Rotary Primer System Overview
Warning: Wear safety glasses whenever working with live primers.
Observe how the rotary primer
system works, how to charge it and how to seat a primer. To do so:
1. Put on your safety glasses.
2. Place five or six primers into the primer magazine
shiny side down Figure 129.
3. Cycle the machine until a primer appears in Station two.
When you cycle the machine, the rotary primer disc rotates one notch, advancing
another primer into position. When the handle is pushed to its full aft stop Figure 131, the primer seating punch pushes the primer up through the
rotary primer disc Figure 130, fully inserting it onto the primer
pocket of the case. If there is no case in Station 2 to receive the primer, the
primer will return to the rotary disc and continue around until being dropped down a chute
Figure 132 where it can be retrieved.
4. Drop an unprimed case into the casefeed funnel and cycle the
machine twice. As the case is rotated into Station 2, complete the downstroke of the
platform by firmly pushing the handle to its full aft stop Figure 131 -
this will ensure that the primer is fully seated.
5. Set aside the primed case, it will be used later for adjusting the
powder measure.
