Gas and Induction forge
General Information
The gas and induction forges are located inside the Metal Shop. When using any equipment in the metal shop, wear all proper safety equipment.
If you have any issues with Metal Shop equipment, the slack channels for this space include #general and #shop-metal.
Orientation
This orientation assumes you have already completed the general space orientation.
- Do not operate any power equipment if you are under the influence of anything, in a hurry, tired, or not feeling well.
- Inspect the equipment before each use.
- Wear appropriate PPE: heat‑resistant gloves, safety glasses, closed‑toe leather shoes, and natural fiber clothing (cotton or wool). Avoid synthetic fabrics.
Equipment
Gas Forge – Housemade Apollo Forge
The Apollo Forge is a propane‑fired gas forge suitable for blacksmithing, knife making, and heat treating.
- Outer dimensions: 11.5"W × 12.25"H × 19"D
- Inner dimensions: 4.5"W × 6.5"H × 18"D (forge volume approx. 530 in³)
- Maximum temperature: Up to 2,400 °F (1,315 °C) depending on propane pressure and burner tuning
For detailed startup, tuning, and shutdown procedures, see Gas Forge Operation.
Induction Forge – Coal Iron Works 15 kW Induction Forge
The induction forge uses electromagnetic fields to heat metal rapidly and efficiently. It is ideal for localized heating and is safer than a gas forge for many operations because there is no open flame.
- Power: 15 kW, requires a dedicated 240 V, 60 A circuit
- Heating: Small pieces reach forging temperature in seconds; depth of heating adjustable by coil design and power level
Setup notes:
- The forge must be connected to a water‑cooling system (chiller or tap water) before operation – never run it dry.
- Work pieces must fit within the induction coil opening.
- Do not touch the coil or the workpiece during heating; use insulated tongs.
Recommendation: Most single users should stick with the induction heater. It has much faster setup, tuning, and cooldown.
