    Juki 563L

    Its a vertical, like the Singer 111/211/Seiko LCW-8BL etc (pictured).

    Juki 563L

    I've had 3 LU-563's...none of them have ever had an anti-backlash spring in the bobbin basket. Frankly, I didn't know such a thing existed, but that certainly means nothing. Most of the work product you will encounter on a site such as this is quite often produced by machines using *speed reducers* ; The anti-backlash spring is more a fixture of balls-to-the-walls garment or other fabric trades, where you run the machines at speeds close to the maximum your 3450 rpm clutch motor is capable of, punctuated with ABRUPT stops at the end of a stitch line. The anti-backlash spring helps overcome the spinning inertia of the rapidly rotating bobbin when the thread demand STOPS INSTANTLY, otherwise you get a mess of a bird's nest reminiscent of what you'd see with a bad cast from an old-school bait casting fishing reel. That flat blue spring is very often furnished with the bobbin cases of many horizontal axis machines, but I've never heard of one for a 563, and never seen one called out in a Juki LU-563 parts list. Unless you are doing long runs like production shop marine applications can require, I'd guess you will never miss it in your Juki. BTW, I'd like to see a picture of the model badge on your Juki...I'm not familiar with a 563L subclass. -DC
  3. This is a generic clone sold under several "badges" and quality levels. Sort of a Singer 45K inspired type of machine. The GA5-1R has reverse. Google images has a zillion to compare. -DC
  4. Google "Techsew 2800 standard sewing set". -DC

    $50 white whale SCORE! Singer 29-4!

    Those are "pre-wound" bobbins which are commercially produced to eliminate the metal bobbins in industrial machines. The "style" for a 29-4 is a (number) 19, the small bobbin patcher size, whereas the "large bobbin" version is a style (letter) I as far as I can tell. I have no idea who may still be offering them. -DC
  6. Nakajima also made this machine as a "DD-N73" and branded it Yakumo as well. I would suggest that anything branded by Nakajima or Seiko will be very good quality. There are hints that this machine was their take on the Singer 45K. -DC
  7. Strongly suggests bent needle bar to me. -DC

    I want to restore a Singer 111W153

    The tag does say 153....but I have no explanation for it. The machine certainly LOOKS like a model previous to the 111W15(X) models. The common wisdom says they changed the stitch length adjustment from the dial on the handwheel to the stop button on the bed and a stitch length scale you viewed through a hole in the column after the 111W152 model (I have a W152 and it is fitted out as described), and also added a safety clutch to protect the hook, also with its own button in line with the stitch adjustment stop button. You can see the pretty prominent pair of buttons on the bed in the picture posted. The single button you refer to may be an oiler ball zerk, in the depressed area behind the bobbin cover plate. It really only matters if you are trying to find some of the parts for the earlier type machine in a W153 manual. I know several here own examples of the earlier 111W machines and can perhaps explain when the W153 runs actually began. -DC

    I want to restore a Singer 111W153

    Are you sure this isn't a 111W103? It has the older stitch adjustment knob on the handwheel and no buttons protruding through the bed like the 111W15(x) series machines have. -DC
  10. The easiest way to straighten that bend is to remove it from the top cover, then put the bent portion between the jaws of a good vise and press the bend out. Hammering may be a bit too violent for the scale of the part. -DC

    Pfaff 335 ... some questions

    I'm not a Pfaff guy so I'm not sure how much of this applies to the old casting machines- my charts show: H3 = Top feed lift 5.5mm, 11mm foot lift 734/ = Gathering mechanism (top drive) 921/ = optical top feed variation indicator 6/01 = standard parts for plain sewing ops B = For medium materials S = Fabric -DC

    Servo motor quit? Why?

    The noises it makes suggest it IS spinning when you activate the pedal....if the shaft is not free-spinning inside the pulley (broken/missing key) or loose set screw/nut/other fastener, then its possible the output shaft itself could be broken at a point past the brushes. Stranger things have happened. These old-school brush motors with a max-rpm limit dial have been used in some form on sewing machines since at least the 70' example is seen here on the old White model 970 from way back. -DC

    Singer 153b8b

    Heavens no. That is the manufacturer's description of the MAXIMUM mechanical foot lift available, and like any other machine, its designed to unload the thread tension a good bit before that height. Technically it might sew, but it won't make viable stitches. My SK-6 lifts almost 16mm by pedal, but only will sew about 11.5mm. -DC

    Singer 153b8b

    The model number certainly suggests some Seiko/Consew heritage (AKA the Seiko CW-8B)...and at the least, that *B* in their models usually indicated the larger "M" style bobbins. The Seiko specs for the CW series show a max foot lift (by pedal) of 14mm, and a max stitch length of 5mm. -DC
  15. The feet on this machine seem to be set up for applying tape to a seam....has the tape slot *made in*, along with a centering guide on the inner foot. The gauge set for your desired needle spacing will have a new needle plate with the feed dogs and needle holder. If you are making *gear* with the frequent 3D internal shapes, this could be worth hanging on to. The needle system is a good thing too, loads of choices, brands, sizes. How does the stitch adjuster on this one look? Lots of machines that were used in factories for a dedicated operation had some features (like the stitch length) disabled so they couldn't be tampered with or adjusted by the operator. Could be trivial to reset to original. -DC
