best value induction heater diy style

[petehall347]

wondering if anyone can guide me through the minefield of diy kit induction heaters ? its for mainly hotting up seized nuts on cars etc .
i see by design these things can fail pretty quickly if badly designed .
maybe some of you have and use one that can be recommended to me ?

just wrap some turns of the thickest copper wire you can find and then get a stepdown transformer to output a volt or 2 at some huge amperage.

After years of wrangling with rusty bolts on cars I bought a DeWalt DCF889. I've yet to meet something it can't undo.

i work on plenty of stuff thats so seized from rust even one of those wont undo the nuts/bolts without heat .
i have a decent blowlamp but it tends to set fire or melt plastic and rubber parts close by .
this is why i thought a decent induction heater that only heats what you want to get hot .

Fair enough, I should count myself lucky I don't have to work on such rusty stuff.
