Does anyone do woodturning with replaceable bits instead or in combination to resharpenable tools? For example, I’m familiar with indexable bits commonly used with metal working lathes – is there anything similar to this for wood working? I’m doing some projects with my mini-lathe where I’d like the functionality of my metal type tool holder for straight lines. <o:p></o:p> |

I've used this one: http://www.rockler.com/product.cfm?page=29075&site=ROCKLER
There are others, such as: http://www.knotsburls.com/kilian-tools.php I like the one I use, don't have to worry about resharpening, just loosen the screw, rotate the cutter a bit, and retighten the screw. |

Yes. Go to penn state industries and look up their duplicating machines. This is exactly what you are describing.
ETA, here's the link duplicator attachments |

My observation is that the metal working tools are slowly making their way into the woodturning world as people get more familiar with the capabilities...and also for convenience. Carbide inserts are a driving factor. You can find already find replaceable carbide tips in hollowing tools like the Sorby Sovereign system. I've seen square and round inserts marketed directly to woodworkers as well. Personally, I've used metal working bits on many occasions and use them without reservation. You can hand hold the bit holder or make something longer and more suitable for a wood turning tool rest. I keep telling myself I'm going to make some kind of nice aluminum handle, but I've yet to get around to it. |

Like most things the correct answer is- It depends. Main problem with bit tools is getting a good tool angle to the wood so you shear the wood fibers instead of tearing/abrading them. Tight grained wood like birch or maple is more forgiving of improper tool application than softer ring porous species. Finished profile also dictates bit size and use. When I taught adult ed woodworking, the most difficult students were machinists. They could only approach the project like, well, machinists. Wood and metal are different. |
