Bruce Macbeth Engine, European Version

I really like the colors added to the engine.

Mike, George thanks for the encouraging comments. Good to know that you both are still following along. I appreciate it very much.


Headword color.


I took the set up cylinder head #0 for a first powder coating trial.
First idea was to make some masking by metal sheet, but after an investigation I realized that it could be done by some tape easily also.
The set up cylinder #0 and the set up cam shaft braked #0 has been used as a cutting pattern.
Set up cylinder was not bad, cylinder #1 has got to much powder by my fault, but it is at the bottom side, so it will be hidden.
The pictures are a bit mixed of cylinder #0 and #1.

... and two more pictures.
Cylinder #1 fitted on trial basis at the engine.

 That's going to be a fantastic looking engine!

 Great work all the way around Achim!

This is a great looking engine, Achim!  Love the powder coat and the anodizing  

Just curious, why'd you choose to anodize some parts and powder coat others?

Hi John, thanks for watching and giving friendly comments.

Hi Kim, because deep inside me is a lazy guy.
The actual goal  was to get them black only.
These camshaft bearing brackets does have in my understanding lots of sensitive functional surfaces. So the black anodizing was the easiest way to get them black and keep all sensitive surfaces untouched.
The irregular surface of the power coating does match better to the bigger parts like the cylinder heads and so on, in my eyes.

Hi Achim
I love all the detail that you are putting into the engine and display, it sure is looking nice!

Hi everybody,
the rockers are back from anodizing also.
Time to do a research if my metric conversion of the valve train is really functional too.
The lobes are not made until now, so I made a dummy, the brass part, with the base circle dimension one side and the bump circle the other side.
And oops, the shortest adjustment of the vale with valve cap/spring retainer is to long.
The valve is already opened, only a little movement but a bit to much, no valve clearance adjustment possible in that case.
A valve fully open does not show any problems.
A decision was made to rework the valve cap/spring retainer. First I have modified a tap, by grinding of the tip, to get some tenth of a millimeter more length of the thread.
But that did not help to fix it. So I measured the thickness of the valve caps and saw it was possible to shorten them a bit without any risk.
Now there was a gap against the basic circle dummies visible for the later necessary valve clearance adjustment.
Don´t be irritated by the surface of the cylinder head in the picture, that is cylinder head #0, my set up part.

... I thought may be it is worth to show some picture of the assembly, disassembly and new assembly mess also.
It keeps me busy whole time.

The last detail missing, before the attack of the cams, the shortening of the roller pins.
And the hopefully final assembly of the pins with Loctite into the rockers.

[Admiral_dk]

Another batch of nice new shiny parts 

Great that you caught the missing clearance before commiting to making the rest of the camlobes

[Roger B]

Looking good     

Are the pins Loctited into the rollers or the rockers?

Hi Roger, thanks.


The pins are Loctited on one side into the rockers.
