Hi
My name is Alan .

Im going on 52 years old, and my arm is shot.
So I had been looking for some type of power hammer for years, but good LORD they are a lot of money.

Then out of the blue a guy I know was talking to me about my not making any knives for a year and when he heard I needed some type of power hammer he said he could make me one.

Well I had my doubts, but after a few months I saw him again and he had it finished.
It seems to work fine, but in his design it is driven by compressed air that he has connected to an old air powered hand drill.

The problem with that system is that as you step on the switch to start the thing working you bleed off the air from the compressor air tank and the power always is dropping .

My goal now is to learn how these same types of power hammers are connected to an electric motor with some type of switch or floor clutch?


I will be recording a video today and have it posted, 9with luck) within 24 hours.
Once I get the new video posted that explanes what Im looking to learn from you guys, I will be ready to get busy with the conversion of this thing to electric motor drive.

Nice set-up.  You shoud do a search on Clay Spencer's tire hammer.  I've got one and it's great.  Runs all day long on a 1 horse motor.  It uses a spare tire for the clutch and it has as much or more control than a little giant hammer.  I'm afraid your hammer lacks the anvil mass and hammer weight to ever be truely efficent.  Looks more like a planishing hammer than a forgeing hammer.  You might also think about a forging press.  Personaly I like having both.  A knifemaker I met a while back has a rolling mill and I'd love to have one but don't think I'll get on anytime soon.

I've been meaning to give charcoal a try, not the brickets, but pine as I've got free access to wood scraps, just haven't had the time yet.

Sorry, ment to add for the foot control, it's basicly an on/off valve, you should be able to find a rebuild kit from Norther tools or other suppliers.  You could also see if you can look up the manufactures website and they should offer rebuild kits.

If it's all you got, by all means use it.  My first power hammer was a "rusty" that I built, a spring helve hammer.  it wasn't much of a hammer, the anvil was too light and the clutch never would feather, it's basicly run wide open or stop and it liked to shed bolts and nuts at times, but it sure beat swinging a sledge.  Looking back it was a piece of junk, and a constant frustration.  But it did it's job till I could get something better.

Good luck.

Perhaps my video is not clear?

I seek to convert my air powered hammer to an electric motor.....
I am asking for how to do this, and how to connect the different belts and wheels?

ive seen one with electric motor,flywheel,clutch home made by a mold maker at a foundry....LOTS of precision engineering if you want to do this and you are not a machinist with a degree in engineering find one close to you....if you want i can see if he would let me take pics of his and ill post them so you can get a look at it

It seems to me that it should be very easy to do, once I see some designs of others efforts.
That is ready what Im asking to see.....some photos or video where a guy powered his hammer with an electric motor.

One of the ideas I have is that I make the main shaft that is now connected to the air drill to be longer.
Then at the end of this new longer shaft I would mount, (somehow) a wheel or a small tire.
Then I can just have an electric motor mounted below this wheel.

The motor would be able to move slightly up and down while it is spinning.
Then (somehow) I would have a foot bar that would just push up on the electric motor and cause it's spinning shaft to rub into the tire and begin to spin that.

It sounds easy.....

Let me post a video to give you an idea of what I have been thinking about, and see if you know how to pull it off?

Sorry about that, was thinking you were wanting to fix the air drill system. &nbsp;The easist way to do it would be put a motor and pully on the shaft and a slack belt tot he motor. &nbsp;The slip pully on the shaft needs to be turned out to where it's basicly a flat pully with square sides to keep it on the pully. &nbsp;A standard V pully will grab and go, the flat pully will slip. &nbsp;You'd need an arm with an ideler pully on it to tighten the belt and make it run, more tension or less for speed controll.

Anvil fire is a good place with home built hammers. &nbsp;http://www.anvilfire.com/power/morepowr.htm

Here's the basic "rusty" ANA "dusty" &nbsp;it's got the slip belt like I was talking about. &nbsp;http://www.appaltree.net/rusty/super_rusty.htm

I found a design I think might work!

I saw this YouTuber video and I think it has a design that I might be able to copy...

well....I found a electric motor today, and also got one belt pulley.

The guy at the store that sold me the pulley had his doubts about my design.
It seems that the motor will spin too fast on this design, but I have the hope that things will work out.

I have send out a lot of requests for someone to shoot some video of their power hammer so I can actually understand how to bolt this darn thing up....but so far no takers.

I just need someone to show me how they ran their foot bar so I have an idea how it works?

Tonight I disassembled the old air drive and got to work making a new longer main shaft that will connect the vertical bar to the spinning pulley.
It went well, and with luck I can start of connecting the large pulley to the spinning shaft tomorrow.

After that I have to stop and think about how Im going to make a foot bar, and what the foot bar will be bolted to, and how that will tighten the drive belt?
