1:14 Scale Custom RC Truck Model

This custom truck model was a fun build. The truck model came to us as an RC kit in 1:14 scale. Our model makers were tasked with transforming the generic body into a custom TMA truck for our client, Royal Truck & Equipment.

A TMA truck was driven to our model shop parking lot so the model makers could take measurements and pictures of the real thing. TMA trucks are used at road side construction sites, and are designed to absorb impact in the event of a collision from behind.

Thankful for Model Makers

Model Maker

Occasionally I like to take time out to acknowledge the work that model makers do, both here at KiwiMill and elsewhere. I spend most days in a support role at the model shop and I tend to take for granted what takes place every day. Then I talk to someone outside of the profession and realize it’s a pretty unique job.

Custom model makers build something different for each project they take on. In the shop right now, we have a hand-built 1:14 construction vehicle, a display stand with printed coats of armor, an oil well site, heating element models, a bread board design of a toy, a propane tank model and a vapor absorption machine.

Many of the models are for trade show use, sales or development, some for personal display and still others for teaching and instruction. Each one comes with its own unique needs that dictate how the model will be built.

Our model makers figure out the purpose of each model and then decide from there how to go about the build. Sometimes our model makers are given engineering drawings, sometimes simply a photograph. Often our model makers take pictures themselves of the real life object they need to replicate. Recently we had the real life object driven right to our parking lot for pictures!

Model makers need to know enough about each product, process, machine, landscape or structure to replicate what it looks like. Often they need to know what it looks like on the inside, such as with a cutaway model, and sometimes they must make it operate like the real item. That’s a lot of knowledge to accumulate for a 6 week build. Only to start all over again from scratch with the next project.

Getting to know each real word object intimately, in a short amount of time, is just one aspect of the model maker’s job. Engineering the model comes next. It’s not as simple as rebuilding it exactly as it was designed at the manufacturing stage. A model is built using its own unique principles. It is a representation of a real life object, not an exact design.

After the model design stage, materials and fabrication methods need to be chosen. A model maker, again, knows a lot about a wide range of materials and their properties. The same goes for fabrication methods. The tools in our shop are incredibly varied. CNC routers mix with table saws; 3D printers exist alongside a drill press and a lathe.

Knowing how to operate machines and hand tools safely and effectively is important. Being aware of how different materials react to each other – and the solvents used to bond them – is crucial. Once built and assembled, a well stocked paint booth and expert application of pigment allows our model makers to apply the finishing touches to a quality model.

It makes for exciting and varied work. Model makers have a willingness to tackle new projects. They need to be able to apply previous experience, and lessons learned, to a new challenge. Model makers are adaptable and resourceful.

Even as I write this, I can hear two model makers discussing electrical engineering for one of their latest projects that requires remote control movement. Today I am thankful to be in a work atmosphere with so much talent, knowledge and willingness to learn new things.

Rocket Launch Pad Scale Models

This was a two-part project involving rocket scale models and rocket launch pad scale models.

The rocket display scale models were built in 1:200th scale. They were mounted on black melamine bases for display purposes.

The second part of the project involved 1:200th scale rocket launch pad scale models. These large-scale models were made from a variety of materials. Tooling board and plywood were CNC routed for the bases. Sheet metal was welded to provide sturdy towers for the rocket launch pads. ABS and styrene added details. The treads were 3D printed.

Underground Storage Tank Cutaway Model

This underground storage tank cutaway model was commissioned for training purposes. It will help owners and operators understand the structure and parts of an underground fuel storage tank. It helps make sure they are staying in compliance with laws governing fuel storage.

Our model makers used client supplied diagrams and actual photographs of gas station pumps to create the cutaway model.

ABS, styrene, acrylic and 3D printed parts were combined to create this display. The resulting cutaway model conveys the information needed for training in an easily understandable way. It makes an effective visual aid.

Cutaway Model Build

A few weeks ago, KiwiMill finished another cutaway model. Model maker Mike created the 3D files necessary to 3D print some of the smaller, intricate parts. Meanwhile model maker Brian drew up parts for the CNC router to carve out big hunks of tooling board for the outer shells of the cutaway model. He also created files for the CNC mill, which made the patterned holes on some of the interior parts of the model.

