Singer Heavy Duty, Most In-Depth Review on the Internet. No Really, I'm Not Joking.
This is the review you didn't know you wanted to see. I tear down this sewing machine and see how it was constructed. Here it is, The most in-depth review of the Singer Heavy Duty Sewing Machine. I go through all of the components and determine if this is indeed a "Heavy Duty" sewing machine. Singer has made many sewing machines through the years and this should be the culmination of all of the research to date. We will see how it handles multiple layers of cotton, denim and thick leather. Including taking readings of motor current and power.
