Oh ya i almost forgot.
Important! When tuning your Tesla coil's spark gap ALWAYS WEAR TINTED GOGGLES OR WELDERS GLASSES. You only have one pair of eyes.
Another good point is to have good protection around your primary winding around the bottom to prevent inadvertent contact with it while making adjustments. This is something i will be implementing in the future. Having a set of test leads around to short out the cap bank at your spark gap is always good practice even if they tend to finish up discharged normally. There is no accounting for mistakes or rare occurances with high voltage. We all want to be around to enjoy our efforts.
Anyway just a couple of pointers from a newbie who has already had a couple good shocks. :P
