Let’s make one of the wheels!
It’s the wheel at the bottom of the spindle. 

I made the rims on my CNC 

Glueing the parts together 

Adding all the tooth into the wheel

Making the “kruisarmen” (cross beams)   

Note this is not a half lap joint! To prevent the wedges holding the wheel from driving the joints apart there’s a lip preventing this.

To lubricate the thoots pure beeswax is used

All mounted
