Bobbin Hook Timing On Twin Needle Singer

[MuddyClearWaters]

I have a Singer 52W19 post bed Twin needle with wheel foot. I bought it with 3/16 spacing. I changed it to 1/8th successfully. I've now got lost trying to change it back. It's been a nightmare so far. I've sunk 10 hours into trying to get the right bobbin to work. I've got it to work a few times on thicker harder leathers I have (5oz). However as soon as I switch to something thinner 2-3oz the right side goes to shit. If anyone has any experience timing and adjusting the bobbins on these machines, It would keep me from throwing it out out the window.

Thanks

With the needle bar all the way down,the point of the hook on the right side should be @ approx. 7:00 position.Or if you drew a line from the center of the bobbincase to the front throat plate screw the point should be right under it(with the needlebar all the way down)Then you can set the spacing as of the hook as close to the needles as you can get & then make sure the needles are set so the top of the eye is a good 1/16 of an in below the hook point as it meets the needle.

So I've consulted the manual for this machine. It says the timing should be adjusted as such. After the needle bar has traveled all the way down. Raise it 3/16" or to the indicator mark on the needle bar (there is no mark on my machine) then the bobbin hook should be centered on the eyelet of the needle 1/16" above. This is how the Left needle and bobbin are spaced and it works fine about 95% of the time. I've attempted to match the same timing and have got them in dam near identical yet they still don't work. I've pushed the right bobbin so close to the needle that in the full down position it's resting against the side of the lower portion of the bobbin. Any further away It won't grab the thread. Any closer and the bobbin case just pushes the needles over and farther away from the hook.

Another note I might point out is the right bobbin is a little more worn than the other, the hook is dulled slightly, I don't know if thats a critical issue. I would assume no since It worked fine in the 1/8" setting.

3/16" is to much try 3/32"
