Idea is to make a 3kW induction spool to smelt metals and heat steel for forging. For examples see :
Smeding had designed a circuit and made a BOM, see below:

Additional hardware
In addition to the inverter circuit, at least the following things are needed to make a working induction heater
| Component | cost | Possible sources | requirements |
|---|---|---|---|
| Coil | € 15 ? | Gas tubing, car brake tubing | Copper. Sufficient copper area to handle the current. Sufficient inner area + diameter to allow for effective cooling |
| heat exchanger | €15 ? | Car junkyard | Unsure how much heat needs to be removed and at what temperatures. Worst Case would be 3 kW. A car radiator is probably good (cheap, sufficient power and an integrated fan) |
| Pump | € | Possibly a pump from a domestic heater (CV). | Have to check whether or not normal sizes create sufficient flow through small diameter coil tubing |
| Electrical connections and wiring | € | Battery connections form scrapped cars? | How much current do we expect, and how long do the wires have to be? how do we connect these to the coil tubing (Earth blocks? |
| ... | |||
| Total cost | € 30 (incomplete) |
Now we need financing. Initial estimate is that we need at least another 50% on top of the BOM to get the box, spiral, coolers etc. Goal is thus 150 -200 euro
