Thanks Bob and John.
It was nice to read your detailed explanations of the 15G's construction. I counted five glass-metal or metal-metal junctions. That's ten bound surfaces. This is a mechanical engineer's nightmare. Have you considered using a large molten glass band to completely encompasses the Ultor ring? This glass band would be fused to front and rear glass surfaces of the 15G. It would include a feed-through connection to the Ultor. If this technique is mechanically sound, wouldn't it eliminate most if not all of the sources for vacuum leaks? Kind regards, Terry Cheek
