Hello guys...

Rose and I made it to Amarillo OK, Were staying at the Day's Inn
until we can find something to call home (with a BIG workshop of
course!)...

Don't see much activity on the group these days.

Anybody out there reading this?

Hi Ken

God?I hate moving

When Joanne and I moved here she was in the hospital having babies way to soon. Thank God for lots of friends and family including my father in law who broke his foot for his effort.

?

Greetings all:

?

I found a 21" diameter water tank that I cut in half and added flanges to both pieces cut in 12 electrical feeds about 14 up from the flange for the evaporators and 2 near the top for the glow discharge the glow discharge is connected to a 6 KV 35ma neon transformer. This isnt as bright as I expected so I am going to try -1ST grounding one side to the case 2ND using a larger 10kv 65MA transformer that I just picked up.

I have a small 300W air cooled 2 diffusion pump that is part of a leak testing setup I picked up on e-Bay. The diffusion pump setup flow starting from the vacuum / (Searss water) tank has a pneumatic valve, pressure gauge ports a Valve, cold stack, a valve, and then the diffusion pump.

?

I have been able to get the vacuum low enough to stop the glow discharge (about 20 minuets) but not low enough to evaporate the Al this may be due to the small size diffusion pump or the amount of piping before it. I did find a small leak at the pneumatic valve last time I tried it.

?

Im still trying to find vacuum gauges that work I have 3 controllers and 2 thermocouples and an ion tube all purchased separately on e-Bay and I havent gotten them to work yet.

?

I have a 6 water cooled Diffusion pump I am going to try today.

?

Now the questions:

?

How bright should the glow discharge be? It isnt giving enough light to see anything in the tank.

My Tungsten wire is way to big .045 so I need a lot of power to get it hot how hot should it get Dull red, Bright red, almost white? Will smaller wire hold up better or worse?

?

Working sucks (no pun) I hardly get any time to work on my projects.
