Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Here are the promised images of my attempt to make a hot air pencil from Weller iron parts. These items spent about six months working (kind of) and were shelved for good. The year was 1994 or 1995. [Image] Complete view of the device. The handle of the iron has melted, it used to be straight before. The white box is the aquarium pump (with two outlets). The green parts are aquarium air hose 'T' joints. The two film cans hide a certain kind of balloon. It was supposed to smooth the airflow (which comes in pulses from the pump). [Image][Image] Two views of the front end of the tool. As I have said, the original heater only lasted for a few minutes. It was replaced by a spiral made of 2A wire (1/10 of the length of 220V 500W heater wire), fed with 24V ac. The small screw retains the front end of the spiral. The spiral is fed between the body of the element and an internal wire that runs insulated up to the beginning of the airhose in the handle, where it pierces the hose, and is connected to the other power wire. This device had serious problems: - It made too much heat (about 50W) - The pulsed airflow tended to move small parts after melting the solder - The heat was so intense that the handle melted and the airhose was replaced once a week or so (by cutting the melted part and splicing it in the handle). Wear this in good health and let's hope that you will not make the same mistakes I made. Peter
