Nearly there Achim.  When it's finished it is going to be a wonderful model.  Really love what you did to the base with the tiles.  I might do something similar to my build.

Hi everybody, the last weekend was a good one. In Bavaria we have had an extra bank holiday today. I have made this weekend the first real parts with my CNC toy for a current project. It was the last batch of 8 eccentric rings for the 16 valve engine. My CAM is the VCarvePro and I like it. I have made 6 different tool paths for this job.
#1 machining lower side of the part in two steps 3,1mm deep each, with an oversize of 0,2mm to the final outline.
#2 synchronous milling of the last 0,2mm in one go over all
#3 milling the 0,5 mm section ( circle)
#4 machining the upper side, outline in two steps like above, with 0,2mm oversize
#5 synchronous milling of the last 0,2mm in one go over all
#1 to #5 was running in one go
#6 Finally I had to turn the parts around and milling the 0,5 mm section (circle) on the other side.

Achim, the pictures on your last two posts came through fine!

Another option is to upload the photos to some other service (Flickr, Photobucket etc) and insert links to them in your posts.

Achim,
  I was getting exactly the same 'Forbidden' error when posting, and arnoldb was able to help me out. Neither Arnold or I can explain it, but when I changed my profile to default to the WYSIWYG editor, the problem was solved! It's worth a try.

Dear Lady and Gents,
first of all thanks for visiting my thread.
I have been able to finalize the main valve for the engine. Basic is a block valve from stock for 6 mm tubes.
I have made a disc from brass and fixed this disc by soft soldering to the cap nut of the valve spindle.
A spacer under the floor has given the right distance to clamp the block valve at the floor.
Then an extension was made for the spindle.
Now the hand wheel is in a comfortable position.
So I can start with the real plumbing now.

You'll be running soon, Achim! Did you make that handwheel, or buy it?

Hi Simon, the hand wheel was part of the block valve I have bought.
May be somebody in Europe has interest about the source.

Hi Achim: Your machining is A 1 Terrific. That is a very nice engine you are building. I joined this site just a short time ago and I put some time aside from my project to see what my new friends are doing. I wish you the best of luck and I will keep watching.                Jack B
