Here is rock number 2
It's still wet so not too much contrast yet.
Kong this was done at a feedrate of 1000mm/min,it would probably do 4 times this but i can't nip my bum cheeks any tighter if you get my drift!!!!.

Just call me Fred Flinstone.
I never in a million years thought my wood router would cut this with no problems.
This is really opening my options up.
The renishaw probe made this uneven rock a boon to draw and cut.

Just another view to show the contour of this thing.

Mark,
ok how are you getting the router to follow the contour of the stone? I am wanting to do something like that but am having trouble figuring out how to get the router to compensate for the varience in the surface. Thanks Ron
Ron
I probe the surface of the rock first and read it into my cad cam system then project the toolpaths on to it.Then post back out to mach2 and machine.Mach2 makes a superb job of probing and machining,But i think it screwed my router bearings.
Maybe just Crap bearings.I will check tomorrow.

Mark,
What are you milling the stone with? Wet?
I tried engraving a piece of granite tile. I put water on it and it still lit up my carbide cutter. It was just an experiment though. I guess diamond cutters are the only way.
Thanks,
Chris

The stone was just wet off washing,It was cut dry with carbide with no problems.The cutter was just a 6mm shank with a 4 sided point ground on it (like a pyramid).

Hi Fellas
Just getting back to my machine after months of other problems.I am going to build a congreve clock on the machine next See link for example.(http://www.williamcongreve.com/).
Thought i would maybe cut all the parts in one go ie,place sheets of brass on table 1/16" thick,3/32" thick etc.
Although the turned parts would have to be done on the planned cnc lathe.
Just tried a bit aluminium 1/16" thick and cut an example , it worked a treat.
I was thinking of maybe serializing my efforts on the zone if admin would maybe tell me where or which section/forum.
I need to get some serious cnc'ing done i think i got withdrawal symptoms.

Good to have you back Mark, I am sure the boss would love it if you would write it in the form of an article, which could then be posted in the articles section somehow! There was a post a little while ago asking for articles, but I lost track of where it is
(Note: The opinions expressed in this post are my own and are not necessarily those of CNCzone and its management)
How'd you hold that thing down to cut it?

I cut the inside first by clampng around outside then milled around the outside and left snap offs (Bridges) in 4 places about .004" thick so the job did not fall out.Then when complete you just press the job out of the plate.

Well i am taking the plunge and designing my own website around my homebuilt cnc router and my clockmaking projects.This is going to take up an awful lot of my time so i will be looking at the amount of visitors to my site and any feedback to see how far i should take this thing.
http://website.lineone.net/~rmtucker/
I am also hoping to update and give better descriptions of the building of the cnc to help some of the newbies out there.
Cnc Zone has been a source of invaluable help and encouragement to me and would like to thank all who answered and put up with my dumb questions.
I would say that i have finished the Cnc except for an operator panel and handwheel.
Please Remember that the website is under construction and will be changing on a daily basis so your patiance would be appreciated.
Once again thanks to all and i will still be lurking around the cnc zone every day.
Regards
Mark

Looks good, and I would like to see more about the Congreve clock you have shown. The history page just displays the word "History." :-) Of course, I'm a clock nut.
It looks like a very good beginning to a very good site.
Say, how did you engrave that rock? Did you design a toolpath to follow its contours? It looks like you followed the surface down the "step."
-- Chuck Knight
Mark,
I am also quite interested in your clock. I knew about Congreve's rockets because you launched them against us nearly 200 years ago :-) but didn't know he invented a clock. I looked up his clock, and it is a most interesting design. I had never heard of a rolling ball clock before. It must be interesting to watch one in operation. I will eagerly watch your progress on your web site.

Hi Guys
Just follow the congreve project links on my website to see progress on the congreve clock.

Hi guys
I have found a use for my cnc router at last,Go to my web page at:-
www.weardalecnccarving.co.uk
in the march and april sections of the vwtrike build.
It may not look much at the moment but when i start on the engraving,the yokes and anything else i can fit on the machine will be covered.
It May give someone some ideas.
Regards
