Nice point Randall:)
Got me thinking it might be nice for etching a hardwood floor or hallway
Chips was my first concern, when I was remembering a large(6') Compass Rose inlay a homeowner up here had done in a antique refinished Sugar Maple floor.
Had a friend spend the better part of a day inserting a 12" Ebony "Toe Line" in a Jatoba floor for his dartboard..he MIGHT have hired someone after all the cussing he did
I imagine a large fan or compressor nozzle gun could keep an area clean of chips though?
Too bad it can't climb walls:)
A lot of people refurb timber framed barns and houses to live in here, that might want designs in the timbers.
Just thinking before coffee:)
