A New Surface Treatment Tool For Turners - Laser Engravers
Turners have come up with all sorts of ways to add patterns and textures to their turnings - rotary tools with burs and bits, pyrography pens, wood vaporizers / branders, sand blasting, etc.. Now there's a new "surface treatment" tool available to woodworkers - LASERS - speciifically LASER ENGRAVERS.
Laser engravers are becoming more accessible and they offer a lot of interesting "surface treatment" possibilities. They can "print" images on just about anything. They can pierce/cut through just about anything. AND - they can do LOW RELIEF 3D "carving" using "grayness" to determine the depth of cut - the darker the gray - the deeper it burns.
Here are some examples of low relief 3D "carving" done with a laser engraver - on/in wood - flat wood AND curved wood. You'll be seeing more about them and how they were done later.
The intent of what follows is to give YOU an overview of a laser engraver and what it can do - AND - provide you information that should flatten you learning curve enough to get you started - successfully.
Here's the Table of Content for what we'll be covering. Go through it all and THEN you can get to specific topics as you need them later.
