I have an elna airelectronic tsp sewing machine & cannot thread the bobbin
Firstly, have you got an Elna metal bobbin? it should be solid on the bottom and have 7 holes on top. It is essential that you always use it this way, wind it with the holes on top and load it into the bobbin holder the same way.
Have a look at the image above, you need to load the bobbin in and click the thread into the tension spring so it doesn't lift back out when you pull the thread upwards. There should be an audible click as it goes in.
If you can't get it right or this image is just too small, feel free to email me and I'll send you the image and talk you through it, I have a TSP machine too. [email protected].
Also, check my tip on bobbin winding here http://www.fixya.com/support/r10598580-winding_bobbin_correctly it is important to get a good even tension onto your bobbin as you wind the thread on, you may need to manually add some tension to the thread as it winds off the spool, as I've described in my tip. I sold these machines for Elna and customers would bring them in complaining of problems with their machine. Almost aways, it was the needle in backwards, bobbin upside down, thread/lint buildup in the bobbin race or badly wound bobbin that was the problem.
Hope this helps you Gaylene, but if not, please email, I may be able to send you the relevant manual pages.

Wind the Bobbin
For the usual jobs, it is the best to use a medium sized thread.
2. Disengage the flywheel by unscrewing the coupling knob as far as it will go.
3. Place the bobbin on the bobbin winder, and push the bobbin winder to the right.
4. Pull out one of the spool pins and place the spool of thread on it.
5. Pass the thread through the bobbin winder tension discs, as indicated.
6. Wind the end of the thread around the bobbin by hand, in the direction indicated.
7. Wind the bobbin, at a medium speed by pressing lightly with a finger on the spool so as to stretch the thread better and thus fill the bobbin to a maximum. The full bobbin stops automatically.
8. Re-engage the flywheel by tightening the coupling knob.
9. Cut the thread and remove the bobbin from the bobbin winder by pushing the latter to the left.

it sounds like the needle hook timing is out. You need to get the needle in the lowest position and measure the gap from the needle to the hook point on the bobbin shuttle. It should be 1/4". You will need to remove the foot and foot plate to be able to see. I use a 1/4" drill bit as a gauge. If you need to adjust it, you will need to remove the free arm cover to the right of the foot and loosen the 2 allen head screws that hold the drive gear. Adjust the gap, tighten the screws and retry. Usually if the needle catches the thread to early, it will make a bad stitch and the upper thread will break. If it catches to late, it will make thread loops and the machine will skip stitches. Good luck, these are a good machine and worth fixing. Phil
SOURCE: Singer Sewing Machine model 9224. Bobbin thread
If you turn the handwheel, can you see a metal ring rotating around the outer edge of the bobbin case? If not rotating, broken gear or timing belt off.
If that ring is turning, remove the needle plate and bobbin case. As this ring now rotates, you will a finger on the ring that will pass behind the needle from right to left and it should catch the thread from the eye of the needle. If this finger, the "hook" passes above the eye, you have a timing problem.
Let me know.
