Good advices for a newbie (threading tools lathe)

Looking Good Stefano. Layout is one of those things on a project like this that must take a lot into consideration like close coupling, isolation, grounding, spurious emissions, let alone all the mechanical's...etc. In this case the biggy is HV AC/RF to DC to Audio...and Ground planes. The other is porting thru a Faraday cage. What you are doing placing the actual component on the chassis is the best way to flush out the puzzle of this type. Take your time and go to that Zen place with it...eventually its cork will float.

Did you measure these temps? Silver solder would work up to about 500Cº. My suggestion for the Tungsten electrode would be to make a mechanical connection. Maybe a double ended, machined brass ferrule with minimal (slip fit) for the tip and conductors and maybe 12-15mm diameter so you can put in 2 set screws (3-4mm?) for each end. One set screw (socket head dog point or cup, type not cone) would work probably, but 2 better @ 60º. The key would be to keep it small diameter as possible to keep the spurious emissions down in that area. As for a support maybe a rectangular block of PTFE if you have it...it's should be good up to about ~200Cº. Maybe 2 square porcelain standoffs with a smaller block between them for support¿ It would also depend if you will use the ozone isolation glass tube. Alignment to the cone and some kind of fine tune adjustment would help to dial it in.

As for the coil, your porcelain tube can use a mechanical half cup type connection through the existing holes at each end and supported by some of that green stuff or UHMW blocks or a ring?? Good to ~200Cº...it should never get that hot...hopefully. Make sure to clean all the burns from it.

Like the Steam Punk idea but don't let it dictate what it needs to be electronically.

Thanks for the update! ~PJ
