Re: toolpath strategy for complex shape bookshelf

I'm not sure how I'd cut a project like that. Making it out of solid wood in slices, you are going to burn through A LOT of wood, probably more expense in wood than you'll be able to sell the completed project for. I estimate 1000bf of rough oak, or approximately $4500 worth of oak in my neck of th...

Re: toolpath strategy for complex shape bookshelf

You could make it as a stacked lamination, however, the planning, construction and cleanup -sanding would be enormous. You would need to plan the joinery between the vertical and horizontal pieces so that the grain was going the appropriate direction for strength. You could not just glue up a wide ...

Re: toolpath strategy for complex shape bookshelf

No doubt you know this will be a challenging project to say the least. Your strategy to cut this project in slices will have a waste factor on the order of 75 percent (you will be essentially cutting out the cabinet from a solid block of wood). I hope you have a fireplace to at least get some heat ...

Re: toolpath strategy for complex shape bookshelf

Here's how I would approach it. I would cut it in layers of 35-50mm thick. Each "layer" would actually be made up of two thinner glued up layers, with the joints staggered. Cut the wood so that the grain follows the shape, so that there is minimal end grain. This will both look much better, but als...

Re: toolpath strategy for complex shape bookshelf

The piece dimensions are around: 450x2100x2600. Are these numbers correct? They seem much too big. 18" deep?? 7 ft x 8-1/2 ft?? Yes, 6,8 ft x 8,5 and 17,7 inch on the deepest part, because the thickness (deepness) is variable. It should be a bookcase. Do you think it's hard to build it so big? I kn...

Re: toolpath strategy for complex shape bookshelf

What is the size of the bookcase you are trying to make? The picture of the completed piece seems small although there is nothing to show scale. I am pretty sure that the pictured piece is not veneered. I have done a lot of veneering and veneering of curved panels over the decades and I don’t think...

Re: toolpath strategy for complex shape bookshelf

Alex, Here are links to some of Russell's work: Chairs Round Chair, copy of Hans Wegner's classic chair I know about Russell's work and I love it! I never questioned his expertise. In fact I appreciate his and everyone's feedback. I'm just trying to learn how possible it is to make this out of soli...

Re: toolpath strategy for complex shape bookshelf

Just an observation, but if you want the bookshelf to look anything like that picture, then you need to use veneers and not make it out of solid oak. That bookcase is most likely made from MDF and then has a veneer laminated to it. Carving that out of solid oak in slices will give you a very differ...

Re: toolpath strategy for complex shape bookshelf

Good info. Thanks! I guess i'll use a roughing bit then, since i want to reduce my machining time as much as possible. The machine has 24000 rpm and weighs about 1.6 tonnes, so i guess i could harness the capability of a roghing mill :)

Re: toolpath strategy for complex shape bookshelf

I was thinking about using a roughing mill for the 3D roughing tool path. Can i use the end mill for roughing? I was actually wondering why can't i just do the 3d roughing with an end mill. Any idea 's the difference between using an end mill or a roughing mill for 3D roughing? I actually didn't thi...

I have uploaded some 3D images with the piece. The piece dimensions are around: 450x2100x2600. The mac...
