Well, It’s been a long time since I posted a project on this site – but I’m still alive and still woodworking! I have made many small projects and gifts over the past two years, but never got around to posting them. This is my latest large project: A tri-axel Kenworth T800 pulling a 48 wheel Cozad steerable lowboy trailer. I have wanted to build a truck like this for years and was very excited when I decided I was going to build one. I have built around 4 trucks in the past; each one out-doing its predecessor in terms of creativity and level of detail. It’s kind of an unwritten rule of mine that each model I build must be better than the last – however the Bell 429 is still my favourite project (but this is very close). What is different from my last models is that I designed this truck using Auto CAD instead of hand-drafting, which proved to be much more efficient.

As on my previous models, this truck is made entirely out of wood, and does not contain any paint or wood-stain with the exception of the following components: – The wheels were painted black (but are still wood, not rubber). – The caution lights on the truck were coloured orange with pencil crayon on the lathe. – Sharpie was used for the “OVERSIZE LOAD” sign on the trailer. – The company logo on the truck door and trailer is coloured paper. – The door hinges are brass (see below).

The primary woods used on the model are walnut and maple, and other woods include: red oak, yellow heart, blood wood, padauk, ebony, cherry, and cedar burl. It contains thousands of pieces, many of which are not visible in the pictures because they are very small and are sanded to appear as a single piece of wood. The total length of this rig is 2.4 meters. Here are a bunch of pictures and a few little descriptions.

(Above) The Cat engine is made up of about 80 pieces. The majority of the engine is yellow heart, and all the black is ebony. Even the belts are ebony. I could not get the belts to bend around the wheels, so the curved components are actually made up of about 5 tiny pieces that are sanded to appear curved.

(Above) A construction picture of the front truck frame before the engine was added.

(Above) The hinges are made of brass sheeting that was bent, cut, and drilled to get them to the right shape. There comes a point where wood just isn’t strong enough to create such small parts – And these hinges are that exact point.

(Above) The textured decking was made on my table saw and is used to add a little more texture to the model in various spots. It looks cool and is pretty easy to make!

(Above) The trailer deck has the same positive camber that a real empty trailer has (is becomes flat when it is loaded with heavy equipment).

Thanks everyone for taking a look, and feel free to ask any questions you may have!

That is one incredible work of art. I have been making wooden models for a few years but you are light years ahead of me.
Just brilliant

That’s bad to the bone. Really like the low angle shots.

This is absolutely the best model truck I have seen on this or any site.

The engine and drive train are fantastic.

Thanks for posting it here

I checked out the helicopter you made and another amazing build.

The detail is phenomenal. I caught the positive camber in your first picture of it. That is really impressive. Could you post a picture or two of the detail on the front axle. I want to make a more realistic truck to put under a concrete pump that I made. I have some ideas on how to make the front axles steerable. I am always looking for more or better ideas.
Congratulation on the daily top 3. I hope we see it in the editors choice also.
