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.
I thought there must be some sort of abrasive in that water jet. So is the water re-captured and re-used as well? This water jet sounds like a pretty cool piece of equipment I suppose its god awful expensive too. You have this one or contract that out too? Gee nothing like 40 questions. Sorry I'm a curious sort.
I saw a little laser spot welding thing at the Rio 'Catalog in Motion' year before last and it was a pretty cool little machine. Looked like a breeze to use. But even just the little table top one they had there was like $10K I could see how if I had a big jewelry shop or something it could easily pay for itself. Much quicker and more secure than soldering, no danger of melting anything. Worked more akin to a fancy electric stapler. You just put the stuff under the spot and push the button and zap all done. It was just too cool. Or maybe I should say hot. Of course it was just doing spots I'm sure they also have ones that would weld continuous lines and the like but they probably aren't really jewelry tools so wouldn't be shown at that sort of a show.
Yes the water is recycled,and I farm out allot of stuff for that. It's actually a little less expensive than laser cutting. The machine was $150,000 I think.
Laser welding machines are still too expensive for anything but production work ,but like all solid state electronic devices,they start high but after a few years the prices fall pretty dramatically.
There's really ALLOT of new trick technology for metal fabrication. I try to stay on top of it but it changes so rapidly and most of it is for production work not for art...FABRICATOR MAGAZINE is a wealth of info but it's all industrial...
Sorry, got confused on which piece we were talking about.
THESE parts are scrap from laser cutting. These are also drops ie what's left after the sheet has been cut.
So one can imagine this large sheet of stainless with these shapes cut from it. They obviously begged for something to be made from them. They also cut the same shape from a steel sheet. I made the figure "Topographic Emotions" from those pieces.
Glad you asked ,because it reminds me,
I need some kind of new multi-track digital recorder. Four tracks would probably be enough.
I'm finally using my Korg Toneworks pedal effects unit to advantage,getting the heavier sounds I've wanted for some time.
I've got some really good pickups in all my acoustic guitars and can play late at night with headphones without disturbing my housemates.
Is there a decent relatively inexpensive recorder for multitracking you would recommend ?
I have a few questions for you are you on a mac or PC, because I have computer software I can send you a copy and all you would need is a audio interface, I have programs for them both Mac and PC. Before I can install Digital Performer on my MAC I have to upgrade the OS. Cubase is also a good program I have that for MAC / PC But I use Garageband all the time because like all these programs you can do sound on sound. I use a computer as apposed to a dat machine or a reel to reel. Check Craigslist for CA also and ebay. HarmonyCentral is a great place for product reviews. Get back to me when you can I will be home all day today 8/18/07
I've got a PC but it's maxed out because of my huge image files.
Music will take up too much space I think.
I (think) it would be more convenient to have a small recorder wouldn't it? plus I play in a different room than my office...
I have a friend who will GIVE me any audio program(he's a recording engineer). I should ask his advice too.
I was offering because most of the time others have helped me so I like to do for others as things were done for me. But yes talk with your friend have him make some suggestions on your set up and what and how because with the computer you don't loose the highs and the lows that you do on tape. Well hears a great book for you "sound Recording Advice" By J. J. Volanski. Awesome book! Peter
Thank you as always Peter,
I'm doing so much layering ,it might not even matter if I lost some highs and lows ,but my friend will certainly know.
There are so many parallels with what I do to photography.
By the way I just bought a new Olympus 770 SW strictly for pool shoots. I can't wait to use it...
Funny that you say this because I find that weather it is music, art or whatever the process is very much the same. Good luck and I wish you loads of fun and creativity with your new camera. I look forward to the next work you post, I really enjoy what you do...
