Thread Binding Techsew 2700

[zoomer56]

Received a Techies 2700 yesterday, yay. Ron set it up for 138 size thread and 135x17 22 needle. He left a roll of the white thread up top and I sewed it all up with no problems. I changed to black bonded polyester size 138 thread (although my thread seemed almost half the size left in the machine). I threaded and installed bobbin also with same black thread. Worked fine. Now not. When I sew some, put needle at top, raise the foot and pull the work out a nest is attached. I rebobbined and watched the first cycle that should pull up the bobbin thread. See pic, the cycle is almost done and you can see that two pieces of thread will get bound in that small opening between hook assembly and dog holder. So I started over, this time threading the bobbin thread under the dog holder. This time the top thread comes around and only the one thread has to squeeeeeze between hook assembly and dog holder. Seems ok. Now, with cover off so I can watch the action all seems to be ok and sewing looks good. With the cover on, it seems like the looping action of the top thread is now binding on that little gap between hook assembly and dog holder. Maybe the cover is causing the thread to get tweaked enough that it may be twisted an has a hard time getting through that gap to complete the cycle.

The video on Techsew website is it at just the wrong angle and does not show the bobbin thread going thru that gap on the left side. Should it?

Should it be hard for the thread to get through that gap?

Can thread twist with cover on making it hard to get through that gap?

Ideas . . .

thank you,

Robert

Be one with your machine.

This is my first machine. I like it.

I believe thread size 138 is probably the limit for the bobbin. I have only layed down about 50 lines of thread but have gained a good feel for the machine.

The gap between the hook assembly and dog house is just enough for thread size 138 but is a tight squeeze. I have also figured out how to load the bobbin an pull the bobbin thread through to the top. It requires me to thread the bobbin thread under the gap instead of trying to pull it through with a tug.

So all is sewing just fine now.

How easy is it for you to pull your leather off machine when you're finished sewing ? My tension release does not work when I have the pressserfoot up . I was wondering if anybody else with same machine had same problem. I windup rethreading the machine all the time because I have to cut the thread close in order to remove project.

Reach up by the take up leaver and pull some slack in your tread then cut your thread and you wont have to rethread.

The 2700 has a tension release pin. You should not have to pull the top thread by hand, unless the beehive spring is set too tight and the links can't compress. If the spring is that tight, back it off until the disks are able to separate. Then back off the bobbin spring tension to balance the knots.

Looking at the top disks you can see some action (tension release) as the presser foot is lifted up. I am able to pull the material out. It is not without some tension but acceptable.

First project for new machine. This is a seat back for a sport car.

Nice seat!

[Colt W Knight]

Excellent seat. Is there a trick to running all those long a parallel stitch lines?
