What Thread Size Is About 1Mm In Diameter And Can A 441 Clone Sew With It?

Hi, the mid wheel is a the hand wheel, it's only a pulley on the back. You got to have extremely long arms to reach a conventional hand wheel on the back. I bought that machine very cheap, just for that same reason; it was to big to handle. Anyway, I traded it in a cylinder bed that I sold again. The result was I got ten times the money I paid for it and that's not bad. If you get it cheap and have the space for it, sooner or later somebody need one and will pay you good money for it. Remember, such stretched machines cost four times a normal one. However, storage cost money too.

The shuttle on the 144 class is not going to handle anything heavier than #345 and that is pushing it.

At most I would run 207 through them on a regular basis and 277 on top.

Unfortunately the industry is dominated by dealers full of bullshit who know nothing about true heavy sewing. There are a small number of specialists who know what they are talking about and they are pretty much all sponsors on this page. Talk to them before wasting your money on a machine that will not do the job.

Sorry mate, I cannot agree with you on that:) I have own and used this machine (144W-305 picture in my post #19), it can take up to needle size (Singer 27= metric NM 250).The needle system is 7 x 3, that's the same length as a 794 needle I am using in my 441. My machine sewed polyester thread tkt 8 ( tkt 9 is tex 350 in the same thread) that means that tkt 8 is even heavier than that. I used a needle 230 for that (Singer 26). So that means this machine will run Tex 415 without problems. And that is also stated in its manual. I have never tried this myself, because I could not get that heavy thread size here in Norway. The previous owner used it in production and it was set up with that same thread size; tkt 8. It sewed that all day long, that size is well in its comfort zone. And make no mistake, this is a monster of a upholstery machine. Nevertheless, that does not make it a leather machine, they have shuttle hooks. It was often used in the car industry, sewing vinyl and upholstery leather true wooden door panels. Anyway Darren, I see your point; dealers often tell you anything to sell a machine.

Hello group,  This is a really old thread but I want to add some information.  I have used a US made braided polyester thread that is size 415 and size 277 (bobbin).  I contacted the manufacturer over a technical question as I discovered an issue with it.  They said they are making it in USA proudly and as long as sources for the fiber don't dry up they will source the fiber in USA.  If forced they will only source overseas and still braid in USA if supply is no longer available.  I put it on my thread stand and it twisted hence the reason why I contacted. With the braided stuff it is stronger than regular equivalent sized thread and is not sensitive to right/left twist requirements.  However when feeding off a regular thread stand from the top it will twist up.  The answer is to feed off side and let the entire spool turn as it unwinds to feed the machine.  They have tan/brown/black/white waxed/bonded.  Same seller below is selling gun holsters so must be using them successfully with their biz and it is obviously listed for leather work.  However, something I want to try is an 8 braid (that makes it a round braid coming off a maypole braider) UHMWPE fishing line.  I just ordered some rated at 80lbs and color dark grey with 0.5mm.  Using Bob's chart that puts it on a size 23 needle which is capable of many of the machines that would be used for wallet leather etc. that max out at size 23 and the size 207 is 0.508mm so this will be ideal.  The 42lb stuff is barely smaller in diameter than ticket 30 so would be a good candidate for the bobbin in a machine like a Singer 112w-139 compound feed sewing wallet type leather.  These types of lines are much stronger than polyester or nylon and UV resistant unlike nylon with much greater abrasion resistance than even the best of nylon but the Achilles heel is very high heat temperatures.  If I wanted max bang out of smaller threads on my Singer 112w-139 I believe this 8 braid fishing PE (UHMWPE) line is the way to go.  Here is the link for the USA made stuff but I will try the 8 braid 80lb PE fishing line and am fairly certain it will be amazingly strong.  I might try to figure out a better smaller size for bobbin as well.
