how to correctly insert the bobbin case Brother's VX-807

Is this a drop-in or front loading machine?

The site below does not list the VX-807, but has the threading diagram (including the bobbin case, scroll down to the bottom of the page) for the VX-808:

I will assume you took apart the entire shuttle assembly. Raise the needle to the highest position. Then fist insert the shuttle, the half moon shaped piece with the beak on it, beak goes down. It helps if you tip the machine back a little so it does not fall out. The 2 black levers should be pointing away from the center at about 10 and 2 Put the ring on and move the lever toward the center to clip them on the race ring. Place the bobbin in the bobbin case so then you pull the thread the bobbin turns counter clockwise. Place the bobbin case on the pin on the shuttle with the finger positioned so that it fits in the slot in the race ring (just before 12 o'clock) Be sure it snaps into place. you will hear an audible click

Hey, that sounds EXACTLY like my White machine, circa 1975. Are hey cousins??

It a standard oscillating shuttle machine. Perhaps the most common shuttle type ever made.

This was the most helpful explanation!! thank you!!!
