- Add holes using the mill at 600 rpm and radial indexer (*Note: add holes 0.3 inches from the side that has the better machine-finish)
- 12 holes equate to 3 1/3 turns for each hole on the 18-radius marker on the radial indexer in N-51
- Safety note: use air gun to blow away fiberglass dust as soon as each hole has been completed.
