Members Gymnast Posted May 11, 2019 Author Members Report Posted May 11, 2019 (edited) I saw this special thread stand from Australia. It has like an antenna on it: The video also tells you about metallic thread to be a challenge. The video do not have HD quality, but I think that the thread comes off the spool clockwise (i have seen examples of the opposite). Then the tread actually go around this antenna anticlockwise, when it moves forward. This should be good. I think, that this going anticlockwise around something also can be done a Little further away from the thread stand, and in a way that ads more tension. I tried a DIY version of this thread guide: Edited May 11, 2019 by Gymnast better information Quote Sewing Machines in Detail, YouTube channel
Members chrisash Posted May 11, 2019 Members Report Posted May 11, 2019 (edited) With small cops you can change the direction the thread comes off the cop by turning it upside down, as there is no obvious bottom like larger cones Edited May 11, 2019 by chrisash Quote Mi omputer is ot ood at speeling , it's not me

I placed the spool at a platform near the ceiling and liftet the thread up through an eye at let the thread go controlled down to the floor with a clips on the end. For the red Serafill 20 thread (polyester continuous filament tex 135) I counted 6 turns anticlockwise each meter. It is from a 2500 m spool. I did se same for a Serafil 40 Black thread and got the same value. It is from a 1200 m spool. I suppose this could be one way to quantify how much twist you have in the spool. For the test of these two spools, the perimeter om the spools were 0.163 m and 0.160 m. The 6 turns each meter fits an asumption, that the thread do not have internal moments (twisting) when stored on the spool. The twisting is added by taking the thread off the end.

Members Bert51 Posted May 11, 2019 Members Report Posted May 11, 2019 This is the Thread Stand I was using with a domestic machine when I was having problems, rather then make a new stand to give me more height I brought a industrial Machine and set it up at it's stand at the maximum height I could. I don't think it would be to hard to make a higher top bit if you used heavier rod, then I did. Quote
Members Gymnast Posted May 12, 2019 Author Members Report Posted May 12, 2019 I made one more video in three parts of how a thread comes off the spool in three situations. 1) One thread guide and pretensioner. Result: kinks 2) One thread guide, 4 turns clockwise around something and pretensioner. Result: kinks 3) One thread guide, 4 turns counterclockwise around something and pretensioner. Result: OK and nice Perhaps a few readers did not notice the implications from the first video therefore this video. I think the thread comes off the spool over the top end clockwise in most cases. If the thread comes off counterclockwise, then this problem might not be that severe. I noticed, that more youtube videos and manuals on how to thread an industrial sewing machine actually make the thread go clockwise around something in the start. I do not think this is wise, if you have got thread like this serafil 20 or perhaps more difficult thread. This is an example of such a video for a Techsew 2700 (see from 1:20): I think it should be easy to make the thread turn counterclockwise the two first places on Techsew 2700. Here is another video on a Pfaff 545. In this video the thread turns counterclockwise in the start - so it is how I like it Quote Sewing Machines in Detail, YouTube channel
mikesc Posted May 12, 2019 Report Posted May 12, 2019 (edited) I noticed, that more youtube videos and manuals on how to thread an industrial sewing machine actually make the thread go clockwise around something in the start. Maybe that depends on if the person threading is right handed or left handed..some of us can use either hand, or both, some due to accident / injury / illness are more restricted. I saw a video a while ago on the BBC about a girl who was born with no arms, who operates her sewing machine ( including threading etc ) with her feet.

I saw a video awhile ago on the BBC about a girl who was born with no arms and who operates her sewing machine ( including threading etc ) wit her feet. Yes, perhaps. The Techsew video is an official Techsew instruction. I noticed this Juki 1508 manual with the clockwise turn on the first steelplate. http://www.juki.co.jp/industrial_j/download_j/manual_j/lu1500n/menu/lu1508/pdf/instruction_7k_1508.pdf#page=1 I know that deviating from manufacturers threading instruction can have some issues. However it may be a way forward when your thread is kinking. Quote Sewing Machines in Detail, YouTube channel
Members Gymnast Posted May 19, 2019 Author Members Report Posted May 19, 2019 (edited) I just got a little update on this subject. I noticed a video from Rusty, Springfield Leather Company, with a thread leaving the spool anticlockwise when you look down on it. Most spools I have seen is the other way around. If you have read the information in this "thread", you will notice, that a thread comming off this way around should be easier to handle. The video is this: Edited May 19, 2019 by Gymnast Quote Sewing Machines in Detail, YouTube channel

The thread in the video is indeed coming off counter clockwise. Your comment on noting the un-spooling direction of the thread sparked me to do a quick checked of my spools of threads, which I really didn't pay much attention to in the past. What I found was: 1. My no name probably cheap Chinese 8 oz black and white nylon comes off clockwise. 2. All my Coats thread various colours (nylon and polyester) comes off their 1 lb spools clockwise. 3. My American & Efiro black nylon thread comes off counter clockwise. From this it is obvious that different manufacturers are spooling their thread differently, may have something to do with thread size, thread type, spool size or some technical spec. Maybe one of the dealers could do a quick check and see if their thread in different thread sizes comes off the spool differently. For me the direction of how it comes off the spool doesn't seem pose a problem but more related to the size of the spool, 8 oz vs 1 lb with my problem child being the 8 oz spool. kgg Quote Juki DNU - 1541S, Juki DU - 1181N, Singer 29K - 71(1949), Chinese Patcher (Tinkers Delight), Warlock TSC-441, Techsew 2750 Pro, Consew DCS-S4 Skiver

Right, with your redesign of the thread stand by rolling off the thread, it should make no change, because I think the bonded thread will be in a "relaxed" state when stored on the spool. So some twisting will be introduced by the thread comming off the end of the spool, which is the normal case for leatherworkers. For my little machine, I am sure, that I had to make the threading different in the two cases according to this spooling direction. I watched two other videos on threading of Cowboy machines from SLC, and they show spools with thread comming off clockwise. Quote Sewing Machines in Detail, YouTube channel
