Remember that wheelbarrow wheel I had laying around? Well, the tyre was flat, and I was too lazy to fix it. However, I found another good one in a junk pile in my old college, plus an old steel coat hanger support, which will come in handy for the handlebar.

We machined a steering support held by two pillow blocks (20 and 25mm in diameter, I had those laying around), bolted into a 1/4in steel plate.

The handlebar will be bolted on the thickest part (through a piece of pipe that fits over the coat hanger support) of this rotating axle, the lower, thinner part will be connected to the wheel. The wheelbarrow wheel is held by a hand-bent flat piece of steel, welded on another steel cylinder we machined to fit this lower part.

The steel plate is then welded onto a square tube and onto the frame itself.

An old table frame was also recovered in the process, along with a classroom chair, @Frédéric Druppel will mention it in the next log :)
