INDUCTION LAUNCHER
I have all the parts connected and ready, just need to add new SCR/switch et al.
The SCR at PIN 1 exploded on the first 2 tries. Tested w multimeter and determined SCR was busted.
I copied the components from this youtube vid:https://www.youtube.com/watch?v=8qEH8NAI2TQ&list=LL4sbmwrdGZSvPH4DlIHtY0Q&index=18&t=0s
I need a new SCR and perhaps a different configuration - would love some positive constructive suggestions and feedback.

what's the current rating for the scr?  as soon as the coil's field is generated, you're going to be flowing current through it as if it were a resistor only, is the scr going to handle that?
