Kitbashing or model bashing is a practice whereby a new scale model is created by taking pieces out of commercial kits. These pieces may be added to a custom project or to another kit. For professional modelmakers, kitbashing is popular to create concept models for detailing movie special effects. Commercial model kits are a ready source of "detailing", providing any number of identical, mass-produced components that can be used to add fine detail to an existing model. Professionals often kitbash to build prototype parts which are then recreated with lightweight materials.
Purposes, history, and methods
For the hobbyist, kitbashing saves time that would be spent scratch building an entire model. Hobbyists may kitbash to create a model of a subject (real or imaginary) for which there is not a commercial kit.
Although it has a long history, kitbashing came to the attention of a wider public via the fine modelwork seen in TV series such as Thunderbirds and the films 2001: A Space Odyssey and Star Wars Episode IV: A New Hope. Many of the spaceship models created for these programs incorporated details from tank, speedboat and car kits. Another example is the Batmobile from the 2005 film Batman Begins, as seen in the special features disc of the film's DVD.
Sometimes source kits are selected primarily due to kit quality, and sometimes because a kit closely resembles the desired model result. Kitbashing is common in sci-fi modeling.
It is not uncommon for parts to be cut and filed into shapes leaving gaps that are later filled with putty. Although a model with putty often looks unprofessional at an early stage, careful painting can completely hide defects. Textural details known as greebles may be added to enhance a model.
The popularity of ready-to-run, pre-assembled models, even coupled with the increased availability of many unique prototypes using resin castings, seems not to have seriously impacted the art of kitbashing.
Sometimes, kitbashing has been used to create works of art. The Toronto sculptor Kim Adams has used HO gauge freight cars, containers, detail parts, figures and scenery to create artistic landscapes. American artist Kris Kuksi also uses kitbashing to detail his maximalist sculptures.
A popular venue for kitbashing is diecast emergency vehicles such as fire apparatuses. Kitbashers often use models from manufacturers such as Code 3 and Corgi. The kitbash in such cases can be as simple as painting or redecaling a model, or as complex as tearing the model down and adding scratch-built components, followed by custom decals.
The UK wargames manufacturer Games Workshop encourages kit-bashing with its own product to create 'conversions' for its Warhammer Fantasy Battle and Warhammer 40,000 games. Over recent years its model designers have made an effort to make kits compatible with each other to make this easier for modelers.
An important aspect of kitbashing in model railroading is the reconfiguration of structure kits, most often to fit the geometry of a specific space. Walls can be shortened or lengthened, and/or corner angles changed to fit a given location on the layout. Another application is to use the wall parts to create a "flat", or shallow relief model to be displayed against the backdrop. For example, since it isn't needed in this case, the rear wall can be abutted to the front to double the length of the building; usually, but not exclusively, done with industrial structures. Plain sheet styrene or other material is typically added to the rear to strengthen the resulting model.
In model rocketry, kitbashing refers simply to using the pieces from a one kit to build a different model. This is typically used to create unusual and/or especially complex models.
With radio-controlled aircraft, such "kitbashing" can be done to either kitted aircraft as they are being built or more often, so-called "almost-ready-to-fly" (ARF) aircraft to change their appearance or flight characteristics to suit the owner. This can even extend to "plans-bashing", where a plans-built model has its construction plans partially re-drawn by the builder, either by hand or with CAD software before any part of the model's airframe has been fabricated from raw materials.
