Hello Everyone,
This is not my first project but it is the first one worth showing off. These were cut from 6" x6"x3/4 stock and are about 5" across. One is birds-eye maple and the other cherry. Thickness is 1/16" - a tribute to the shopbot accuracy and repeatability!

Those are beautiful! Were they commissioned, gifts or...? About how long per dish?

Great work and design. Was this done with Artcam?

Terry,

Correct me if I'm wrong, but did you turn these first, then cut out the heart shape and the perforated design with the Bot? Very clever, and nicely executed.

Thanks everyone for the encouragement!

These were completely made on the shopbot.
The general layout and braid work was done with partwizard. The dish shapes were cut using a 1/2" round nose spiral upcut bit. I have a programming background so the part files were created using a program I wrote that generates a circular spiral cutting pattern while continuously changing the cutting depth. To get a fine finish the spiral pitch was 0.03" per revolution. A bit of finish sanding was still needed but the spiral really makes a nice surface. Cutting time for the top was ~12 min and the bottom ~15 min. The cutout and braid work was done with a 1/16" end mill and takes about 3 min. and is cut into the top of the dish before it is turned over and the bottom is shaped.

Thanks again for the comments,

Terry

Well, I don't know about everyone else, but I'm impressed. How difficult would it be to create a part file with variables that would allow one to do dishes of different diameters, depths, etc.? There might be folks willing to pay for that.

Terrific work.

Matt,
The idea is interesting, but like most programs the last 10% of the effort takes 90% of the time. The process is definitely not user friendly at this time.

Evan,
No, they are not commissioned work and I'm sure that some will be gifts. Working on the marketing end now - local jewelry stores might be interested.
