Thanks so much. The machine I'm wanting to try this on is an 1899 Singer Model 27. At least that's what Charlee said she thought it would be. I still have a stuck stitch regulator but everything else is working well. And I'll keep working on her till she's feeling healthy again..... she's getting better every day. Since I learned on a treadle machine so many years ago she'll be a fun memory back. Thanks again, Jean (nanna-up-north)
