All but deleted account Posted March 13, 2017 Share Posted March 13, 2017 A friend recently gave me two centrifugal fans and I want to make an electric blowers with them but I don't know where to start. I've looked around here but I can't find anything on the topic. All I have are the motors with the two wires (pos. & neg.) sticking out. I was thinking about maybe using a variable light switch to increase/decrease the speech at which the fan rotates but I don't know how to do that nor do I know how to actually power it: what to connect how to connect, etc. I'm trying to melt some copper and silver to cast a couple of rings but with the old "blower" I had, it didn't work (it was a hair dryer duct taped to the end of a pipe that was stuck into the ground into the forge). Can anyone give me any advice? I would also like to have a pipe attached to the blower with a container or something on top of the end of the pipe to hold the coals and the metals.

JHCC Posted March 13, 2017 Share Posted March 13, 2017 Hi, Amolith. There are a number of good posts about making blowers with fans, so I'd recommend doing some more research and seeing what answers have already been given. Pro tip: ignore the forum's native search function, which is no good. Instead, do a google search using "iforgeiron.com" as one of your search terms. I just did such a search with "squirrel cage blower" as the other term and got a dozen hits right away. Quote Link to comment Share on other sites More sharing options...
