To: @DavidR, @cltattooing, @jen7, @bongsau, and @Abellve. Thank you for all ya'lls reply.
I am around. This thread got to me a bit and I just need to sit back drink a beer and relax for bit.
Thank you gals/guys. @jen7, Engineering background (By trade) here as well. Metals/Engines/Electronics just fascinate me! The knowing of how it all works.
