I have them in my fabrication workshop since father's time. and they are pretty good for my fabrication work that is straightening, bending,  sheet metal fabrication works, etc. I have seen many of them around me. if you would like i can send photos of my press

well as far as my experience and knowledge goes these are not the type of presses which goes mechanized by power.

between you have shot for applying working principle of forging screw presses but i dont think that will go work on such small level effectively.

still the flywheel which you are using is creating the inertia for your working i will definitely never suggest someone to do this,

1. too much hectic

2. you will need geared motor (costly stuff and finding one in junk yard is next to impossible)

3. you will need custom built bevel gear (another costly stuff)

4. there are maybe chances of loosing power rating

so all and all i would never try to modify instead try another hydraulic press

hope this will help you

How many believe that there should not have been a winner last week

perfectly said 

as far as my opinion concerned a bend and broken both are failure

and as this week was concerned Illya was a certain winner for shield making. I watched his videos over man at arms as compared to them his knife came out under expected.

so the the waiting ends right here

I managed to complete it with fabricating a stand for it more descriptive images are here

would an H13 rod be a good metal for making a touchmark?

Yes H13 is quite good

I think you should figure out why the Chinese blowers burned up.  It could be your setup.  If you shut off the air to your forge are you dead heading the air?  If so, that could burn up your blower.  I know a lot of blowers can't handle the pressure that causes and they fail.

i found out that those chienese blowers were not meant to be made working for long time, in long term run the whole roatar and field windings got heated up and due to collasion winding got short

so far so busy these days but i managed to have some progress

i managed to put fabricate housing with a elbo as i do have a bottom blast except elbo all other parts are coming from my scrap

there is a flow control which is just been in design and i have used it first time will provide more detail about it when it will work

but for info when you move this hex head this will change amount of air out

And for all the balancing Fans

Yess!! my fan is already is pretty much balanced and didnt gave any kind of balancing problem in my test run!!

And thus it is proved that you can make your own fan in welding workshop

Rather than make the assumption, I'll ask............Anditya, are you intending running the fan directly from the motor at the full rpm rating, or will you be including some form of reduction gearing between motor and fan?

right now i am thinking about full speed and direct mounting but if problem comes i do have option of step down pully

I'd seriously reconsider this. I would *not* trust the quality of those welds at 1440rpm. Your weld prep is non-existent, and flux core wire is ill advised for this under the best of situations. Your backing isn't going to be stable enough to resist the centrifugal force of the blades which will drive them into your housing at speed and *really* test your welds. Not to mention those blades will effectively be little more than tissue paper trying to move air at 1440rpm.

Why not just use a motor/squirrel cage from a preexisting fan setup? Or even find a squirrel cage from an automotive application and fit it to your motor? 

1. these welds what you saw here are just tac weld i am going to full weld those from both sides

2. as far is welding on speed rotation considered i have seen many of my welded job turning on high speed and taking deep cuts and welds always worked fine

3. when the backing comes in play the back or housing which you are viewing right now is going to weld on one metal structure which will going to hold motor and housing both

4. i am still searching for appropriate squirrel cage/ fan blade in market but i am not getting one.

or do it handcrank at least at first to see how it works.   1440 rpm, if it works, gonna blow your coal outa the firepot.....   Possibly blades with it.   Hand crank lets you put air when you need it too and at the right amount.

u gonna be able to get that thing in there????

i havent thought about handcrank i need to reduce human efforts

but i am going to put valve or damper in between blower and forge to control the flow

If you have any balancing issues on the blades (IE: alot of vibration) I read somewhere that people were using rivets to balance them. 

thanks for idea duckwalk will try it when i will take first run

I had some more progress done before leaving for home

fan blades are tapered and positive rake angled to push air towards wall

See the lirics to "third rock from the sun"....

at that speed it has to be a well built and balanced fan. Are you fabricating or using a pre-made one?

My search for premade in market is going but many of associates gave Me Negative replies 

But i do have my backup plan of fabricated fan with tapered and positive rake angled blades

Is an internal keyway the same thing as a woodruff key?  A little metal piece that stops a wheel spinning separately around it axis.

Yes internal key way is in holes to hold those keys 

After blowing up 2 chinese air blowers on first runs I have decided to make my own air blower (hoping good use of my old 0.5hp motor )

Specification

Power - 0.5 hp / 1440rpm

Dia of Housing - 10 inch

Dia of fan - 8 inch

Width of fan - 25 mm

Out Vent Dia - 1 inch

Right now Mounting Shaft is gone to friends shop for internal key way

hope it will do my work will keep all informed when it will perform

another very nice sculpture Das

keep coming with more  

I had built and sold mechanical power press even had repaired piles of them .

I had always made presses by what i can actually find in workshop or i could get from scrapyard

But let me tell you for this you need quite bigger machines and many special attachments only if you can manage those or contract it outside will be good

Depending on which machines you do have in your workshop

Many of parts needed to be cast or fabricated if you do have any casting supplier then only try to build it

Don't worry about metal you have got this will make a very good hammer, this steel is made for cyclic loads and wouldn't gonna fail. 

For a 4 lb pound hammer all i am worry about is that you will end up with too long hammer, so try to forge it concave shape on hardy hole upside down after final drift placed inside eye, i think it will help to reduce length 

Awesome reconditioning 

Sure  it was made for non ferrous casting furnace 

Haha i dont think so 

 Atleast i would never build such one

Okay many of guys won't gonna believe such thing can follow home 

It's a motorized blower of 30 inch diameter fitted with a 3 HP motor 

Seller is one of my father's friend he told me it was not used since 4-5 years but it was in working condition when he demolished his smaller furnace and gave me pipe which can join it with burners so it can be run on some kind of thick furnace oil

Even i dont like to forge on ground 

Thank you sir

Thank you 

We do have many things to share with you guys and some things to learn from you

Thank you

Hello guys I am from MH, India. I own a hardware store worked for 12 years in metal field. I had worked in many fields like fabrication, machining, press work, tool room, etc. But i never worked in blacksmithing .

This motivated me for building a forge (which i am working on) and i found this forum. 

I have a small workshop where i can work some of my Machines pics can be seen in my gallery.
