I Forge Iron


Failed Attempt

Recommended Posts

After looking into different options for my forge blower (hairdryer, electric duct fans, vacuum cleaners, car heater blowers) I decided to try building my own. After a lot of research on this site and others I concluded that I want a handcranked blower.


I didn't have a build plan other than that the only case suitable for a blower was 200l barrel. Other than that I had to use whatever scrap I had lying around. The case is a 230mm cut from the top end of the barrel. The lid sealing the case is a piece of 1,5mm sheet I already had. The axle for the fan is a length of 30mm hydraulic tube and the fan blades are cuts from the barrel sides. The back plate supporting the fan blades is a piece of 4mm plate I also had lying around. The stand and the frame is mostly pieces of steel frame from scrapped sofa and various other bits of scrap. I couldn't find gears large or small enough to get the gearing I needed with just 1 set of gears so I butchered and old excercise cycle for the secondary gear set and the primary is from an broken bicycle. I didn't have any suitable bearings for the fan axle so those I had to buy. Sorry about the lack of pictures from the fabrication. At the time I didn't think this would ever amount to anything but a failure so I found no need to document it.


It took me about 12 hours spanned over two weekends to make this. I didn't aim for anything more than a proof of concept so I can see if it's even a functional design.


Tools used. 125mm angle grinder, power drill and 150A mig.


Now I just need to hook this contraption into my forge and HOPE it pumps enough air.


This is by far the ugliest thing I've ever built.
