Auto
Union and Bugatti Conversions
|
At one of our Club meetings, I saw a 1/32 scale Porsche 917 model kit made by Matchbox that a couple of the club members were looking at. I knew Matchbox made models, but not of cars, and not in our favourite scale. Upon talking to them, they advised that these were not made anymore, but that they had some I could purchase. At
our next meeting I
acquired an Auto Union D type, and a Bugatti 59.
So the boxes were opened and I stared at the contents for a week or so. Due to the small width of the models, it was clear that I couldn’t use a donor chassis, which also meant that I had to find some way of holding the back axles in the correct position for the motors. On the drive to the NSCC Bishops Stortford Swap meet, I discussed this with one of the Club Members and his thoughts on the subject confirmed mine on attaching axle holders onto the motor sides in the style of the old 1960’s Formula Juniors. A couple of square sided motors were purchased, similar to those used in the Fiestas and Turtle Skateboards.Now came the thoughts on the chassis. I took all the main body parts of the models and sellotaped them into position. This greatly improved my visionary skills, in understanding how the conversion was to be performed, and whilst sitting in the garden, I found myself staring at the PVC cladding on the underside of my house roof. |

The tool I used most on the conversion was a one of the rotary, multi function hobby tools. To cut out the floor pan, I used a circular mini saw blade that was brilliant. For the filing down, I have various shaped attachments, and just used whichever shape best fitted the area I was working on. These tools can also be used as drills, and I have found so many uses for it on the cars, that I wouldn’t now be without it. These are now becoming cheaper each year, and although the attachments are not generally interchangeable between makes, you can "adapt" attachments to fit with some thought. One point though, is when filing, use a lower speed, as otherwise the plastic on the car melts rather than files. Back to the model. To hold the chassis in, I just used one screw attached to a body post, and allowed the axle holders to lean against a small amount of Milliput placed at the inside top of the rear wheel arches. For body posts I use raw plug strips, which come in lengths of about a foot, and in different colours to indicate different screw sizes. The white ones fit our screw sizes. The body of the model
was now painted, and I added some of the exterior details from the kit,
and a Cartrix driver figure. For the wheels, I used the ones supplied
with the kit, as these had rubber tyres. The wheel width was increased
using Milliput, otherwise there was very little for the axles to hold
onto.
For the Bugatti, I followed a similar approach, with a couple of exceptions. The axle holders had to be bent inwards, and then bent back outwards parallel to the motor, due to the small width at the rear of the model.

The main issue was that the Bugatti’s front wheels hung from underneath the model rather than came out of the bodywork. This meant that I couldn’t utilise a normal front axle, the guide had to be placed behind the wheels, and I had to ensure that the front wheels did not touch the track, as the model fixings would not stand up to the strain of running.
Just to show that things don’t always work correctly, and proving that it is not always best to make it up as you go along, I carefully cut away at the underside of the Bugatti’s front radiator grill so that the guide blade could turn, only to find that I hadn’t left any room for the wires. I ended up cutting more away, which has spoilt the front of the car. I should have fitted the guide behind rather than under the grill. A week after finishing these, I visited our local model shop, and saw brass strips that they sold. I think in hindsight, that I should have produced brass chassis, however, my next plan is to create a PVC chassis for one of my Modifieds, to see if there is any benefit, or future in the rest of the five and a half foot plank.

So there we are, these are never going to break any club lap records, but it’s two more cars for the collection. Derek Baker |
