    nice, fast, no bs, explanation. thx would have been nice to get a bit into some common adjustment problems that these machines have

    Noted. I made these a long while back... and totally missed the comments... as my kids sometimes use my account at home and I have forgotten to come back and check up! I will try to make another one with adjustments only.

    You did not mention if you have previously sown with the machine or this is your first attempt at using it. My assumption is that the needle is correctly inserted, and that the top thread is correctly threaded from the reel through the machine to the needle eye. Also, the bobbin is correctly wound and inserted in the shuttle so that it rotates counterclockwise when the thread is pulled. If this assumption is correct, there are two likely reasons for the needle and top thread not to pick up the bottom thread. 1. The needle position at the point of maximum downward stroke. 2. The timing of the shuttle carrier (This carries the shuttle and bobbin). Needle position Before the next step NOTE the position of the handwheel (12 o’clock) and the shuttle carrier (the tongue or side piece will be at 3 o’clock) Take out the bobbin, shuttle, and shuttle carrier (the piece with the gear/pinion on the underside). Turn the hand wheel clockwise until the needle is at its lowest position (handwheel at 3 o’clock). At this position, the top of the needle eye should be level with the bottom of the recess that shuttle carrier sits in. This can be difficult to see. A good light and even a magnifier may be helpful. If the needle eye is higher than this, drop the needle shaft lower. This is done by first locating the connection link at the top of the needle shaft. You will see a screw that passes through the pivot. This screw locks the link to the needle shaft. Slacken this screw and move the needle shaft down to so that the needle eye is in the correct position. Tighten the screw, but before doing so make sure that the needle shaft has not rotated. The needle eye needs to face along the bed or arm of the machine. The maximum downward position of the needle is important as it is part of the movement that forms a loop in the thread that the shuttle hook picks up. If the needle eye is too high, a satisfactory loop is not formed, and may cause the thread to jam between the shuttle and shuttle wall. Re-assemble the shuttle carrier in the original position. It may be necessary to slight “rock” the handwheel until the gear/pinion on the shuttle carrier engages with the rack. then insert the shuttle with bobbin. Now thread the needle and go through the routine for picking up the bobbin thread. Pull 2-3 inches (50-70mm) of thread from the bobbin, lie it in the groove on the side of the shuttle well, close the top plate/gate. Then rotate the handwheel. If the timing of the shuttle movement is correct, the bobbin thread will be collected by the top thread. Assuming that the needle eye position is now in the correct position at maximum stroke, if the bobbin thread is not being picked up the problem is now likely to be the timing or position of the shuttle. Timing or position of the Shuttle Carrier To check the timing, open the bobbin cover plate and look down on the shuttle and shuttle carrier. NOTE it is preferable that the needle is not threaded for this check. Rotate the handwheel to the 9 o’clock position. Be accurate with this position. Then visually note the position of the shuttle carrier. You are looking to see if the upright edge of the shuttle carrier is just covering the needle slot. This setting is critical to the functioning of the machine. There is a little latitude in this setting but not more than just beginning to cover the slot to almost fully covering the slot. A wrong position can lead to the hook not picking up the bobbin thread, or the top thread being trapped below the shuttle and breaking. The rotational position of the shuttle is adjusted by slackening the two nuts on the bar that moves the rack, which rotates the shuttle carrier. Once the nuts are loosened, the bar can be moved laterally. The bar only needs moving slightly (either way) to rotate the shuttle carrier to the correct position. Re-tighten the nuts, then rotate the handwheel a couple of times. Re-check the alignment of the shuttle carrier with the needle slot. Re-adjust if necessary. You may need to do this a few time to get it right! When the alignment is correct, the hook on the shuttle will pass through the loop formed by the needle. Now repeat the routine for picking up the bobbin thread. If the needle stroke position is now correct and the shuttle carrier aligns with the needle slot, the machine should collect the bobbin thread, and importantly, sew without breaking the thread … assuming the threading and tensions are correct. I hope this is helpful. Trick to explain in words. Sketches would be easier to understand.

    @@johncollins2452 thanks for the details. My machine works but we are going to take apart the insides to make sure they are clean of grit and clean them up a little. This will help me make sure I get things put back together. Unfortunately KZread won't let me bookmark your comment or copy the text for future reference. I hope I can remember where to come back to.