The interesting thing about cutaway models is the glimpse into the inner workings of a product. In this case, the cutaway model has intriguing designs that make for a beautiful reveal. Painting each component a slightly different shade in the cutaway portion of the model further highlight the features. Of course, the signature company color on the exterior of the product attracts attention as well.

Take a look at the process:

 

What’s Inside a Cutaway Model?

 

Cutaway models are more than just a replica of your product.

Cutaway models reveal the inner features that would otherwise remain concealed.

At the same time, a cutaway model still provides the viewer a sense of the overall design.

It’s no surprise that cutaway models are a very popular way to represent a product when the inner workings are an important aspect of the sales pitch.

Show your potential customers what your product has to offer on both the outside and within – have a cutaway model built.

 

Reevaluating How We Ship Scale Models

Shipping Scale Models

KiwiMill has recently changed the way we are shipping scale models. Up till now, if a scale model fit into a hand-held travel case, it was usually shipped via commercial package delivery services, either ground or air, depending on time constraints.

However, after several random instances of scale models breaking in transit, we’ve reevaluated our policy. Before making changes, we first made sure our model construction process was not to blame.

The engineering of a scale model has much to do with its durability. KiwiMill designs models with the understanding that they need to be sturdy, not just look good. Especially our trade show models, which need to withstand frequent travel and handling.

Sturdy design means choosing the right materials, the strongest fasteners, and factoring in additional supports where necessary. So metal pieces are added to plastic for strength, soldering may be used for fastening rather than glue, and hidden braces may be placed at joints.

Great care is put into making sure a custom model is built durably, with accuracy, and all the artistic details expected from expert craftspeople. It makes sense to put just as much energy into the packing of the model for shipment.

Custom jigging is part of all model pack jobs. Many smaller models are placed in hard shell transport cases, with foam inserts that are hand carved to hold the model parts snug and secure. Medium sized models will have a custom built road case with wood jigging inside that is foam or cloth-lined. Larger industrial and architectural models are placed in hand built wooden crates that are jigged inside as well.

As professionals, we don’t want to jump to conclusions or assign blame if these  packed models are damaged in transit. Yet, when we see a continued pattern of beefy, guaranteed-for-life road cases sent back to us with flanges or handles broken off during transit, it’s hard to deny rough treatment occurred.

Our new solution? Every model is now shipped strapped to a pallet. Even if it’s in a road case, it gets strapped down to a pallet and goes freight. We’ve always used this method for larger models made in our shop. We are now using it for models we would have used package delivery service for in the past.

Architectural Model Presented to Donor

Recently KiwiMill built an architectural model of a campus building expansion. The donor was presented with this scale model of the school building as a thank you. Having an architectural model made of new real estate can be an effective way of showing appreciation for a donor, along with naming rights of the space.

This particular architectural model was made mostly from precision laser cut plastic. It has a unique brick texture that has been spray masked on to match the particular pattern used by the college.

The architects on this project wanted the option of showing the various HVAC parts that are commonly found on the roofs of buildings. While they are not often depicted in architectural models, KiwiMill built the scale HVAC equipment and provided the pieces loose, so they can be added to the model if desired.

 

 

 

 

 

Mining Equipment Models

Mining Equipment Models

 

KiwiMill recently completed a series of mining equipment models. Three of the models were replicas of conveyor type vehicles that are used to transport material from one site to another. One mining equipment model depicted a scale for weighing material.

All four mining equipment models were made primarily from 3D printed parts. Even the tires were 3D printed. Some laser cut acrylic was added to each model as well.

The models are transported in individual Pelican travel cases to trade shows and sales events.

Scale Model Specialization – Is It a Good Thing?

scale model

Some scale model shops specialize in particular types of models. Architectural model making is a common type of specialization, as well ship building or airplanes, here in the United States. Model trains would be another example of builders focusing on one specific genre.

