Thank you for the video, understand the process better now.

The setup in this video is much better than mine.

I am going to ditch the chuck holding the cutter and use a draw collet. Then I can shorten the stylus to make the system more rigid

I still have access to the Deckel , just it’s a two hour drive to get to my friends place to use it and I then have to set everything up, turns into a very long day.

I don't have a 10mm draw collet for my mill, I only have imperial sizes. I had to make up a sleeve so that I could use the 1/2" collet to mount the 10mm end mill.

By using the collet the length of the stylus was reduced by 80mm, which greatly improved the rigidity of the setup. I also changed the clamping setup to give me more space to work.

First I machined down the centre line and stepped down and locked the quill at the depth and then machined all the way to the left of the picture. You can clearly see the steps in the photo below.

Remaining on the centre line, I then free handed the quill with a light pressure on the feed handle. Several passes the get it to blend.

Then I started indexing the table in 0.5mm increments and manually controlling the quill feed with light pressure to follow the contour of the pattern. I took 2 cuts per increment. I used the power feed on the table for all cuts throughout the whole process.

This rib is not going to be visible, it is going to mount the forend stock and add some much needed weight. It is going to be screwed and souldered to the barrel, to make it stand up to the recoil. I will clean up the outer surface by using the tool & cutter grinder as a surface grinder.
