Now that I have the base area for the ripple, I need to extrude the vise’s outside shape (the purple line) like I did in the last post. Note how that vertical center line goes right through the new ripple surface to the center point of my original 2D line. Here’s the view of the trim result from the side.Īnd, a better view yet when I only show the outlines. Next, I trim off all the parts of the wave surface that I don’t need. See, I told you those red alignment lines I drew would come in handy. The next step is to align my large ripple surface with the vise stock lines I drew in the first post of this series.
In this case, I’m starting to revolve around the vertical red line on the left. Most 3D CAD programs will have similar tools. Revolve is just like “extrusion” that I mentioned earlier except you rotate around a point. Next, I used a Rhino3D tool called “revolve”. Starting from the vertical line I added for alignment on the left, I used my curve tool to draw a squiggle toward the right. It’s the frequency of the wave and it’s just a single line. If you took a verticle slice of a ripple, you’d end up with a squiggly line. It’s easier to show you in a series of screen captures. Let’s start with the 3D ripple shape of the vise on the prototype workbench. Now, for the fun part: creating 3D textures and patterns that are applied to the front face of the vise. Rather than a square and blocky shape for the vise, I used 3D drawing tools in Rhino3D to give it a gently curved shape.

In earlier posts, I used CAD software to create the 2D design for the BARN Workbench vise chop and the I built a pin registration board for two-sided machining on my CNC.
