Hello Peter, it´s fine glass.

The first of 10 presenting the finished Cylinderhead pearl blasted with valves. Valves are not fine grinded. I am happy

Now the BF20CNC is working at the body fins. I bought a carbide 20x1mm sawmill blade ind made a tool for clamping tool for it. I let it running too times because of the 3,8mm deep cut. I used a axis shift by x-1mm If you watch the video reduce the volume because the air spray cooling is that...

Thats great, it is also my intension to keep the brain in a better shape.:D I almost can do my job without thinking thats why I need a new challenge with 56.;) You have my respect.:)

During the holy day´s I had some time to finish the top fin cutting of the 10 cylinder heads. I finished the inlet end exhaust side openings and then I need to wait for a saw mill tool 20x1 mm for the radial fins ending with a 10mm radius. Thats why I turned to the valves. I finished my first...

Hey Brian, impressive work. Looks great. I have never seen a radial with OHC. Is that your design? Keep on healthy.

The 4127.JPG shows only the procedure. I was wearing heat protection welder gloves and it was still warm;). I didnt make any pictueres while I made the 20 degree inner cone of the C-Head on the laith.

Three more pictures who will explain my work.

Fore the guys who are intrested in the metric drawings. Give me some time. I need to do something at the drawings, (measurement, change the german language to english) but I dont forget it.

Some progress at the cylinderheads. I follow the procedure given by JUNG who toleranced the valve cage 0.05mm bigger than the bore. I made dem 0.07 bigger and heat the cylinderhead. So the pressure was high but it works. In my opinion it is the better seal than chemical glue like locktite. Now I...

Hey Peter nice to hear from you.:) First I wanted to stay with the imperial gears, but it is so easy to get the same gear reduction (number of teeth) at the German supplier and I didnt get the imperial easy in germany. The out side teeth gear wheels I made myself. The inside is about 40€ each...
