[Elecraft] Self-fusing liquid electrical tape

[Peter Dougherty]

My whole ground system is Cadweld bonded. I bought the new style shots and purchased the igniter from Joel and the RF Connection in MD. Couldn't have been happier. And they're fun to fire off, too!

Cad-weld isn’t expensive — $11-15 per weld depending on where you buy the stuff.  Typically sold in kits of 6 one-shot crucibles, and available for varying ground wire sizes on 1/2” or 5/8” ground rods.
