Members Thescandall Posted March 31, 2022 Members Report Posted March 31, 2022 Ok, I have the Techsew 5100 for my heavy stuff, but found this singer 111w155 head only for a couple hunert. The machine has been serviced and seems solid . It should work great for smaller, thinner projects. I am now the foremost leading authority on how to work on it and service it from all the videos I’ve watched trying to familiarize myself with it.. Im going to get a table with a pedal and knee lift for it, my question is, is just a regular ole 550 w servo motor ok. And pros and cons from you guys on which one. I don’t need a position sensor. I’m already used to not having one.. there are just too many out there to chose from and the reviews for all are mixed. Quote
Moderator Wizcrafts Posted March 31, 2022 Moderator Report Posted March 31, 2022 Get a servo with a tiny pulley, like comes on this motor. You will need to calculate the length of the belt based upon the distance from the motor pulley to the machine pulley. It uses type 3L belts that are available at hardware stores and from the dealers selling the servo motors.

Members Thescandall Posted March 31, 2022 Author Members Report Posted March 31, 2022 Thanks Wiz. I saw 45mm pulleys available also. This machine hasj a small drive pulley so I can see where it really needs it to slow things down. Now you got me wondering about analog. are all brush motors considered analog. Quote

And if that don’t slow it down enough for me he has a box type speed reducer also. Edited March 31, 2022 by Thescandall Quote
Members Wyowally Posted April 2, 2022 Members Report Posted April 2, 2022 (edited) I only learned recently that one of the advantages of brushless motors is they make considerably more low rpm torque than the brushed ones. Even so, the brushed servo I have on my 111w155 with 45mm pulley works well enough for me in terms of power and low speed running. I'm not sure what my machine pulley size is compared to yours, but it looks similar. My parts stores had the size and series belt like Wiz mentioned to you. I felt like I was the resident current expert also after going through my machine, but I am not. There are a couple of them here who are lightyears beyond me. I only need to run my servo on the 3rd setting on the dial to get what I want. I have pondered a reducer but the good ones cost more than my servo! Edited April 2, 2022 by Wyowally more info Quote

That’s why I asked for guys with experience with the same issue. I’d like to start out with what works. I don’t want to have and buy things twice. Let’s get it right the first time. I Bought the 5100 a couple months ago, first sewing machine I’ve ever owned or been closer than 6’ too I realized a smaller but not whimpy machine would fit right in. It’s going to be a total build on the setup and I’m going to go thru the machine also. Im 63 and have built or made just about everything.. looking forward to it !!! I like the volume knob on them instead of the digital. I don’t like having to reach under the table to turn it tho Has to be a better way I’m open for suggestions from you guys and gals. Quote
Members Thescandall Posted April 5, 2022 Author Members Report Posted April 5, 2022 I cleaned it up and oiled it good today. It’s really smooth by hand. It pics up the bobbin thread so timing is good. I picked up the servo motor with the 45mm pully on it from Bob today as well. Ordered a K-leg stand and will make a top for it myself. Question. Is there supposed to be a bolt in the end of the shaft to hold the pulley. I know there are 2 set screws but is that it? I’ve looked all over the web and can’t find it on a parts diagram. Quote
Members Thescandall Posted April 5, 2022 Author Members Report Posted April 5, 2022 (edited) The only part I find that’s missing is the upper thread guide and the little clip that Goes at the needle was broke but I found them both online. Edited April 5, 2022 by Thescandall Quote
Members Thescandall Posted April 9, 2022 Author Members Report Posted April 9, 2022 (edited) Started working on the table today. Glued and screwed 2 pieces of 3/4” together for atop.i contacked cemented a piece of FRP on top too. I’ll put the metal edges on it tomorrow. I bought a consew k frame and fitted it all together. Recessed the top and cut the hole for the machine. I found 2 of the original hinges for the top to push it open and closed but I’m at the ranch already and the wife just called and told me the hinges and the servo motor from Bob showed up after I left so I’m kinda shut down for a bit.. it’s coming along....
