New 3d Model
Had this model made at PeopleforHire.com from a Jpeg. Still needs work. The finish was rough and requires a lot of sanding. Broke a bit during the process. But we are gettin there.

Looks good so far. Change the stepover on your tool to get a better finish. I use between 8-10% stepover on my tool bits. See example. When I do 3D work I never have to sand.

Re: New 3d Model
Thanks for the tip. The machine times are crazy any way to speed that up?

It's either smooth finish with long carving time or you do a lot of sanding. I like no sanding, less labor.

You should set your stepover for your ball end mill by the size of the endmill to get both the finish you want and the time efficiency. Use the chart. I am very happy with a .0003 high stepover cusp for finish. With a 1/8 ball that equals 10% stepover. With a 1/16" ball its a 14% stepover.
Your times can also be affected by your feed and plunge rates. You are taking very small amounts off with low stepovers so you can work to higher speeds. 70 ipm for feed and 25 ipm for plunge are common for me in hardwoods. Your machine and router might be able to handle more.

Re: New 3d Model
Thanks for the advice. I figured it was one or the other. But I'll play around with the feed rate a bit.
