Laser etched Flag stone

Our local Trail Life Troop (Christian Alternative to Boy Scouts) is building a stair way for awards and such out of local flag stone. I was asked to mark one of the pieces.
I think it came out nicely. :grin:

What a lovely idea! That turned out great! :smiley:


#3

Wow, that turned out great. I have a flagstone path in the yard. I may have to pull up a few before the Wisconsin snow and frost sets in during November. I won’t want to wait until Spring to try this.

How many watts is your laser?


#5

Is it actually ‘etched’ as in layers of the stone blasted off by the laser? Or is it something like Thermark?
What kind of power laser is it? Oh, and how long did it take to actually laser it? Just a couple questions :wink:

Very nice work.


#6

I used my 35 wt laser but honestly, the laser tube is going on that one so it was probably closer to 25wt.


#7

That’s very cool!


#8

Oh I want to do that. Well, not exactly, because Troop OK-0339 doesn’t live in my back yard. That looks so great.


#9

that came out GREAT!!!. is it color change or is there some depth on that as well ? did you run the laser slow and hot or just let it rip at speed?

I love this


#10

Its a shallow etch…since flag stone is soft like sandstone. The color change is from melting the silica from what I understand. Hes going to put on a layer of urethane on top to weather better.


#11

I think the settings were 50% both speed and power but Ill check tomorrow when I get back to my office/shop


#12

That came out beautifully! I love it.


#13

Fantastic! Add flagstone to my wish list for materials. Maybe I’ll make some Pet Rocks (anybody remember that phase?).


#14

I loved Pet Rocks! Best marketing scheme ever! :relaxed:


#15

You’d probably be better off using thin river rocks. Thinner pieces of flag stone, that would fit in the GF, might be a bit brittle.
This particular piece was 3.5" thick and weighed 30+ lbs. :stuck_out_tongue_winking_eye:


#16

The layer of stain/oxide on the surface greatly increase the contrast, very nice!
I have some scrap multi-color slate I am anxious to work with. The colors, mostly shades of green come from mineral stain. Petroglyphs for the new age!

Thanks for showing that!:thumbsup:

Yeah I asked him for a dark piece…better contrast.
