Hello again!
Today I wanted to show you, how I did the fifth wheel. First I painted the mount in the frame colour, then I painted the areas where the paint would wear off in Humbrol 53 - gun metal:
Then I applied black artist oil to simulate the grease. To spraed it, I used a purpose-built tool (pictured):
Next I went to do the fifth wheel itself. On the bottom of it I built parts of the locking mechanism and its release:
I painted the bottom side gloss black (Humbrol 21), dry brushed with dark gray (Humbrol 32):
For the top of the fifth wheel again I used Humbrol gun-metal, sparsely brushed over a coat of gloss black:
Finally I applied the "grease" - again, a black artist oil. To spread it I took a piece of sheet plastic with a pin to work as a trailer's king pin, and made several circular movements with it to spread the "grease":
The oil paint took some five days to dry, then I put everything together. The air line to the actuator is made out of soldering wire painted with Gunze paint. the whole subassembly now looks like this:

Hope you like it, thanks for reading and have a nice day
