| Post subject: | Cutting rosette strips/logs |
There is a tutorial on Side grain rosettes at the link below and I have a question: viewtopic.php?f=10117&t=16350 In the first and second picture there are "cutoff" strips being used to form into a log. These strips are then glued together to form the logs. I understand the concept and how this works but what I don't understand is how to actually cut strips into different shapes (second picture in the tutorial) and how to shape them into perfectly shaped logs (4th picture in the tutorial). It also looks like the glued up log in picture 3 is cut into different shapes and reglued to form a new log in picture 4. How do you cut them the full length of the log maintaining that shape all the way down the log? There are further pictures with the endless martini rosette (very cool looking) and I just don't see how to maintain that shape all the way down the log. Any help is greatly appreciated. |

Sam, I did this tutorial with mostly older pictures of several different rosettes. I wasn't actually making a rosette at the time. But maybe I can answer some of your questions. I use a bandsaw to cut the ends of the scrap woods for angled pieces. I set the blade at the angle I want and then crosscut the pieces through. Sometimes I use double sided carpet tape to hold smaller wood pieces to another board and then rip saw it. The wood strips come out a little rough so I sand them on a flat surface to level them before gluing. Al Carruth has different jigs that he has made to plane the surfaces flat, which is probably more accurate. Maybe he'll chime in. Sometimes I glue up sheets of veneer and scrap before I cut off angled strips. That holds things together better. So yes, I often cut up pieces and reglue them until I have the log I want. This is where the double sided tape comes in handy to maintain an even shape for the length of the piece as I run it through the saw. Usually the log is oddly shaped on the outside edges and I bandsaw the log to the final shape. So I try to make the rough log a little bigger than it will eventually be. I didn't do the endless martini rosette until I had done a few of the other rosettes. It was definitely harder to get everything to fit nicely around the ring. Dark wood is your friend. Hope this helps. |

Yes, that helps a lot. Thank you. Now I've got some experimenting to do. I'm kind of hoping Alan Carruth will chime in and show some of his jigs that you mentioned. I looked at your website and it looks like many of your rosettes use this technique. Very nice work. |
