Khador Gun Carriage Assembly Guide

If you have never worked with resin models before, the gun carriage may seem like a daunting task. There are a few details to take note of, but assembling a large resin kit is not much different from a metal or plastic kit.

  1. As with any model kit, start by examining the contents. Lay out the parts and clean the flash and mold lines. The gun carriage contains both metal and resin parts. Cleaning the metal parts is easily done with clippers, a hobby knife and file. Use the clippers to remove large pieces of flash, and the knife and files to smooth out the mold lines.
  2. The resin parts will require a little more attention. Start with the chassis undercarriage. There are two rods between the wheel hydraulics that will need to be removed. You will also find some material at the back of the chassis that needs to be removed. This excess resin is the remains of the plastic sprue used to hold the part in place inside the silicone mold. Both of these are highlighted in red in the photo, and are easily removed with clippers.
  3. It is important to note that resin dust can be toxic if inhaled, so be sure to wear a dust mask when working with resin parts. Using a hobby knife to scrape the mold lines creates less dust than sanding or filing, so it is the recommended method, but there will be times that sanding is necessary. Once the excess sprue and rods have been clipped away, use a hobby knife to clean up the edges.
  4. If there is minor shift along the mold line, it may be easier to smooth the surface with modeling putty rather than try to scrape one side to make it level.
  5. The bottom of the carriage may be uneven due to the open pour method of casting. There will be a millimeter or two thick “lip” of excess resin that will need to be removed to ensure a level fit. Start by clipping away as much of the excess material as you can. Then, use a heavy grit sandpaper to smooth out the surface. If you have access to a small belt sander, it will make the work go much faster. Be sure to do the sanding outside and wear a dust mask. When the cleaning of the resin parts is finished, wash them with soap and water to remove any excess resin dust and to ensure that there is no mold release agent remaining on the part. The mold release can sometimes leave a greasy residue that may repel paint.
  6. Once the parts are cleaned, dry fit them to ensure they go together properly. There may be a small gap between the wheel hydraulics on the chassis and the body. This is easily overcome by cutting small spacers out of styrene card and fitting them in place to fill the gap.
  7. You may find it beneficial to leave the body of the gun carriage separate for easier painting of the chassis and horses. When attaching the wheels, the Formula P3 1.25mm Pinning Expansion is best for the heavy metal wheels.
  8. With the chassis complete and the horses assembled, check the fit on the base. It’s recommended to glue the wheels down first and then attach the horses.
  9. All that remains is to super glue the metal parts to the body, and the gun carriage is ready for priming and painting!
