Powered Hammer

[Onoff]

My niece (30) has severe rheumatoid arthritis. She is a keen jewellery maker as an aside to her day job.

My brother messaged me "Thinking of getting one of these for A to reduce impact when she has to hammer bracelets in a pancake die. It is hurting her wrists. Are you aware of anything similar but about half the power? Keep looking but just keep coming back to Durston or Cookson Gold".

I'm not btw sure on the material she's using. Copper or silver at a guess.

He then sent me this link for one of these:

Hydraulic Press For Disc Cutter 8 Tonne

Durable machine for pressing and punching techniques Ideal for bending punching riveting and squeezing Four fixing points on base Can.. - Product Code : 999 HP01 , Price : 170.69 GBP

Rather than that I suggested something like this if he goes that route. Thinking a long pull down lever better than cranking a jack:

That to me is more pressing than hammering. I did think a literal powered hammer but the issue is that she has to lift it, so more stress on her wrist. Something like this:

Milwaukee do an M12 one which looks nice but quite a handful for her I think.

Any thoughts on a desktop planisher(?) or similar? Almost wants a sewing machine like action and adjustable force.

Cheers

How about a small fly press? Very controllable and quick to operate with minimal manipulation of the wrist/hand.

If very light duties, a little Ornstin button press might work.

Air operated toggle press arrangement, with a foot pedal trigger ?

Is there such a thing as a foot operated hammer?, basically a spring return hammer on a pivot with a chain/cable to a foot pedal. The hard work would be done with her leg while the workpiece is manipulated by her hands.

here you are powered hammer

here you are powered hammer

Did you read the bit about needing it for jewellry?

If you are going to post videos, please address the issue of how the ideas shown therein could be adapted to the actual application being discussed.

You would be better finding a video of the actual operation the lady is performing, done with a traditional hammer. That way everybody, including you, would understand the size, frequency and nature of the percussive effort required.

I visualised this a few minutes ago.
You beat me to it.
Elastic or spring to raise the hammer head. 2nd version had the pedal raise the hammer and the spring power the impact.
3rd version had a wheel with multiple small hammers on pivots.
4th version...........




OK.
Back to work

i have done via the very first video a tin hammer old style

then i showed a power hammer that can be adjusted to make it smaller for jewelery application

and to finish off ive provided a foot powered option using twin pedal foot motion to provide the spinning application

all you need to do is open your mind up and see what can be adjusted or made smaller for the applied application

the plannishing hammer is electric whilst maybe too big for the application but the powered hammer can be made very much smaller whilst using different heads for flattening or for fine work all done with inserts at the bottom with the hammer

How about a miniature version of a trip hammer ?
Electric motor runs a cam, cam trips a suitable sized hammer for the work she wants to do.
Could have the electric motor controlled by a foot switch so she has her hands free to manipulate the work item ?
Maybe have the trip arm holding one of her jewellery hammers ?

 

[Onoff]

Apparently this is something like what she wants to do. If that's the case then it's a press job. Can't see the need for a hammer?

I'm thinking the dies could be 3D printed.

Vibration from powered stuff might be best avoided if she is getting pain, I imagine an arbor press sort will do everything needed for jewelery.

 

[gaz1]

could you find them cheaper

ebay link to dies

Pardon our interruption...
