How to thread a Japanese Class 15 bobbin

Japanese Class 15 "clone"

If you've already read "Bobbin Case Basics" you won't be surprised by anything you read here.  But you may find it helpful if you own one of the many Singer 15 "clones" built in Japan.  


Japanese 15 clones use the same bobbin as the Singer 15 machines, but the bobbin case is set up backwards.  The flat tension spring is on the opposite side, which means the thread wraps in the opposite direction when you insert the bobbin in the case.  

However the basic principle of bobbin loading is the same whether you are loading a Singer 15 or a Japanese 15 bobbin: the thread slides under the tension spring in the opposite direction that it wraps on the bobbin.

1.  Hold bobbin case in left hand with open side facing right and slotted groove pointing toward you.  
2.  Hold bobbin in right hand with thread wrapping AWAY from you over the top of the bobbin.  
3.  Insert bobbin into case with a right to left motion. 
4.  Pull thread into the slotted groove.  
5.  Slide thread TOWARD you and DOWN along the tension spring until thread pops into notch at the bottom.  
6.  Load bobbin into machine. 

There, wasn't that easy?
