Hello

Does anyone have details of design of the mechanical part of Mike Napps spark eroder. That was on show at the recent Warwick Show

Regards

Norman

Hi, if you are a member of SMEE, Mike will gladly share the details of the device.

 

This is not a simple design and requires the programming of a microprocessor.

 

It is a very efficient design however, there is another route.

 

Ben Flemming has produced 2 designs for an EDM, one is RC based and the other is a more advanced pulse design, both of which use readily available components and do not require a micro or any programming.

 

Search Yahoo groups for EDMHomeBuilders for more details or PM me, as I have both of the books and PCB’s in build if you require any further info

 

regards

Not sure if I have the correct reference, but Mike Kapp (with a K, not N), published a simple EDM design here not long ago – I built a version which works well enough for me.

It is not a processor controlled system – uses a simple CMOS control circuit. The series of 4 articles gives all constructional details, and the thinking behind it, if you want to change things.

I have seen similar postings for a while now and have tried to build my own machine without success. I came across Pear Tree Engineering ( http://www.sparkeroding.co.uk ) to whom I posted a shaft with a broken tap which they removed sucvessfully.
It seems an easier and cheaper way than trying to build a machine whose performance may be doubtful.

Hope information is useful, Jack

Probably as the post is 2 years old!! MEwebsite has been changed about recently with a lot of projects taken off and only available on DVD

Thanks for the info. Jason

"…lot of projects taken off and only available on DVD"

Hoping – and I apologize for my intrusion on the thread – the moderator would provide details about the dvd (what it is, contents, how to order, cost, etc). Thank you
