Members IvoryCreek Posted February 10, 2017 Members Report Posted February 10, 2017 Hi there, I have a flatbed heavy-duty Sailrite LSZ-1 that I've been playing with and I've found the speed very difficult to control solely by the foot pedal. Looking at videos on youtube, I learned that Servo motors can be bought to retrofit old sewing machines, I wonder if I can do the same with the Sailrite LSZ-1. How would I go about this to figure out if it is possible? The motor on this LSZ-1 is attached to the sewing machine. Another idea I read somewhere is to add a voltage regulator kinda thing that can more precisely control the speed compared to using a foot pedal...no idea how to do this though please help...thank you all!

Moderator Wizcrafts Posted February 10, 2017 Moderator Report Posted February 10, 2017 Is your machine already equipped with the Monster II balance wheel? If so, does your foot pedal start at zero and slowly increase to speed, or does it change abruptly from zero to some speed too fast for your liking? If your pedal has a jumpy start, contact Sailrite about a replacement pedal. If you don't have the Monster II balance wheel, order one, along with the proper longer belt.

Members ZigZag Posted February 10, 2017 Members Report Posted February 10, 2017 I've used an LSZ for a few years now and have found the speed control pretty good, so maybe Wiz is right about a faulty foot pedal. I would also agree with upgrading to the Monster fly wheel. Makes a big difference when working with thicker fabric.

Members IvoryCreek Posted February 10, 2017 Author Members Report Posted February 10, 2017 Thanks guys. I can give the Monster II wheel a try, but is it just a heavier balance wheel compared to the one that came with the machine (which can also be hand cranked)? how does that help speed control? I think the pedal doesn't spike, it's just the slowest speed is still quite fast leaving me little control. and it accelerates quickly if I step a tad harder. Quote
Members Yetibelle Posted February 10, 2017 Members Report Posted February 10, 2017 Going from nothing to full speed with a slight press then its probably a pedal issue. Here is the info on the Monster wheel, plus look at the other Learn to Sew videos Sailrite has and if your machine does not have the same speed control as the machines in the videos then you know you have a faulty speed control issue.

Members ZigZag Posted February 11, 2017 Members Report Posted February 11, 2017 The pedal on my LSZ lets me creep along at very slow speeds and is progressively faster when pressing the pedal. It is sensitive and needs careful foot pressure, but by no means spikey in speed delivery. The guys at Sailrite are great, I'm certain they will help you out if there is a problem.

Members IvoryCreek Posted February 11, 2017 Author Members Report Posted February 11, 2017 Thanks ZigZag and Yettibelle, it sounds like my pedal may be faulty, I'll talk to Sailrite about this. What I’m observing is when I step on it gradually and slowly, the motor will first start making a buzzing sound, and once my foot steps past a certain point, the wheel starts to accelerate to its minimal speed, which is already quite fast. Then if i step a little more, it's really fast... Thank you all! Quote
Members sandyt Posted February 11, 2017 Members Report Posted February 11, 2017 (edited) What are you sewing with this machine? Are you testing the speed control with or without material under the needle? Edited February 11, 2017 by sandyt Quote
