jmb Posted April 11, 2015 Report Share Posted April 11, 2015 I while back I picked up a conical diamond tip engraving bit in a spring-loaded carrier and today I finally had time to make an adapter so I could attach it to my engraver. I removed the spindle motor and mounted the the adapter in place and gave it a whirl. I also changed the gearing on my rotary axis from 3:1 to 5:1. The drag engraving is extremely precise and fine and the 5:1 gearing seems to have taking the "jagginess" out of diagonal lines. I need to contact the maker of these diamond points to see if I can change to a bit stronger spring inside the carrier to get it to cut deeper without damaging the diamond tip - somewhat expensive... Here's the results. 5 Quote Link to comment Share on other sites More sharing options...
cc33 Posted April 12, 2015 Report Share Posted April 12, 2015 Looks a lot better, just work on the depth like you mentioned and you've got it nailed Quote Link to comment Share on other sites More sharing options...
Frazzle1 Posted April 12, 2015 Report Share Posted April 12, 2015 Yup that looks a lot better and so be honest I don't think it will need to be much deeper either. Great work as always Justin! Quote Link to comment Share on other sites More sharing options...

GOATmaster Posted April 12, 2015 Report Share Posted April 12, 2015 Not bad. Not bad at all. Like you said, it just needs to be a little deeper then the engraving will be more pronounced. Looking forward to some updates! Quote Link to comment Share on other sites More sharing options...

Beachcomber Posted April 12, 2015 Report Share Posted April 12, 2015 To me that looks great, deeper maybe as mentioned before but other than that pretty much spot on! Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

jmb Posted April 13, 2015 Author Report Share Posted April 13, 2015 The seller advised me that the spring is adjustable a small amount but advised against putting a stronger spring as the tip could shatter if it was "dragged" over a rough spot. I will crank the spring all the way down on the next case but that is about the end of my experimenting. Quote Link to comment Share on other sites More sharing options...

Chuck P Posted April 13, 2015 Report Share Posted April 13, 2015 I honestly think if it is just a smidge deeper you have nailed it, and I bet you achieve that with this current spring because it isn't that far off...at least from my unprofessional, aging eyes on a photo viewed from my iphone.
