February 21st, 2007 : Tacsew T111-155 Modifications
Working with an industrial machine is not the same as working with a household machine! The Tacsew flies, man! And, as a novice, I needed more control and to go at a much slower pace than I will later, when I get some experience under my belt. The servo motor definitely helps ... but I made a couple of other modifications that you'll appreciate if you are also a beginner with an industrial walking-foot sewing machine.
The first thing I did was to modify the treadle. I was surprised when I hooked the treadle up to the motor and saw that the treadle has only an inch or so of movement while engaging the motor! That doesn't give you much room for playing the treadle, if you will ... so I added an 8-inch extension bar to the motor switch-bar and increased the treadle movement to 2-3 inches. This helped to give my foot more play room and more control over the speed of the motor.
Even so, however, it was still very difficult to maintain a slow-moving action while sewing, so I made a second modification on my Tacsew by installing a much smaller pulley on the motor. Now this really made a nice difference! I'm now able to sew at a nice slow, comfortable speed and take my time, adding more care and precision to my work.
I noticed, whenever I was cutting threads after making a stitch, that the threads were not only difficult to grab at times but my most natural tendency was to brush them to the side, grab my garbage pail and wisk them into it. That gave me the following brainstorm:
Update: April 3, 2007
For $149.00 and free shipping, I decided to add this SewQuiet servo motor to my set up because of the control features it offers. Aside from the fact that it uses less electricity and is on only when you step on the pedal, the control features allow you to slow down to a snail's pace which is very helpful when sewing corners or when doing detailed work ... or when you are just a beginner, learning how to handle these machines.
