Hello JustAbitCrazy

The reason a long bobbin machine makes a rattle is because with every stitch a loop of thread is made and the shuttle goes through the loop, so each stitch causes the shuttle to make a tiny jump in its carriage.

There is absolutely no reason why you should give up looking at long bobbin machines thinking they are noisy. It is just that they make a different noise to round bobbin machines.

If you want to hear what long bobbin machines sound like you can watch my Youtube videos (link below), in particular "How to Treadle"

And no, I don't find long bobbin machines temperamental.
