Macchi C.205 'Veltro' - (1:48 Tauro Model) Part 2

Welcome back.

In this second post on the Macchi build we will look at adding more detail to the firewall area.  Reference photographs show how busy this area is with all sorts of cables and pipes, most of which will be clearly visible through the wheel wells.

When adding this type of complex detail it is always a good idea to work in layers and plan ahead. W start by adding the detail that's in the background (closer to the firewall) and work our way outwards.  First of is a wiring loom that runs across the firewall itself.

This was done by twisting together four strands of very thin copper wire held together with a thin strip of aluminium sheet using superglue.  Once dry the excess aluminum is cut using a sharp blade:

After test-fitting the wire to the fire wall it is glued in place again using superglue.

The trick is to work in sections.  First the right-hand side end is glued in place.  Then the wire is bent to the desired position and glued again where it will change direction.  The process is repeated as many times as necessary.

Next some structural detail is added using thin plastic strips.

The next step is to prepare the largest bits of plumbing as these are very evident and will take up most of the space.  They will also dictate what other bits of detail will be allowed in this area.

The flexible piping is simulated by coiling thin copper wire around lengths of other wires of varying thicknesses.  Detail such as clips is added in a similar fashion to the wiring loom above.

These 'pipes' are bent to the desired position, using photographs for reference

At this stage it is very important to determine the sequence in which these bits of plumbing will be glued.  Their relative thickness implies that they are hard to bend around each-other so it is a good idea to jot down this sequence as you are dry-fitting the parts to see which should go in first.

Progress at this stage is somewhat slow, it literally takes hours to prepare and test fit the parts including the numerous corrections until the bends are just right!

That's all for now... thanks for watching.
