New Spark Gap

After weeks and weeks of more work, the spark gap mark III is at long last complete. Are previous 2 died on us so here is the final installment. It is much more robust and can handle the max speed without warping. The disk was cut on a CNC laser cutter and the motor is secured to the base in a much stronger fashion now. We also opted to mount it downwards instead of the usual vertical orientation to help support it. Overall the whole assembly is designed way better than the earlier designs and so we are sure this one will be the final version. Here are some pictures:

I go away for a week next week so work will be postponed. After that however its full steam ahead to finish the coil. See you in a few weeks.
