Very nice work, indeed! I've cut aluminum one time and had the wrong bit so it didn't work out very well. How does bronze cut compared to aluminum?

David
Hi David, I've still got a lot to learn.
I broke 3 or 4 endmills on my first attempt at aluminum. It's really counterintuitive to see bits snapping at 20ipm and people saying "You're going way to slow!!" But they were right! I went up to 100ipm and no more broken bits. (Kinda like swinging an Axe vs trying to push it through the tree.)
Also, The heat is displaced with the chips so at 20ipm I was boiling the WD-40 and charring the spoil board and weakening the bit. At 100ipm no heat at all.
Aluminum vs Bronze = Pine vs Maple.
I don't use any lubricant on Bronze and it doesn't even get warm.
I was trying to think of a way to incorporate metal into a wood project, like an inlay but I think it would just end up looking like stick-on letters???

What about a small mister, like Fog Buster or similar?

Need them chips to clear w/ Alum.

Dont do an inlay... let the metal object(s) protrude the surface. 1/2 in/out
Maybe run a horizontal grain in the letters on a belt sander. They get hot fast.

Wow... too bad you couldnt flood coat it in paint... then bring to a stroke sander
to finish off the letter tops.

Joe, Very nice work on the bronze plaque! Thanks for providing the info on milling. I have a similar project I've wanted to tackle for 3 pet memorials and have been hesitant to try it.

Yep, painting it then sanding the letter tops and bevel this afternoon, then "JB weld" it to the granite.
Stroke sander? In my shop it's a block of wood with some 220 grit wrapped around it. 🙂

Go for it!! I just got a cheap box of 1/8" 2 flute endmills (those 10 for $10 on Amazon) and started cutting. I'll be getting an Uglysign mister someday, but for now it's just a can of WD-40 and my air hose. 👍

I'm thinking about sinking a 90deg vbit into a piece of black granite without water and just see how that goes. We'll see!! 🙂

I have 3 pieces of 18" X 18" X 1.5" soapstone I'd like to try with a vbit.

I cut Corian with just a regular Vcarve bit. No lubricant. Just use an old dull one cause the tip will be history after a bit (no pun intended).
