thanks for getting back to me. After playing with the machine I think it is unlikely it is bent. Tried the same cordura and thread on my horizontal bobbin singer and it did a sightly better job. I'm thinking I'm just asking too much with such a heavy thread and only two thin layers of fabric I would still like to know how to time the belt and pulleys, though

Thank You! I wish I could find a service manual, but no luck. I am wondering if possibly the takeup arm is slightly bent down?

I have a Mitsubishi Du 105 that I assume is a clone of a singer 211 series. Generally it sews far better than I do, but it seems to require an enormously high top tension to center the knot with minimal bobbin tension on thin materials. On thicker material (8 layers of cordura) it seems less critical. I am not sure the thread take up(I think that's what its called) is setting the knot fully and would like to check the timing between it and the supposed marks on the lower main-shaft. I can't find any marks, can I use some other position Indicator? like hook position the check timing? Or can someone familiar with this machine tell me where the marks are? Thanks In Advance Wayne Overbeck

Somewhere I saw .032 vertical clearance I put in a new Hook/bobbin basket and now the basket does not bounce around at all. this new hook assembly has less clearance for the basket to bounce around. But, it still seems to take WAY too much top tension to seat the stitch. Damm, I wish I knew what I'm doing.

Eric, thank you for the input, It is currently adjusted to rotate the bobbin basket ever so slightly so as to center the tab in the groove in the throat plate. even after playing with the opener adjustment, It still is not pulling the thread "cleanly" over that tab. the basket seems to get jarred 2 times during the take up of thread. It looks to me like after the thread finally gets between the tab and the throat plate, it trys to hang again at the trailing end of the part that secures the basket with two small screws. Yesterday I slightly raised the hook/basket/bobbin to .030 vertical clearance because I saw that spec somewhere for a Singer, it was about .045 probably made things worse but I was wondering if the tab was so low that it was trying to wedge under the throat plate and pinch the thread, but no luck. I can go back and drop the hook to the .045 vertical clearance position and play with the opener some more. Thanks Wayne

Well I changed the timing, and repositioned the needle bar but started tearing the upper thread, so I put it back. Loosened up the top tension and I have to say the thread moves smoothly over the bobbin / hook, but a small loop still hangs on the bobbin carrier for a fraction of a second as the take up is almost fully up. I think this snagging is what is causing the problem. how tight should the bobbin carrier fit in the hook? Mine has maybe .025 radial clearance, the hook itself is tight in it's bushing Thanks

OK, I will try that, I assume advance the lower unit? Normally can one fudge the belt towards the edge of the lower pulley, or is there a better way? Thanks!

I have a Mitsubishi DU-105 that I can't find a manual for anywhere. It has triple feed and looks like a 211 walking foot machine....kinda. It sews very nicely on 4 - 8 layers of sunbrella, but when trying to sew 2 layers, the bobbin thread just lays along the bottom of the material, not pulled up at all. Under all conditions, I must run massive top tension to bury the bottom thread, and the bobbing carrier makes a violent movement as the thread pulls free from the bottom needle side of the bobbin carrier( I think this binding makes it act like bobbin tension is too high) I have the bobbin tension set so low you can pull it with no effort at all. Anyway, looking at the bobbin carrier/hook it appears the take up lever is taking up too soon, when the hook has pulled the top thread half way around the bobbin carrier, thread is drum tight, and the machine is difficult to turn using the handwheel, the thread then fully slides away from the hook and then slightly hangs on the bobbin carrier and the hook at the tail end of the plate that holds the bobbin carrier in the hook. I can't find any timing marks and there are no marks on the needle bar. Wondering about advancing the hook so the thread will be past the tightest point before the takeup lever really pulls hard on it/ Anyone have any suggestions? Wayne

I just picked up this machine to supplement? my Singer 119-3 and I can't find a manual anywhere. Is this thought to be a copy of a Singer 211XXXX? Would like to know about several buttons on it including the one on the top and general specs would be nice also. Thanks in advance
