saw this on ebay and wondered what thoughts you may have for use as a forge blower, Volume: 212 CFM (Cubic Feet per Minute) or 5.8 Cubic Meters per Minute

Holy molely what size forge are you talking about?
You only need a few 10s of CFM to run a basic forge.
Something like a spa pump that does about 1 m3/min (35 CFM) will be heaps and you will still have to slow it down.
Have a butchers at these.

I use a vacuum cleaner/blower running at about 1/3rd the full speed and I still have to end up spilling most of the air from that.
Way to much air, a clapped out old vacuum connected to a bit of old metal pipe can be quite effective. Providing of course it is on the blow not the suck end. http://d1r5wj36adg1sk.cloudfront.net...py/biggrin.gif
Thanks this is why I joined the site, so I need to find something about 40cfm,back to the drawing board

That is a jumping castle blower, plenty of them turn up at my local cash convertor.
They can be used providing you make a gate to regulate the flow. You could also use a variable speed if the type of motor allows for it.
I have an old commercial forge blower that is not too much smaller than that. The lever for the gate is actioned by an old mac truck gear stick.:U
It might sound rather odd but one of the nice things I like about small scale blacksmithing is that, apart from the necessary hammering which has its own timbre, it can be a rather peaceful and quiet process in comparison to a conventional metal shop using angle grinders and other noisy machinery.
What throws a spanner in this search for peace and quiet life in my small shed is the noise from blowers. I really don't like the screech of vacuum cleaners and the hiss of ventilation fans that sets me on edge and makes it harder for me to concentrate.
I don't know how others feel about this but this is why I recommend using blowers that are as quiet as possible. Using a big blower and then spilling most of the air just adds can add more noise than is necessary.
On small jobs I quite enjoy using an old hand crank blower, it gently whirrs while being cranked and is then quite. Also small car heater fans etc are meant to work well and fairly quiet.
It is a big blower and blowing a lot of air , I saw them on ebay as well for $110 .
I agree, a quite forge is better , Even though it's blowing heaps you could move it well out of the way and pipe the air closer with pvc Pipe , the electrics and the fan could be a safe 15 to 20 meters away in its own cover. the pipes distance and bends will use up some of that cfm and you could have the luxury of just the sound of the air coming from the forge.
What I use looks similar with 90mm outlet , it pumps a lot of air and a smaller amount ends up where I need it with the leaks and bends.
What else is there without to much hunting around as well ?
I never paid attention really but seen them lined up big and small. Prices of second hand stuff is just the luck of the draw.
I second the comments on noise, however my electric blower is rather quiet.
An air con fan from a car would work also rather well, all you need is a 12v transformer.
My little workshop is everything but quiet. Angle grinder, yes, wheel grinder, yes, cold saw, yes, compressor, yes, die grinder yes, air tools galore, yes, ha ha:U
That blower on a blower is an interesting solution. Why not motorize the hand blower?
Yeah :U It's a noisy hobby for sure. Id love a play on a power hammer one day , have to join a club to do it though , I doubt that I would ever own one . Angle grinding , a necessary pain in the butt , I love them and hate them at the same time.
A cold saw , that's classy ! I would love one.
Love my die grinders, they solve some problems nothing else could.
I like keeping the original blower on my forge the way it is, Just like to play with it now and then . mounting a motor to that would have been possible but tricky and It all just pulls apart and gets stored away . except the forge . Its not an easy thing to move around, a motor on it would make it harder. The forge stays out side with a sheet of tin over it.

On Gumtree at the moment bloke in SA selling them, No Papal though which make me a bit iffy.
If anyone if from Croydon Park South Australia any chance of sending me a PM wouldn't mind checking on the blowers if possible that anyone lived nearby to the guy advertising them he says he would give a demo
Power Hammer is more a question of location, that is ...how far away are you neighbours located ... hehe.
To motorise a hand cranked blower you must take out one gear and then attach the electric motor directly to the fan's shaft. For that you need to extend the shaft and fit a pulley to it
If buying made in India or China, check out alibaba.
The risk is the same then buying from that ad.
