Part 2 of the timing series. How to check your sewing machine’s hook timing. This is a simple check that I have heard of shops charging money for. Once you’ve done it a couple of times, it can be done in 30 seconds or less. Hopefully, after reading this, you’ll never pay for someone to check your timing again.
On a properly timed machine, when the needle is down, the hook is just about behind the eye of the needle, but not quite. To be timed right, the needle will be on its upswing as the hook ends up behind the eye to catch the needle thread.
This goes back to what I talked about in the last post: Excuse me, do you have the time? When the needle is on the down swing, the thread is tight against the needle. As it begins to swing up, the thread bows away from the needle, forming a loop.
This is when the hook needs to come along and grab the thread. At any other time, the hook will not grab the thread, and worse, more than likely the needle is going to collide with the hook assembly.
