I am progressing nicely with my quarter shrinker. I recently finished the blast cage made of 3/8 inch steel and G10.
I now have a question concerning the pulse capacitor. I have one of those Aerovox 2-terminal units. Should I ground the case or just leave it floating? I am currently planning on connecting a dedicated earth ground to one terminal of the capacitor.
I also have a question about charge/discharge meters. I am currently planning on using separate meters for charging and discharging. The reason is that I had some concern about having a single meter connected during the firing event even though one side of the meter would be grounded to earth. The charge meter is a 0-25 microammeter with a 1G ohm multiplier resistor. The discharge meter is 25-0-25 microammeter with a 1G ohm multiplier resistor. What are you using?
