I have been sewing A LOT. Every Monday I travel to an outreach clinic and there I work with some pretty wonderful women. Yup. All women. I showed off a hand bag I had made and they all want one. So now I am fulfilling my promise. I have five of six done. I used the 237 on Wednesday, yesterday and today. I struggled with it, I admit. While it is useful for zig zag, the stitch doesn't hold a candle to the one produced by the 201. I finally switched back to the 201 tonight after scrutinizing the top stich on the latest bag. I hated it. I took it out and re-stitched it with the 201. Heaven.
The 237 is quiet. And STRONG. The stitch may improve if I switch out the needle plate with one for a straight stitch machine. I believe the 239 is the straight stitch version. I can get the needle plate for it and try it on the the 237. I was using the 1/4 inch quilting foot, which is, in essence, a straight stitch foot. Except that I messed up and put the foot on while the machine was still set for a narrow zig zag. Believe it or not there was room on the foot to allow the zz. Not full width, but still. I should have tried the straight stitch foot. Next time.
I think that the coil spring belt was too big for the 237. The hand wheel kept turning backwards. I did not have that difficulty with the 201 with the large spoke wheel. This created difficulty sewing. I tore out many thread nests. The fabric I was using frays readily and I did use the zig zag on the seams. Interestingly the zig zag was quite lovely but something was just not right about the striaght stitch. I ordered a smaller diameter coil spring belt and a urethane belt from Mc Master Carr today. I expect that later on this week I will have them. Look for a post about the differences between the two. Oh and I guess I will comment on the leather belt too.
All in all I enjoy treadling. I have a bit of a galloping rhythm. I am a one footer, but to increase speed I add my left foot. It isn't really exercise. But I am moving my legs and I am not as stiff at the end of a day of sewing as I am when I use the electric machine. That is a plus for a woman in her seventh decade.
