My mother has a 15 year old dog that she is going to have to euthanize before long due to health problems. She wants me to make some sort of marker for the grave. I decided aluminum would be best, so I bought a couple 6x12x.25 plates of 6061. I used one of them to do a little practice, and the results were mixed.
The drag engraving always turns out good, but it doesn’t have a deep enough relief for what I think the projects really needs. The V bit does, but I don’t know what all I did wrong. I used a whiteside .25 90 degree carbide bit, and used the quick engrave function to carve at .0125 (I think it went deeper than that though). I noticed the lines were jagged. my settings were 30 ipm feed, 30 ipm plunge, and I had the router turned all the way up probably running 25000 RPM.
If anyone known what went wrong let me know. Another theory I have is maybe the V Wheels on the machine need to be tightened, and maybe the belt too. It is pretty cold in my garage right now. Let me know what you think. Thanks.
