For some time I have been looking to make a small induction heating coil for general interest and heat treatment of small items. Despite searching online I have failed to find enough information to make such a device. There are plenty of sites showing them working (eg Utube) but very little in the way of practical help in building one.
               Has anybody worked out how to build one or where plans exist. I am sure I am not the only one daft enough to want to build one.

Hi Douglas,
                       Here is a link to a web page with links to some induction heater designs.
I did a Google search for "induction furnace diy" to find it. I have come across other websites in the past with other designs but I can not remember where. You sometimes see induction hotplates for sale that could be a basis for a small induction heater.
Good look with your experiments.

Thanks for these responses to my query about induction heaters. These two sites were new to me and look interesting. The open source plans on the site mentioned by Andy look very promising and I will study them in detail when I find the time. Sourcing the bits might be the biggest problem despite my having quite a large electronic junk box.

I'm interested too, but not keen in electronics, is it possible to use a high frequency generator borrowed from an inverter arc welder?
