Hi Jim -
I like your approach, but I'm a little confused.

You say: "take the Elmer's and fill it to the brim of the grid cap". Should I do this without digging the old stuff out of the grid cap, or dig the old stuff out of the grid cap first? Seems like the grid cap wouldn't hold much Elmer's if you didn't dig the old stuff out first.

You say: "wait for the Elmer's to set and flip it over...". By "set" do you mean completely dry and rock hard, just skinned over, or somewhere in between?

You say: "look until the grid wire was poking through the hole". Look at what? Through what hole? Do you mean make sure the grid wire is inserted into its original hole in the stuff packed in the grid cap?

You say: "...add a little solder to the cap...and wait" Where should I add the solder? At the grid cap/tube glass junction? What is the purpose of this? Is it to solder the remaining grid wire to the grid cap? If so, shouldn't you flip the tube upside down so the tube is above (and somehow resting on) the grid cap and so the solder can wick around the remaining grid wire with the help of gravity? And finally wait for what? The assembly to cool?
