RE: [CAD_CAM_EDM_DRO] Project on a miniscule budget

Sorry, my bad read.

I’d try to find a standard somewhere to use. Like maybe HYPERLINK
"http://www.smallparts.com/"www.smallparts.com where they have a number of
oddball tubes in brass, stainless and steel.

It would seem that building even a small EDM would cost more than buying a
standard and modifying. Like broaching a slightly smaller hole to the size
require for the cost of material and a broach.

He did say a square bar.

First off, a .1875 square will not fit inside of a .250 diameter, lapped or
otherwise.

After that you might try Reid Tool Supply: HYPERLINK
"HYPERLINK
"https://reidecom.reidtool.com/xephr/edit/ITEM_GROUP_DETAIL?query=*CATALOG_I
"https://reidecom.-reidtool.-com/xephr/-edit/ITEM_-GROUP_DETAIL?-query=*CATA

OG_ID=RF118&-query=*ITEM_-NO=SHS-18&-query=*GROUP_-ID=100583&-query=*START_-

Where you'll find a .3125 diameter with a .1915 square sleeve, 1 ½ inches
long for $10.35 USD.

Here's one to challenge all of you!

I need to put a 0.1875" square hole along a 1.25 inch length of a
0.250" square BMS bar. I need this hole to be a lapped or precision
fit on 0.1875" square bronze slipper. Fabrication using silver
soldered joints is a possibility but so far I have not been able to
produce these components with the fine finish I need for the job...
An EDM machine came to mind and I would like to have a go at making a
simple one if that's possible.
I am retired here in the UK and have little spare cash but as an ex
audio engineer and film sound recordist I do have some knowledge of
electronics.
I know there was a circuit for a very simple machine in Model
Engineer magazine many years ago (1970's I think) but tracking the
issue and a copy down has been fruitless so far even through the now
owners of the publication.
I believe the designers name was Roy Amsbury who worked for Rolls
Royce in Derby but I have been told he passed away some years ago.
Just wondered if anyone has a simple EDM machine design that they
might be prepared to let me have. Could be an interesting project to
pass the time away with.
Regards to all
Paul Miles.
