I now have two treadles that can be set down to and used without having to move anything (I hope). They are a Singer 319W, and a Singer 306W24. I will be swapping the 306 out with other standard-sized Singers as needed, since I won’t need both the 319 and the 306 zigzag machines setup at the same time anyway, and the 319 has built-in cams. About the only zz stitches that I ever use is a regular zz and a multi-zigzag, and they’re both in the 319. A third treadle, a Singer 27K2, is also set ready nearby to use by the wife when her power goes out and she needs a straight-stitch quilt block piecing machine. She got to use it earlier this Spring.
