Top View of the miniSpinner  

This is another view with the flyer and bobbin assembly removed.  You can see the large sealed ball bearing at the orifice end on the left, the other bits shown in previous pages, and the self-aligning bearing at the right for the bobbin end of the flyer.  

Again, no lubrication is necessary or desired (you don't want a bunch of dirty oil messing up your nice, new miniSpinner, do you?)

To change bobbins, you simply open the latch, fold the back down as shown, and slide the bobbin off the flyer shaft (flyer not shown in this photo).
