I Need To Tell You How Much I Hate The Consew Servo Motor...

[dikman]

One of my machines came with a very old Singer clutch motor, it looks a bit the worse for wear but still works well - unfortunately, I lack the skill to control it, even with a speed reducer!! As Eric said most of these Chinese servos are perfectly adequate (and affordable) for we hobbyists. While it would be nice to have a high-end servo, needing three meant it was not even a consideration. I'm more than happy with my $200 Chinese servos, they're perfectly adequate for my needs.

I just a got a new modular $200 servo motor from SewPro which is 1100W strong and starts at a low 100 RPM. I have high hopes for it, but haven't installed it yet for testing. I'll report back this coming week after some testing.

Since you asked, I can already feather a clutch motor down to 1 stitch per second, using the standard control arm and proper adjustment of the slack bolt and return spring. However, a long extension arm would make it easier on the ankle to hold it at slow speed.

Cecharo has a bunch of good videos but is also very experienced so he may be making it look  easy. Plus remember getting started in upholstery leather is different then pounding thru vegtan or such so keep that in mind. 

 

Reminds me of the old adage for hopped up street cars, 

Fast/Reliable/Cheap pick two. Seems it works for servo motors as well.

I think you mean Cechaflo on Youtube. He's a master of the manual step backwards. It seems he only uses his machine's reverse lever when he doesn't care where the stitches go.

Yeah thats who I meant. I watched a bunch of his videos to help learn how to upholster motorcycle seats. He doesnt talk much but shows how to do things very well and is quick to answer questions that are posted to his videos.

In defense of Consew servo motors, I recently put together a $110 Consew Premier CSM550 motor with a 50mm pulley and a 3:1 speed reducer to power my Consew 225. Below is a video of this combo sewing 6.2mm (15oz) veg tan leather using size 138 thread and a size 23 needle (I misspoke in the video). To me, this cheapest of servo motors plus a speed reducer (that cost more than the motor) leaves little to be desired in terms of consistent low speed control and punching power. I'd love to see somebody do this with a clutch motor.

This reminds me of the 125 pound Adler 204-374 flat bed walking foot machine that I bought privately in 2010. It had a 1/2 HP clutch motor with a 2" pulley feeding a 3:1 speed reducer. I could easily feather it down to 1 stitch every few seconds. The top speed was all of 2.5 stitches per second. The beast could sew a solid 1/2 inch of leather with #346 thread. I traded it off for a Union Lockstitch Machine.

That is a very good useful video Uwe. I have now bookmarked it.Thanks again for sharing.

Hi there,

 so do you mean this method will not produce the necessary torque to go through vegtan .?

I dont know to be honest, was just commenting on the fact that he was using 2-2.5oz upholstery leather doubled up on the seam. When you start sewing vegtan the torque goes up considerably for that first stitch. It will probably help albiet not as much as a servo motor. It is a cheap and easy mod so worth giving it a shot to see how it works for ya. 

Plus practice, practice alot. Thats how guys like Wiz can chug along with a clutch motor (with these other mods) and maintain control. Now if you have a clutch motor setup for upholstery with a big pulley on it and a small one on the sewing machine its going to be hard to handle at real slow speeds but that isnt what it was designed for. Now a clutch motor with this mod plus a small pulley on it and a speed reducer or large pulley on the machine and a good clutch will help control considerably.
