In Response To: Re: Masonlite Electrodes (SVP Neon Equipment)

I'll keep coments short. I have 2 electrodes that i welded together and pumped. We put a spindel in a drill, rotated it smacking the electrode against hard rubber strips to get the collar to bang against the glass. 40,000 hits on each trode and the ceramic was breaking apart but nothing to the glass.

We still make the 8C and 9C trodes without the collar and put the mica sleeve in side. It was stopped because the collar keeps the shell off the glass

If they are to tight the collar can crack during bombarding
The JA's

This is because the lead wires have to hold the shell in place. With the larger trodes, they can bend the wires from weight during shipping and bombarding. Ours still have the mica sleeve in the 19CM and 19CL. Mason could've had to use a disc because the lead wires were not strong enough to hold the weight. in Europe they pump differntly than here. We try and get the tube bombarded in about 120 seconds where they use a longer pumping method. We bring the trodes up to temperature fast and furious.