KiwiMill, like many of today’s scale model shops, has chosen to market to a variety of industries in need of custom model designs. Custom model requests may come from the military, land developers, manufacturers, advertising agencies, product developers, private collectors, the medical field, museum and exhibit companies. Really, the possible sources for clients are endless.

Along with the variety of industries that require scale models, there are various types of models which are commissioned. Trade show models, cut-aways, display models, working models, training models, product models, prototypes and sales models are a few examples of the types of models requested by clients. The purpose of the model – what it is being used for – drives the type of model required, which then informs the model maker as to how to go about the build.

While specialization in a particular type of scale model building has its advantages – stocking materials, investment in fabrication methods, model maker training – at KiwiMill we believe a broad approach is more advantageous. Part of the allure of model making is its custom nature. Master model makers often thrive on the variety and challenge of each new job. Sameness is the antithesis of what many custom model makers are looking for in their work environment. Our model makers work best when presented with something new to build each project.

Providing the variety of custom model work that our team thrives on can be a challenge. Marketing to such a wide range of potential customers is daunting. Supplying the machines, tools, software and technology to build all types of custom scale models is an investment. Finding and stocking materials for each new job is an ongoing process. One job may require tooling board and brass piping, while the next project requires a source for fabric or tiny plastic footballs. A little bit of waste in regards to material left overs from previous jobs is to be expected.

Assembling a team of model makers who have the talent, training and abilities to make all kinds of models is important. It hasn’t been difficult for our scale model shop to find the combination of attributes that allow for creations of great depth and breadth. Some of our model makers have over 20 years experience with architectural models. Others have experience with prototypes and product development. Still others are engineers by nature and provide the CAD knowledge and mechanical expertise to draw up model parts and add movement, sound or lights.

The toughest part about deciding to build all types of custom models and not specialize in a particular type, is convincing the general public that we know what we’re doing. Our business is fortunate to have a large portfolio of varied work going back decades that we can share with potential clients. Yet, often we are asked to build a model of something that we haven’t done before. That’s the nature of the business – just about any object known to society can be replicated. It’s impossible to have examples to show for every request made. Reassuring customers that we can build a model of a product that we have never encountered before is part of our job.

What that means is that our satellite models are every bit as sophisticated as our museum dioramas. Our model makers can replicate a military all terrain vehicle as readily as they can recreate a piece of industrial equipment in the form of a cutaway. Not only are our model makers capable of making all types of models, representing all types of industry; they thrive on it.

 

 

Landfill Site Model

A local landfill is running out of space. They need a site model to show what the expansion will look like. The site model will be used to inform the local community as well as secure approval from local government.

Topographic maps are provided by the engineers of the landfill project and are used to build the site model. Our model makers have made use of Google images as well for the accurate depiction of the affected land.

The base of the site model is hand sanded foam. The landfill mass in the center of the model is drawn in a 3D computer program and then CNC routed. Flocking is added, along with laser cut roads.

The scale is 1″ = 200 ft. The site model covers a roughly 3/4 mile by 1/2 mile area.

The Difference Between Professional Model Makers and Hobbyists

model maker

The main difference between professional model makers and hobbyists?

It’s not necessarily talent. Many model maker hobbyists make BEAUTIFUL models.

It’s not access to specialized, expensive equipment and tools. A hand-built model, when done right, can be very polished looking and precise.

It’s not the materials used either – anyone has access on the internet to quality supplies.

It’s not even that professional model makers get a pay check. Hobbyists have been known to make money from their projects.

The biggest division is time. Professional model makers always work under deadlines – often very tight deadlines in the corporate world. The pressure can be fairly intense. A high quality replica needs to be built accurately and quickly to meet a client’s expectations and then it’s on to the next one.

Cutaway Models of Industrial Products

Cutaway models are a very popular way to display a product at trade shows. These two cutaway models show close up aspects of a full industrial skid shown in the 3rd picture.

By increasing the scale and adding cutaway features, these models seek to highlight key parts and processes of the overall skid. These products have special features that harness and convert energy. The cutaway models were made out of ABS plastic, tooling board, 3D printed material, plumbing hardware, and metal fixtures.
