So, I got the Family Sew FS-550s. I read this thread that you recommended and uh....well, I will admit that I failed my circuits class the first time I took it. All of that read like instructions to perform brain surgery in Sumerian. I guess I will just rig up a speed reducer to get more control.
It seems as though there is a small window on the slowest speed that will go slow and steady. It is hard to regulate because of the torque issue.
I am making seats for motorcycles and I need that steady slow speed that we all want for that beautiful, not so cheap leather we bought.
I appreciate so many of you filling me in on this stuff as I am new to the compound feed machines.
What do you guys think?...Better to buy a speed reducer or make my own?
