Pffaf industrial machine trouble
My son is trying to install zippers in a covering for the wing of an airplane. He is using the company’s Pfaff industrial sewing machine. He is having trouble with the machine skipping stitches and called me for help. I suggested it might be a tension problem, the machine not threaded correctly or the wrong size needle. He sent me a picture of the needle pack he is using. I have never seen this make but is this a size 10 needle like it seems to be? He is using upholstery thread and if this is a size 10 needle, I think it is too small
