I've look at the 3 or 4 you've Posted in the last little while. I was looking for an explanation of "Segmentation". Please excuse my Ignorance but I'm not familiar with that Process.
I guess I could Google it but I'd rather hear your explanation.
You mentioned in one of them that it's a lot easier and faster than Intarsia. Could you give an explanation of that process please. Also the types of wood you have used.
Segmentation is very easy to do and all you need is a scrollsaw, since you need the small blades. This entire project is done with a single piece of wood, compared to Instarsia that uses multiple types of wood hat yo have to fit together. What I like about segmentation is the 3D effect by different stains and raising or lowering each piece. Great book that I use is….Animal Portraits in Wood: Crafting 16 Artistic Mosaics with Your Scroll Saw. There are others too. Take glue the pattern on a piece of wood. I have used pine, popular or 3/4" birch plywood. You want something light in color. Cut the entire pattern out. Group items to be stained and stain. Dry, Refit entire pieces togther. Flip over and use a hot glue gun to start offset pieces based on pattern. This way all glue joints are hidden….Good luck.
