The Desired Level of Parting Quality, Tool Maintenance, and Tooling Life. Trade-Offs Will Be All-Most Decisions, and All Will Affect TOOLING COSTS.

Forms, A Significant Amount of Lift is Needed. External Stock Lifters Carrying The Ladder Strip Work Well in High-Lift Situations.
FIGURE 3: One Side of the Strip Is used to carry this part through a progressive die.
How parts are carried in the strip affects How well the die feeds, the Ability to live the strip for feeding, and the Ability to Produce Consistentant-Quality Parts.

Slightly Out of Adjustment. If a pilot is located in the scrap or the carrier, slight elongation is acceptable, as a long as the piece part dimensions remain with tolerance.
Galling of the pilots. The best solution is to guide the stripper and place the pilots in the stripper.
