To add an additional length of lace, do a wet splice, skive the ends to be joined, glue them together. Takes a little practice to make it appear to be a continuous piece of lace.

You are missing the fact that this is as noted above, a 220VAC motor, not a 12VDC motor. Leads to the AC motor are only about #14 cable versus the heavy battery cables used on 12VDC engine starting motors. Typical AC induction motors draw up to 7x running current during starting. Circuit breakers and fuses for such loads work on both time and current. Their application will be designed/based on time overcurrent. This is to protect the supply lines, not the motor, though it may protect the motor in many cases. 160A at 220VAC is way out of range for a sewing machine motor, an obvious mistake in publishing the specifications. This would fry the supply leads in a few seconds if not instantly. Would also drag the voltage down for the building and possibly the neighbours before it blows. No one would be happy with this!

Pictures?? Doesn't sound like a clutch motor and by age definitely not a servo. So no, the motor doesn't draw any current if just plugged in but not running. Unless ... there is a short circuit or a build up of somewhat conductive material between hot and neutral connections. If someone has added a 3rd wire safety ground to the system and there could be some leakage from the motor windings to the grounded frame assuming the foot control was placed on the neutral side rather than the hot side of the line. Had a Sunbeam Mixmaster that gave you a zing if you touched it and the kitchen sink at the same time.

Post your location. Some photos would be helpful too.

What motor and controls are on it?

I assume you are asking for $1000 US (prices are to be listed in USD). Please clarify. You also need to state where you are located and any shipping information. Is it in good condition? Have you used or tested it recently? Please read the marketplace rules and comply.

The remaining photo. I doubt @hjones will be back. One thing that he fails to realize is that hi-res photos don't display in hi-res on most computer monitors, tablets, and phones, so there is really little reason to post hi-res photos here. Most people are not downloading photos from here, but rather looking at them on screen. But as he says, he knows all about IT with his 20 years of experience.

Your choice, no one is trying to put you down or force you to do anything. What's 20 years against 40 years? I manage fine with all the IT work I have done for years, starting with magnetic core memory, probably before you were born.

Please upload your photos here. 3rd party links often result in no picture when user or host change permissions, move, or delete the photos. Then the thread is useless. Check out this post for suggestions and helps. Many posts following it with more helps. Then come back and upload your photos here.

Mine is a 20-33 from about 1975. Used to be on a rusty beat up K-leg table. My wife wouldn't let it in the house. So I built a cabinet that can double as furniture. Take the head off and put it inside the cabinet, drop in a filler piece and throw a runner over it! So it doesn't look much like an industrial dress/drapery making machine any more.

Probably several models of 20U. Mine is a 20U33 from about 1975.

You could also post in the Leather Sewing Machines forum.

I checked your file sizes and don't see any problem, even with the first ones you uploaded. Maybe something on your end with your browser or your ISP? Sorry I can't test as there is no limit on the size of moderators' uploads. If you have more to post and can't get through, message me and I'll give you an address to email them to, and I will post them for you with your comments.

Interesting that your profile says you are from Chicago, but your IP address is from Ahmedabad, Gujarat, 380001, India. Are you a serious leather worker, or are you trolling?

Just to clarify, the twin needles on top with a spool for each, both threads passed through the tension disks, single bobbin thread on the bottom. The top shows double row of stitches, the bottom thread shows as a single zigzag stitch since it has to hit both top threads.

The manual says 135x9 needle system. That's not particularly an industrial needle! Standard domestic system, even though it is in an industrial tailoring machine. So the standard dressmaking twin needles fit.

That's all my wife uses is the regular needle clamp on her cheap domestic. The 20U series is beefier than her little machine. The needle clamp on my 20U is certainly stronger her domestic and stronger than the double needles. The double needles will fail long before the clamp.
