Here is how I made a clockwork desk or junkyard scrape table. What ever it looks like to you. It wasn't perfect planning on my end but turned out alright if I had to do it differently I'd definitely start with thicker glass. Build something smaller than a few/table to start and have a finished product in my mind instead of drinking through it.
let me know if you have any questions.

Supplies

Tools:
I used welder, cut wheels, chop saw.
Materials:
Anything you can get your hands on. Fly wheels crank, cam, transmission gears what ever fits your artistic eye.
I used 1x1 in square tubing for structure.

Glass:
Preferably something thick

Step 1: Arrangements

Begin arranging different gears and parts withing your structure to create what kind of look your going for. Make sure you are working on a flat surface and when you are happy with how it looks begin taking everything in place .

Step 2: Legs and Wheels

Deciding to put wheels on the legs was a great choice for me, because all that metal adds up. Wheels made it more Mobile and easier to place where I wanted it.

I mounted the wheels by drilling a hole the

Step 3: Patina or Paint

I decided to paint mine with a bronze pearl that I had laying around. I almost left it how it was but changed my mind last minute.
Another thought I had was all white then outline the glass with LED lights to create an effect.

Step 4: Finishing Up

I ended up putting double sticky tape between the glass and metal just so I didn't have metal on top of metal. I used a think piece of glass the first time and ended upgrading to something thicker because I broke it.

If you want this one let me know I'll sell it cheap. i have been looking for a reason to build a different one.
