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.
@Phillip_Ma has kindly offered to try printing this part in resin for the sewing committee which wil make the part stronger. No guarantees but we’ll report back. If that doesn’t work FDM printing is still a possible option.
Phil has printed the part for this which is fantastic - thanks!! It’s at the space and likely needs a little light sanding before being installed. Mark has offered to install the part if someone (maybe sewing committee?) can sand it.
Note that these Spool Thread caps were always the wrong size for the Brother Sewing Machine.
These do not fit this particular pin. Its easy enough to 3D print new caps.
