Need to cut round top ridge all the way around the face of a
I need to make a round top ridge around an octagon on the face of the wood. See Attached. Basically like a round over but on the face and 3/8" high and 1 1/4 wide.
This ridge needs to travel around the face of an octagon picture frame. Can anyone tell me how to do this? I can't find a router bit even close to what I need. I have vcarve 8 but not much else.
Please Help and Thanks for reading this post.

Re: Need to cut round top ridge all the way around the face
If this is what you want, it's just a two-rail sweep.
Re: Need to cut round top ridge all the way around the face
That is pretty close. This picture may show it better. I need what you have there but the ridge can't be right on the edge.
Is it possible to move it inward more. Not to mention I don't know how to do a 2 rail sweep.

It would still be a two rail sweep. Dale

You need to go thru the tutorials. Otherwise you will be very frustrated. 2-rail sweep is a basic tool you'll use often.

I don't believe the OP has Aspire...... only VCP8
Re: Need to cut round top ridge all the way around the face
That is correct. I do not have aspire.

Re: Need to cut round top ridge all the way around the face
You can do this with Paul Rowntree's fluteplus gadget. It will cut the ridge with multiple radial cuts.
http://paulrowntree.weebly.com/gadgets.html
Settings I used for the gadget:
Tool: .25 dia End Mill
Flute Mode:Use As-Is or Truncate Profile to match Rail length
Start Depth: 0
Flute Depth .15 (equals radius that I used for the bump)
Profile steps: 100
Note: using radial lines for the rails means that the cross section is not a perfect radius. You can draw lines perpendicular to the sides and run the gadget using them if you are a perfectionist.
The .crv file was too big to post with the toolpaths. So you will have to download the gadget (All 3 files, and read the instructions to see where they go.) and run it to see the toolpaths.

Here's a crv file with a toolpath for one quarter of the path.

Note that the start points on the rail and profiles will set the orientation of the contour.

Re: Need to cut round top ridge all the way around the face
One more note:
There needs to be enough room on the profile for the bit to reach all of it. That is, the flat parts of the profile have to be at least as wide as the diameter of the tool, and if you want the edge of the "bump" to be nearer the edge of the material than the bit diameter, the rails need to extend beyond the material. Also, best if the start points of the rails are at the outside edge (which is not true of my example).
