First Try at Engraving Al
I am using some coated engraving bits I bought on eBay (1/8" shank 30° 0.008 tip). The aluminum is some of the flat stock from Lowe's (no idea what that is). This is set to go 0.010 deep. I believe I did that in two passes. The bar was taped to a piece of MDF that was screwed to the spoil board. RPM was max and the feed rate was 45 ipm I believe. No issues. Turned out pretty good overall. I realized after the cut that my work piece was a little out of alignment. Piece is 0.750 x 6 1/4. I did have a decent burr everywhere. Not sure if that is a speed/feed issue or the bit? The burr was removed with 220 very easily. I filled the groove in with enamel hobby paint. I would have liked to hatch the interior, but that was going to take too long. I kind of like this look anyway. Just playing and learning. I attached the plate to my base for fun.
Why hammer. At work (many years ago), I was the lone mechanical engineer amongst a team of EE's and programmers, so they always teased me about "get a bigger hammer" and gave me the nickname. It stuck.

Re: First Try at Engraving Al
Nice logo. FYI I believe that the cheap home center aluminum is most likely 6063 alloy, which isn't as nice to machine as 6061.
Re: First Try at Engraving Al
Wow...that's great and even better because of the alloy!
