 with a treadle and have very sucessfully added a motor to the machine. The Adler is very similar to the Singer 29 and should accept the same motor. And i want to say up front that NO modifications were made to the machine itself and all components are bolt on and are what I used for the Adler.
I started with a Consew CS-1001 servo motor with a needle positioner although a CS-1000 would work but not give me the functionality I wanted. I made wooden arms underneath the 4 mounting holes used to attach the sewing machine to the treadle base, Longer bolts 5/16 NC x 2 inch long attached the arms. A small shelf was then bolted to the arms which protrude rearward of the treadle base about 8 inches. The servo motor then attaches to the bottom of the shelf hanging down. I used a 1/4 inch round leather belt but suspect a 5/16 (8mm) belt would work a bit better. I did need to put a small idler wheel for the belt to clear the corner of the treadle base.
The needle positioner mounts to an adapter, included with the motor, to the shaft end of the machine with a 8mm x 1 mm pitch x 25mm bolt slotted for a flat screwdriver. A small wooden arm made to attach to the bobbin winder holds holds the positioner in place. A wood pedal and a commercial rod attaches to the servo motor for speed control.
I picked the Consew because it was a servo driven motor, has programmable speed and direction, and has a positioner. It works very well (awesome).
I can program the max speed to a slow setting and when I release the pedal the needle is programmed to be in the down position. I can easily turn the foot or material. Sew some more. I can also "heel" the pedal (make it go up instead of down) and the servo will pull the needle in the up position and I can then manually raise the foot and remove the material.
This is a machine even more fun to run now that it has the servo. And the cost was not bad either. The motor was $176.00 but it did take a lot of thinking and making of parts to mount the motor without and mods to the sewing machine itself.
