Tire/Japanese Spring Power Hammer Build

Recommended Posts

Congratulations!!

 

What an epic project. It's inspiring to see how you stuck with this.

 

Only those that spend uncounted hours toiling to build something from scratch can know the deep satisfaction that you must have at this point.

 

Well done, sir.

NICE WORK DAN!!!!! Looks great too - I really like the contrast between all that industrial black iron and the straps and rope holding the tup assembly - very Japanese.

Looks like that "little" 2hp motor works pretty well. Awesome build! You can see the excitement that you've got in the video. Can't wait to see what you build with it.

Thanks Dave,

Yep- feels pretty good. And 3 months to build. That is like a record for me :D

Alan,

I wanted to be a little understated last night so I just let the machine speak for himself.

 

But this morning

WHOOP WHOOP YEA HA!!!!!!

 

The foot control needs some tweaking, needs a paint job and a name.

I am thinking one of the heroes from Celtic mythology.

Seems apropos for a Hybrid machine built in Texas by a Scots/Irish Kendo/Iaido guy to make swords in a traditional Japanese Kagi-ba :lol:

It was quite a feeling when that hammer head hit the first time. It was all about the voltage. At 120V it would start the eccentric and then you could hear a click from the motor and it stopped. Some kind of overload I suppose.

Rewired it to 240V and KABAM :lol:

 

Kinda scared me a little bit :o . But not for long. So then it was KABAM! KABAM! KABAM! I had no doubt I would make it work but I did not have the faith you did and thought I would need to get a bigger motor.

I chose the manilla rope largely for that reason and the fact that it has no stretch like the synthetics. The bright yellow 10,000lb tow strap is little out of character but that was chosen purely on functionality.Plus I can always Wabi-Sabi it up with some charcoal dust. :ph34r:

Dan,

Congratulations! You probably have just hit on something by not having a 1 piece hammer..this thing really seems to act like one of the Japanese style hammers I have seen ( on you tube). I really like the idea of a tup moving only in the vertical direction...my 50 LG has a little rocker motion at the bottom of the stroke ( which I have learned to live with but do not like). I will send you a P.M. tonight, regarding some steel samples.

Thanks Mark,

Making a run to South Texas next month. Shooting for October for my first Kodai Tatara. Just had an email from a customer in East Texas. I had told him of my side line interest.

 

He said he has a bunch of ore he gathered off his place for me. Anxious to see what he has. The area was a big steel producing center for the south during the civil war.

 

The South Texas mag holds the most promise I think. The Japanese iron sand is mountain sand that has weathered from biotite granite. The Texas Magnetite is found in conjunction with biotite granite. Trying to find a local geology department that will give me a definitive analysis.

Me too! If you're game so am I. If there is a better departure airport for you let me know. I have a spare bed and we should be cooling down by then.

Nice. You must feel like a proud papa. Looks like everything it coming together for the kajiba.

That was Beautiful to see.

 

Such a great feeling it must be. I am looking forward to see how it moves hot steel.

 

The shape of the hammer face and the anvil will be important for how it moves and draws the material.

Have you made a slight crowning of the hammer face, or is it flat with beveled edges?

(Perhaps you have commented on this already, sorry)

 

Your workshop is charged with goodness: seems like a very happy place to be.

 

Great work!
