Mike-

The gear covers are works of art.  Well done.

Woa, fantastic result - again ....  :praise2:

Are you doing two engines (I forget) or are the other internal side 'just the pretrial' from the CNC Spindle debate ?

Thank you all for your encouraging comments. They make all the effort worthwhile.   :ThumbsUp: :ThumbsUp:

Yes,  Per, quite correct. I am building two identical engines. One to wash and one to wear, so to speak. A lot of work goes into preparing the CNC toolpaths, so the extra cost in materials and machine time justifies the programming time. Actually, they will not be identical when finished, One will be fully assembled and complete, ready to run, and the other will be another exploded display to show all the details, inside and out,  of the advanced engineering that went into the pre-war Silver Arrows Grand Prix cars.

I was just thinking today what a shame it will be when all that great stuff gets closed up inside the finished engine. Now I see your master plan, and I think it's brilliant! :cheers: :cheers:

I remember seeing George Lhhurs fantastically small engine models some years ago.  The running engines were fantastic, but he placed exploded versions of the engines on a card near by.  It gave you a real appreciation of the talent involved. 

Your model deserves the same treatment because, as impressive as the finished model will be, seeing all the internal work that went into it will just increase the ‘wow’ factor. :ThumbsUp:

Mike also did a very impressive 'Dual Engine - one runner and one Exploded' with his Jupiter build - where the 'Exploded Engine' is mounted on acrylic carriers, so all parts are held in the correct positions relative to each other.

It will be great to se this build shown in the same kind af arrangement Mike  :ThumbsUp:

Hello Per,

I am hoping to make a similar exploded display using acrylic carriers for the second W165 engine. It will be a challenge, as it is not as compact as a radial engine

Oh!!,  I only have the one Bristol Jupiter but two Bristol Mercury engines. You can find the 'Bristol Mecury Revisited'  build log at https://www.modelenginemaker.com/index.php/topic,9272.0.html

Reply #33 shows the completed Bristol Mercury display

Cheers

Mike

That exploded display is is just so impressive and fascinating to look at. It inspires me to do something similar one day, but I'd have to go shopping for more patience (or attention span?). :cheers:

First I was so happy that I remembered the name of the engine  :whoohoo: - followed by - strange that I can't find the right section of the build in order to link to the display  :???:

SO thank you for setting the record straight Mike  :ThumbsUp:

.... note to self - why didn't you search Bristol instead  :facepalm:

You may (or may not) have noticed that things have been quiet on this build for a while. I had taken a short break from model engineering and now return with renewed energy.

The first thing I wanted to do was to complete the camshaft drive, gear case at the back of the engine. Most of the parts were made towards the end of last year, all that was needed was to sort out the surface finish and put it all together.

Here is the sequence showing how it all went together.


First start with a bare crankcase


Then add the front half of the gear case


Next, add the crankshaft and magneto drive gears


That is followed by the two cylinder blocks with their four overhead camshafts and camshaft gears


With all the input and output gears in place, it's time to add the three intermediate idler gears




With all those beautiful gears fitted and turning freely, it's time to start covering them up. First comes the rear cover


Followed by the two outer covers over the camshaft drive gears


With the gear case assembled, the two-stage supercharger can be put back on the front of the engine


Here you can see the dry sump located below the crankcase and the 3D printed (plastic) exhaust header



My daughter thought she should also get in on the act She said it was to give a sense of scale to the engine


Cheers

Mike

I had noticed, and was hoping it was just a simple pause to refresh. Your daughter is right, a live person does give a better sense of scale than anything else. But regardless of scale it is a fantastic piece of work and I'm glad you're back on it!

Ron
