Members trash treasure Posted October 15, 2021 Members Report Posted October 15, 2021 As Wiz said, the 20U is an all purpose machine - The one we have has proved excellent for many years. Quote The model number giveth, and the subclass taketh away ......... Sometimes

Also parts were available for a straight stitch needle plate and feed dog. I picked a set up about 5 years ago. Quote
Members williaty Posted October 16, 2021 Author Members Report Posted October 16, 2021 Hmm, sounds like I need to keep an eye out for one. They previous ones I saw before I started looking for a ZZ machine went pretty cheaply. Quote
Members trash treasure Posted October 16, 2021 Members Report Posted October 16, 2021 One other thing about the 20U - They were never really factory machines, being sold mainly for tailoring use, so you usually find them in pretty nice shape, and not worn out from 3 shift, 24 / 7 type use and abuse.

Members Gymnast Posted October 18, 2021 Members Report Posted October 18, 2021 (edited) I have read about the Singer 20U, that it characterized as a 3/4 size machine. So I guess the harp area right of needle is less than a Pfaff 138. I Know that the Pfaff 130 got about 205 mm right of needle as a full size domestic sewing machine. I saw a sailor forum with a guy, that had got a used Dürkopp Adler 525i for about $1500. https://www.duerkopp-adler.com/en/main/products/shoes_FB_ZZ/525i-811.html https://www.duerkopp-adler.com/commons/download/public/525i/B_52Xi_EN.pdf It can be configured 1:1 with motor, and then the speed is 3500 stitches/min. But 1:2 with motor is also possible to half speed and more torque, and I guess this will be most applicable here. It got a harp area of 265 mm. So I guess this machine is both for high speed and somewhat heavier work. I am impressed by the possible very low speed of the servo motor of only 10 RPM. It is excellent. Normally I have seen the minimum speed of brushless servo motors to be at least 100 RPM, but Dürkopp Adler may have an extra low speed feature here, and as far as I can see, it is a brushless type motor. The speed specification can be found at page 15 here: https://www.duerkopp-adler.com/commons/download/public/525i/0791_523901.pdf Edited October 18, 2021 by Gymnast Quote Sewing Machines in Detail, YouTube channel
Members DrmCa Posted October 23, 2021 Members Report Posted October 23, 2021 Flatbed zz machines are used in making male suits. This is lucrative business, so they are pricey, even used.

Members councilman24 Posted November 2, 2021 Members Report Posted November 2, 2021 I'm in SW Michigan. Singer 20u's are all around us. IMHO ONLY buy a blue or tan Singer. Chinese made clones branded singer, consew and a dozen other brands are available as cheap as $300 for the head. I have several zig zag machines. All but 2 were bought locally I have 3 20u's, 2 Pfaff 238's, 4 Bernina 217(n),s including one 12m wide, 2 consew 199r-2a's that are double through zig zags. As cheap as $300 amd one of the bernina's with a cam drive for various stitches was $750. Also an old singer not mentioned above that I can't remember the model number if. It doesn't tension release sp anything you can compress and stuff under the 1/2 clearance foot you can sew. I also have a sailrite zig zag because it was cheap but have never used it. All except the sailrite are dropfeed only. But I know a parachute container manufacturer that uses a 20u to close the corner of the rig. Seam includes 4 layers of cordura and or parapack and 4 layers of nylon binding tape. A bernina clone is sold by Global for sailmakers. Can.be had to do a triple throw zigzag and mount a puller to the back. The consew 146 is a compound feed zig zag. One rigger I know bought one thinking it would up his capability. Not so much. Keep looking at craigslist and fb. But you have to look at every post. Many post have one bad photo and say sewing machine $200. I've gotten many good deals by being able to tell what they were and fix minor things wrong. One of the Bernina's I got for $450. I told them they should get more and it was worth more but not to me as my 5th zig zag. Left the offer standing. No other buyers in 2 weeks and they called me back. Keep looking. And contact me.
