Since the base of the tenons also have the 15deg. engraving bit is probably too fragile unless the material is very soft the 30deg. I present the math on the CNC Zone thread, which is pretty simple trig, which really is pretty simple ratios. Theoretically you could use a wider angle, but then the tails on one side would look smaller. Thanks, I thought it was an idea with merit, though it hasn't really taken off. Is it as easy as using half of the bit angle for the pin and socket angle? It looks like you used a 15* angle on the pins and tails. I was wondering if there is a formula for using different angle bits. Mrmfwilson wrote:I know this is an old thread but I have been looking for something like this for a while. Rather than retype the entire text, I'll provide the link to the CNCZone discussion: And as long as you use the bits mentioned and keep the pin angles half the angle of the v-bit, you should be able to make the pins very skinny. However, for the occasional, or one-off project like a jewelry box or blanket chest this just might be the way to add detail to your project without having to buy an expensive dovetail jig. Though the drawer sides could be nested, I do not present this a a way to mass-produce drawer sides. The tails, however, would need to be trimmed either on a table saw at a 15 degree bevel, or on the CNC using a 150 degree v-bit. I hog all the waste first, then use a 30 degree v-bit to cut the pins and tails. Using VCarve Pro's v-carve toolpaths, I've developed a way to cut THROUGH DOVETAILS, on the flat, with no need to slot the table. While there are cabinet programs that havev dovetail joint "modules", the resulting joint looks more like a Leigh Isolock more than anything. This is probably my first post here, and I hope to learn as much as contribute.Īnyway, for those interested, there was a discussion over at the CNCZone about different methods of making drawer joints on the flat. I don't think I've tapped into all it's capabilities yet, but hope I have a chance to discover its may features in the future. Hey all! I've owned VCarve Pro for almost a year now, and have enjoyed using it very much.
