I went a little crazy on August 8. I purchased at least 500' of most even gauges of kanthal SS nicrome. I have played with a lot of coils. I find a fused spaced Clapton or tiger wire works. Like Walt I have micro coils to 3.5 monster. I love the challenge of building staggered fused Clapton's. I follow some of the great builders like Aries jj ohm Boy Josh. Squido and yetisuncle. It don't get old. And love steam-engine.org
