A handy aloe would have been nice the other day. I was heat shrinking a bunch of connections and set the heat gun on the floor since my work space was so cluttered. Then, being barefoot, I promptly brushed my foot against the hut metal ring around the business end of the heat gun. Yikes that hurt! I know - don't put ---steaming pile of meadow muffin--- on the floor ya dumb ass! |

How about "Don't work barefoot"? Eh, we all forget safety bits here and there. I had a near miss a couple weeks ago when I was cutting a bolt with my dremel and had an itch on my head. You think I would be smart enough to turn the dremel off and put it down first. I could feel the cutting disc millimeters from my scalp. |

Heat guns seem rather poorly designed if you ask me. A hair dryer heats up so the metal duct of a hair dryer is surrounded by a larger plastic shell to keep you from burning yourself. Heat guns.... nah we'll just make the entire tip out of metal.... what could possibly go wrong? |
| MonMotha:
Heat guns get much hotter than hair driers. They have the same amount of heat output but lower airflow. The plastic shell surrounding metal air duct of your typical hair dryer would start to melt at the temperatures encountered in a heat gun. I'm sure somebody can point out some high temperature plastic or thermal insulation strategy that would be reasonably effective in this situation, but it's far easier and more reliable to just go with metal. You might also want to look at some of the more modern heat guns. Many of them feature adjustable temperature as well as automatic cool-down modes which will at least serve to limit the amount of time the metal duct is at dangerous temperatures. |

(like most hand tools these days) of course, it would increase the cost of the tool. |
