Laser Engraving/Cutting and Turnings *LINK*

>Texturing, piercing and carving/eroding are showing up on more and more pieces - in woodturning magazines, web sites and demonstrations - as turning trends more and more towards "post lathe enhancments" of "mulit-media" pieces. Classic shapes and hollow forms seem to be running out of "new" and really interesting woods suitable for these turned objects are becoming harder and harder to lay your hands on - or VERY expensive. The "segmented" area, and inlaying have an almost inexhaustible area to grow in, but the time, skill and effort involved preclude them as possibilities for many turners.

It's the time, effort and skill things that keep many turners from exploring "post lathe enhancements". Who has the time - or patience -to learn to carve or inlay really well?

As new tools become available, or tools from other disciplines are "discovered", some turners will begin experimenting with them, looking for ways to adapt them to their turnings - wood burning/scorching, dental burs, die grinder burs - chainsaws (scaled WAY down of course), new turnable materials, etc.. Their initial efforts are often quite

primitive, more investigations than fully developed integral components of a turned then "enhanced" work. Initial reactions to these early explorations are often - well let's just say - unfavorable.

I've recently been introduced to a new tool that has great potential for "post lathe enhancment" of turnings - a laser engraver / cutter. This new tool can "print" images on wood, engrave into wood, pierce through wood - and shape wood, albeit within a limited range - AND any combinations of these abilities. The possibilities are almost endless - constrained mainly by the "depth of focus" of the laser beam and the curvature of the turning - and of course, the imagination of the user.

I posted this url earlier to several turning forums - inlcluding this one. Have added some about this 3-D "carving" since the earlier post. That's at the bottom of this page

http:/www.svwoodturners.orgPieceOfTheMonth/ScottLandon/SLandonIndexingJig.html

Not surprising, some saw the tool as merely a way to burn "clip art" or a baby picture into a picture on a piece of wood - Ho-Hum! Others saw it as "cheating" - no skill or artistry required - offensive to their sense of aesthetics - overlooking the significant reduction in often risky grunt work. (Ever spent a few hours cleaning out the "background field" of a carving? That can be very relaxing - or VERY tedious.)

But let's take some of the works of a turner many are familiar with - Andi Wolfe. She's doing some beautiful leaf and botanical motiffs on her turnings - minimal carving, color providing depth and tone. Now imagine one her pieces with actual low relief carving, maybe including veins in the leaf in addition to the stems and major veins - and THEN she adds the fall colors. She's drawing the leaves anyway - so why not "draw" them on a layer of an image of her turning and have the laser "print" her drawing on her turning? Save the hand carving time for coloring!

Wonder how woodturners with a tendency for exploring will be using lasers in the next few years - when Ginkos and Copy Centers make them available to those that lack "deep pockets"?

>Sounds like a Infomercial charlie.

I'm the one who mentioned clip art, you seem to have forgotten the first sentence in my post.

>I see lasers as just another tool in our arsenal. Nothing more. Nothing less. I cannot see it making up for bad form or a lack of turning skill. Burning, colouring, texturing and piercing are all the same...more tools. I certainly appreciate the efforts of those who carve/burn/colour etc using hand-held tools as opposed to letting a computer take over but if they (the makers and/or their customers) are happy, so be it.

Only my thoughts.

Interesting, but ...

>for me, it's getting away from the reasons I want to be in my shop. The ability to create things with my own hands is what I need after 9-10 hours with a laptop, the internet, and e-mail.

I saw a computer controlled carving machine at the woodworking show I was at a few weeks ago. This thing took a thin panel of wood, and could carve any pattern into it at all with remarkable detail. They had a piece of thin wood with a photo realistic carving of two people sitting on a stoop of a house. You could see the roses on the porch and shirt buttons. Incredible, but not for me.

Undoubtedly, the carving and laser technology that is being built for the wooden world is going to make certain things more attainable to the masses. If I had to carve some of my textures by hand vs. a die grinder or Dremel, I doubt I'd do all that much texturing. There will be very cool applications of the technology (imagine Art Liestman's Puzzle vessels actually coming apart!), but I'm not dying to have one.

