Wooden Monster Truck.

This monster truck is another great woodworking toy from Les Neufeld.

Full building instructions are given is Les' book, but there area couple of areas worth mentioning where things were done differently to the instructions given.


Terrific Monster Truck.



First of all there are a couple of dimensional errors in the instructions.

On page 5 the bottom measurement between front of frame and front axle housing is shown as 9/16". It should be 1 9/16".

On page 10 the bottom measurement of the frame is shown as 61/4" but it should read 81/4".









This model required much more sanding and shaping that the other trucks particularly on the cab.

This was made easier by temporarily attaching the cab to a baton and wood and clamping this in the vice so that strips of sand paper could be used to round things off.


Sanding the cab shape









The open back of the truck was supposed to be a U shape cut from a block of wood, but my small band saw struggled to cut this depth.

Instead a simple box was made up from chunks of wood glued together.

The wood parts were cut from one piece of timber to keep the colours constant and then sanded all over before gluing.

Pick up bed of truck









The wheels required significant work.

First some blanks were cut out on the band saw and drilled with a 10mm hole in the centre.

Then they were trimmed up on the sanding disk using a piece of wood with a 10mm rod inserted in it, as a centre guide.

Ready to sand up a wheel blank









The milling machine and the rotary table were used to cut the tread pattern.

A 6mm cutter was used and the machine set to a high speed. Then each wheel blank was mounted on an arbor and indexed to cut the tread.

Four blanks were done with the rotary table rotated one way 10 degrees and then the other four were cut with it turned to -10 degrees.

Cutting the tyre tread









Next - half the wheel blanks (two of each tread direction) were bored out on the lathe. These would be the outer tyre parts.

Then the wheel halves were glued together aligning the outer surfaces as best as possible.

To finally true up the wheels they were returned to the sanding disc jig to smooth things over.

Wheel truing









The same jig was used with the table dropped by 45 degrees to add a chamfer on the wheel edges.

Wheel chamfering









Some wheel axles were turned up from hardwood on the lathe.

These were measured against width of the tyre to ensure the correct length.
