Hi guys
I could really do with some help as I am new to fabrication and modelling. I'll tell you the situation – I need to fabricate some new wings and front air dam/spoiler for a project race car for next year but have never done this before. I was thinking the best way to make these is to make full scale models out of clay on the car so I know they fit etc. It also means I can get some of the detail correct (as it’s big). Although I have never worked with clay I am competent in the bodyshop and I have a good feel for form.
My approach is going to be to build the new wings on top of the old ones on the car and do both the front and the rear in pairs so that I can measure each side to ensure they ‘match’. I’m looking for advice on this process and also the process of then taking a mould from this to then start producing a fibreglass or carbon fibre panel. Any help would be appreciated.
Thanks

Hi Martin, Interesting project, if the surfaces that you are going to model are greater than the existing ones then apply a double sided tape to hold the clay in place. The clay can then be worked down to the desired shape with regular modeling tools. If the form falls below the existing shape, cut-out locally and use foam as a backing agent for the clay, then shape. I would assume that most of the shapes will be above the existing fenders (wings) for mechanical purposes. Before you start modeling make sure that the vehicle is set-up on hard blocks so that it doesn't sag under the weight of clay. Model one side of the vehicle first so that you get the balance correct before transferring your data. Template formers would be the quickest way to get similar shapes with the minimal amount of balance points. I guess you will be using the existing bolt patterns for re-mounting the fenders. For the air dam and spoiler, if you produce a base board and ground template a lot of the form can be dragged in, then hand finished. This process is explained on a previous thread, "new to clay modeling". This method is used for scale and full size vehicles alike. Let me know how you fare and I'll answer any problems that you encounter as your project progresses. If you can post pictures (Maybe confidentiality is a problem) it would be easier to explain most procedures. Steve A
