Lug Engraving - Test 3


jmb

Recommended Posts

I finally got all the pieces parts and additional electronics scrounged to build and add a 4th axis to my engraver.  This is something I've wanted to do for quite a while but never had the time to spend on it.

 

Once all of the parts got here I had to replace the 3 axis interface in my controller and add a driver for the 4th axis motor.  After I had that debugged I slapped together a simple rotary axis, hooked everything together, and surprisingly it actually worked!  After some tweaking I gave it a try this morning and here is the results of my first test on a test piece of stainless stock.  I have some more experimenting to do but I think I'm almost there. :)

 

Further down in the thread are pics of the engraving on a case...

I loaded up a beat up case and tried "for real" on this test - I think we have a winner!  Probably could have went about .001" deeper but all-in-all I'm pretty happy with it.

So, is it the general consensus that the very lightly engraved looks better/more authentic than the deeper engraved?

 

I think it depends on when. The early 1950s 'Brevet' look almost hand scribed in pictures, while the later 'Registered' 1950s look lightly engraved. I think the two you show are quite close to being correct for the later 1970s, `80s and since.
