I have a friend who is starting a local chapter of the Columbian Squires. The Squires are an international fraternity of Catholic young men, Founded by the Knights of Columbus. My friend wanted to know if I could make a plaque of the squire’s logo, on my CNC router. I told him that I would give it a try.
I find the Carvewright software to be rather basic, so I drew the logo up in AutoCAD, then exported it to an STL file. I imported the STL file into the Carvewright software, then created the image you see above. I sized it to be as large as the carver would allow, about 14.5″ tall. The next step was to create a panel to carve it into.
I pulled a couple of maple boards from my stock pile, and cut them to about 24″ long. The carver likes an additional 3″ minimum on each side of the carve, so I needed a minimum of 21″, I made my pieces a little longer so I could plane them down and not have to worry about snipe ruining any of the boards.
I ripped them down to the desired widths, then ran them through the planer, to clean them up.
I applied wood glue to the edges and started clamping them up. It appeared that the center board had a slight bend to it, so I clamped the right side first and worked my way left counter-bending the center board until it was flush, then clamping it in place.
I also clamped the offending board on the end to prevent it from shifting as I clamped the sides. After about an hour, I pulled the clamps and scraped off any glue squeeze-out with my 2″ wide chisel.
I trimmed the edges square on my sliding miter saw, then loaded the board into the Carvewright and started the carve.
3-1/2 hours later the program finished, and I removed my board.
All the little fuzzies that were left behind were sanded down with my buff sander, mounted to my drill.
With everything cleaned up, I cut the plaque square on the table saw.
I am not sure what finish is desired so I am going to turn the plaque over as is. I will let my friend paint, stain, or finish however he sees fit. I will post an update if he sends me a picture of the finished product.
If anyone would like a copy of the Carvewright file or the 3D STL file, just shoot me an email at firstname.lastname@example.org
