5-Series 3/4" Diameter
Tungsten Spark Gap
Drilling out heatsinks for 3/8-24 Tap
The heat sinks...6061 aluminum. Fins are parted with a parting
Other end has a 1/4-20 tapped hole
Here is how I tapped them...
Brian Foley sent me some awesome 3/8-24 silver plated copper set screws
Heating the tungsten disk...
Extremely hot still, brazed with very hard silver solder
Two sections of the gap...needs polishing, but testing it first...
Really crude, but I can't wait to test it!
This looks good...
So does this!
