A better x-ray:
That is a better X-Ray, Have you tried to straighten the filament in this one yet?
Rich @ 2960.33 degree Fahrenheit there is not a lot of metals that wont move
We tried today. The X-ray was no help. We found the direction of the bend by increasing the current in the filament-grid arc. After centrifuging the filament-grid BDV increased about 30%. Next time I raise the filament V. and find someone who can spin it faster.
Rich, are any of these the tubes I sent you? Lou
No Lou. We have been experimenting with the 3 we had on hand. Things have been going pretty slow lately since helper girl #3 has started cosmetology school and helper girl #4 - a.k.a. Wonderwoman - is expecting.
Might be tine to build a centrifuge, there are plenty of washing machines out there that could be converted for this application.
Yes. It improved the filament/grid BDV about a third so it seems we are moving it in the right direction.
