Another Ferdco Question

[daman1974]

So I got my bobbin case finally. But now it seems like the tension is too tight on the string feeding down to the needle. How tight is that supposed to be?  I looked at my wife’s machine and she has numbers and what not on hers. So I am going to have to go by feel I guess.

You might look at youtube, look up threading a 441 machine...

The top tension is always greater then the bobbin tension on a lockstitch machine. If you want less top tension, back off the bobbin spring until it requires a minimum pull. I do this when sewing soft things, like chaps, or hemming pants. Backing off the tensions results in a lighter lay of the thread on both sides. This is good for items that flex a lot. It's not good for holsters, sheaths or hard cases.
