Yesterday I was asked by the manager at our local Restore to take a look at a Featherweight that had been donated. She said that it did not work. I brought it home and today started cleaning, oiling and greasing. There was thread wound around the bobbin housing and the belt was too loose. Got the thread out and put my Featherweight belt on and it runs just fine. It does make a noise from the motor, not very loud, but mine doesn't make any noise. Don't know anything about motors but I know you all do (Joe). I also have a question about the Tri-Flow grease. I know many of you use the Tri-Flow oil, but what about the grease. The Singer 1/2oz. tube is $3.19. The Tri-Flow 3 oz. tube is $10.75. Do the math, the Singer grease would be $19.14 for 3 ozs. Need your advice on whether to buy the cheaper one. Here are some pics of my Featherweight (Centennial) serial no. AK599635. I got it in 1959 when I was 18 years old. The first thing I made was slipcovers and curtains. The Restore 1951 Featherweight serial no. EG710143. Light switch knob is broken off on Restore machine. Mine with knob is on the right. Have you ever replaced one of these? I am waiting to hear from SewClassics on this.Restore machine on left, mine on the right.The last three pics show the feet. Mine on the left picture are round and have been on the machine since the fifties. The ones on the right are flat, look like they melted. I am trying to chip the old stuff off, but it isn't easy. Will order replacements if I can get the screws out. Thanks for any comments or suggestions. I value your opinions and am so glad I finally mastered posting pics so I can share with you all. Have really enjoyed see all of your pics for the past 2 and 1/2 years and learning to love vintage machines.
