My granddaughter found this Dressmaker Model 3000 on Freecycle. Yes, it was free. She brought it over for me to clean and oil. I discovered that the tension assembly dial was loose. It actually came out in my hand. Uh Oh. Got to think this one out. I noticed that there was what appeared to be a set screw hole on the inside and opposite it on the outside of the piller was a hole with a very small set screw. So, I replaced the tension assembly in the position that I figured would be best, tightened the set screw and test drove her. Well, it worked. She is a basic zig zag machine and sews a perfect stitch with perfect tension. My GD has named her Jocylyn. Oh no, does that mean that she has been bitten by the VINTAGE BUG????
