I know I've seen some instances of results that people have had with cutting in corian, and I've just gotten in my first two pieces to try it out. And now, of course, I can't find those threads to study up on techniques. So questions:
1. Cutting to size - this is a 1/4" piece, so possible using a standard scroll saw might work or a table saw with a paneling type blade in it.
2. Finishing - I think I remember Bob did some finishing with 220 grit sandpaper. Is that right?
3. Bit - standard 1/50th bit on slow setting ok?

Rick, for cutting I used my Hitachi scroll saw which is the kind one would use for fretwork I think a table saw might be a bit tough to get good cuts from. Finishing was only needed to dress the edges nice and smooth from cutting out the piece 240/300 grit paper would do a good job. I did use 1/50" bit and slow setting, not sure if I needed to do slow setting but at least I know that this speed worked out well. The surface after carving is simply amazing how smooth it comes out, I needed to do nothing to the surface other than use a medium bristle brush to clean it off. |

Bob, you mentioned having done 1/4 size sheets. Do you remember what depth you cut to?

Rick, I believe 3.5 mm is the depth I chose which is rounded out to be .14" so a little more than half way thru the 1/4" thick stuff, unlike wood that will warp when carved over half way thru the corian does not warp.

Finally got around to cutting out a piece of corian, really surprised and happy overall with the results. My main problem is that, like when I do wood, I get tiny little lines in the final results. In this picture, they would run north to south and are tough to see if you look about six inches away from the piece (these would run right to left when cutting on the machine). With wood, it's easy to sand these out. In this stuff, from what I see on the internet, I'm going to try a little cleanser with abrasive (Softscrub) and a kitchen sponge with one abrasive side. Lightly sand and scratches in corian countertops are supposed to disappear. Anyone know anything that I can try to get rid of these lines? I did tighten down the table holders to get a smoother Y movement, which I did. Just wondering if I need to tighten it even more.   |

Rick, you can try decreasing the scan step setting when you run your image thru I-Picture, by default it is set at 0.2 mm if you set to 0.1 mm it will virtually eliminate those lines but your carve time will nearly double. When I did my corian pieces I used 5 x 7 corian and it really did not take that long using medium speed.

Thanks Bob, I wondered about decreasing the scan step but didn't know if that would do it. I just ordered some more corian off ebay, at $4 (delivered) for 6 each 10 x 13 x .5 pieces it's not much different than wood. I've already been commissioned to do a doggie headstone for my nephew - lmao. My carving (above) was on a 8 x 12 piece corian and on low speed it took 8.5 hours, I set it up first thing in the morning and came back for supper to clean up. The "sawdust" is an interesting byproduct, I saved a baggie of it to use as snow flecking on Christmas projects - now if the neighborhood kids just don't try to snort it in the meantime-it looks like a bag of cocaine.

 I took the piece out and tried the softscrub abrasive sponge idea - it might work if I had the dedication to do the work, but I'm lazy. So I took 220 grit sandpaper, wet the piece down completely and then hand sanded it with medium pressure and a circular motion keeping it wet, and 10 minutes later you can see the difference between the smooth and striped sections. Real happy with the results, I think corian works much like wood but you don't have to stain and clear coat it. |

Rick , the pieces I carved with the lower scan step needed nothing more than to use a stiff brush to clear off the shavings from carving, that might help you out in not having to do all that extra work.

If I drop the scan step in half, yet go up to normal from low speed, I should about break even in time with better results..........maybe.

the parts I cut with the minor scan phases required nothing more than to utilize a inflexible skirmish to head off the flakes from cut, that might assist you out in not having to do entire that additional work. |

I'm sitting here, while watching the food channel, thinking that I could cut patterns into the corian, coat it with PAM, and then pour chocolate into it to produce custom snacks. Might just have to try that.  |

Cut another piece after dropping the scan step to 0.1mm, the line problem is not 100% gone but it is much less than it was. I used a 1/32" bit this time on low speed, now I just need a good milk chocolate recipe to pour into this mold and we'll see if it works or not. |
