Bench top power hammer for blacksmithing

Hey guys and gals this is a video I made of a small power hammer I built to save my shoulder a bit.https://www.youtube.com/watch?v=BJotNQgjQXs&t=1s

gee... thanks... a lot...
[frowny face goes here]

Now I have YET ANOTHER PROJECT to do!
:-)

This'll have to come in behind my 24" disk sander with full variable speed (via VFD) and tiltable DISK so it can lay flat for 'lapping'

I'm making it with MDF faceplates that can be quick-changed for different grits, and even polishing and lapping.
:-)

But, this little hammer is a beauty!

I'm a touch concerned about the longevity of the spring, and about the exciting time when it breaks.

Maybe putting a tension spring on each side of it would keep the frame centered some yet allow for drift side to side as it goes whammo!

Hmmm...

I also LOVE that it cost you around $100 to build. Those are the most fun projects.

Glad you like it man.It really does work well.The Ca$h spent on it was for the pillow blocks/bolts and I had bought two small motor pulleys.The step down pulley was from an old benchtop drill press that broke,glad I kept it,the step pulley off it worked out great.Thankyou,Mike.

WOW! im blown away,Thankyou so much.I consider this a great honor and very much appreciated!

Great build, congradulations on your win

Awesome build man.....I wish I had 8" bar stock in my junk pile. Congrats!!!!

Well deserved award, I like the design and the use of repurposed materials.

What a fantastic setup! Thank you for sharing!

Very impressed! I am surprised that a compact powerhammer like yours doesn’t bounce about. I did not catch the channel’s name you mentioned which you found so helpful. Also, how do you prevent wear on the main spring?

Well done.
I've been kicking around the idea of building one but to be honest i've been a bit intimidate buy the whole thing. Now I think I will give it a try in the near future.
Thanks for sharing your monstrosity with us.

Very nice build, extremely ingenious use of metal just laying around in stock inventory. It isn't scrap until there is no further use for it and even then would still be useful for ballast. After we moved to Buffalo N.Y from northern Illinois, I still haven't recovered. Still have a lot of stuff still in storage back in Illinois and wife just had hip revision so I am not outside as much as I would like. Gotta build a treadle hammer, power hammer, get lathe running. The 5hp rotary phase converter I built just isn't big enough to start in high speed so undecided on building a 7.5 or buy a vfd. Just so many projects. Closing. I will say again, very nice build.

Nice build Mike. A question. What happens to the drive belts with the brake on?

Very cool power hammer. I really like the setup you used for the brake. Very clever.

Does it ever work? I quickly scan through the video maybe I missed it.

Yea it works. Watch the complete video :)

Great work!!
