I had a local serviceman check, clean, oil, and unfreeze my selector knobs. I am running now and it works. It is still a bit sluggish, but I think that is because it has been sitting so long and needs to be broken in again. He did a good job fixing the problems, cleaning--- well, could have been better, but it works.
I used to do all of my quilting when I had my first 401A in the late 50's and 60's. My D1 is too fast for me and takes off without me half of the time and I have been taking my quilts to a lady with a long arm. Now that I have my 401, I'll try again quilting my quilt, at least the latest one, a CW 80 x 80. Hopefully I can remember how to do it, although I have used some scraps and tried it. It worked fine.
Now if I can just get my DH to finish the cabinet. He insists he wants to glue some of the wood on the side and finish it himself. I was willing to just polish it and let it go. So now my dear cabinet sits upside down until he gets a round to it. bah=hum-bug.
