Drum library
ref spacing drums use lug hole spacing from the Vintage Drum Reference lug table. Everything else is a typical estimate. Measure your shell before cutting.
Shell
Measure the bare shell (wrap and hardware off). Fractions like 11 15/16 work.
Hardware holes
| On | Name | Sets | Start ° | Step ° | Y from | Y offset | Rows | Cols | Pitch Y | Pitch X | Hole Ø |
|---|
Sets = how many lugs or brackets go around the shell, starting at Start° and repeating every Step° (blank = evenly spaced). All rows share the same 0° reference (e.g. the badge), measured left to right from outside. Each set is a grid of Rows × Cols holes spaced by Pitch Y / X. Lug reference applies a real lug's hole spacing to your lug rows.
Wrap settings
Length = π × (diameter + vinyl thickness) + overlap. Holes inside the overlap are cut through both layers. Only use scale compensation if test cuts come out slightly off.
