Denster Posted December 26, 2011 Report Posted December 26, 2011 Mike What you are probably noticing regarding the click and then the extra pressure at the end of the stroke when actually sewing is the cam on the needle bar that raises the thread takeup arm. On the newer machines the thread takeup arm is springloaded to keep a bit of tension on the thread. The click is when on the upstroke the cam hits the thread takeup bar. The extra pressure at the end of the stroke is the bottom loop being pulled into the leather. If you are really feeling it you probably have the bobbin tension set way too tight. Most new users do this. As to the 1lb for setting bobbin tension this is not a precise measurement. Just back off your bobbin tension till the thread flows smoothly with slight resistance when pulled. Quote
mlapaglia Posted December 26, 2011 Author Report Posted December 26, 2011 (edited) I made a video so anyone that wants to can look at the problem I am having. You might have to crank up your volume its not real loud. Hope it gives someone an idea. Its not constant. Its sometimes less and sometimes more. The last 2 cycles show it well.

Denster Posted December 26, 2011 Report Posted December 26, 2011 (edited) OK I watched the video several times. I am presuming you have lubricated the machine? For the most part it sounds and acts just like both of my bosses. A few things I noticed. One that table will never do. Way to much wobble. Second you could probably use about two more complete turns on the presser foot pressure screw. Third you do not have it threaded correctly. The thread should pass in front of the pin that is between the double hole pin below the thread guide and the first tensioner. You have it passing behind it in the video. Regarding the presser foot pressure. It must be enough to hold the material in place as the thread lift bar pulls the stitch into place. If it is not the material will be pulled forward resulting in some bad looking stitches and the inconsistant pull up you are seeing on the thread take up arm. Most folks try to get by with as little pressure as possible to avoind marking the leather and cause themselves all kinds of problems. The marks are easily removed and shouldn't be a concern.

Denster, Yes it was threaded wrong. I know it goes in front but messed up that time. That didnt change the issue. Yours hangs up just about the end of the cycle and needs to be pushed harder to complete the cycle? The thread and bobbin tension seem to be right as I set the bobbin to one lb and the thread sits in the middle of the hole. no showing on the top or bottom like the manual shows when it needs to be adjusted. I have not touched the pressure foot tension at all. It is marking the leather somewhat but I figured Id worry about that later. I will increase it and see if that fixes it. The Table is a temp, its not where the machine will normally be. It just has not arrived yet. One of the reason it wiggles that much is its really hard to finish the cycle on the arm. its not even the same all the time on the same line of stitches. The stitches look good top and bottom its just the grinding sound and the hard push at the end of the cycle that bother me. It doesn't sound like the machine on the video sounds. If the sound was not evident than it was a bad recording. It's there. Thanks for looking at the video and your suggestions Michael Quote The key to immortality is first living a life worth remembering. Bruce Lee
Members oldtimer Posted December 26, 2011 Members Report Posted December 26, 2011 (edited) What causes most problems with the Boss are short strokes. The handle must be pulled to end stops, top and bottom. Also, I have had three Boss machines and they need to be lubricated as they are almost dry from the factory. / Knut Edited December 26, 2011 by oldtimer Quote "The gun fight at the O.K. corral was actually started by two saddlemakers sitting around a bottle of whiskey talking about saddle fitting"...

Thanks for looking at the video and your suggestions Michael It doesn't what I would call hang up it just requires some extra pressure right at the top of the stroke as that is when the cam on the needle shaft pushes the thread takeup lever into final popsition and pulls the loops of thread into the leather. If you don't feel this when dry cycleing the machine but do when sewing then that is what it is. Quote
