Earlier this week I asked for help to sort out my frends machine. Thank You to those who gave me suggestions. Kampfzwerg gave me a link to a You Tube Video. I looked at it and then passed it over. Eventually I gave up. Suddenly the bobbin in my machine was squeaking. It annoyed me and then I thought of the You Tube Video. Asin the Video I put a small amount of oil on a tissue and wiped it under the bobbin case and also inside the bobbin case and then wiped it away with a clean tissue. No more squeaking. Last night again I thought of my friends machine so did the same. WOW! this machine now works a treat. I was so excited that I messaged her right away. Just shows what a little Oil does do wonders. Thank You Kampfzwerg for the hint.
