I thought that, too. But one day, I looked at my machine when the presser foot was off, and lo and behold, there is a third feed dog right under the presser foot. My FW has it as well as my White and my Bernina. My Singer 301 does not, but that is not a zig-zag, and sews beautifully.
{Quote from Krisgray} Prefer to piece on my featherweight and other old straight-stitch-only machines. Since it is straight stitch only the feed dogs are closer together and the fabric feeds more evenly under the needle. {Quote}
I feel this way, too. The old single stitch machines seem to make better seam. I have a piece of moleskin on my FW to show the 1/4 inch seam, as it has that 1/8 foot on the right side.
