Midnight Repairman

No he doesn't exist and I am not it. Last night at midnight my sewing machine was skipping stitches sooo bad and the check spring was broken again. So, I decided to fix it. The repairman showed me how last time he was here because I was prone to this. Well, I think I forgot something because I can't get it back together and I couldn't call him, after all, it was by then about 1 am. I am waiting for him to return my call this am, because I still have a ton of work to do before I have to empty out my sewing room next week. That is another story.
