Carving in marble

[DavidWestley]

Ok, in the interests of making something other than sawdust, I thought I'd have a go at engraving marble.

Slab of white marble 400x300x15.

Bit was a 90 degree carbide bit (my favourite bit - which is one of these http://www.toolstoday.com/p-6015-in-tec ... r-bit.aspx),

Max depth per pass 0.5mm,

Stepover 5%, Feed rate 50" per min.

DeWalt router running on speed setting "4".

Cut dry (my MDF wasteboard isn't waterproof).

The whole job took approx 30 mins to carve. Minimal dust - my rudimentary dust collection system worked perfectly. Also there is no sanding or clean-up required.

The cut was then filled with black=tinted, 2 part resin. I think I preferred the raw, unfilled version, however as a cutting board or cheese board, I suspect it'd quickly fill with gunk.

WOW!

It says the bit is for: • Ideal for routing softwood/hardwood and harder materials such as MDF & Chipboard

I would have thought marble would be pretty hard.

That looks great, was there any damage to the bit? Now I am interested in trying this, thanks for sharing.

Thanks for the GREAT idea!!!

Hope you don't mind me making some of my own. Got some friends that need one.
