You say laser cut pieces. Are you meaning laser or plasma? I've seen plasma cutters that cut sheet steel and I've looked at lasers for that but the cost of the lasers is just out of this world. What sort of a set up do you have?
Out of this world is relative...LOL
I DO mean laser cut,but not by me personally. I mean outsourced to a facility that is set up to do that exclusively.
They are expensive machines to be sure and require constant care and maintenance as well as a competent programmer to do the computer work to control the beast. But it is more accurate and accomplishes a finer kerf or cut than plasma cutting.
I also have allot of my very intricate designs WATERJET CUT (the newest technology). This method does not burn the edge the way laser cutting does,so there is zero heat distortion of the piece.Also you can't laser cut bronze or copper in any thickness as the light reflects back and burns out the laser. So the waterjet method is the alternative.
The laser cut pieces for this fruit bowl were the left over SCRAP from cutting these curly shapes from big sheets of metal(used as decorative screens at a Nordstroms someplace). I just saw the potential for using them in this way,cold formed them to the requisite curve and welded them together...
Very true, I think the machines I saw for laser cutting any sort of thickness of metal started at about 150K to me that is out of this world for a machine that I wouldn't be using at least 12-15 hours everyday. And since I've not got that sort of budget for a machine period nor do I want to spend all my time cutting metal it is totally out of the question. Ok so you outsource it that makes more sense. Interesting that copper and bronze are more reflective than stainless? The waterjet sounds interesting. Is there some abrasive in the water or just water? Sounds pretty wet and wild to me. At least heat shouldn't be a big issue either. I always wondered about melting the metals with laser but figured that you would end up with a nice smooth edge since it was burned through. But it leaves an undesirable burn? Hmm very interesting. My big problem is I'm interested in too many things and don't have time for trying them all nor the funds to experiment with so many things. I'm a porcelain person myself and have lots of experience with that but still learning even there. Have done a bit of metal smithing, some casting, etc. and lots and lots of reading about things. You do some very cool art.
Thank you again Marsha,
The water jet has a slury of microscopic garnets which are shot at high pressure through a very tiny aperture. It cuts 1 inch glass like butter. Stone,stainless,masonry,pretty much anything...
the problem with the laser is that it leaves a very sharp edge often,that needs to be ground or polished ,as well as the heat thing.
There is also laser welding now which I need to learn a bit more about.
