How many separate joints to clamp
How We Calculate This
Calculates the number of clamps needed based on joint length and recommended spacing for your assembly type.
Formula
- Clamps per join = Part length / Clamp spacing + 1
- Total clamps = Clamps per join x Number of joins
- Spacing: 30mm (fuselage), 35mm (hull), 40mm (wing), 50mm (structure)
