Hi,
I have recently bought a new spindle which has an HSK32 tool interface. I would like to move to shrink fit tooling, but cannot afford a machine to do so.

Electronics is my thing, so I could entirely probably make my own induction heater. It sort of comes down to power, easy to make something up to 1kW lets say,
but a damn sight harder to build something of 20kW.

Does anyone know, or have experience, about the power levels required to make shrink fit tooling practical?
