Custom
Models - The RH90 Excavator

This is a
model that I have build from a kit by OHS. The first model is the
backhoe version, which is finished in a 2 tone blue/white colour
scheme. There is a lot of preparation required on the parts, especially
the white metal parts. There are over 100 parts in the kit and it
was a challenge to build, being my first full model that I have
ever done. The progress was slow at first but everything came together
towards the end.

The
picture on the left shows the internal engine compartment,
complete with 2 diesel engines and slewing motors. This picture has the hydraulic hoses removed to show the internal detail better.

This
picture shows the boom detail, including the photo etched
walkways and hydraulic block with pipework.
The
main boom parts are made from resin which does help
with the weight of the model. the hydraulic block and
rods/cylinders are made from white metal with rubber
tubing for the hydraulic hoses.

The
undercarriage is well detailed with rolling wheels,
idler and drive sprocket. The entire undercarriage is
made from white metal and gives good weight for stability.
The plastic tracks are individually linked with authentic
grouser and bolt detail.
|
The
rear of the model is well detailed with internal radiators
visible throught the counterweight cut-outs.
There
are hand rails running all the way around the model
which have been finished in blue which makes them stand
out.
