Members skipj Posted March 20, 2008 Members Report Posted March 20, 2008 I just got a 4000R and the manual looks the same as the 3000. It is the same manual after further review. Steve told me there is a error in the threading diagram for the 4000, he probably told you about it already, when you thread the aux tension head you are supposed to run the thread back through thread guide "A" again. This is a typo in the manual. I was trying to sew with 346 thread on the needle and the bobbin, that's the thread that came with the machine, and I couldn't get hte thread tension right. The manual says you can use that combo for sheaths but Steve says it won't work which was my experience, the combined thread layers are too big to go thru the hole the needle makes. SkipJ Quote
Contributing Member rdb Posted March 20, 2008 Author Contributing Member Report Posted March 20, 2008 Thanx skip. I wasn't told anything about that aux tension. I'll try that tomorrow, just to see. With the great telephone support from Artisan, it's a wonder Steve or anyone can remember to tell us all everything they know, gawd knows, they try though...lol Quote Web page Facebook
Members tonyc1 Posted March 20, 2008 Members Report Posted March 20, 2008 Hi rdb,With thinner leather and thicker thread, getting the tension perfect can be a problem. It is not absolutely necessary for the lock to be in the exact center of the leather or layers of leather, just in there somewhere, and in older manuals (which seem to be more instructional) it recommends the lock just up a little from the bottom. When I first got my 4000, I filled up 6-10 feet of old Tandy 10oz veg tan with neatly stitched tightly spaced rows. I oiled and adjusted and sewed and tried out things, and basically broke me and the machine in. Not saying I couldn't have done a project, but I think the practice was time well spent, I probably needed it more than the machine. So first things first. Which tension is main and which is aux. I use the tension at the top of the machine as my main tension adjustment. I like to use this one as the presser foot lifter releases it when the foot is lifted. I call this the "top" tension. The lower tension closer to the needle I call the "lower" tension adjustment and I rarely apply much tension here except for double wrapping it. This is my way of doing it, others may be different. Check with Steve at Artisan for the proper tension to adjust. For heavy stitching in veg tan, I use a lube pot with silicone thread lube. Not necessary with lighter threads and leathers, but it seems to smooth things out for me. Remember, with thicker thread on thinner leather, your margin for getting the lock right is a lot smaller, that's why some of us have more than one machine, one set up with a 26 needle (230) needle and 346 thread and one set up with a 20 needle (125) and 138 thread. Art Hi Art. On my 205, I've only ever used the top tensioner to alter tension, the bottom one is just the same as when I got the machine and I use #160 to #230 needles and thread from #20 to #10 and any adjustment I do is very minimal and by doing it this way it is easy to pull the thread out when you lift the foot as the tension relaxes when you lift the foot.

esantoro Posted March 22, 2008 Report Posted March 22, 2008 I get better results when I wrap the top thread 2.5 times around the lower tension discs. ed Quote http://www.waldenbags.com http://www.waldenbags.etsy.com
Members TheArtisan Posted May 15, 2008 Members Report Posted May 15, 2008 (edited) I get better results when I wrap the top thread 2.5 times around the lower tension discs.ed Hi I am new here and bought the toro 3000 for top stitching on my auto upholstery surface seating. I use 415 thread on top and 138 on the bottom. One thing that helped me is that insead of wraping twice around as directed I wraped it once and it turned out really well.

esantoro Posted May 15, 2008 Report Posted May 15, 2008 I have recently gone back to the 1.5 wrap, but I now make sure there is not much drag on the bobbin thread, that it pulls out of the bobbin case very easily. I noticed that with such a setup I can predictably adjust the top tensioner for micro adjustments. I'll have to try 415/207 or 346/207. Otherwise I would have tried going only one size lower for the bobbin, but i suppose it depends on whether the bottom stitching will be seen.

Ed Good point for my type of application the bottom stitch is not seen. I told Jerry to set it up for 415 for me but I do not really think he understook my use for it. I had to try it many different ways before it would even stitch on the thinner leather. Kevin Quote

Sometimes I need to stitch on only one layer of 5/6 oz leather, chrome tan or otherwize. ed Quote http://www.waldenbags.com http://www.waldenbags.etsy.com
esantoro Posted January 16, 2009 Report Posted January 16, 2009 There is something I do, something I stumbled upon, and I've never heard it suggested by anyone. I have removed the spring from the bobbin case, so now only the tension screw adds tension not the spring pushing the bobbin against the shuttle casing. This isn't necessary if you only stitch thicker leathers, but if you traverse a range of thicknesses on a single project, I think the removal of this spring is a good choice. Another thing I do with lighter leathers is use a slotted, feeddogless needle plate. It removes the feeddog as an agent in conveying the leather but the result is better stitches, though you do have to pay a bit more attention to applying a little nudge to keep the leather moving slowly, depending on thickness, speed, etc. A few weeks ago and other variables. A couple weeks ago I went back to the standard needle plate with feeddog adjusted lower. After more tests, especially with 346 thread, I went back to the slotted plate. Ed Spoke with Steve at Artisan....Good Man!It was actually not something I or the machine did that was wrong. The 3000 comes shipped with a 25 needle and 277 thread. The combination is perfect for 3/8 and above leathers. What I had been attempting even with two layers fell within the 1/4 inch zone. Depending on the type of leather, the climate, and quark resistance this becomes a grey zone for the needle and thread mentioned above. Steve's recommendation was to use a 24 needle, and go for 207 thread on the bobbin for this 1/4 inch depth. Well, I don't have either the 24 or the 207 right here, but we talked a bit further, and Steve explained how to begin the setup on tension. I'll repeat it here for any other wayward warriors.... Loosen both the upper (aux) and lower (main) tension screws until they no longer touch the spring (just before they fall off actually) then tighten enough to just touch the spring again. Sew a few scraps. I did that and found the knot almost on the bottom of the leather, so...according to manual, you tighten incrementally until the knot appears right. I did that, and it worked right fine on the 1/4 inches. Thanx to Luke and Art for trying to help out. That's why this place is the best on the net!! I'm still gonna have to go find that old lady to help across the street, even if she don't want to go....LOL Quote http://www.waldenbags.com http://www.waldenbags.etsy.com
Henry Posted January 16, 2009 Report Posted January 16, 2009 rdb, I ran into the same issue. After trying everything the manual indicated and some of my own ideas, I re wound a bobbin and re threaded the machine following the exact diagram in the manual. Turns out that no matter how many times I looked I had threaded it wrong in one spot. Also make sure your needle is sharp and inserted the correct way and depth. Hey, I like the buckle you used, can you tell me where I can buy some? Thanks, Henry Quote
