Step 3 Create bucket base and buckets

I made the buckets by screwing the bucket templates to the base plate then screwing flat sheet metal to the templates to construct the buckets.
I made the base plates out of 18mm exterior board 330mm wide. 650mm accross. Draw centre lines on long and short axis. From the centre created by this intersection draw arcs from each end long axis. I used a pencil on a string to create the arc and cut along this arc with a jigsaw. If you use a full circle base make the circle of radius 325mm.
Four bucket base templates are required. I used semicircles but you could change this shape to increase the efficiency of the bucket. Read a few articles and you will get a few more ideas. I made them from an old 20mm pine shelf but chipboard would probably do in dry area or 18 exterior board if getting wet.
Fix the base templates to the base such that the flat sides are along the long centre line. I over lapped the the semicircles 80mm. I used three self tapping timber screws to hold each as well as contact adhesive glue. Next one I build I won't glue just use more screws as this will allow me to "play" with the bucket shape.
Cut a 50mm hole in the centre to allow the axle to come through.
