Mini Big Rigs – Crossing the line
Finally, a complete model replica of our subject matter – Ken Kirk’s Pilkington Automotive Glass Mercedes-Benz, circa 1992.

MAIDEN VOYAGE
We have made it to the end of our Ken Kirk/Pilkington Automotive Glass Mercedes-Benz build. With just paint and a few finishing touches to add to the trailer, we can load up, tarp up and hit the road.
Following our scratchbuilding efforts on the flat deck last month, the trailer is ready for paint and final assembly. Let’s start with the main trailer chassis assembly. The first step is to paint the largest area first – the underside, including chassis, suspension and axle sets. Completely mask off the top side of the deck, the headache rack and the coaming rails. Doing this will make life a lot easier when painting the top side, as you will retain the fresh, clean, white plastic surfaces and not have to paint over any overspray.
Following the balance of step 2 in the instructions, we now assemble the wheel sets. The first part of this process is to detail-paint the inner hubs and outer rims, matching the black and white combination on the tractor unit. Allow the paint to dry completely, and then fit the tyres. Remember to run the tyre tread over coarse sandpaper for a scuffed finish that replicates the natural wear and tear of the tread surface.
Once the underside is dry, remove the masking tape from the top side and begin assembly. The likes of our scratch-built underbelly tool locker can be fitted now, then move on to fitting the wheels as per the instruction sheet. The one critical piece of advice here is to be very careful with applying the glue to the ends of the axles. Using too much glue runs the risk of it making its way in between the axle and the wheel and permanently setting it in place. So, a steady hand and easy-doesit is the way forward here. I suggest only fitting the wheels to one side at a time, allowing them to dry thoroughly before flipping over and fitting out the opposite side. This will also help ensure you do not glue the wheels in place.
Finally, apply the detail paint to the likes of the headache rack, coaming rails and taillights. Modern acrylic hobby paints are much more forgiving, and you can add a drop or two of clean water to

thin the paint a fraction. This will assist the application and flow of the paint off the brush. A flat brown like Tamiya XF-68 ‘Nato Brown’ will provide a good result when painting the deck of the trailer to resemble plate steel. The best way to apply this is using a wide bristle brush – this way, you can flick the brush and achieve a slightly mottled finish to help replicate the uneven colour of rust-stained steel plate.
The final finishing touch is fitting a set of white mudflaps to the rear guards of the trailer. To do this, use the same technique we applied to the tractor unit, measuring and cutting 0.3mm Evergreen sheet plastic to the correct size. Using a file, round off the corners at the bottom edge of the mudflaps. Once happy with their shape and fit, glue them into place.
Now we have a completed trailer, it is time to back the mighty Mercedes-Benz under the kingpin, connecting the two as a completed unit for the first time. Stand back now and pat yourself on the back because there you have it – your first 1:24th scale model truck and trailer build completed and ready for display.
Next, grab your wallet and head back to the local hobby shop to select your next project. Keep on mini big riggin’!

1) The chassis and suspension are the detailed areas of the trailer to paint. By masking off the combing rails, headache rack and deck area, we can easily apply the black spray paint to the underside in an even and controlled manner. 2) Be sure to mask off the stub axles, ensuring the wheels go on with ease and assisting with glue adhesion for the retaining hubs (part 6a). 3) Painting the trailer wheels to match the tractor unit starts by applying the black paint to the centre hubs and then the white to the rims before fitting the tyres. 4) Once the wheels are assembled, fit them as per the instructions to the hubs. When applying the glue, use care to ensure that only the very end of the hub receives a modest amount, this way allowing the wheel to spin freely on the hub. 5) Robbing the parts bin to add the finishing touches… Our good mate Marty Crooks provided us with a pair of wheels to sit in the spare wheel rack, just as Ken had on the real truck – in an era before waiting two hours on the side of the road for the tyre man was typical. 6) The smaller areas can be painted now – the likes of coaming rails can be either sprayed or hand-painted. Today’s acrylics can be applied easily either way. 7) Using Tamiya ‘Nato Brown’ XF-68 with a wide bristle brush, we can apply the paint to the trailer deck to represent the mottled finish of a bare rust-stained steel deck. 8) When applying detail paint to the taillights, start with a white base coat to make the red and orange more vibrant. 9) The final finishing touch – making a set of mudflaps to hang from the rear guards of the trailer. As we did for the tractor unit, measure and cut to fit Evergreen 0.3mm sheet plastic, round the bottom corners with a file and glue into place. Job done!

LOADING THE SEMI
1) The big Mercedes-Benz delivered automotive glass to car-assembly factories throughout New Zealand. The loads were often a uniform shape because of the racking systems used to transport the glass windscreens safely. These loads were then covered with a tarpaulin to help protect the product. A simple way to form the basic rectangular shape seen in our guiding photos of the Mercedes-Benz at work is to cut an old shoe box down to size. 2) Once the box is cut down to the required shape and size, use masking tape to retain that shape securely. 3) Next, apply standard PVA glue liberally to the top and sides of the modified cardboard box. Once the box is covered in glue, start applying standard kitchen paper towels to the glued surfaces. Remember to fold your corners and ends as if you were sheeting a load with a full-size tarp. Have a bowl of water nearby so you can dab water to assist with adhesion as you apply the paper towels to the glued surface of the box. This process is messy and sticky and is a task for outside. 4) Once you are happy with your tarp job, it is time to allow it to dry thoroughly. This process can be aided by sitting the box in the hot water cupboard for 24 hours or so. Just be careful not to get the dripping sticky white goop on Mum’s clean towels! 5) Now that the PVA glue is fully dry, we can trim the excess paper from the bottom edge of the cardboard box and test fit our load on the trailer. 6) Applying a coat of Tamiya ‘Deep Green’ XF-26 will give our tarpaulin a realistic canvas look and effect. 7) Loaded and ready for its maiden voyage, our Ken Kirk Pilkington Automotive Glass Mercedes-Benz and matching semi with load is complete.

CREATIVITY ABOUNDS
Tristan
Our inaugural ‘Create a Truck’ competition has blown our expectations out of the water – you guys and gals have really got stuck into this. The level of imagination has been off the scale. Well done to everyone.
We have seen it all – from Kiwifruit slices as wheels right through to working LED headlights and disconnecting trailers complete with landing legs – and the list goes on. So as you can imagine, the judging was going to be difficult. But we had an ace up our sleeve – with good mate Craig Christensen stepping up to the plate as our guest judge. Thank you, Craig. Some of you will recognise Craig from the August 2022 issue of New Zealand Trucking magazine, where he featured on our Mini Big Rig pages. Our story on Craig’s model truck building abilities – creating model trucks out of household items and waste – was the very inspiration for this competition.
We also say a big thank you to the team at Italeri truck kitsets for coming on board as our sponsor and providing the major prizes. Italeri truck kitsets are an absolute pleasure to build, with accurately fitting parts and immense detail, so we are sure that our class winners will enjoy every minute of building their well-deserved prizes.
Without further ado, we bring you the contestants and winners of the inaugural 2022 ‘Create a Truck’ competition.
All we can say is bring on next year – we cannot wait to see what you dream up and build next time around.
