Thanks guys. Spent a bit more time this morning playing with the setup. I thing the bit was slipping in the collet yesterday? .002"doc, 7ipm feed and 54,000rpm. The top engraving was done with a very fine endmill .5mm? The second was cut with a three sided 30 degree tool. The engraving is .135" tall on aluminium plate. I did flatten the stock on my shaper to make sure there wasn't an issue with surface irregularity.

And yes my girlfriends last name is Steele

I'd love to see that 3 sided 30° tool.
Nice looking engraving Shawn.

Very nice Shawn,
54000 rpm that's quick

Thanks guys

The grinder is advertised as 54,000 rpm but I have no real idea how fast it is. I can't tell the difference in the engraving between the lowest and highest setting so I just use the low speed to save on air.

Steve, these are similar to the bits I'm have, I ordered mine from china and they were cheap but I only plan to engrave plastic and aluminum.

They look nicely made
