Casting Table
The Casting Table makes iron round shot in different calibres. Use small balls for handheld firearms and 120 mm balls for the Culverin and Serpentine.

Craft one table with an Iron Block in the top centre, three Planks across the middle row and Logs in the two bottom corners. Any wood accepted by the corresponding vanilla tags works.

Open the table and select a calibre with the − and + buttons. Calibres run from 5 to 490 mm, in 5 mm steps. The screen shows the required iron and the number of balls produced before you cast.
The table takes Iron Ingots directly from your inventory and puts the finished batch there. You need enough iron and room for the entire batch; an unsuccessful cast consumes nothing. No fuel or fluid is required.
The bundled recipe uses one Iron Ingot per 120 mm ball and scales the cost by volume. Small calibres produce several balls from one ingot, capped at 16 per batch.
| Calibre | Iron Ingots | Balls per batch |
|---|---|---|
| 15 mm | 1 | 16 |
| 20 mm | 1 | 16 |
| 60 mm | 1 | 8 |
| 120 mm | 1 | 1 |
| 490 mm | 69 | 1 |
Available calibres do not mean every gun accepts them. Check the weapon's calibre before casting. Mons Meg uses its giant stone ball, not a 490 mm iron ball.
| Calibre | Maximum stack |
|---|---|
| 5–100 mm | 16 |
| 105–160 mm | 8 |
| 165–300 mm | 4 |
| 305–490 mm | 2 |
The calibre also determines the size of a placed iron ball. See Ammunition Guide for stone shot and other payloads, and Data Pack Reference for custom casting costs.
