Question

i need to find out how to thread the bottom half where the spool goes

Answer 1

Mostly your spool fits into a case.
I can not explain which way it should turn.
But if the tension of the machine is off, just take it out and fit it in the other way round.

If you can not find instructions, you can go to this site and request them to put your singer on too:

Answer 2

Insert a wound bobbin into the machine, if necessary, and close the throat plate. A few inches of bobbin thread should be pulled out to the right and sticking out from under the closed throat plate.

Take hold of the thread that has been threaded through the machine needle.

Rotate the handwheel toward you until the needle disappears into the bobbin case.

Keep holding on to the thread and move the handwheel so the needle is once again at its highest position. As the needle rises, a loop of bobbin thread will come up as well.

Pull the thread out toward your left to draw the bobbin thread loop further out of the bobbin case.

Let the top thread go and pull the bobbin thread up until the end comes up. Pull the top and bottom threads under the presser foot and to the back and right of the machine.
