I assume as it's possible to cut these with a TCT handsaw, doing it on the CNC would be no problem - but does anyone have any ideas of things like best tooling, spindle speed and DOC/feedrates please? cheers.

Is an Aztec calendar on the cards?

Sadly not - just some arkward shaped bits of "stonework" for the house.

What type of block ?
Are they lightweight Celcon or similar ?
If it's not a big job you will be able to machine Celcon with ordinary TCT cutters, you will have to play /experiment with feed and speed.
Fag packet sketch would be helpfull.

Yes Mike, Celcon Standard or Solar grade blocks or equivalent. I don't have any sketches yet, but basically its curved top bits and side trims for arched top windows/doorways. Maybe I'll buy a cheap cutter or two and see how I get on - it will mean improving the dust covers on the machine a bit too, as I can see this would generate A LOT of dust, and abrasive dust at that - that was always on the list of improvements to do anyway.
