Every Craft attempt is defined by two elements: the time required and the difficulty. The materials qualities can vary the difficulty.
Very Simple: These items are more or less all one piece or one material of simple shape with no moving parts. Examples: crowbar, quarterstaff.
Simple: A simple item is largely made of one material, but it requires a more specialized shape. Examples: many simple weapons, backpack, most common articles of clothing, simple traps such as pits.
Moderate: Moderate complexity items are characterized by diverse materials or different parts that must be integrated into a whole. Examples: Most weapons, bows, all shields, locks, simple traps using simple mechanical triggers.
Complex: Complex items have diverse materials, moving parts, different parts, and/or decorative bits. Examples: Most types of armor, Composite bows, crossbows, and most vehicles (excluding large ocean-going vessels).
Very Complex: These are the most complicated items. They require diverse materials, moving parts, different parts, decorated bits, and/or multiple functions or uses. Examples: ocean-going vessels, unusual armors (such as barding).
Complexity Time Unit Base Maneuver Diff.
Very Simple 8 hours Routine
Simple 2 days Light
Moderate 4 days Medium
Complex 1 week Hard
Very Complex 2+ weeks Very Hard
In attachment the Craft tables and my Equipment list revisited (sorry lot of entries are in french i'm too lazy to translate back to english)
I have used this system with the Magical item creation too adapted from the original rules, with a "normal" pricing.
As i'm converting the Pathfinder AP to RM or HARP now, i'm playing in a High Fantasy magic setting. So the prices for common low magical items are more affordable.
