Nothing special here but I did like the outcome.  This was cut in black walnut.  The rope border is not part of the ranger badge but I thought that it dressed it up a little.  The rope border came from Vector Art 3d some of the vectors came from the Vector Dr, the rest I did in Aspire 3.5.  When I do it again I am certain that I will change the wreath/componants/or what ever they are called on the sides to v-carve.texas rangers.jpg

Nice job Rick!
How many hours to machine? What was the cutter size?

6 hours for the finishing tool path.  The reason it took so long was I used  1/16 inch bit, the 1/8 would not totally fit down inside of the wreaths or whatever those components are called.  FYI the plaque is 16 inches round and dome shape which shows up in the picture.  But in the future by deleting the wreath type components on the edge and go with v-carve I should be able to have a faster time. 

Thanks for asking.

Not sure if this is what you mean or not.  I almost could have gotten away with a 1/8 inch ball nose but noticed a better preview with a 1/16, but I did bump up the step over just a little.  FYI this plaque is 17 inches round and the finishing tool path took between 7 and 8 hours to do.

Now the truth is I could always use a little expert guidance, so if you see something in that tool path that is not correct, let me know.

Also I am using a shopbot buddy with a PC router.

Thanks Rick! I find the computer end just as awesome as the finished piece. I hope I'm not the only geek on here!

Here is one more preview shot, which will give you an idea how deep the horns are.

Rick,

Looks great! I was wondering about the bit you used with a 5.4 degree side. Who makes it and what kind of speeds are you running in walnut?

Thanks,

Mike

This bit seems a little beefier than most 1/16.  I did the whole thing in 1/16 with a higher than norm step over.  Two or three different projects, I tried to change ball nose bits mid stream and I always ended up with ridge.  I always z-zero from almost the same location and even have an "X" marked on my zero plate.  There for a second I thought perhaps I entered my tool wrong looking at your question, but it appears to be spot on.

I would have finished this plaque today, but about the time I took the paint brush out of the mineral spirits the door bell rang, so back at work tomorrow.

Speeds.  I have gone as fast as 3.0 inch per second,.  but I have tapered that off a little and plunge rate is 2.5 to 2.75 inch per second.

Here is a question for you experts.  I am doing ok with the finishing but what is the proper tool to use for roughing, including speeds and step over.

Turns out I actually have that bit so your speed info will be very handy! I rarely do anything with small enough detail to use 1/16" but have been looking at some touristy stuff lately to build up business. Lots of gift shops in the Newberry area...

Thanks!

Mike

It seems that I use it a lot.  I do retirement plaques with bold raised letters and to clean out the inside of the letters better I opted for the 1/16.  Precise even has a 1/32.  I am scared that I would break it just by looking at it.
