Micro motor question

[art925]

Hi all,
I appreciate this topic has been done to death on the forum I lost many hours last night using the search function. However, I do have a very specific question. Would one of the look-a-likey 100Euro micro motors be suitable to take a hammer hand piece? I know a number of members have these and they serve a purpose, it would only be required for setting.
Thanks
Les

Hi Les, I have been unable to find that micromotor on line in UK, so all I can say is that if they sell a hammer handpiece for it you can be fairly confident it will work.

You can also consider saving £££ by adapting a cheap vibrating engraver to do this, simply by reversing the point and shaping it to suit. You can use 3.50mm rod, or the stem of a drill bit to make more shapes.

My picture shows the Dremel, which is still a bit fierce even at its lowest setting, so I inserted an in-line dimmer switch for a standard lamp to reduce it further. Regards,Dennis

Don’t know if you can actually read this screenshot Les. It came up on the British Jewellers page on Fb which I don’t think you do. Marathon or an even cheaper Chinese equivelant which I can get the details of if you’re interested and can’t read this.
Took out some of the points

Marathon N8
Or the Shiyang N8 which is the Chinese copy, essentially made in the same factory. It has pressure sensitivity which means if you press hard enough to slow it down, it ups the power to compensate.
They also have a protection cutout if pushing the handpiece too hard.
All the handpieces, weather actually Marathon or copy are pretty much interchangeable and come with tools for taking apart for maintenance and spare motor brushes for when they might wear out.
Chiyoda Hans Engine C-33, they are expensive but a superb Tool, I have six of them.never had a problem.

What is it you have six of, Caroline?

[CJ57]

Oh not me Dennis, i was taking it out of the a post on the British Jewellers page on Fb . A chiyoda hans engine c 33. I’m not sure why he has 6 of them, he either has a big workshop or a lot of hands!

Thanks Dennis & Caroline, good feedback there. So Dennis you modified your engraver by cutting the power cable and inserting a dimmer switch to slow the motor down further? That's worth a try.

Dennis , you are as always a FIND for everyone!!!!! I am curious now abt using Dremel, I am not good at modifying tools though.... would dremel engraver work as hammer piece without dimmer switch? or any other machine? I have marathon micro motor but I do not think it has engraving function... , at mom not keen to buy expensive equipment too...

You've just reminded me that I bought a cheap engraver to try this out and still haven't played with it. Must remedy that.

So I am happy to say that apart from the infernal noise it makes, I have modified my engraver and it is now a setters hammer and it is perfect. I have rounded off the point and polished it to a shine because I will never use it for engraving and now can set a stone in seconds. I have not as of yet completed the electrical modification as you suggested Dennis, I am too busy with assignments right now, that can come when I am not as busy.
Thanks!!

Thank you for the feedback, Les. I am always afraid of leading people astray.
Now we only have to choose between the painful noise (slightly improved with modification) and the painful price of a more sophisticated one.

I should also mention, that the stems of a cheap 3.00mm drill bits from your local ironmonger will provide you with material for alternative points. They can be annealed for cutting and hammering and don't have to be re-hardened. Dennis.
