True story. However, many Japanese machine are still far more expensive, even with 25% increase, depending on model

Are you referring to the genuine Juki LS-1341 series? As per spec, all four subclass machines max out at 6mm forward/reverse stitch length. However, there are some knock offs with 8mm, say Typical GC2263-1 is one of them. Hope this helps add to the conversation here.

Merrow is still manufacturing in the US, not like they used to but they are still doing stuff worldwide. I'm not quite sure about where Union Special is being made at. I can't think of much else off the top of my head as I type this.

I agree that DNU-1451 series price genuine vs. clone is close enough to consider both at least if you will. However, the price difference between the Juki LS-1341 and clones...can be substantial enough to consider a clone in this case here.

Make sure that the crank clamp with the limit screws is set correctly to give both the possibility of a 4mm SPI in both forward and reverse. It could be set so that the crank is going to give for example 6mm in one direction and 2mm in the other, if that makes sense.

Seiko STH-8BL, also known as Consew 206RB-2 (oil system) machine. At this time they were sold, for a short while, by Singer as a 531B-8BL. Again, NOT a copy, the real deal Seiko made in Japan. Singer 531B-8BL Parts

Singer 111W100. I'll take your answer off the air...(I'll send you a PM). I didn't want to hold back on releasing a glamour shot of this gem.

I got you covered, it's a Consew 166R class, see attached. Consew166R-166RB-Brochure.pdf Consew 166 Parts Book

I may have something, let me poke around. Price sounds about right.

Singer 7-31, -33 and -34 do not have a foot pedal operated foot lift, only the hand lever. We have put some cylinders for presser foot lift, but it's not pretty but has worked. Electronic solenoids work well, up to a point. See link for video of 24V solenoid with SP-1100 motor These solenoids can be of course used with the Efka motor's 24V output for foot lifting. As for speed control, I make up these speed control dials mounted external from the control box. I can set the machine from say 50rpm up to maximum 800 and everything in between to limit the upper limit of maximum speed of the motor. Speed control example video

Consew 226R is same as Seiko STW-8B. These have reverse. STW-8 is same as Consew 225. These are direct copies of the Singer 111W155, part for part, screw for screw. No reverse. Consew Owners Book, 224R, 225R, 226R.pdf Here's another one, very good information. USNavySinger111WConsew225REPAIR.pdf
