Please help, thread is too tight when pass bobbin

[Orrrmygod]

Hi Guys, I'm very new to a leather sewing machine and need some help.

Please see the attached movie (and turn the sound on). I think the thread is too tight when passing bobbin. I think it makes my stitch inconsistent as it's too much force during that time.

Can you recommend how to fix this problem, please?

Thanks

Hi Guys,

I've read the previous post and I think this might be the problem, see attached.

Thanks Mikesc, but now is a bigger problem, the thing that spins around the bobbin (Sewing hook?) is now not moved anymore.

I rethreaded the machine and did some test but there's some thread stuck at the bottom after that, so I tried to cut and pull them out.

I tried to take the bobbin out to check but can't see anything. I'm not sure if the cog at the bottom is the problem.

Yes there is probably thread caught around the base of the hook ( where you cannot see it )..you can take the bobbin out, but do not try to take the hook out, because you'll likely damage it or lose some tiny parts..It is always better not to cut off thread when it is caught around the base of the hook, because when you "cut" you probably didn't get all the threads and now you have nothing to "pull" the remaining thread parts by..

You can try "rotating the hook backwards and forwards very very slightly" ( with no needle in the machine ) by hand( not with the motor, switch the motor off and pull out the plug from the wall ) usually ( if the bobbin is removed you will see that there are some openings in the base of the Hook ) with a wooden toothpick or a fine "crotchet hook" ( a sort of needle shaped tool , with a tiny hooked end, for making things with crotchet) you can see if you can tease out any ends of threads so as to get enough of the thread end and be able to pull on it with tweezers..
If you go carefully, you'll not break anything..

Or..you can take the machine to a sewing machine mechanic..or get one to come to you..

Thread caught around the hook base is an easy "fix" , if one has a bit of experience with sewing machines..for a beginner..not so much..

If the hook stopped turning it's because you popped a safety clutch with the thread jam. You will have to use tweezers to pull out whatever thread is inside the hook. Then once cleared, find a button on the bed of the machine, hold it down and rotate the hand wheel until the clutch tang re-engages the hook drive shaft.

Nice catch Wiz :) It has been so long since I "popped a safety clutch"..I forgot that reason entirely ..

I took the bobbin out and yesterday and nearly take the hook out but I’m afraid that I cannot put it back again so I didn’t. 

Where is the botton on the bed of machine? Inside the hook plate? Could you explain a bit more detail please? Thanks

Is there such a thing as that ' little Post ' being a blame for ..." my machine not sewing correct" ?
Just now, I just went out and checked after seeing this Thread Post . I walked out to shop and looked at an old 211 singer that I have sewed with for 20+ years .
The old 211, The R-side thread tension has that 'post' like in your pic. of that machine . and The L-side has no 'post' on tension mechanism .
So 2 tension spring-discs, with 1 being routed over the post, and 1 not . The R-side thread has always been routed that way ( over the little post ) for all these years of sewing and it sews like a dream  ?

Look at the bed of the machine, to the right of the sliding bobbin cover plate. There should be a push button barely sticking out of the flat bed, somewhere in line with the hook shaft. Use a finger to push it down as you crank the hand wheel. Once it  finds the correct position it will click in and drive the (cleared) hook again.

The mechanism is under the bed, but the button is accessed from the top.
