Fixing the timing issue looked not too bad so I had a look at the Brother NS 80 sewing machine today to see if I could fix the bobbin thread timing issue.
After taking off the case there’s the machine in all it’s basic glory.
I popped this belt off the gears to manually set the bobbin so that it meets the hook at the correct spot and also verifying that the presser foot is in the right place. i.e. down when the needle is down.
Great job fixing the timing!!! That was quite the disassembly process!!! If we can find the exact thread spool holder part online I’m happy to print it.
