Tools

I use the following toolkit during cleaning and assembly of parts.


Wire Cutters/Snips (Flush)

Diamond Files

Locking C-Clamp

Clamps

Glue

To assemble these kits you should use a good quality superglue suitable for use on plastic. Regular Humbrol/Airfix/Revell type model kit glue will not work on the PLA plastic these models kits are made from.

Glue Application

I use an application pattern similar to this when affixing large flat pieces together such as the chassis & bed on the industrial wagons or inner & outer side halves.

This allows for a good glue coverage but minimizes the risk of air bubbles being trapped between the surfaces.

Paint

I primarily use Humbrol/Revell enamel paints to complete and detail my model kits. Results with acrylic paints can be disappointing for base colours since the plastic is non-porous although useful for non-permanent weathering.

You can also use a car bodywork primer (be careful to choose one designed for plastic for better adhesion) for easier aerosol application and the grey this is typically available in is quite suitable.

Preparation

Parts should arrive with their manufacturing sprues and supports already removed but will likely need a little cleaning up around the edges. During manufacture the very bottom of the model is pressed against a glass plate for adhesion and will often lead to a slight spreading of the plastic on this layer.

This is easily removed with a sharp craft knife or diamond file. When building a plank wagon kit this can be a useful side-effect when assembling the outer and inner faces of each side since you can glue them together then remove the excess to provide a seamless join.

Bearings/Bushings

The model parts are designed so that the bearing/bushings will be a snug fit in the hole and not require gluing in place due to possible glue ingress & contamination especially with such small bearings.

The spreading phenomenon described above can be a particular annoyance here as the plastic will slightly enclose the hole.

Step 1.


Using a sharp craft knife or diamond file you can remove the excess material from the lip of the hole and slightly chamfer the entrance.
 
Step 2.


Seat the bearing in the mouth of the hole as level as possible.

As you can see, the hole has been prepared/enlarged so the bearing is snug but not overly tight.
 
Step 3.

Use a set of C-Clamp grips to ensure an even pressure and gently ease the bearings into place.

Be careful! - too much pressure could damage the plastic or the bearing, you can aid the pressing home with a trace of oil if you wish.
 
Step 4.


The bearing face should finish flush with the plastic.

Wheels

The spreading phenomenon once again can pose an issue assembling the wheels. They will need to be prepared before attempting to fit to the axle.

Most diamond file sets contain a round file which is the perfect size (~3mm) to clean out the hole in the centre of the wheel before assembly. A 3mm drill bit can also be used.

Be careful not to affect the alignment of the wheel hole during cleaning, allow whatever tool you use to follow the lead hole - don't force it through.

Once the hole is sufficiently enlarged simply "scuff" a section on the axle using a file (this is to allow the superglue to gain a purchase on the otherwise smooth metal surface), assemble, space and allow to dry.
