Sure someone can advise any obvious mistakes, still learning.

Great on the mechanical design George.
If you are shooting for photo-realistic, may I give some observations, constructive criticism?
1. Balancing on the end of the crank gives an unnatural appearance, you may want to think of position in a more natural angle
2. the radial bearing is a bit too white, some dark blue/grey to the chrome material metal will help
3. camshafts are typically cast metal with only the bearing surfaces get machines to a smooth surface.
4. ball bearings are usually of a high Rockwell hardness and the chase is usually softer which would be a more grayish blue
5. the piston rod looks great, but appears to be a cast bronze material?
Great job on the CAD model, very well proportioned

Thanks John as always open to help.
The crank is that way up as I was having some trouble rotating it, and tried to rush ahead with the render.
The reason for the dark chrome is to try and show the ground polished outer faces?
The bearings I simply struggled with.
The Rod is forged and copper plated for the hardening process on the exposed faces, this is how standard rods look.
Thanks for the suggestions.
George.
for the radial bearing, try "Chrome" but change the RGB to 190, 190, 202
and bring the roughness to about 0.020
leave the balls as straight chrome.
did that help any?
Thanks I will give that a try.
John
Working on the bearing. Thanks for the advise.
Here is a photo of a real crank and rod, shows copper bronze and machined ground face.

Any better ?

Thanks Geo.
Wow! that little change made a big difference yes?
looks great!
john
Yep. Thanks for your help, get there one day !
Geo.
Wow! Good job on that last image. Colors are spot on. Now, try the attached texture to the ID and OD, using cylindrical projection. Play with scale and intensity as well. Enjoy!

Bill.
Thanks very much for your help, I will give it a try tomorrow.
Colours are down to John, the rest is luck !!!
Geo.
Bill,
Thanks for the texture, It was so intriguing I had to give it a shot myself

I used chrome and changed the color to 190,190,202, increased the roughness to 0.040.
using bill's texture I brought the intensity down a hair and jacked the scale up a bit
My effort Bill.

Thanks Geo.
And ???

Geo.
very nice George, much more realistic.
Thanks both been quite a journey !
Beginning to understand what I should be aiming for.
Bill, just down loaded your knurl texture will have to have a play with that.
George. ;D
Bill.
Just understood what you wanted me to do. have remodeled bearing so retained colour and ground texture only on inner and outer surface.

Any better ?
George.
You have come along way with your image. Keep up the great work !
Once you figure out the textures I would go back and think about how you can dirty them up a tad. When I say a tad I really mean just a tiny bit.
Tim
Geo,
the new bearing looks great, but the balls which are typically very high Rockwell hardness could use a bit less roughness, more high-reflective chrome.
the angle of the texture is perfect! it runs longitudinal to the axis which gives the impression of a stamped race as a true bearing would be.
it gives the true impression of a stress in the metal as a pressed fit would have - great job!
I have polished my balls !

Thanks for comments Feher.not sure how to dirty up collours but will have a play.
Geo.
LOL - yes they are! ;D
Geo,
now that looks GREAT ! Putting that warm light really made those bearing come to life. When I say dirty I'm thinking a thin coat of oil on the bearings.
At any case NICE work on your balls buddy ;D
Tim
Thanks for help Tim.
Geo
Hi George,
You're coming along good. Don't forget to cage those balls. ;)
Couple of things to try if you get bored - it's little details that take it over the top. Try adding the bearing cage and give it a hint of greenish gold color to give it a little contrast. Another thing to add would be the bearing part number and make to the outer ring.

Not too sure.
Geo.
Looking really good. Only comment I have is the "hot spot" on the surface where the lighting hits. Try rotating the environment and also play with the height.
Many tanks Thomas.
I have learnt such a lot from the guys on this forum, sometimes you just can't see the full picture yourself.
at least not when your as clueless as me!
