This toy can be made with a limited number of power tools.
Safety is always the first consideration when dealing with such small pieces of timber.
A 12 inch disc sander or linisher with sanding disk attachment is very useful for trimming up end grain and squaring off small pieces of wood.
If you are going to make your own wheels, a drill press is recommended.
You will also need a 16mm spade bit, a 6mm drill bit and a
modified to cut wheels instead of holes.
This toy can be made with bits of wood left over from other projects.
I made mine from a piece of left over pine 19mm thick by 140mm wide by 500mm long.
The wheels were also cut out of 19mm pine by 140mm wide.
For the six wheels, I used a piece less than 200mm in length,
and the extra length was useful in clamping the piece while using the circle cutter.
The blade of the grader was made with a piece of skirting board 200mm long.
For the axles, use 6mm dowel.
Step by Step Instructions

Step 1. The first step is to read through the instructions and study the plans and photos.
Step 2. Using a soft pencil and a ruler, mark out the component parts as shown in the drawing.
Cut out the parts using an electric jigsaw, a backsaw or a scroll saw.
Parts A to D are trimmed back to their proper sizes. A twelve inch disc sander is useful for trimming small pieces.
Glue the pieces that make up parts E and F and put to one side to set.
Clamp parts B together and drill the holes for the axles. At this stage, the holes are drilled for a snug fit. Do this in order to make sure things stay lined up when the parts are glued and clamped together.
Dry clamp parts A and B together, keeping the two parts B aligned with the axle dowels.
Mark the pieces so that it will be re-assembled in the correct order.
It is shown in red in the photo only to highlight the idea, so don't actually mark it in red.
Apply the glue, clamp it and put to one side.
It is important that the axle dowels are left in place until the glue sets to minimise creep under clamping pressure.
Once the glue has set, re-drill the holes to allow the axles to spin freely.
The blade of the grader, part C, is made from a piece of skirting board cut to a width of 30mm.
It may also be made from a piece of timber that is 9mm thick, just chamfer one edge to the profile shown in the drawing.
Cut and trim part D to size, and drill the axle hole using a drill press or drill guide.
Use the 6.5mm drill bit to allow the axle to spin freely.
Once the glue has set for part E, mark out the windows as shown in the plan.
Drill a 4mm hole in each of the corners as shown in the photo.
This should be large enough to fit your jigsaw blade.
Note the two 6mm holes in the face for a pair of alignment dowels.
Cut in half along the line shown red in the photo.
Cut out the front window using a jigsaw, a coping saw or a scrollsaw.
Using a chisel, chop out the waste to form the windows.
Clean up using a chisel, files and sandpaper.
The two halves are glued back together again using the alignment dowels.
Using a scroll saw would leave a better finish and save a bit of time.
Glue all the parts together, apply the wood screw to the front wheel assembly, allowing it to swivel.
Round off the sharp edges and you are ready to put the grader to some serious earth moving work.
