Ends of what? Wire? If you choose to use leaded solder for some reason, then you break out the electrical tape afterwards and wrap that connection solidly.

Tungsten is pretty dense stuff. Even Tungsten Carbide isn't bad. If you can find scrap electrodes from TIG welders or get scrap carbide mills and inserts from a machine shop they would work OK if you can pack them closely. Most recent price I saw for Tungsten shot was $24./lb. Scrap carbide tooling is maybe $8./lb.

If you are going to use tungsten electrodes,
make sure that you don't use the thoriated
ones. They are radioactive.

We like to use gold paint on lead to make it safe.
