Editing Pivot System (section)

=====By Hand=====

If you have no lapping tools, you will have to lap the bushing by hand. Start by placing your bushing flat-side-down on your lapping surface and lap the bushing in a circular or figure-eight motion while applying even and constant pressure across the whole bushing. After a few motions, usually between 3 and 10 (in this example we will use 5), '''but always keep the number of motions the same''', rotate the bushing 90 degrees. Repeat this process three more times. In total you should have performed 4 rotations (ending back at your original position) and 20 circles or figure-eights (5 per rotation). This completes one pass. 

After you have completed one pass, you should [[#Strop]] the bushing. Use the exact same technique as described above, but with stropping, you do not have to follow the steps as precisely because stropping removes little to no material. After that, you should check if your bushing is uneven and make it even again as described here: [[#Uneven_Bushing]].

Check the tolerances as described in this chapter: [[#Checking_Tolerances|Checking Tolerances]] and repeat as needed.
