  1. Modern high performance threads

    The honest truth, is that I like working with unusual and high performance materials... There is no reason other than that I do currently use v69 right throughout my wallets though, it has held up well so far - what are you using for your main wallet stitch line if only using v69 for wallet internals?

  2. Hi all, Does anyone have any input on what could be considered the strongest modern machine sewable thread for leather? I currently use a bonded nylon #69 thread which is fine, but I do wonder what the strongest machine sewable thread may be, I'm thinking in terms of Kevlar and Dyneema (or others?) - does anyone have experience with high tech threads? I understand there comes a point where the thread is significantly stronger than the leather, however I'm wanting to avoid that part of the discussion. -p
  3. Pfaff 335 motor 'sticky'

    THANK YOU everyone - you're all right, it is the clutch being in brake mode when the machine is stopped. If I run the pedal very lightly, the stiffness disappears - thanks so much, I was getting all worried about having to fit a new motor or something
  4. Hi all, I have a Pfaff 335 - the older style, image attached as an example. I'm having an issue which appears to be getting worse, whereby the motor is hard to turn/sticks. It's not the machine, if I take the belt off the machine itself turns over smoothly. That being said, the clutch/motor still works perfectly fine, and you wouldn't notice it if you didn't hand crank the needle into position or around tight spots. I'm just wondering if this is normal behaviour/the motor is wearing out/bearings are toast/or other. Am I not doing something maintenance-wise? My other two machines are much newer with servo motors so I have nothing to compare - I also live in a remote place without access to industrial machine mechanics. Any help greatly appreciated! Cheers!
  5. Juki 1508 leather tips

    Cheers - sorry to be a pain, but are you able to show me a link to the bits you changed on your machine?
  6. Juki 1508 leather tips

    Ohhh, please tell me what changes you've made to your machine since we have the same one! I've tried loosening off the presser foot just now, and I'm still having a track issue, particularly on the shiny side. Did you do the aforementioned sanding mod on the feed dog?
  7. Juki 1508 leather tips

    Thanks, I will try re-adjusting the foot and buy another feed dog to sand down. Regarding thread size on your chart, I have a lot of 69 (T70) [Tkt 40] - is this strong enough for wallets or should I move up to my original idea of 138 (T135) [Tkt 20] ?
  8. Hi all, I have a Juki 1508 (1508NH specifically) that I am now experimenting with for production wallet sewing. This machine, along with my others, have primarily been used for canvas work and I'm very inexperienced with leather sewing. I pulled out some leather scraps yesterday and now understand it's going to be quite a bit of fiddling to get a nice finish! I was hoping I could get some advice on some immediate issues - I have no access to a machine mechanic because of where I live unfortunately, however this machine will be dedicated to this one task, so it can be tweaked for its purpose. The presser foot & feed dog are leaving tracks along my leather. Can the presser foot be replaced with something made of nylon? Are there special 'leather feed dogs' which have less aggressive teeth, or is it all about tension and adjustment? I'd like to use M20 nylon bonded thread - what is a leather point needle recommendation for this thread size? I need to slow the machine right down (clutch motor) - is a smaller pulley the way to go or must I get one of the more specific speed reducing pulleys which also gear the machine for torque? The Nick-O Sew dual speed reducers on eBay are nice, but after USD conversion and shipping to Australia it's an expensive bit of gear. Thanks so much! -m
  9. Hi all, I've recently picked up a Pfaff 335 which features a synchronised binder - I have a 14mm shell, but I'm after a 19mm or 20mm shell for this machine, but I can't seem to find one anywhere. Is anyone experienced with these machines, or know of any stores which sell a range of shells for them? Cheers, -M
  10. Pfaff 1245, Juki 563, Or Chinese

    I ended up finding a Juki 1508, only used for 6 months, shipped to my city for $1600USD, so pretty happy with the outcome in the end!
  11. Pfaff 1245, Juki 563, Or Chinese

    With the Singer, are parts and accessories like binding attachments readily available? If in future I like the machine, could I upgrade it to a servo motor? Also, I have stumbled across many of your other related posts (they constantly come up in Google when researching machines!) - thanks for putting up so much valuable info.
  12. Pfaff 1245, Juki 563, Or Chinese

    Thanks for the feedback! Wouldn't you know it, the Juki has been for sale for two months, and sold yesterday! Any thoughts on the Singer 132K6 as an alternative? My only concern with this era of machine is lack of reverse.
  13. Hi all, I am overworking my Juki DDL-555, sewing through multiple layers of canvas, leather, seat belt webbing, and other materials it wasn't really designed for. Therefore I'm looking at a walking foot, and the Pfaff 1245, Juki 563 are available nearish to where I live. The Pfaff can be upgraded to a servo motor and would come in at around $1100USD, the Juki around $680USD with a clutch motor. They are both gold/bronze coloured, so built in the 80s sometime. Are these machines overpriced? Any other machines I could be looking at? Availability is always the issue, ie. Consew 206's aren't anywhere to be seen. The alternative could be to keep waiting for something else to popup, or to consider something new, like a Cowboy or Typical Chinese machine... The materials I'm sewing, are 3-4 layers of webbing, leather strapping, multiple layers of canvas and wool with binding, etc. I unfortunately do not think I can afford a newer machine like the Juki 1508. I also have a bunch of binding attachments for my Juki 555, but I have a suspicion none of them will fit the aforementioned walking foot machines, which is a shame! Are attachments for the Pfaff readily available?
  14. Just an update: I ended up getting a mechanic in to look at my machine. He actually got it working reliably by removing bits: We removed the knives, as they were having issues cutting the high tensile nylon bonded thread I'm using. We also removed the lower thread retainer. The mechanic additionally adjusted the bobbin thread, and this made a very visible difference in stitch quality. The machine is now reliably stitching, the only draw back is I need to cut between stitches - no big deal, as I don't run a production factory. Also loosening up the thread on the tensioner improved the stitch - I'm now able to punch through three and even four layers of webbing. Just posting this for any other antiquarians who are interested in getting the Singer 269W / 269W141 going. All in all pretty happy with my $150 bartacker!
  15. What Kind Of Machine Is This?

    Amazing, thanks everyone - such fast replies! Kaplan Sewing link was great, thank you. Has anyone ever worked in high load safety sling sewing? Ie. lifting slings, vehicle lifting slings, etc - and if so, did you work within standards set about by your country? For example, in Australia we have things like the AS/NZS 4380:2001 standards - Cargo restraint systems -Transport webbing and components. Does anyone have any feedback on the reality of working in this kind of industry?
