Members steadybrook Posted January 9, 2015 Members Report Posted January 9, 2015 Is anyone using a servo motor on their needle / awl machines ? If so, does it allow you to stitch one stitch at a time? And what size motor are you using? Quote
Members Darren Brosowski Posted January 10, 2015 Members Report Posted January 10, 2015 You would need a fully programmable motor but I am not sure that the starting Torque would be high enough. Quote
Members pcox Posted January 10, 2015 Members Report Posted January 10, 2015 I use a 550 watt family sew- pro on my Randall. I can sew 1 stitch at a time or I can sew continuous as slow as 1 stitch every 4 seconds. I am using a speed reducer The smallest and the center pulleys. plenty of punching power for 3/4 inch of harness leather. Quote
Members Darren Brosowski Posted January 10, 2015 Members Report Posted January 10, 2015 Glad to hear that! I always answer cautiously when someone wants to try something unusual and I am not sure if anyone has actually tried it. I might set up my Puritan with a servo.

Members steadybrook Posted January 10, 2015 Author Members Report Posted January 10, 2015 Can you post a few pictures of your set up on your Randall? Quote
Members pcox Posted January 10, 2015 Members Report Posted January 10, 2015 I can but it may take a day or two. Nothing special, belt from the servo to the small pulley belt from middle pulley to the hand wheel. the Randall really doesn't need much help with punching power. They were designed to be a treadle machine. If you ever get to run one on a treadle base you will be amazed at how easy they sew thick leather. Quote
Members pcox Posted January 10, 2015 Members Report Posted January 10, 2015 (edited) Darren I run my Puritan with a common 1/2 hp 1725 motor. The Puritan clutch gives great control. Edited January 10, 2015 by pcox Quote
Members steadybrook Posted January 10, 2015 Author Members Report Posted January 10, 2015 Thanks, I would like to see the pictures. Here is my set up now with the clutch motor. Quote
CowboyBob Posted January 10, 2015 Report Posted January 10, 2015 James, Clutchmotors have a feature where you can turn the end & have the clutch arm any direction you want it,if you put a servo on your machine the mounting bracket needs to be horizontal instead of verticle like your is because the arm isn't adjustable on the servos. It probably wouldn't be to hard to make a different mounting bracket. Quote Bob Kovar Toledo Industrial Sewing Machine Sales Ltd. 3631 Marine Rd Toledo,Ohio 43609 1-866-362-7397
Members steadybrook Posted January 21, 2015 Author Members Report Posted January 21, 2015 Thanks Bob. Does anyone have a video of a needle awl machine run by a servo motor? Quote
