So I found an old picture of 20 years ago with my son and scanned it. I've build this crane for him from technic sets from my youth (first Technic set model car, tractor, fork lifter etc.).
Remember back then there was no bricklink, what you had at home from sets, that was it. I remember experimenting with normal rubber bands for suspension before LEGO had them.

I had build him a fully functional extendable boom, side supports on the truck, a truck cabine at the front (not so visible) with HoG steering (visible)

Actually surprising that I came out of my dark ages only 5 years ago for RoscoPC F1 cars, GBCs and Modulars.
Hope you like it, show me your pictures if you are an oldtimer like me.

By the way, he never liked Technic much despite my efforts and was more into castle (which I don't like) :)

I can do an old picture (well video) but not of a MOC. Try LEGOLAND in 1969:

I had just turned six. This was shot by my dad on a cine camera (hence no sound) and I had it transferred to a DVD a few years back.

Not quite so long ago, as my son is only 8... but here's something I made for him, when he was a toddler:

Wind-up thingo

 

and a powerfunctions controlled windmill

Of course, he now raids all my technic lego, and builds his own contraptions!

 

Here's one of my favourite Christmas Mornings.. probably around 1983 (my sons current age!), building something from 8090 Universal set

 

Wow nice pics and video, I have to take some pics now and show them in 10 or 20 years.

This is the main leftover of what I built when I was a kid. It must be over 35 years old. It has rear wheel drive, independent suspension (reinforced with torsion bars), Ackermann steering and a fake V4 engine.

My first builds after my dark age are about 4 years old and my kids still play with them (the red model is a heavily modded version of 8845). Both models have torsion bar suspension and Ackermann steering.

Currently my son is playing with the same Duplo train!

Nice builds and nice to see! The Duplo train was great and I still have it in a box on the attic for the next generation :)
