<div dir="ltr">The heater cones were (are?) a ceramic cone with a medium-screw base wound with nichrome heater wire that was screwed into a base within a metal reflector and used as a very early space heater. Usually had a medium-gauge welded decorative wire cage over the face of them. Scary from an operational standpoint let alone the fumes given off by the sal ammoniac. Another example of a device used for something other than its original purpose. <div>Steve</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div>Stephen E.

However, I have never seen this done, nor even seen what such a heating cone looks like. A search for a "heating cone" shows up some cone-shaped systems which you use to heat a bearing (I am guessing to expand it a bit, to put onto a shaft). Is that the sort of "heating cone" used for smoke?</div><div><br></div><div>A search on Youtube also turned up nothing except how to clean your soldering iron.