Still, good read through, though!

>Apologies if my heads up on a potentially useful tool came acrossed as an infommercial, I certainly ain't selling anything. I have no affiliation with anyone making or selling laser engravers. When I find a tool I find interesting and get a feel for it from a user's perspective, rather than from reading brochures or watching a demonstration at a show, I share what I've found in the hope that i the info might be useful to another woodworker.

Regarding hand work and power assisted work, I learned to handcut half blind and through dovetails and do them either for a special One Off or just for the pleasure of cutting them. But when I have four or five drawers to make I'm going to set up the router, bit and dovetail jig - a variable spaced dovetail jig. If I only need to stock prep a couple of boards for a box I'll more often than not get out a handplane or two. But If I've got 20 bf to prep I'm off to the joiner, planer and table saw.

Maybe it's because I've been playing with computers and computer graphics and CAD for years, I often do the creative sketching and some plans on my computer. With a tablet and pen I can free hand sketches and drawings and use the computer to variations without having to redraw anything. In part because even my hand printing only borders on legible, I "write" using my computer rather than using a typewriter. The "basket weave" pattern and the variation on the linked page took about an hour to do - most of that time figuring out how to do the shading for the basket weave. I chose that subject to investigate what it takes to do a gray scale image that could be used for "low relief carving" using a laser. Most of that time was spent on the original image - the variations took only minutes to create.

I'm seeing laser engravers as possible tools to enable me to make things I can see in my mind but can't yet make in the real world - and not for any mass production or limited editions. But I like the idea of being able to do variations fairly quickly, again not for commercial purposes but just to see them in the real world.

If I came acrossed as hyper-enthusiastic - apologies. But this laser idea has my creative joices flowing and I guess my cup ranneth over, or in this case - my keyboard.

>Charlie, I love what you are doing. I agree that a laser cutting machine can be an assett to woodturning. To each his own. However, the equipment cost puts it out of reach for me and I think others.

Keep playing.

>I agree with Steve. It's simply another tool. It can be abused or it can be used to create something special. From an art standpoint the final product is the most important part. How you got there doesn't always concern me if the piece works. Would I use one. Sure if I could afford it. It would be fun to play with. I've used a milling machine on a few pieces. I could have done the work by hand but it was faster by machine and the final product was just as good.

Now I'm not saying there's anything wrong with being a turning purist . It's kind of like the argument between using hand carving tools or power carving. Each person works the way that pleases them or accomplishes what they are trying to do.

>No apologies necessary Charlie. If it wasn't for a "fire" in the gut for our craft, we might just as well sit on our butt and watch Dancing with the Stars. I have a 25 watt Universal with a rotary attachment. Every time I fire that thing off I get a smile on my face. I've always had a thing for accuracy and tools, and a computer driven laser has both in spades! Thanks for sharing your ideas, and your passion!

No apologies required?

>I wasn't saying that lasers are bad or wrong. I merely mentioned that I don't turn with the intention of producing a maching made object. I can see that you can certainly envision uses for a laser to guide cutting and surface decorations, but for me the main reason I go out to the garage is to get away from my laptop and technology and do something with my hands.

It's a personal choice that I make to not have the machine execute the work for me, even if I have programmed the steps. For me, it's not as much about the object as it is the path that I must travel when I make something.

There was a time when I could only hollow through a 1" hole to a "heavy quarter" inch wall. Today, I'm pushing 1/2" holes down less than 1/8". If I had a CNC cutter on the tip and was hollowing with a program, I'd probably make more/better consistent objects, but I'd lose interest because I become less involved in the production.

Lasers to cut and pattern are an interesting tool, but I see them like I see ornamental turning. The turner has control over what happens, but isn't really in control of the process. The machine is doing the "hard part"- which is marrying the turners vision and skill into the final object.

Still an interesting read, though.

Thanks for posting.
